Claims

[Scope of utility model registration request]

A control valve mechanism is built into the power piston, which is operated by a bushing rod that is linked to the pedal, and controls the pressure difference between the front and rear chambers of the power piston, and outputs the forward thrust generated in the power piston due to the pressure difference to the outside. a small diameter hole in the power piston that accommodates a front end of a valve plunger connected to a front end of the bushing rod in the control valve mechanism; The rear end is connected to a large diameter hole into which the rear end is fitted, and within this large diameter hole, a reaction disk made of a rubber material is inserted into the power piston when the booster is activated.
In the reaction force mechanism of the booster, which is arranged to be compressed between the valve plunger and the front force distribution member, a rigid body accommodates the reaction disk in the large diameter hole of the power piston. A case made of aluminum is provided, and the rear wall of the case is formed with a hole into which the front end of the valve plunger can be slidably inserted, and the small diameter portion provided at the rear end of the output member is slidably inserted into the front wall of the case. A reaction force mechanism for a booster, wherein a hole is movably inserted into the output member, and a gap is provided on the outer peripheral side of the small diameter portion of the output member to prevent the output member from coming into contact with the front surface of the case.
