Abstract:
Provided is a master cylinder unit including a simulator pressure chamber which communicates with a pressure chamber of a master cylinder and moves a simulator piston by means of an introduced fluid pressure; a biasing chamber in which a biasing mechanism biasing the simulator piston against a fluid pressure introduced into the simulator pressure chamber is disposed; a first seal member which partitions a simulator supply chamber, the simulator supply chamber, and the simulator pressure chamber communicating with a master supply chamber; and a second seal member which partitions the simulator supply chamber and the biasing chamber and allows a brake fluid to flow from the simulator supply chamber to the biasing chamber when a pressure difference occurs between the simulator supply chamber and the biasing chamber.

Claim (Index 1):
A master cylinder unit comprising:\n a master cylinder that generates a fluid pressure in a pressure chamber inside a cylinder in accordance with an operation amount of a brake pedal; a reservoir that stores a brake fluid to be supplied to the pressure chamber; and a stroke simulator that communicates with the pressure chamber, generates a reaction force corresponding to an operation force of the brake pedal, and applies the reaction force to the brake pedal, wherein the master cylinder includes a master piston which moves inside the cylinder in response to an operation of the brake pedal, and a master supply chamber which is connected to the reservoir at all times and communicates with the pressure chamber when the brake pedal is not in operation, and wherein the stroke simulator has a simulator piston which moves inside a simulator cylinder, a simulator pressure chamber which communicates with the pressure chamber of the master cylinder on one end side of the simulator piston inside the simulator cylinder and moves the simulator piston by means of an introduced fluid pressure, a biasing chamber in which a biasing mechanism biasing the simulator piston against the introduced fluid pressure is disposed on the other end side of the simulator piston inside the simulator cylinder, a simulator supply chamber which is disposed between the simulator pressure chamber and the biasing chamber on an outer circumferential side of the simulator piston and communicates with the master supply chamber, a first seal member which partitions the simulator supply chamber and the simulator pressure chamber, and a second seal member which partitions the simulator supply chamber and the biasing chamber and allows the brake fluid to flow from the simulator supply chamber to the biasing chamber when a pressure difference occurs between the simulator supply chamber and the biasing chamber.
