摘要： An actuator causes vibration of a movable body by a magnetic drive mechanism. The movable body includes: a support shaft having an outer circumferential surface fixed with a magnet; a cup-shaped first magnetic member fixed to an end surface of the magnet in an axial direction; and a second magnetic member fixed to an opposite side of an end plate of the first magnetic member from the side of the magnet. A weight adjustment section in the second magnetic member is a through hole. An outer shape of the second magnetic member is not reduced in size. A bent section of the first magnetic member overlaps an outer circumferential end of the second magnetic member. The weight adjustment section is provided on an inner circumferential side of an outer circumferential surface of the magnet. A magnetic member deficient portion is provided to avoid a portion with high magnetic flux density.

摘要： A solenoid assembly includes a solenoid having a coil that defines a passageway and a plunger movable within the passageway from a retracted position to an extended position. The plunger extends along an axis between a first plunger end and an opposite second plunger end. A frame holds the solenoid and has a first opening through which the first plunger end extends when the plunger is in the retracted position and a second opening through second end of the plunger extends when the plunger is in the extended position. When the plunger is in the extended position the first plunger end retracts into the frame via the first opening.
