Braking stroke simulator

The present invention is directed to a braking stroke simulator for use in a brake system, which comprises a simulator piston moved in response to operation of a manually operated braking member, and an elastic element for providing a stroke to the simulator piston in response to braking operation force applied to the manually operated braking member, wherein restoring amount of the elastic element is restricted to set an initial load to be applied thereto. The elastic element includes a first elastic member made of rubber, and a second elastic member made of a helical spring, which is disposed in series with the first elastic member. The initial load applied to the first elastic member and the initial load applied to the second elastic member are set to be substantially equal to each other.
