A brake booster for automotive vehicles comprises a low-pressure casing which is sealingly subdivided into a low-pressure chamber and a working chamber by a movable wall. The low-pressure casing is shaped to provide waists in the area of aligned bolts to fasten one end wall of the casing to a master brake cylinder and the other end wall of the casing to the vehicle. The casing has a casing wall section in the area of the waists extending in the axial direction to transmit tractive forces. In addition, tie elements may be provided outside the casing to interconnect the aligned bolts. |
