Claims

[Scope of utility model registration request]

A rack is connected to the movable core of a single-acting solenoid that urges the movable core in either the forward direction or the backward direction by the elasticity of a spring and attracts the movable core in the other direction by excitation. The engaging pinion is connected to a rotating body via a clutch that transmits rotation in only one direction, the rotating body is connected to an orifice area control shaft of a shock absorber, and a rotary switch is provided between the rotating body and the case. and the rotary switch is connected to the excitation circuit of the solenoid, and the rotary switch is configured to open and self-shut off the excitation circuit at the operating end position of the movable iron core which is attracted and operated by the excitation of the solenoid. An electromagnetic drive device for controlling the orifice area of a shock absorber.
