ABSTRACT:
According to the plunger-typed master cylinder of the invention, because deformation of seal cups fitted in the hydraulic pressure chambers with the pistons (primary piston and floating piston) inserted is minimized, that is, the deformation of the inner flange being in contact with pistons does not substantially affect the outer flange being in contact with hydraulic pressure chambers when the master cylinder is in operation, it is possible to prevent deterioration in the performance of passing or stopping oil due to the deformation of seal cups and durability.
