摘要： A vehicle braking apparatus includes: a control piston configured to operate so that a reaction force based on the fluid pressure of the boosted fluid pressure application chamber is balanced with a braking operation input from the brake operation member; an elastic member including: a first face adapted to contact with a simulator piston connected to the brake operation member and slidably accommodated in the control piston; and a second face; a sliding member adapted to contact with the second face, the sliding member being accommodated in the control piston; a spring disposed between the sliding member and the control piston; and an odd-shaped portion disposed at least one of the first and second faces of the elastic member, the odd-shaped portion configured to increase a contacting area of the elastic member and at least one of the simulator piston and the sliding member.

摘要： A fluid pressure booster for a braking device includes a control piston on which an input brake operation acts in an advancing direction, and a reaction force based on fluid pressure of a booster fluid pressure generation chamber acts in a retracting direction. A pressure increasing valve is provided between a valve chamber communicating with a fluid pressure generation source and the booster fluid pressure generation chamber. A pressure reducing valve is provided between a release chamber communicating with a reservoir and the booster fluid pressure generation chamber. At least one contraction portion is formed between an outer periphery of a front portion of the pressing rod and an inner periphery of a front portion of a valve seat member.

摘要： A vehicle brake device includes an elastic body being formed such that a circulation of an operation fluid is permitted from a front end to a rear end of the elastic body until a filling rate of the elastic body reaches a predetermined value in a filling area where deformation of the elastic body is stopped by restraint of a control piston in a state where a forward stroke of the control piston is less than at least a predetermined stroke, but the circulation of the operation fluid is stopped when the filling rate reaches the predetermined value or more.
