A transaxle apparatus provided with a planetary gear type differential The differential comprises a pair of co-axial axles, a sun gear, a center gear serving as a driving input gear, a pair of carriers, a pair of ring gears serving as steering input gears, and planet gears. The center gear interlock
A transaxle apparatus provided with a planetary gear type differential The differential comprises a pair of co-axial axles, a sun gear, a center gear serving as a driving input gear, a pair of carriers, a pair of ring gears serving as steering input gears, and planet gears. The center gear interlocks with the sun gear. The pair of carriers are fixedly disposed around the respective axles oppositely to each other with respect to the center gear. The pair of ring gears are rotatably disposed around the respective carriers so as to slidably abut at their inner peripheral surfaces against outer peripheral surfaces of the respective carriers. Each of the ring gears is extended between the sun gear and each of the carriers disposed in the ring gear so as to be inner peripherally formed into an internal gear. Each of the carriers is integrally provided with a plurality of projections projecting toward the center gear between the sun gear and the internal gear. The planet gears are rotatably disposed around the respective projections of the carrier so as to engage with the sun gear and the internal gear. The projection is preferably formed of the carrier. Tips of teeth of the internal gear are extended toward the axis of the axle further than the inner peripheral surface of the ring gear slidably abutting against the outer peripheral surface of the carrier.

The device as in claim 1, wherein said handle includes a grippable portion extending generally transverse to a longitudinal axis of said elongate shaft. 10. The device as in claim 1, wherein said notch is generally correspondingly shaped to receive a round golf ball. 11. The device as in claim 1, wherein said handle is configured to facilitate a one-step three-point grip, wherein an operator's index and middle fingers are approximately one inch apart from each other. 12. A method of determining a numeric designation of a green's speed and testing the speed of a putting surface, said method comprising the steps of: (a) providing a greenspeed measuring device having an elongated shaft, said shaft having a release end and a handle end opposite said release end, said shaft including a bottom side surface and a top side surface, a ball rolling channel extending from said release end toward said handle end, said channel being defined in said top side surface, a notch defined in said top side surface adjacent said channel, and a handle attached to said shaft at said handle end; (b) Placing a first golf ball in said notch and slowly raising said handle end away from the putting surface while maintaining said release end in contact with the putting surface until said golf ball moves out of said notch into said channel and rolls down said channel toward said release end and onto the putting surface; (c) Repeating step (b) at least two more times; (d) Measuring the average distance that said golf balls rolled on the putting surface from the point at which said release end was in contact with the putting surface; (e) Repeating the above steps (b)-(d) from the general area which the first said golf ball came to rest so that a second set of golf balls is caused to roll generally in the opposite direction on the putting surface; (f) Measuring an average distance of the second set of golf balls and calculating the average distance said balls rolled in each direction; and (g) Utilizing said handle end of said greenspeed measuring device to strike a ball on a green to simulate at least one putt to a selected target on the putting surface. 13. The method as in claim 12, including the step of first selecting a flat area of the putting surface, and wherein three said golf balls are rolled and measured in each direction. 14. The method as in claim 13, including utilizing a level mounted to said bottom side surface of elongated shaft to find a flat area of the putting surface. 15. The method as in claim 12, wherein said target includes an existing hole location or a prospective hole location, and wherein said handle end includes a heel-toe weighted putter head. 16. The method of claim 12, wherein said step of slowly raising said handle end away from the putting surface includes the use of a three-point grip on said handle. 17. A greenspeed measuring device for quick and accurate measurement of the speed at which a golf ball will roll over a putting surface, said greenspeed measuring device comprising: an elongated shaft defining a longitudinal axis therethrough, said shaft having a release end and a handle end opposite said release end; a ball rolling channel defined parallel to said longitudinal axis and extending from said release end toward said handle end; a ball holding notch, wherein at least a portion of said notch is radially displaced from said longitudinal axis, said notch being adjacent said channel; and means for gripping said handle and of said elongated shaft, said means for gripping including a putter head. 18. The device as in claim 17, wherein said means for gripping includes a handle mounted to said handle end, and wherein at least a portion of said handle extends radially outward from said longitudinal axis a distance of at least one inch. 19. A greenspeed measuring device for quick and accurate measurement of the speed at which a golf ball will roll over a putting surface, said greenspeed measuring device comprising: an elongated shaft defining a longitudinal axis therethrough, said shaft having a release end and a handle end opposite said release end, a bottom side surface and a top side surface, and wherein said bottom side surface defines a tapered surface at said release end; a generally V-shaped ball rolling channel defined parallel to said longitudinal axis and extending from said release end toward said handle end; a ball holding notch adjacent said channel, wherein at least a portion of said notch is radially displaced from said longitudinal axis, wherein said ball holding notch is generally correspondingly shaped to receive a round golf ball; and a heel-toe weighted putter head mounted to said elongated shaft at said handle end to facilitate one-step gripping and raising of said handle end of said device. 20. The device as in claim 19, including a level mounted to said bottom side surface; and a tape measure fastened to said release end. 21. A method of determining a numeric designation of a green's speed and testing the speed of a putting surface, said method comprising the steps of: (a) Providing a greenspeed measuring device having an elongated shaft, said shaft having a release end and a handle end opposite said release end, said shaft including a bottom side surface and a top side surface, a ball rolling channel extending from said release end toward said handle end, said channel being defined in said top side surface, a notch defined in said top side surface adjacent said channel, and a handle attached to said shaft at said handle end; (b) Placing a first golf ball in said notch and slowly raising said handle end away from the putting surface while maintaining said release end in contact with the putting surface until said golf ball moves out of said notch into said channel and rolls down said channel toward said release end and onto the putting surface; (c) Repeating step (b) at least two more times; (d) Measuring the average distance that said golf balls rolled on the putting surface from the point at which said release end was in contact with the putting surface; (e) Repeating the above steps (b)-(d) from the general area which the first said golf ball came to rest so that a second set of golf balls is caused to roll generally in the opposite direction on the putting surface; and (f) Measuring an average distance of the second set of golf balls and calculating the average distance said balls rolled in each direction, wherein said target includes an existing hole location or a prospective hole location, and wherein said handle end includes a heel-toe weighted putter head.
