<P>PROBLEM TO BE SOLVED: To provide a linear actuator with dust resistance, water-proof and drip-proof, capable of reducing a labor of attachment to various devices and facilitating downsizing. <P>SOLUTION: A linear actuator comprises: a cylindrical stator 2 provided inside a case 1; a vibrator 3 elastically supported on the case 1 through an elastic body 4 in the state of being arranged inside the stator 2 and reciprocally movable to the stator 2 by an alternating magnetic field caused by energization to the stator 2; a pair of regulation parts 5 provided on both outer sides of the vibrator 3 in a direction of reciprocal movement inside the case 1 and provided contactably with the vibrator 3 so as to regulate a movement region of the vibrator 3; and a control base 6 provided in a region between the pair of regulation parts 5 or at a height position overlapping with at least one regulation part 5b when viewed in a direction orthogonal to the direction of reciprocal movement without interfering with the vibrator 3 inside the case 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
