ABSTRACT:
In a segment-type wet friction material, an inner peripheral left corner of one segment piece and an inner peripheral right corner of another segment piece are respectively cut off at a fixed angle to a center line of an oil groove. The oil grooves have first oil grooves and second oil grooves. The second oil groove has nearly a uniform width. The first oil groove has an inner peripheral corner portion that is broadened to the center line of the oil groove from a fixed height. In case of being assembled in an automatic transmission, when the segment-type friction material rotates in one direction, an automatic transmission fluid supplied from an inner circumference bumps and touches the portion that is broadened at the fixed angle at a rear side in the rotating direction.
