PROBLEM TO BE SOLVED: To provide a hydraulic clutch device capable of being clutched-in with a strong operating force by a disk spring while avoiding a large-sized clutch drum.SOLUTION: A multiple-disk friction clutch part 42 is pressed into a clutched state with an overall elastic restoring force by an overlapping disk spring 32. The multiple-disk friction clutch part 42 is operated in a disengaged state by releasing the pressing operation of the disk spring 32 using a hydraulic piston 31 to which hydraulic pressure is supplied. The disk spring 32 and the hydraulic piston 31 are located on the opposite side of the position where the multiple-disk friction clutch part 42 is located with respect to a rim part 40c connecting between a drum part 40b of a clutch drum 40 and a boss part 40a. The hydraulic clutch device comprises an operation force transmission member 48 in which a rim part 40c is slidably inserted in an axial direction for transmitting the elastic restoring force of the disk spring 32 to the multiple-disk friction clutch part 42.SELECTED DRAWING: Figure 3

    【課題】クラッチドラムの大型化を回避しつつ、皿バネによる強い操作力で入り状態に操作できる油圧式クラッチ装置を提供する。【解決手段】重なった皿バネ32の総合弾性復元力によって多板摩擦クラッチ部42を入り状態に押圧操作する。油圧が供給された油圧ピストン31によって皿バネ32の押圧操作を解除することで多板摩擦クラッチ部42を切り状態に操作する。皿バネ32及び油圧ピストン31が、クラッチドラム40におけるドラム部40bとボス部40aとを連結するリム部40cに対して多板摩擦クラッチ部42が位置する側と反対側に位置している。リム部40cをスライド可能に挿通し、皿バネ32の弾性復元力を多板摩擦クラッチ部42に伝達する操作力伝達部材48を備えている。【選択図】図3
