ことを特徴とするマスタシリンダ。[Scope of claim for utility model registration] The cylinder body to which the reservoir tank is connected,
A piston that is slidably fitted into the cylinder body, a fluid level detection sensor that detects the level of brake fluid stored in the reservoir tank, and a detection result of the fluid level detection sensor that outputs the detection result to the outside. A master cylinder is constructed of a socket that can be connected to an external terminal, and sends out brake fluid by the movement of the piston, and the piston is provided with a magnet, and the cylinder body is provided with a reed switch that closes the contact by magnetic force. The master cylinder is characterized in that the reed switch is disposed in a position close to the magnet that is displaced due to overstroke movement of the piston due to failure of the brake system, and is connected to the socket portion. .
