It has the above-mentioned 2nd crevice on the outer surface, and the 1st crevice and the 2nd crevice incline so that it may become deeper toward the opening part side. With this configuration, it is possible to reduce the step difference at the edge of the opening and eliminate the step difference at the end of the inclined surface on the opposite side of the opening. As a result, the electric wires connected to the first land and the second land are wired from the opening to the outside of the support body through the inclined surfaces of the first recess and the second recess, so that the wire is prevented from being broken by a step. can do.

Further, in the actuator disclosed in the present specification, the first recess is narrower than the first land, and the second recess is narrower than the second land. According to this structure, the electric wire is prevented from rattling in the first concave portion and the second concave portion, so that workability in connecting the electric wire to the land is improved.

Further, in the actuator disclosed in the present specification, the first recess and the second recess are formed in a U-shaped cross section. According to this configuration, the electric wires connected to the first land and the second land can be stably held in the first recess and the second recess, respectively, and workability when connecting the electric wire to the land is further improved. To do.

Further, in the actuator disclosed in the present specification, the side plate portions are adjacent to the first land and the second land in a direction in which the first land and the second land are arranged, and the first recesses and the first recess are provided at intervals in the direction. It has a second recess.

In addition, in the actuator disclosed in the present specification, the side plate portion includes the first recess and the second recess that are integrally provided adjacent to each other in the alignment direction of the first land and the second land.

Further, in the actuator disclosed in the present specification, the side plate portion includes the first recess and the second recess provided on opposite sides of the first land and the second land, respectively.

The haptic device disclosed in the present specification includes a movable body, a support, and at least one of elasticity and viscoelasticity, and the movable body and the support are provided at a position where the movable body and the support face each other. A connecting body arranged so as to be in contact with both of the bodies, an air-core coil provided on one member of the movable body and the supporting body, and facing the coil on at least one side in the first direction. So that it has one or more permanent magnets provided on the other side member of the movable body and the support, and the movable body is moved in a second direction intersecting the first direction with respect to the support. A magnetic drive circuit for vibrating and a power feeding board having first and second lands electrically connected to the coil, wherein the support body is orthogonal to the first direction and the second direction. The power supply board is held by the support so that the first land and the second land are exposed through the opening, and the side plate has an opening provided in three directions. The side plate portion extends toward the first land and reaches one or more first recesses that reach the edge of the opening, and the side plate portion extends toward the second land and one or more first recesses that reach the edge of the opening. Two concave portions are provided on the outer surface, and the first concave portion and the second concave portion are inclined so as to become deeper toward the opening portion side.
