Claims

[Scope of utility model registration request]

A main body that is fixed to a predetermined base surface and has a through hole extending in a direction substantially along the base surface; a wedge-shaped member that is housed on the base side and has a slope that gradually approaches the front end in the advancing and retreating direction with respect to the opposite surface thereof; an advancing and retreating drive unit that is connected to the rear end of the wedge-shaped member; and the through hole. It is housed on the base side of the wedge-shaped member inside so as to be able to advance and retreat in the direction of the through hole, and has a pressure receiving surface consisting of a slope in contact with the slope, and the tip of the surface on the base side is formed as a pressing part, and the pressing part a pressing member having a plurality of trochanters that protrude rearward from the part toward the base and are supported via springs so as to come into contact with the inner surface of the through hole; A clamping device comprising an interlocking means provided so that only the wedge-shaped member moves forward along with the movement, and so that the wedge-shaped member moves back together with the pressing member from the middle of the retreat of the wedge-shaped member by the drive unit.
