PROBLEM TO BE SOLVED: To enable a stroke simulator to be allocated in a cabin.SOLUTION: A stroke simulator 3 includes a cylindrical cylinder 31 coupled to a brake pedal 1 by a pin 4, a shaft 32 that moves in an unified fashion with a piston 21 of a master cylinder 2, and a simulator spring 33 to generate reaction force in a predetermined stroke range. The shaft 32 is configured in a manner being capable of relative movement against the brake pedal 1 and the cylinder 31 by the pin 4 being inserted into a long hole 327. In a region where a pushing down amount of the brake pedal 1 is small, the shaft 32 does not move. When the brake pedal 1 is operated up to the intermediate position, a cylinder second cylindrical part 312 and the opposing face of the spring guide part 322 contact with each other. When the brake pedal 1 is pushed down further, the cylinder 31 and the shaft 32 move in an unified manner, and the master cylinder 2 generates a brake fluid pressure in conjunction with the brake pedal 1.SELECTED DRAWING: Figure 1 |
