In a cup seal, the hydraulic pressure in a first hydraulic chamber (6) causes a first seal portion (21e) of an outer lip portion (21c) to closely contact to a bottom wall (20a) of a recessed portion (20) and causes a second seal portion (21f) of a base portion (21a) to closely contact to a rear surface (20b) of the recessed portion (20). A double seal due to the first and second seal portions (21e) and (21f) reliably prevents the leakage of a brake fluid from the first hydraulic chamber (6).
