    • An outer tapered member (4) having a conical inner circumferential surface is placed and an inner tapered member (5) having a conical outer circumferential surface in contact with the conical inner circumferential surface is placed in a through hole (31) of a first ring (1). A screw member (6) is screwed a predetermined quantity into the through hole (31) to axially press an axial end face of the inner tapered member (5) toward a second ring (2) with a predetermined force and to press the outer surface of the outer tapered member (4) against the through hole (31) of the first ring (1) with a predetermined force. A weld part (7) in contact with a first ring (1) side end portion of a pin (3) and the first ring (1) is formed to prevent the pin (3) from coming out of the first ring (1) by the weld part (7).
    • 放置具有圆锥形内圆周表面的外锥形构件(4),并且具有与锥形内圆周表面接触的锥形外周表面的内锥形构件(5)放置在第一环的通孔(31)中 (1)。 螺杆构件(6)以预定的量拧入到通孔(31)中,以预定的力将内锥形构件(5)的轴向端面向第二环(2)轴向推压,并且将外表面 的外锥形构件(4)以预定的力抵靠第一环(1)的通孔(31)。 形成与销(3)的第一环(1)侧端部和第一环(1)接触的焊接部(7),以防止销(3)从第一环(1)中脱出, 通过焊接部(7)。
