A gudgeon is attached to the core. Reinforcing ribs are laid on the end wall, the ribs, which radiate from the hub, extend over the contiguous portions of the cylindrical wall of the tank. The ribs are formed with a center core, preferably of foamed plastic. A belt track and a support ring are also formed integrally on the cylindrical wall of the tank.
