Document Type and Number:
Japanese Patent JPH11111521
Kind Code:
A
Abstract:
To provide an electromagnetic actuator which produces lower noise, when the collision energy is the same.
An electromagnetic actuator is provided with at least one electromagnet equipped with a coil and yokes, having at least one magnetic pole surfaces and an armature coupled with an operating member, and the armature is movably guided to the magnetic pole surface of the electromagnet against the force of a return spring, can be brought into contact with the magnetic pole surface and operates the operating member. At least the partial extent of at least either an armature 3 or yokes 4.1 and 5.1 is formed so that the armature 3 or yokes 4.1 and 5.1 is deformed elastically in the moving direction of the armature 3.
