<P>PROBLEM TO BE SOLVED: To obtain desired hysteresis by preventing an operation fluid from being locked in the state that the operation fluid is interposed between an elastic body and a control piston in the control piston introduced with it in a brake device for a vehicle provided with a stroke simulator provided between the control piston of a hydraulic booster and a brake operation member. <P>SOLUTION: In the brake device for the vehicle, an elastic body 199 is formed such that it is successively abutted on an inner surface of the control piston 66 by advancement of an input member 194 according to brake operation of a brake operation member and is stored in the control piston 66. A gap between the elastic body 199 and the control piston 66 is communicated with a reservoir at an advancement stroke of the control piston until the operation fluid is sealed in the control piston 66. <P>COPYRIGHT: (C)2007,JPO&INPIT |
