Abstract
A third wheel collapsing device for a golf club cart includes a third wheel support frame having a U-shaped frame fixed pivotally with a third wheel and a hollow support arm fitted therein with a fit block. The support arm and the fit block respectively have insert holes and connecting holes. A support base assembled on the support arm has a pivotal shaft under the bottom and a threaded hole before the pivotal shaft for receiving an elastic lock member, which has an engage rod biased by a compression coil spring and controlled by a user. The support base has a fastening frame fixed with the lower end of the main frame of a golf club cart. When the engage rod is pulled and removed from the first insert hole of the support arm and the first connecting hole of the fit member, the third wheel support frame can be transversely collapsed.
