Abstract
A brake booster is disclosed. More specifically, an improvement relating to a reinforcing plate which is used to reinforce a shell to which a master cylinder is connected is disclosed. The reinforcing plate comprises a pair of members, i.e. a first reinforcing plate which is disposed along the inner surface of the shell which provides a mounting surface for a master cylinder, and a second reinforcing plate which is disposed along the inner surface of the shell at a location radially outward of the mounting surface for the master cylinder. The rigidity of the shell can be increased without increasing a sheet thickness thereof.
