PURPOSE:To simplify a structure for reducing play, by interposing a stop device capable of engaging these engaging parts in space between an engaging part installed in the side of a rear end part of a hub member and another engaging part installed in the side of an input shaft. CONSTITUTION:A first engaging part 37 is installed at the side of a rear end part of a hub member 9 and also a second engaging part 36 is installed at the side of an input shaft 19. And, a stop device 40 capable of engaging these engaging parts 36 and 37 is interposed between both these engaging parts 36 and 37. This stop device 40 makes the input shaft 19 go forward as far as the specified value to the hub member 9. And a booster 1, a master cylinder and a brake pedal are attached to an actual car, and at the point that each adjustment is over, the stop device 40 is turned round with a grip part 42 thereby engagement between the stop device 40 and each of engaging parts 36 and 37 is released free. But the input shaft 19 and the hub member 9 both are kept at that position by means of a pedal stopper or the like. At this position, a valve member 24 comes into a state of being seated at both valve seats 22 and 23, thus there is no play. |
