Abstract

An object of the present invention is to secure a gap between a component on a suction valve side and a component on an anchor side when a valve is closed, regardless of an integration tolerance of a plurality of components, and to be able to reliably close the valve. In an electromagnetic valve mechanismincluding an anchor assemblyand a magnetic corebetween which a magnetic attraction force acts, and a suction valveconfigured to be able to come into and out of contact with the anchor assembly, the anchor assemblyincludes a first anchor assembly componenthaving a facing surfacethat faces the magnetic core, a second anchor assembly componentconfigured integrally with the first anchor assembly component, and a press-fitting portionthat fixes the first anchor assembly componentand the second anchor assembly component. A press-fitting length Lof the press-fitting portionis set to a length at which the second anchor assembly componentand the suction valveare separated from each other in a state where the suction valveis closed.
