Claims

[Claims for Utility Model Registration] 1. A piston for generating hydraulic pressure is inserted into a cylinder hole formed in a cylinder body, the piston is pushed by a pushing member, and a stopper is operated as the piston is pushed. In a brake hydraulic master cylinder in which a switch case housing a plump switch is attached to a cylinder body, the switch case is fitted with a housing portion for the stop lamp switch, and is engaged with the piston or the pushing member and extends along the cylinder body. an actuator that moves with the cylinder to operate the stop lamp switch; an actuator that allows the actuator to move; and a stopper projection that penetrates the cylinder body and projects to the inner periphery of the cylinder hole to restrict the retraction limit of the piston. A hydraulic master cylinder for brakes, characterized in that it is provided with. 2. A piston for generating hydraulic pressure is inserted into a cylinder hole formed in a cylinder body, and the piston is pushed by a pushing member, and a switch case housing a stop lamp switch that operates as the piston is pushed is provided. In a brake hydraulic master cylinder attached to a cylinder body, the switch case has a housing portion for the stop lamp switch, and engages with the piston or pushing member to move along the cylinder body and operate the stop lamp switch. A hydraulic master cylinder for a brake, characterized in that it is provided with an actuator that operates, an operating chamber that allows movement of the actuator, and a connector that connects a reservoir that supplies hydraulic fluid into the cylinder hole. 3. A piston for generating hydraulic pressure is inserted into a cylinder hole formed in a cylinder body, and the piston is pushed by a pushing member, and a switch case housing a stop lamp switch that operates as the piston is pushed is provided. In a brake hydraulic master cylinder attached to a cylinder body, the switch case has a housing portion for the stop lamp switch, and engages with the piston or pushing member to move along the cylinder body and operate the stop lamp switch. An actuator that operates and an operating chamber that allows movement of the actuator are provided, and a groove for fitting a dust boot is formed on the outer periphery of the storage portion, and a groove for fitting a switch case is formed in the dust boot. A brake comprising: a fitting portion that fits into a side wall of a cylinder body; a cover portion that covers the storage portion and the actuator; and a fitting portion that fits the piston or the pushing member. Hydraulic master cylinder.
