Abstract
A clamp jig has a positioning pin provided at the tip of a cylindrical member, and a clamp arm is mounted in a slit formed in this positioning pin, so as to be able to swing and so as to be able to axially advance and retreat. A reciprocating shaft is connected to the clamp arm by a connecting pin, and a spring force is applied to this reciprocating shaft in a retreating direction by a compression coil spring. A plunger 35 brought into contact with the reciprocating shaft is mounted in a drive housing so as to be able to axially reciprocate, and a female screw member driven by a motor is thread-connected to a male screw member secured to this plunger. Accordingly, it is made possible to reliably perform positioning and clamping, of a member to be fixed, and unclamping thereof by a low-cost motor.
