Claims

[Claims for Utility Model Registration] 1. A rotary lever that pushes a piston inserted into the cylinder body is provided with a stopper that restricts the backward limit when not in operation, and a boss protruding from the cylinder body is provided with a stopper that controls the retraction limit when the piston is not activated. In a vehicle hydraulic master cylinder fitted with a connector, the reservoir connector is formed of a buffer material such as synthetic resin, and the connector is provided with a stopper that supports a stopper of the rotary lever that is biased in a non-operating direction. A hydraulic master cylinder for a vehicle characterized by having a contact portion. 2. A stopper is provided on the rotary lever that pushes the piston inserted in the cylinder body to restrict the backward limit when not in operation, and the cylinder body is provided with a brake lamp switch that is activated by contact with the stopper. In the vehicle hydraulic master cylinder provided, the switch body of the brake light switch is formed of a buffer material such as synthetic resin, and the switch body supports a stopper of the rotary lever that is biased in a non-operating direction. A vehicle hydraulic master cylinder characterized by:
