PURPOSE:To provide a liquid pressure boosting device for car brake, which multiplies the stamping force on a brake pedal through utilization of piston driving with a liquid pressure and transmits the boosted power to a master cylinder, in a simple construction, in light weight, at a low cost, with lesser generation of working sounds and vibrations, and in such a structure as not consuming electric power. CONSTITUTION:A brake liquid pressure boosting device includes a vacuum chamber 10 and a liquid pressure pump 15 to be driven thereby, and the pedal stamping force is multiplied through the action of liquid pressure given by the pump 15. The liquid pressure boosting mechanism shall be located in the center of the vacuum chamber 10. |
