Claims

[Claims for Utility Model Registration] 1. In a brake booster in which a reaction disk is interposed between an input side member and an output side member, the contact area between the input side member and the reaction disk depends on the magnitude of the input. A brake booster characterized in that the brake booster changes according to 2. An elastic body in which the input side member has a truncated conical head, the head is brought into contact with a reaction disk, and the reaction disk retracts the head of the input side member depending on the magnitude of the input. A brake booster according to claim 1, which is manufactured by Utility Model Registration.
