<p>PROBLEM TO BE SOLVED: To sufficiently cancel centrifugal oil pressure generated in an engagement oil chamber while making a multi-plate clutch compact.SOLUTION: A clutch C2 of an automatic transmission 25 has a cancel plate 240 including a flange part 243 defining a cancel oil chamber 235 for cancelling centrifugal oil pressure generated in an engagement oil chamber 225 together with a piston 220. The flange part 243 of the cancel plate 240 extends nearer the piston 220 than a separator plate 205 and a friction plate 215 and on an outer side than an inner periphery of the separator plate 205, and a seal member 246 is arranged between the piston 220 and an outer peripheral part of the flange part 243.</p> |
