For this reason, as shown in Japanese Patent Application Laid-Open No. 53-38866, a rigid cylinder reinforcing member with open ends is integrally molded with a lightweight material such as synthetic resin in order to reduce the weight. Since the pressure fluid discharge port is coaxially formed in the cylinder reinforcing member, the overall length of the cylinder becomes long, making it impossible to downsize the cylinder. Furthermore, since the cylinder reinforcing member is cylindrical, it has the disadvantage that it tends to peel off from the integrally molded synthetic resin.

As described above, in this invention, the discharge port reinforcing member is joined to the upper edge of the end opposite to the opening of the rigid cylinder reinforcing member with an opening at one end, and is integrally molded with synthetic resin. Positioning of the resin and the cylinder reinforcing member is easy, and the master cylinder can be made smaller and lighter. Moreover, since the cylinder reinforcing member is cylindrical, the synthetic resin molded into the cylinder reinforcing member is regulated by the discharge port reinforcing member even if a rotational force or a force moving in the cylinder axial direction is exerted, so that no peeling phenomenon occurs and the resin is securely molded. Fixed. Since this discharge port reinforcing member is joined to the upper edge of the cylinder reinforcing member, even if air may accumulate in the cylinder, the air removal operation can be performed easily and reliably. Furthermore, since the discharge port reinforcing member is disposed between the cylinder reinforcing member and the reservoir, the overall length of the cylinder can be particularly shortened.
