ABSTRACT:
A device for temporarily fixing a horizontal swing arm used for a car lift apparatus includes a horizontal hollow cylinder connected to the swing arm at its one end portion, a horizontal cylindrical solid rod having one end slidably and rotatably supported in the other end portion of the hollow cylinder, and a cylindrical vertical rod extending through a horizontal bracket projecting from a carriage to which is connected the swing arm and which is connected to a post for vertical movement. The horizontal hollow cylinder and the horizontal cylindrical solid rod are located along the outside of the horizontal swing arm and in alignment with each other. The vertical rod is rotatable about its vertical axis as well as vertically movable. The horizontal rod is connected to the vertical rod at its other end. The hollow cylinder is provided with a lock pin projecting into the cylinder, while a plurality of slots are formed on the circumference of the horizontal rod so that one of the slots may be engaged with the lock pin.
