摘要： An optical unit with shake-correction function is provided and includes: a movable body, a rotational support structure, a gimbal mechanism, a fixed body, and a rolling corrective-magnet drive structure. The rotational support structure, which supports the movable body to be rotatable around an optical axis, is rotatably supported by the gimbal mechanism around two axes intersecting with the optical axis. The rotational support structure includes a first annular groove provided on the movable body, a plate roller including a second annular groove facing the first annular groove, and multiple spherical objects inserted in the first annular groove and the second annular groove. The gimbal mechanism supports the plate roller to be rotatable. The rolling corrective-magnet drive structure, which rotates the movable body around the optical axis, includes a rolling corrective magnet on the movable body side, and two rolling corrective coils on the fixed body side.

摘要： The actuator includes a movable body and a support body, first and second connecting bodies connected to the movable body and the support body, and a magnetic drive circuit. The movable body includes a first yoke including a first flat plate portion overlapping a coil from a Z1 direction, and a pair of first connecting plate portions extending from both ends of the first flat plate portion in a Z2 direction, and a second yoke including a second flat plate portion overlapping the coil in the Z2 direction and a pair of second connecting plate portions extending from both ends of the second flat plate portion in the Z1 direction. The first yoke and the second yoke are assembled by press-fitting the pair of second connecting plate portions into the pair of first connecting plate portions.

摘要： An actuator includes a support body, a movable body, a connection body, and a magnetic drive mechanism having a coil and a magnet for relatively moving the support body and the movable body. A winding part of the coil includes effective side portions, a first curved side portion connecting one side ends of the effective side portions, and a second curved side portion connecting the other side ends of the effective side portions. The magnet faces the effective side portions of the coil. A yoke fixed to the magnet includes a first yoke, a second yoke, a one side connection yoke and the other side connection yoke connecting the first yoke with the second yoke, and the one side connection yoke and the other side connection yoke are provided at positions so as not to overlap with the effective side portions and the magnet.

摘要： An optical unit includes a movable body with an optical module; a fixed body; a gimbal mechanism having a hole portion through which at least a part of the optical module passes, and serving as a support mechanism that swingably supports the movable body with respect to the fixed body in a direction intersecting an optical axis direction as a pivot axis; and a drive mechanism having a coil and a magnet, and configured to move the movable body with respect to the fixed body. One of the coil and the magnet, as a movable body drive mechanism, is provided on a lateral portion of the movable body in a direction intersecting the optical axis direction. The hole portion is provided with a size such that at least a part of the movable body drive mechanism is visible through the hole portion when viewed from the optical axis direction.

摘要： 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.
