Abstract

A wet-type multi plate clutch is configured to be used for a transmission in an automobile. A clutch pack is provided with a plurality of drive plates and a plurality of driven plates. The drive plates have single surfaces on which first clutch facings are fixed and opposed surfaces on which annular grooves are formed along entire peripheral lengths. The driven plates have single surfaces on which second clutch facings are fixed and opposed surfaces on which annular grooves are formed along entire peripheral lengths. The sliding surfaces of the drive plates and the driven plates are arranged between the first and second clutch facings, which are axially adjacent with each other.
