To provide a pneumatic booster improving assembling efficiency.
A bracket 55 for supporting a pressure introduction pipe 45 inserted into a front shell 1 via a seal member 46 includes a U-shaped support part 57 on the other end side. The U-shaped support part 57 is constituted of a guide part 64 having a groove part 63 into which a base end part of a second pipe part 51 of the pressure introduction pipe 45 is inserted, a first abutting part 65 which extends in parallel with the guide part 64, abuts on peripheral surfaces of a large diameter pipe part 52b and a projecting part 52c of a connection pipe part 52 on an opposite side of a distal end part of the second pipe part 51 and supports force acting from the distal end part of the second pipe part 51 toward the peripheral surfaces, and a connecting part 66 for connecting the first abutting part 65 and the guide part 64. A negative pressure supply hose to supply engine negative pressure can be smoothly connected to the distal end part of the second pipe part 51 by the first abutting part 65 to improve the assembling efficiency.
