An object of the present invention is to provide a stroke simulator in which the piston operates smoothly without being inhibited from displacement thereof by the negative pressure generated in the closed space, even if the piston is configured to be displaced so as to close the space in which the elastic member is housed, and to elastically deform the elastic member. A stroke simulator, in which a simulator piston (2a), which is displaced within a cylinder portion (200) by an operation of a brake operating element by a driver, presses a first return spring (2b), which is housed in a bottomed cylindrical portion (224d), from an opening portion (224d2) side of the cylindrical portion (224d), to cause the first return spring (2b) to be elastically deform, and to generate a brake reaction force. When the opening portion (224d2) is closed by the simulator piston (2a), a brake fluid filled in the cylinder portion (200) is taken into the inside of the cylindrical portion (224d) via a flow path (224d1) leading to the inside of the cylindrical portion (224d) from a second cylinder (202). |
