<p>PURPOSE:To reduce friction with an advantaged cost by securely acting a restoring elastic load on driven plates, and reducing the number of part items in a multiple plate tightening element where elastic members for holding a plate clearance are interposed between the adjacent driven plates. CONSTITUTION:A wave spring 5 is interposed between adjacent driven plates 4, 4. The wave spring 5 is fixed in a rotation stopping state in such a manner that a spring acting point S is disposed in a spline tooth portion 4c of the driven plate 4.</p> |
