The pinion carrier shown here is formed by joining two annular members. The first member of the two members has a boss portion formed with a spline that engages with the rotating shaft in the center thereof, and a planar disk-shaped portion extending from the boss portion in the outer radial direction.
The second member has bent portions in the axial direction of the rotating shaft at three locations on the same circumference, avoiding the pinion mounting portion. The two members are joined by electron beam welding between the outer periphery of the planar disk-shaped portion of the first member and the inner periphery of the bent portion of the second member.
