A center wheel bridge is mounted on the main plate and a pillar-shaped member having a tubular region and a perpendicular disc-shape region is mounted in an opening in the center wheel bridge for supporting the cannon pinion which passes through the main plate about the tubular portion of the pillar-shaped member.
