ABSTRACT:
A recess and another recess having an enlarged diameter with respect to the recess are defined in a main body, wherein a valve guide body is inserted into the recess. Projections of the valve guide body engage inside grooves defined in a wall portion constituting the recess, and second projections of a cover member engage with first projections formed on a wall constituting the other recess, stopping the cover member from falling out. A pressure of a pressurized fluid which is imposed on the valve guide body is supported by the cover member. As a result, there is no concern of damage to the valve guide body, and moreover, there is no concern of unexpected dislocation of the valve guide body.
