Technical Examples

The object of the present invention is to provide an optimizing method for a groove structure of a friction disk of a wet-type friction engaging element, which can reduce drag torque by increasing outgoing flow of lubricating oil on the friction surface and increasing the content of air in the lubricating oil. The optimizing method for a groove structure of a friction disk of a wet-type friction engagement element comprising a sectoral inner section 12 of a groove 10 widening inwardly formed on the surface of a friction member of the wet-type friction engaging element, wherein the outgoing flow per groove area is calculated based on the entrance angle (opening angle) ? of the inner section 12 and the ratio h/w of the full length w of the groove 10 to the length h of the inner section; and then a range of the entrance angle (opening angle) ? of the inner section and the ratio h/w of the full length w of the groove to the length h of the inner section is determined where the outgoing flow per groove area is at least a certain value.
