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 mechanism 300 including an anchor assembly 36 and a magnetic core 33 between which a magnetic attraction force acts, and a suction valve 30 configured to be able to come into and out of contact with the anchor assembly 36, the anchor assembly 36 includes a first anchor assembly component 36a having a facing surface 36ab that faces the magnetic core 33, a second anchor assembly component 36b configured integrally with the first anchor assembly component 36a, and a press-fitting portion 36c that fixes the first anchor assembly component 36a and the second anchor assembly component 36b. A press-fitting length L1 of the press-fitting portion 36c is set to a length at which the second anchor assembly component 36b and the suction valve 30 are separated from each other in a state where the suction valve 30 is closed.
