Abstract
By providing a mountain-shaped mountain portion () protruded from a surface of a plunger () facing a valve seat to the inside of a rubber member (), a dimensional change amount of a valve seat abutting portion () in an opening and closing direction decreases, and thus it is possible to suppress change in characteristic. Also, it is possible to secure a rubber deformation amount sufficient for absorbing impact when the valve seat abutting portion () collides with the valve seat, thereby suppressing an operation sound.
