An actuator having sufficiently high detection accuracy while having a simple configuration is provided. An actuator includes a cylinder (51), a piston (52) that moves inside the cylinder (51), a stroke sensor (53) that detects a position of the piston (52), an edge portion (51a1) that restricts rotation to one side, and a restriction protrusion (51b) that restricts rotation to the other side. The amount of rotation allowed by the edge portion (51a1) is larger than the amount of rotation allowed by the restriction protrusion (51b). A center of a sensor (53c) of the stroke sensor (53) is shifted to one side from a center of a member to be detected (53b) fixed to the piston (52).
