Abstract
A vehicle braking device includes a stroke simulator provided between a control piston of a fluid pressure booster and a brake operation member, wherein the control piston has an inner peripheral surface partially including a tapered surface with a decreasing diameter toward the front. The stroke simulator includes an input member housed in the control piston slidably in an axial direction backward of the tapered surface and connected to the brake operation member, and an elastic body interposed between the input member and the control piston and housed in the control piston. The elastic body has a cylindrical shape so as to be elastically deformed according to an action of an axial compressive force along with an advancing operation of the input member, and prevented from being deformed sequentially from the front by restraint with the tapered surface according to an increase in the axial compressive force. This provides a nonlinear characteristic in a relationship between a brake operation stroke and an operation load, and efficiently provides a hysteresis characteristic.
