PURPOSE: A brake booster for vehicle is provided to increase continued ratio and to reduce the size of an entire device by forming a brake booster as a braking power sub device of a machinery configuration. CONSTITUTION: A brake booster for vehicle includes an inputting rod(3), a muffler(9), and a braking power sub device(10). The cross section of the braking power sub device is formed into a dish shape. The central part of the braking power sub device is combined in a shape which the central part penetrates the inputting rod and is installed between a poppet valve(4) and the muffler. A gap is formed between the outer surface of the braking power sub device and a path. The path is divided into an inner chamber and an external chamber. |
