打ち抜く際に行っても良いし、単独に行っても良い。To be more specific, the back-up material of the present invention is formed into a ring plate from a light metal such as aluminum or duralumin, and suitably has a thickness similar to or thicker than that of the clutch facing member. If it is thicker than the clutch facing member, the specific gravity will increase, which is not preferable. Further, this back-up material is formed with ribs so as to increase the bending strength in the circumferential direction. The shape of the rib is not particularly limited, and may be, for example, an annular groove as shown in FIG. 2, a groove formed by folding the outer periphery and inner periphery as shown in FIG. An annular groove having a wavy cross-sectional view, circular or elliptical irregularities discontinuous in the circumferential direction as shown in FIG. 5, etc. can be appropriately selected and formed. The ribs may be formed when the backup material is punched out from the original plate, or may be formed independently.
