スタシリンダピストンのバルブ。 The passage is formed along the axial direction of the master cylinder piston and is disposed at the forward movement side end of the master cylinder piston in the passage that communicates the oil reservoir and the oil discharge port with each other. In the valve of the master cylinder piston, which closes and opens the passage by contacting and separating from the side wall of the forward-moving side end by the forward and backward movements of the cylinder piston, the valve extends into the passage. A rod is provided at the distal end of the rod, and a first regulating portion is provided at the distal end of the rod and is slidably fitted into the inner wall of the passage, and a first regulating portion is provided at the proximal end of the rod so that the first regulating portion is provided at the distal end of the rod, and the first regulating portion is provided at the proximal end of the rod. A second regulating portion is provided that fits with the peripheral edge via a tapered surface, and the first and second regulating portions align the axial position of the valve with the axis of the passage when the valve is closed. A master cylinder piston valve characterized by:
