Claims

[Claims for Utility Model Registration] A shaft hole 41 is provided in the end wall of the booster shell 1, and the shaft hole 41 is provided in the reinforcing plate 30 superimposed on the inner surface of the end wall.
A large diameter hole 42 surrounding the shaft hole 4 is formed respectively, and the shaft hole 4
Head 3 of connecting bolt 33 with shaft 36 inserted into 1
5 is composed of a small diameter portion 35a that fits into the large diameter hole 42 and a large diameter portion 35b that abuts the inner surface of the reinforcing plate 30, and is attached to the booster shell 1 by screwing the nut 34 onto the shaft portion 36. In the negative pressure booster to which the other member 32 is fixed, an annular groove 38 surrounding the shaft hole 41 is formed on the end surface of the small diameter portion 35a of the head 35, and an annular groove 38 is formed on the inner surface of the booster shell 1 in the annular groove 38. A negative pressure booster characterized by being equipped with a sealing member 39 that is in close contact with the other.
