Claims

[Scope of utility model registration request]

a main body having an internal space; a movable body that is movably inserted into the internal space to partition a low pressure chamber on one side and a high pressure chamber on the other side; an input member that fits into an inner hole of the hub portion from the other side; an output member that extends from one side of the movable body to the outside through the main body; a valve device that is provided and controls the low pressure chamber and the high pressure chamber to generate a pressure difference that biases the movable body to one side in response to an input from the input member, the valve device:
In the pneumatic booster, the pneumatic booster has a valve plunger attached to an end of the input member, and a valve member biased to seat toward a valve seat formed on the other side of the valve plunger. A pneumatic booster comprising a valve member provided with a recess facing the valve seat.
