Each pin boss encompassing a boss hole is connected to a boss base body by a boss support, the base body having ribs to increase stiffness, which are aligned to the extent possible in the direction of the boss holes continuously connecting the pin bosses. The curved or arched ribs thereby cover a pivoting range of a connecting rod.
