Abstract: An actuator includes a cover that houses a movable body. The cover is divided into two parts: a first cover member and a second cover member. A first comb teeth portion disposed at the end of the first cover member and a second comb teeth portion disposed at the end of the second cover member slidably engage each other in a first direction. Therefore, the first and second cover members can be assembled by adjusting the gap between the cover and the movable body in which a connecting member connecting the movable body and the cover is disposed, so that the dimensional accuracy of the gap between the cover and the movable body can be improved. Therefore, the movable body and the support body can be securely connected, and assembly defects can be avoided. Moreover, excess compression of the connecting member can be avoided.

Abstract: An actuator includes a magnetic drive circuit to vibrate a movable body relative to a support body. The magnetic drive circuit includes a magnet disposed in the movable body and a coil disposed in the support body. The support body includes a metal cover housing the movable body and a metal coil holder holding the coil. Two guide portions disposed on the coil holder are in surface contact with a first surface and a second surface of the cover. The heat generated when the coil is energized is transmitted from the coil holding portion to the guide portions and dissipated to the outside from the cover, which is in surface contact with the guide portions. Therefore, the temperature rise of the coil can be suppressed.
