Claims

[Scope of utility model registration request]

It is equipped with a power cylinder provided with a power piston and a slave cylinder provided with a slave piston. A push rod is provided protruding from the power piston, and a pin is connected between the tip of the push rod and the slave piston. In the brake booster, the brake booster is configured to transmit the pressure of the power cylinder to the slave cylinder to perform a braking action, and the brake booster is configured to transmit the pressure of the power cylinder to the slave cylinder to perform a braking action. A disk is interposed therebetween, and a spring is provided on the seated disk so as to bias the seated disk toward the distal end of the push rod and bring the distal end of the push rod into contact with the seated disc. A brake booster characterized by:
