Claims

[Scope of utility model registration request]

The interior of the housing, which is made up of a pair of front shells and a palm shell, is formed by a fixed wall, a front movable wall and a rear movable wall arranged before and after the fixed wall, forming a front constant pressure chamber, a front variable pressure chamber, a rear constant pressure chamber, and a rear variable pressure chamber. The front constant pressure chamber and the rear constant pressure chamber are connected to a negative pressure source and linked to the pedal, and the front variable pressure chamber and rear variable pressure chamber are selectively connected to the front constant pressure chamber, the rear constant pressure chamber, and the atmosphere. a control valve mechanism that communicates with the front movable wall and the rear movable wall, and a reaction mechanism that transmits the forward force of the front movable wall and the rear movable wall to the piston of the master cylinder coupled to the front shell, and transmits a portion of the reaction force from the piston to the control valve mechanism. In the tandem booster for a vehicle, the front movable wall is guided by the rear shell and the fixed wall, and the control valve mechanism is built into the rear movable wall. A tandem type booster for a vehicle, which is abutted and supported by a rear movable wall so as not to tilt, and the reaction force mechanism is built into the front movable wall.
