Abstract
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.
