PURPOSE:To make it possible to perform a buffer action in the axial direction of an integral facing having both friction surfaces by providing stepped parts in the axial direction on both front and rear surfaces so that a large member of fan-shaped lining parts divided in the peripheral direction alternately form depressions and projections. CONSTITUTION:Fan-shaped lining parts 3 and 3' are pasted to both surfaces of the fan-shaped outer peripheral surface divided by cutout holes 2. Although stepped parts 4 and 4' traveling in an N-shaped peripheral direction are provided at the immediate inner peripheral part of the lining part 3, that is, between circular holes 2', adjacent stepped parts 4 and 4' are worked in the mutually opposite directions. Accordingly, adjacent lining parts 3 and 3' alternately form depressions and projections on the front and rear surfaces. In other words, the adjacent lining parts 3' have clearances 5' on the front side. That is, the lining part 3' has a clearance 5' on the front side while the lining part 3 has a clearance 5 on the back side, and these lining parts have stepped parts in the peripheral direction. |
