Abstract: A movable body may be in a unit with a shake correction function having a movable body, a fixed body provided with a support mechanism structured to swingably support the movable body, a shake correction drive mechanism, and an elastic support member which connects the movable body with the fixed body. A tilt adjusting method for the movable body may include setting a state that a force having a component on an opposite direction to a driving force of the shake correction drive mechanism is acted on the movable body, adjusting the driving force so that a tilt direction of the movable body is substantially coincided with a target direction, and connecting the movable body with the fixed body through the elastic support member in a state that the tilt direction of the movable body is substantially coincided with the target direction.

Abstract: An actuator and a tactile device are provided. In the actuator, a gel member is disposed in a portion where a support body and a movable body face each other. The gel member is attached to the movable body and the support body by a first adhesive layer and a second adhesive layer. The gel member includes a first portion and a second portion having a higher hardness than an intermediate portion on a first adhesive layer side and a second adhesive layer side from the intermediate portion. If the thicknesses of the first adhesive layer and the second adhesive layer are changed, a spring constant of the gel member is changed. The first adhesive layer and the second adhesive layer are made to appropriate thicknesses. The gel member, the first adhesive layer and the second adhesive layer are addition reaction types, and the base polymers thereof are the same.

Abstract: The present disclosure provides an optical unit with shake correction function capable of preventing a thrust receiving member, which fixes a sphere, from falling off from the movable body in an optical axis direction. According to some embodiments of the present disclosure, a thrust receiving member to which a first sphere is fixed is held by a holding portion formed of the cutout recess provided in a fixed body. A bottom wall surface of the holding portion makes contact with a bent plate portion of the thrust receiving member from −Z direction side. Further, locked surface parts provided on a pair of side wall surfaces of a holding portion make contact, from +Z direction side, with a pair of locking plate portions protruding from a bent plate portion in circumferential direction in the thrust receiving member.

An outer peripheral face of the coil holding member may include a side-face pair comprising a first side face and a second side face which are substantially parallel to each other. The first side face may be formed with a first protruded part around which the first coil is wound, the first protruded part being protruded to an outer peripheral side with respect to the coil holding member. The second side face may be formed with a second protruded part around which the second coil is wound, the second protruded part being protruded to an outer peripheral side with respect to the coil holding member. The first coil and the second coil may be structured from one conducting wire.
