1. A wheel of a golf cart, comprisinga connecting member coupled to a support part of a main frame of a golf cart; the connecting member having two juxtaposed parallel lateral walls; the connecting member having a tube portion extending from an outer side of one of the lateral walls to an inner side of other of the lateral walls; the tube portion having a gap between the lateral walls; an axle having an annular engaging recess near to a first end thereof; the axle being detachably inserted in the tube portion of the connecting member with the annular engaging recess opposing the gap of the tube portion; a rotary main body separably connected to the axle; and an engaging element for blocking movement of the axle away from the tube portion of the connecting member; the engaging element having an operated block, and an engaging plate projecting from the operated block; the engaging element being arranged between the lateral walls, and pivoted to the connecting member by means of a pivotal element supported on the lateral walls such that the engaging plate opposes the gap of the tube portion as well as the annular engaging recess of the axle; the engaging element being connected to a torsion spring; the torsion spring being positioned around the pivotal element, and hooked on an upper portion of an outward edge of the engaging plate, and a bottom of the connecting member at two ends thereof respectively, such that the engaging plate is normally biased towards, and fits in the gap of the tube portion as well as the annular engaging recess of the axle. 2. The wheel of a golf cart as claimed in claim 1, wherein the connecting member is formed with two board parts respectively above, and under the tube portion; each of the board parts having a gap opposing the gap of the tube portion for allowing the engaging plate of the engaging element to pass through to fit in the gap of the tube portion.3. The wheel of a golf cart as claimed in claim 1, wherein the connecting member is provided with a cover, and the lateral walls have hook holes thereon; the cover having hooks projecting from edges thereof; the cover being disposed next to edges of the lateral walls to cover a space between the walls with the hooks being hooked on the hook holes.4. The wheel of a golf cart as claimed in claim 3, wherein the lateral walls of the connecting member are formed with elongated projections, which define guiding trenches together with the board parts, and the hook holes are formed on the guiding trenches.5. The wheel of a golf cart as claimed in claim 1, wherein the operated block of the engaging element has a concavely curved upper side.6. The wheel of a golf cart as claimed in claim 1, wherein the rotary main body has a disk portion, a tube portion projecting from a middle of the disk portion, and a cap coupled to a tail end of the tube portion while the axle has an annular trench near to other end, and is provided with a sleeve;the tube portion of the rotary main body having an annular protrusion on an inner side thereof; the cap having an axial hole; the sleeve including a main part, and a subsidiary part separable from the main part and capable of forming a cylindrical hole together with the main part; the main part having a left section, and a right section; the left section being thicker than the right section; an outward side of the left section projecting farther than an outward side of the right section such that a shoulder is formed at an intermediate portion of the main part; the subsidiary part having a left section, a right section, and a trench between the left and the right sections thereof; the subsidiary part having a connecting hole extending through the right section thereof; the subsidiary part having a rod connected to the connecting hole and projecting from an inward side thereof; the axle being passed through the tube portion of the rotary main body, with the first end projecting from the axial hole of the cap; the sleeve main part and the subsidiary part being inserted in the tube portion of the rotary body from the right sections thereof with the trench of the subsidiary part being over the inner annular protrusion of the tube portion of the rotary body, and with an inward end of the rod of the subsidiary part being inserted in the annular trench, and with the shoulder of the main part abutting the inner annular protrusion for supporting the axle in between. 7. The wheel of a golf cart as claimed in claim 6, wherein the rotary main body is provided with a cover, and has a plurality of through holes on the disk portion around the tube portion thereof while the sleeve main part has an abutting post projecting from a tail end of the left section thereof; the cover having a plurality of hooks on an edge thereof; the cover being joined to the disk portion with the hooks being passed through the through holes, and hooked on the disk portion; the abutting post of the sleeve main part contacting the cover of the rotary main body after the cover is joined to the disk portion.
