ABSTRACT:
A folding mechanism of a golf cart includes a fixed member secured to a middle rod part of a golf cart frame, first and second moving members joined to upper and lower rod parts of the frame respectively, and a spring-biased pivotal plate. The moving members each have a toothed portion, which has an engaging protrusion at one end. The toothed portion of the first moving member further has a stop portion. The moving members are pivoted to the fixed member, and engaged with each other such that angular displacement of one of the moving members will cause angular displacement of the other. The golf cart will be fixed in a stretched position when the engaging protrusions engage. The pivotal plate is normally in a first position, in which position the front end thereof will engage the toothed portion of the first moving member to prevent the golf cart from folding.
