、マスタシリンダ及び負圧ブースタの組立体。 The rear end of the cylinder body of the master cylinder is attached to the front face of the booster shell of the negative pressure booster, and the rod part of the piston that slides into the cylinder hole of the cylinder body is thrust into the booster shell and connected to the output rod inside the booster shell. A sealing member that is in close contact with the outer circumferential surface of the rod portion is attached to a bearing that is connected to the cylinder body and that is fitted into the cylinder body and slidably supports the rod portion, and that is provided so as to protrude from the rear end surface of the cylinder body. a positioning cylinder part surrounding the rod part;
A rear seal member that is in close contact with the outer peripheral surface of the rod portion is interposed between the end wall of a positioning recess formed in the front surface of the booster shell in order to fit the positioning cylinder portion into the cylinder body and the booster shell. In an assembly of a master cylinder and a negative pressure booster, the hollow part of the positioning cylinder part is communicated with a groove open to the atmosphere formed in the lower part between the opposing surfaces of the master cylinder and the negative pressure booster. An annular hook portion formed on one side of the outer periphery of the rear seal member is attached to the annular groove, and an annular passage communicating with the groove is left on one side of the annular hook portion, and the annular passage and An assembly of a master cylinder and a negative pressure booster, characterized in that a through hole communicating between the hollow parts is bored in the positioning cylinder part.
