ABSTRACT:
A stopper which has a rod projected from the lower end opening in a hollow body to be slidable in upward and downward directions and mounted to be urged by the lifting force of a spring, a pedal attached to the rod, and an actuator formed symmetrically with recesses and rotatably supported to one side of the rod. The body is formed with a guide slot 8 adapted so that the actuator is disposed in a predetermined direction slidably in upward and downward directions therein, a rotary controller for rotating the actuator in a predetermined angle, and a connector for engaging the actuator at a predetermined angle, the rod formed to be able to be axially contracted and elongated and returned. Thus, the stopper can lock and release the lock merely by depressing the pedal, thereby improving the operability and permitting locking in a predetermined stroke.
