成されたマスタシリンダ装置。 It has a small-diameter pressure chamber and a large-diameter annular pressure chamber whose pressure increases when the stepped piston operates, and a pressure limiting valve which limits the pressure increase in the large-diameter annular pressure chamber to a relatively low predetermined pressure, when the stepped piston operates. In the master cylinder device configured such that the pressure fluid in the large diameter annular pressure chamber flows into the small diameter pressure chamber via a check valve mechanism and is discharged from the outlet together with the pressure fluid in the small diameter pressure chamber, the stepped piston has a large diameter. A diameter portion and a small diameter portion are slidably fitted into the cylindrical portion of the booster housing and the master cylinder body, respectively, and one end thereof is sealingly fixed within the cylindrical portion near the large diameter portion of the stepped piston. A master cylinder device in which the large-diameter annular pressure chamber is formed by a bellows whose other end is hermetically sandwiched and fixed between the cylindrical portion and the master cylinder body.
