Patent abstract
A segment-type friction material has blocks each composed of four segment pieces. Five blocks are stuck by adhesion to a core metal 2 along an entire circumference thereof so as to constitute one surface of the segment-type friction material. Gaps are provided between the five blocks to form oil grooves that make an automatic transmission fluid (ATF) to flow. Five oil grooves are formed in total on one surface as a whole of the segment-type friction material.
