Abstract
The wet friction member 1 of the invention includes a core plate 2 formed in a flat ring shape, a friction part 3 arranged in a ring shape. The friction part 3 has segment pieces including rectangular shaped G1 to G4: G1 in which a lower right corner of rectangular piece is notched; G2 in which an upper left corner of rectangular piece is notched; G3 in which an upper right corner of rectangular piece is notched; G4 in which a lower left corner of rectangular piece is notched. The friction part 3 has arrangements T1 and T2: T1 in which G1 and G2 are arranged in a manner a right side of G1 and a left side of G2 face each other; T2 in which G3 and G4 are arranged in a manner a right side of the G3 and a left side of G4 face each other.
