Abstract:
Provided is a master cylinder unit including a communication path that causes a master cylinder and a stroke simulator to communicate with each other. The stroke simulator includes a bottomed tube-shaped simulator piston and a simulator cylinder in which a simulator piston slides. The simulator piston is such that a bottom portion of the simulator cylinder and an opening portion of the simulator piston face each other. The communication path is open over an outer circumferential portion and an inner circumferential portion of the opening portion of the simulator piston, is connected to the bottom portion of the simulator cylinder, and is provided such that the communication path extends upward in a vertical direction from the bottom portion of the simulator cylinder as approaching to a pressure chamber.

Claim (Index 1):
A master cylinder unit comprising:\n a master cylinder that causes a fluid pressure to be generated in a pressure chamber inside a cylinder in accordance with an operation amount of a brake pedal; a reservoir that supplies a brake fluid to the pressure chamber; a stroke simulator that communicates with the pressure chamber and applies a reaction force corresponding to an operation force of the brake pedal to the brake pedal; and a communication path that causes the master cylinder and the stroke simulator to communicate with each other, wherein the stroke simulator includes a bottomed tube-shaped simulator piston and a simulator cylinder in which the simulator piston slides, wherein the simulator piston is disposed such that a bottom portion of the simulator cylinder and an opening portion of the simulator piston face each other, and wherein the communication path is open over an outer circumferential portion and an inner circumferential portion of the opening portion of the simulator piston, is connected to the bottom portion of the simulator cylinder, and is provided such that the communication path extends upward in a vertical direction from the bottom portion of the simulator cylinder as approaching to the pressure chamber.
