ブースタ。The inside of the housing is divided into a front chamber and a rear chamber by a diaphragm and a power piston, the front chamber is communicated with a vacuum source, and a rear chamber is provided in a hollow shaft part provided on the power piston so as to protrude toward the rear side of the housing. A vacuum booster is provided with a control valve mechanism for selectively communicating the front chamber with the atmosphere, a bushing rod for operating the control valve mechanism, and a spring that biases the bushing rod rearward. A vacuum booster comprising a spring retainer disposed on the bush rod to receive the spring retainer, the outer peripheral part of which is formed into a dish shape extending forward, and the outer diameter of the spring retainer being made as large as possible.
