Abstract
Reaction force from a reaction member is divided and transmitted to a front shaft portion of a plunger via abutment member and to a flange portion of the plunger via a spring unit. The spring unit includes a tubular first holding member assembled to the front shaft portion of the plunger and being engageable, at its front end portion, with the reaction member, a second holding ember assembled to a rear end portion of the first holding member and having a rear end portion which extends rearward from the first holding member for engagement with the flange portion, and Belleville springs held between the first and second holding members. When the reaction force transmitted from the reaction member to the first holding member exceeds the load of the springs, the first holding member moves while compressing the springs and engages with a stepped portion of a valve body.
