とを特徴とする第(2)項記載の負圧ブースタ。[Claims for Utility Model Registration] (1) A booster piston 4 that is spring-biased in the backward direction is housed in the booster shell 1, and a negative pressure is provided in front of the booster piston 4, which is constantly connected to a negative pressure source. A chamber 5 and an operating chamber 6 on the rear side of the booster piston 4 are formed, and a stopper 42 extending radially inward at the rear end of the support cylinder 17 provided at the rear of the booster shell 1 is configured to introduce atmospheric air at its inner edge. An input rod 24, which is provided to form a port 43 and is connected to the brake pedal 22 via a clevis 23 and inserted through the atmosphere inlet 43, is connected to the booster piston 4 so as to be freely forward and backward while allowing its rocking motion. A control valve 20 is provided between the input rod 24 and the booster piston 4 and is capable of switching the state of communication of the working chamber 6 with the negative pressure chamber 5 and the atmosphere. , the input rod 2
In the negative pressure booster, an abutting member 41 that can abut on the inner surface of the stopper 42 is attached to restrict the retracting limit position of the clevis 4. The contact member 4 is formed in a rectangular shape that is long in the swinging direction.
Reference numeral 1 denotes a negative pressure booster characterized in that it is formed in a circular shape with an outer diameter shorter than the longitudinal length of the air inlet 43. (2) At the rear of the booster shell 1, there is a cylindrical portion 1 having a regulating collar 13 extending radially inward at the rear end.
0 protrudes rearward and is integrally provided, and guides the forward and backward movement of the booster piston 4.
A sealing member 12 for sealing between the atmosphere inlet 43 and the working chamber 6 is interposed between the cylindrical portion 10 and the booster piston 4 while being prevented from moving rearward by the regulating collar 13, and is interposed between the cylindrical portion 10 and the booster piston 4.
7 is a booster shell 1 surrounding the cylindrical portion 10.
The negative pressure booster according to item (1), characterized in that it is coupled to. (3) The support tube 17 is integrally provided with the reinforcing plate 16 that is in close contact with the outer surface of the rear part of the booster shell 1, and extends through the rear part of the booster shell 1 and the reinforcing plate 16 in order to connect the rear part of the booster shell 1 to the support body 48. The negative pressure booster according to item (2), wherein the rod-shaped connecting member 2 and the reinforcing plate 16 are integrally caulked to the rear part of the booster shell 1.
