AbstractA brake booster, in particular, a construction for strengthening the coupling between the brake booster and a master cylinder, is disclosed. The head of a bolt which extends through an enclosed shell is welded to the internal surface of the shell so as to maintain a hermetic seal, and a strengthening plate disposed around the bolt head is welded to the internal surface of the shell. Additionally, a reinforcing member fixedly connected to the strengthening plate is welded to the bolt head to improve the rigidity of the strengthening plate.
