液圧可動体に前記液圧室と前記補給室とを連絡し
て形成した通路を当該液圧可動体と前記軸部材と
の相対的な移動に応じて開閉する弁体とを備えた
ブレーキブースタにおいて、前記弁体を前記液圧
可動体に向つて付勢する所定の予負荷をもつ弾性
体を設けたブレーキブースタ。 a main body having a relatively small diameter cylinder hole and a relatively large diameter hole formed coaxially with the cylinder hole;
a pneumatic movable body that is movably inserted into the hole and defines a pressure-free chamber on the cylinder hole side and a pressure chamber to which compressed air is supplied on the opposite side; A shaft member whose end is fitted into the cylinder hole, a supply chamber which is slidably fitted into the cylinder hole and is connected to the hydraulic fluid reservoir on the hole side, and a hydraulic pressure that is connected to the brake cylinder on the opposite side. A hydraulic movable body that partitions a chamber, a coupling means that connects the hydraulic movable body and the shaft member so that they can move relative to each other within a predetermined range, and between the hydraulic movable body and the shaft member. The hydraulic movable body is disposed so as to be movable integrally with the shaft member, and a passage formed by communicating the hydraulic chamber and the supply chamber is provided in the hydraulic movable body relative to the shaft member. What is claimed is: 1. A brake booster comprising a valve body that opens and closes in response to movement, the brake booster comprising an elastic body having a predetermined preload that urges the valve body toward the hydraulic movable body.
