A vehicle includes a power unit with an engine that transmits drive force forward and backward to front and rear wheels via propeller shafts. The power unit is supported on a vehicle frame by engine mounts provided at three locations. An engine mount on one side of a crankshaft is farther from the center of gravity of the power unit than the other two mounts. This engine mount joins the crank case and the vehicle frame. The two other engine mounts on the other side of the crankshaft are closer to the center of gravity. These engine mounts join the vehicle frame and front and rear ends of an engine hanger that is joined to the crank case and extends forward and backward beyond at least one of a front end and a rear end of the crank case.

1. A power unit support structure for an off-road vehicle comprising: a power unit in which a drive force distributor mechanism that distributes the drive force of an engine to the front and rear is provided at least to the front or the rear of a longitudinal engine layout that has a crankshaft that is rotatably supported by a crank case and extends in a front-to-back direction of the vehicle, and drive force is transmitted from the drive force distributor mechanism to front and rear wheels via propeller shafts; anda vehicle frame that supports the power unit, supports the front and rear wheels, and is capable of traveling off-road carrying multiple passengers and cargo; whereina power unit support mechanism is provided in which the power unit is supported on the vehicle frame using a total of three engine mounts, one provided on one side of the crankshaft of the crank case, and two provided on another side;the one engine mount on one side, which is disposed a first distance from a center of gravity of the power unit, joins the crank case and the vehicle frame; andthe two other engine mounts on the other side, which are disposed a second distance from the center of gravity of the power unit, join the vehicle frame and front and rear ends of an engine hanger joined to the crank case and extending forward and backward beyond at least one of a front end and a rear end of the crank case;wherein the second distance is less than the first distance. 2. The power unit support structure for an off-road vehicle according to claim 1, wherein: the drive force distributor mechanism is provided either to the front or the rear of the crank case, and a propeller shaft for transmitting drive force to either the rear wheels or the front wheels extends through a side surface of the crank case; andthe engine hanger extends forward and backward roughly parallel to the propeller shaft so as to sandwich the propeller shaft between the engine hanger and the crank case. 3. The power unit support structure for an off-road vehicle according to claim 1, wherein: each of the three engine mounts of the power unit support mechanism comprises a bracket and damping material joined to the bracket by an attachment bolt, the attachment bolts all extending in the front-to-back direction of the vehicle. 4. The power unit support structure for an off-road vehicle according to claim 1, wherein the engine hanger comprises: an engine attachment section, having a U-shaped cross section, that is fastened at a plurality of locations to a boss projecting from the crank case, the boss being sandwiched by front and rear walls;front and rear mount-supporting sections for supporting the front and rear engine mounts; anda plurality of linking pipes that connect the front and rear mount-supporting sections and extend joined to front and rear walls of the engine attachment section. 5. The power unit support structure for an off-road vehicle according to claim 4, wherein: the engine attachment section of the engine hanger is provided with a space between two joining sections that join with the boss of the crank case, and the propeller shaft runs through the space. 6. The power unit support structure for an off-road vehicle according to claim 1, wherein: one of the engine mounts provided to the front and rear of the engine hanger is joined to the power unit, and the other engine mount is joined to the vehicle frame;the engine mount joined to the power unit is provided with a roughly horizontal receiving surface on a joining section of a vehicle frame bracket for joining to the vehicle frame; andthe engine mount joined to the vehicle frame is provided with a roughly horizontal receiving surface on a joining section of a power unit bracket for joining to the power unit. 7. A power unit support structure for a vehicle comprising: a power unit comprising an engine having a crankshaft, the power unit having a center of gravity;a vehicle frame that supports the power unit;a power unit support mechanism for supporting the power unit on the vehicle frame through a total of three engine mounts positioned lower than the center of gravity of the power unit;wherein one of the engine mounts is positioned on one side of the crankshaft, and the other two engine mounts are positioned on the other side of the crankshaft, and wherein the one engine mount is farther from the center of gravity of the power unit than the other two engine mounts. 8. The power unit support structure of claim 7, wherein the crankshaft is rotatably supported by a crank case to extend in a front-to-back direction of the vehicle. 9. The power unit support structure of claim 8, wherein the one engine mount joins the crank case and the vehicle frame. 10. The power unit support structure of claim 9, wherein the other two engine mounts join the vehicle frame and front and rear ends of an engine hanger joined to the crank case. 11. The power unit support structure of claim 10, wherein the engine hanger extends forward and backward beyond at least one of a front end and a rear end of the crank case. 12. The power unit support structure of claim 7, wherein each of the three engine mounts is attached by an attachment bolt that extends in a front-to-back direction of the vehicle. 13. The power unit support structure of claim 7, wherein the power unit further comprises a drive force distributor mechanism that distributes drive force of the engine to the front and rear of the vehicle, and drive force is transmitted from the drive force distributor mechanism to front and rear wheels via propeller shafts. 14. A power unit support structure for a vehicle comprising: a power unit comprising an engine having a crank case supporting a crankshaft;a vehicle frame that supports the power unit; anda power unit support mechanism for supporting the power unit on the vehicle frame through a total of three engine mounts, each of the engine mounts being attached by an attachment bolt that extends in a front-to-back direction of the vehicle;wherein one of the engine mounts joins the crank case and the vehicle frame, and the other two engine mounts join the vehicle frame and front and rear ends of an engine hanger joined to the crank case. 15. The power unit support structure of claim 14, wherein the one engine mount is positioned on one side of the crankshaft, and the other two engine mounts are positioned on the other side of the crankshaft. 16. The power unit support structure of claim 14, wherein the one engine mount is farther from a center of gravity of the power unit than the other two engine mounts. 17.
