A cylinder device includes a piston and a piston rod disposed movably, and a movable body in which another end portion of the piston rod is inserted. The piston rod includes a first pin groove that extends along an axial direction and through which a support pin is inserted. The support pin is also inserted through second pin grooves formed in the movable body and having a substantially L-shaped cross section. Further, a link pin is inserted through a pin hole on the other end portion of the piston rod. The link pin is inserted through third pin grooves in the movable body which are inclined at a predetermined angle with respect to the axis of the movable body. In addition, under a moving action of the piston, the movable body is displaced linearly, and thereafter, is rotationally displaced by the link pin moving along the third pin grooves.
