Abstract: A linear drive portion is fixed to a piston. A nut portion and a screw portion relatively rotate, and a direction of action of driving force is converted between a rotational direction and a linear direction. The piston is installed within a case. The inner circumference of a piston sliding portion fixed within the case slidably supports the outer circumference of the piston. The nut portion is displaced with the piston, and the screw portion rotates in conjunction with a rotational drive portion. The piston is installed so as to be able to slide in the axial direction of the case with respect to the piston sliding portion. The axis of the piston and the central position of the inner circumference of the piston sliding portion are set to be eccentric with respect to the axis of the screw portion and the nut portion.

Abstract: A set of a bolt and a nut having a rotation prohibiting mechanism comprises a foldable part (30) at the tip of a bolt (20), that can be folded around an axis perpendicular to a bolt axis. A tip portion (30) can be folded to either sides with the direction extending along the bolt axis as a center. Grooves (18a-18g) for storing the foldable part (30) are formed on a tip surface (a surface from which the tip of the bolt projects out when the bolt and the nut are tightened) of the nut (12) or the knob (18). A number of the grooves is an odd number. The grooves are arranged radially with equal angular intervals with a center at a screw hole of the nut. For example, seven grooves are arranged radially with equal angular intervals. In this case, the angle between adjacent two grooves is about 51.4 degrees, and this angle is to be an expected angular resolution of the rotation prohibition. However, according to the above mentioned set of the bolt and the nut, the expected angular resolution can be halved (i.e. 25.
