摘要： An actuator has: an affixed section having a coil; a first mobile section that is elastically held and disposed so as to allow movement in the axial direction inside one end of the coil, and has a first magnet magnetized in the axial direction of the coil and disposed on one end in the axial direction; and a second mobile section that is elastically held and disposed so as to allow movement in the axial direction inside another end of the coil, and has a second magnet magnetized in the axial direction and disposed on the other end in the axial direction. The first and second magnets are disposed such that identical magnetic poles are in the same direction in the axial direction, and the first and second mobile sections move in opposite directions along the same axis when a current is applied to the coil.

摘要： An oscillatory actuator has: a fixed body that has a planar part and a flat coil disposed on the planar part; and a movable body that has a magnet facing the coil and oscillates in a reciprocating manner in one direction relative to the fixed body above the planar part via cooperation between the coil and the magnet. The fixed body has a pair of linear bearings that are respectively disposed along both side surfaces extending in said one direction of the movable body and are equipped with balls capable of rolling and coming into contact with the respective side surfaces. The movable body is supported via the balls of the linear bearings so as to be able to oscillate in said one direction.

摘要： The purpose of the present invention is to provide a vibratory actuator the size of which can be reduced and which effectively produces vibrations felt by a user. The vibratory actuator has: a stationary body which has a curved surface section curved in a concave shape to be placed along the skin; and a movable body which is disposed on the curved surface section so as to be able to move with respect to the stationary body in a reciprocating manner along the curved surface section, thereby imparting a vibratory stimulus caused by the reciprocating motion to mechanoreceptors in the skin tissue via the curved surface section.

摘要： The purpose of the present invention is to provide an actuator that has a simple configuration and can stably achieve high output without the occurrence of magnetic saturation. This actuator has: a movable body provided with a cylindrical magnet section having alternately N-pole faces and S-pole faces on the peripheral surface surrounding a rotation shaft; and a fixed body provided with, pole tooth surfaces of the same number as the N-pole faces and the S-pole faces, and a coil that excites the pole tooth sections. The movable body has as a turning reference position a position at which the center of the pole tooth surfaces in the circumferential direction and the switching position of the pole faces of the magnet section face each other, and is held to the fixed body so as to be turnable back and forth around the rotation shaft in the circumferential direction.
