Claims

[Scope of utility model registration request]

A pair of swivel cam plates are rotatably attached to a position where they are engaged with and disengaged from a stopper pin protruding from the reciprocating body, and the pair of swivel cam plates are biased to swivel and protrude onto the movement path of the stopper pin. A spring is attached, and each swing cam plate is provided with a swing cam surface that allows the swing cam plate to swing backward by the stopper pin against the biasing force of the spring, and a stop cam surface that prevents movement of the stopper pin, The swivel cam surface of the swivel cam plate is pushed by the stopper pin and pivoted away only when the movable body moves forward, and the swivel cam surface of the other swivel cam plate is pushed by the stopper pin only when the movable body moves backward. The stop cam surface of the one swing cam plate prevents movement of the stopper pin only when the movable body moves back, and the stop cam surface of the other swing cam plate prevents the movement of the stopper pin when the movable body moves backward. A fixed position stopping device for a reciprocating body, which prevents movement of a stopper pin only during movement, and has a shape in which each stop cam surface cooperates to clamp the stopper pin.
