Abstract: Rotation of a rotating member to a predetermined rotational position is properly regulated by a regulating member even when a thickness of the regulating member in a rotating shaft direction is made smaller. In a steering lock device, a pair of restricting portions formed in a release frame of a release link is disposed at both-sides of a link in front- and rear-direction, so restricts tilt of the link to both-sides in the front- and rear-direction. For this reason, even if thickness of the link in the front- and rear-direction in the vicinity of the shaft is made smaller, when rotation of a cam shaft from an “ACC” position to a “LOCK” position is regulated by the link, tilt of the link to both-sides in the front- and rear-direction can be suppressed, so that the link can properly regulate rotation of the cam shaft from the “ACC” position to the “LOCK” position.
