特徴とするマスタシリンダ。 Inside the cylinder body, there is a pair of sealing cups that contact the outer peripheral surfaces of the primary piston and the secondary piston, and when these cups are fixed to the cylinder body, a first pressurizing chamber is formed between both pistons. A sleeve is provided in the inserted state, and the sleeve is provided with a through hole that communicates between the outlet port and the first pressurizing chamber, and the through hole is opened by normal reciprocating movement of the secondary piston. The secondary piston is partially opened and closed, and the opening in the normal retracted position of the secondary piston forms a constricted portion with increased flow resistance between the outlet port and the first pressurizing chamber. master cylinder.
