A part of the cut portion on the outer peripheral edge side extends radially outward at a plurality of locations at appropriate circumferential intervals, and the radially extending portion between the contact portions for the outer ring and the inner ring of the one-way clutch is The annular portion excluding the ring protrudes in the axial direction to form a guide portion for the inner race of the thrust needle roller bearing, and the radially extending portion is formed at the step portion between the outer circumferential edge side and the inner circumferential edge side of the guide ring. An assembly according to claim 1, wherein an opening is formed. (6) The locking portion for the inner loop of the thrust needle roller bearing of the coupling plate is located at one of the openings formed in the stepped portion between the outer circumferential edge side and the inner circumferential edge side of the guide portion of the coupling plate, The assembly according to claim 4 or 5, wherein the locking hole is a plurality of locking holes provided in one of the step portions. (7) The annular portion between the outer and inner rings of the one-sided clutch, which is taken from the outer and inner portions of the coupling plate, is cut in the radial direction at appropriate circumferential intervals. An opening that protrudes outward and inward in the direction and expands in the axial direction on the circumferential edge, and has a radial receiving part for the outer ring and the inner ring of the one-way clutch, and a guide part for the inner race of the thrust needle roller bearing, respectively. A thrust needle roller bearing is formed by bending a protruding edge portion with claws at the tip at multiple locations in the axial direction on the guide @s side of the inner circumferential edge of the portion that is still in contact with the inner ring of the one-way clutch. 2. An assembly as claimed in claim 1 in which a retainer is formed for the inner race. (8) The assembly according to claim 7, wherein the locking portion of the coupling foot for the inner assembly 1 of the thrust needle roller bearing is a catch provided in the holding portion of the coupling plate. (9) The locking part of the coupling plate for the outer ring of the one-sided clutch is arranged so that the outer circumferential edge or the inner circumferential edge of the abutting part of the coupling plate for the outer ring or inner ring of the one-sided clutch is in the axial direction toward the guide part side or the radial receiving part side. A patent that is a plurality of protruding edge portions formed by bending or a plurality of notch portions formed by bending a part of the outer peripheral edge of the corresponding contact portion in the diagonal direction of the radial receiving portion @1] An assembly according to claim 4 or 5 or 7.
