Patent ID: 7766345

Claim:
A telescopic actuator comprising: a housing; an output rod which is slidable in an axial direction with respect to the housing; at least two slide bearings via which the output rod is supported by the housing; a sensor to detect a position of the output rod, wherein the sensor includes a detectable portion disposed between the two slide bearings and attached to an outer peripheral surface of the output rod; a ring-shaped stopper disposed between the two slide bearings and provided on the outer peripheral surface of the output rod such that the ring-shaped stopper is closer to an end portion of the housing than from the sensor, wherein the ring-shaped stopper moves in the axial direction together with the output rod and regulates a moving end position of the output rod; and an end member detachably attached to an end portion of the housing, wherein the end member comprises a contact surface, and the ring-shaped stopper regulates the moving end of the output rod by contacting the contact surface, wherein one of the two slide bearings that is closer to the end portion of the housing than from the other is supported by the end member.
