<p>An actuator (1) has a gear case upper part (2), a gear case lower part (3), a resin inner pipe (5) supported movably and a DC motor (6). The gear case upper part (2) and the gear case lower part (3) are configured to be divided into two parts along the central axis of the inner pipe (5). A gear case (4) configured by the gear case upper part (2) and the gear case lower part (3) is integratedwithapedestal (43) for attaching the DC motor (6) thereto, a gear storage part (42) for storing a worm gear (61) and a worm wheel (14), and limit sensor storage parts (81, 91) for storing limit sensors (8, 9) that detect limit location of the inner pipe (5).
