Abstract

PURPOSE:To stabilize friction characteristic by making grooves constituted of arcs having radii larger and smaller than the radius of a clutch board in a circular clutch board. CONSTITUTION:About twelve grooves are formed radially in a circular clutch board 1. An imaginary arc having a radius (r1) larger than that of the clutch board 1 is formed around a center which is separated by a distance (a) from the center A of the clutch board 1. Then another imaginary arc having a radius (r2) smaller than that of the clutch board 1 is formed around a center separated by a distance 2<1/2>b from the center A of the clutch board 1. When there is relations shown by formulas I, II between the distances (a), (b) and the radii, (r1), (r2), grooves are formed along an imaginary closed curve 3 formed by connecting the imaginary arcs. Consequently, the distance between the center of circle and the closed curve varies periodically around the closed curve.
