Zusammenfassung:	PURPOSE: To make improvements in strength to the retention for clutch hydraulic pressure as reducing an increase of weight by providing a wall thickness part in and around an opening of each root part outer surface of a spline projected toward a rim part outer boundary, and forming a snap ring fittling groove in this wall thickness part. CONSTITUTION: When a piston 15 is operated by dint of hydraulic pressure, both driven and dividing plates 11 and 12 are pressed by a rim part 15a of this piston 15, whereby the connectedness of a multiple disk clutch 10 is formed there. At this time, a snap ring 9 makes a reaction be generated in a snap ring groove 8 against strong pressure of the piston 15 and thereby hydraulic force is maintained, but this snap ring fitting groove 8 is formed in an intermediate part of a wall thickness part 14 of a spline 5 in the vicinity of an opening of this snap ring fitting groove 8. Therefore, owing to this formation, any wall thin part will not be produced at all in and around the fitting groove 8, so that an improvements in strength of a multiple disk clutch drum to the retention for clutch hydraulic pressure is made achievable as reducing an increase of weight.
