PURPOSE:To secure a bolt antislip device and improve a working property of assembling, by forming a bolt antislip part proximately opposed to the head of a bolt clamping each member of a valve body, in a key member which prevents a valve plunger from slipping from the valve body. CONSTITUTION:A body proper 6a of a valve body 6 and a disclike hub 66 are solidly coupled together by a bolt 40 and a nut 41 being piercing through in an axial direction. And, a key member 35 preventing a valve plunger 11 from slipping from the valve body 6 is projected out of a valve body proper 6a. At this projecting part, a bolt antislip part 35 being proximately opposed to a head part 40a of the said bolt 40 is formed. At this time, a maximum distance (a) between the key member 35 to move in its axial direction and the head part 40a of the bolt 40 is to be set so as to become smaller than the axial size (b) of a portion where the head part 40a of the bolt 40 engages a groovelike engaging part 42 of the valve body proper 6a. With this constitution, an antislip technique for the bolt 40 comes yet surer in time of assembling work, thus a working property is improved. |
