Abstract
PURPOSE: To improve sealing efficiency between a fixing cylindrical portion and a tie rod by fittingly engaging the fixing cylindrical portion provided at the front end of an expansion boot which plunges into the boot with a fixing groove on the tie rod; said boot is covering a reaction force transmission rod of the output side.
CONSTITUTION: Fixing cylindrical portion 26a is equipped at the front end of expansion boot 26 covering tie rod 14 to plunge into boot 26a. Portion 26a is fittingly engaged with fixing groove 14c on a circumference of tie rod 14. When booster piston 2 forwards and an atomosphere is introduced into working chamber B, the atomosphere works to force circumference of fixing cylindrical portion 26a onto in fixing groove 14c of tie rod 14 and as the result, fixing cylindrical portion 26a contacts fixing goorve 14c closely to permit any clearance between them.
