摘要： An electromagnetic actuator including: a stator; a mover attached displaceable in relation to the stator; a plurality of plate springs elastically coupling the stator and the mover; and a coil member attached to one of the stator and the mover. Each of the plate springs includes an outer circumference attachment part and a center attachment part respectively attached to one and another of the stator and the mover. A plurality of spiral-shaped connection arm parts are provided at equal intervals in a circumferential direction radially between the outer circumference attachment part and the center attachment part so as to extend in a radial direction while being inclined in the circumferential direction. The plate springs overlap in a thickness direction and all of the plate springs are mutually formed with a same material and in a same shape.

摘要： A vibration-damping electromagnetic actuator including: a tubular stator including at least one coil member having a coil and an outer yoke attached to the coil; a mover including a permanent magnet and at least one inner yoke superposed in an axial direction of the stator, the mover being inserted into the tubular stator as axially displaceable relative to the stator through energization to the coil; and an inner tubular part provided at the outer yoke being superposed on an inner peripheral face of the coil to have a magnetic gap, wherein the at least one inner yoke has a thick part at an outer peripheral part thereof, and a lightening part at an inner peripheral part thereof so that an axial dimension of the inner yoke is smaller in a formation part of the lightening part than in the thick part.

摘要： A vibration-damping electromagnetic actuator including: a stator; a movable member displaceable relative to the stator, and being disposed within or about it; a coil member with a coil generating a magnetic field through energization, which is disposed at one of the stator and the movable member; an armature displaceable relative to the coil member by an effect of the magnetic field generated by the coil, which is disposed at the other one of the stator and the movable member; a tubular guide sleeve disposed between the stator and the movable member so that the movable member is slidable along the guide sleeve; and an elastic support body fixed to the guide sleeve being clamped by the stator at a portion of the elastic support body apart from the guide sleeve so that the guide sleeve is elastically supported by the stator.

摘要： A vibration-damping electromagnetic actuator including: a tubular stator; a movable member displaceable relative to the stator in an axial direction, and being inserted in the stator; a housing including a tubular peripheral wall and being attached to the stator; a support rubber elastic body elastically connecting the movable member to the housing; and a coil member and an armature displaceable relative to the coil member disposed at one and the other of the stator and the movable member respectively. The stator is arranged in an inner periphery of the peripheral wall, and a gap is provided between the peripheral wall and the stator in an axis-perpendicular direction. The stator is attached to the housing in a state aligned with the movable member by means of displacement of the stator relative to the housing in the axis-perpendicular direction.
