PURPOSE: To widen degree of freedom in the implanting pitch of stud bolts for mounting and enhance the easiness in mounting works to a vehicle. CONSTITUTION: A valve body 13 is stretched from a power piston 8 set in a housing 3, and the tail 13a of the valve body 13 is inserted through a rear shell 2 having a cylindrical part 40, which is formed protrusively inward of the housing 3 from the back surface of the rear shell 2. A seal member 14 is installed on the inside of an inner flange 41 formed at the protrusive end of the cylindrical part 40, and a stop key 33 installed on the valve body 13 to restrict the return position of the power piston 8 is contacted with the protrusive end of the cylindrical part 40. A flat part 2b having a large area is secured on the back surface of the rear shell 2 around the cylindrical part 40, and stud bolts 35 for mounting to a vehicle are implanted in this flat part 2b. |
