ABSTRACT:
A third wheel collapsing device for a golf club cart includes a third wheel support unit consisting of a connect base having a fitting member with an upper inclined surface, and a lock block on the upper inclined surface. A spring chamber is continually formed in both the fitting member and the lock block for receiving a spring therein. A control rod is movably fitted in a center hole of both the fitting member and the lock block and through the spring, and has its lower end pivotally connected with an eccentric plate. The eccentric plate is swung up or down to move down or move up the control rod so that the lock block is also moved down to alters its position a little to firmly contact with an inner surface of a main frame of a golf club cart or to separate from the main frame, assembling or disassembling the third wheel support unit with or from the main frame.
