Title:

ELECTROMAGNETIC SOLENOID

Document Type and Number:

WIPO Patent Application WO/2016/132467

Kind Code:

A1

Abstract:

Provided is an electromagnetic solenoid that is highly versatile and enables a decrease in resonance and the like while achieving size reduction, and that also enables a decrease in the number of components and the amount of affixing operation and the like. A shock absorbing means 31 comprises: a bearing member 17 provided in an accommodating portion 15b of a movable yoke 15 in an axially movable manner and including a protruding portion 17b protruding from a rear end portion of the movable yoke 15, and a spring 32 disposed between the bearing member 17 and a plunger 20 to bias the bearing member 17 against a bearing surface 18. Accordingly, high versatility and size reduction can be achieved. Further, because the movable yoke 15 is provided with the shock absorbing means 31, vibration (resonance) can be decreased. In addition, the need for affixing a regulating portion in the form of a separate component to an affixing portion by swaging , as according to conventional art, can be eliminated, whereby an increase in the number of components or the amount of affixing operation can be prevented, resulting in lower cost.
