PROBLEM TO BE SOLVED: To provide a hydraulic clutch device capable of preventing generation of an operating pressure in a hydraulic clutch in a state of free from an indicated hydraulic pressure by reducing resistance of a discharge-side oil passage in which an oil discharged from a pressure regulation valve is circulated.SOLUTION: A hydraulic clutch device includes a case in which a pressure regulation valve is disposed at a downstream side in an oil flowing direction, of a hydraulic clutch 5R, and which receives the hydraulic clutch, an insertion hole for inserting at least a part of the pressure regulation valve 8R disposed in the case, an upstream-side oil passage 67R having an opening portion opened to the insertion hole, and leading the oil discharged from the hydraulic clutch from the opening portion to the insertion hole, and a downstream-side oil passage 60 having the other opening portion opened to the insertion hole and leading out the oil from the other opening portion to a downstream-side of the insertion hole. A position of a first virtual line L1 passing through a point of the center of gravity of a cross-section of the opening portion of the upstream-side oil passage 67R and a position of a second virtual line L2 passing through a point of the center of gravity of a cross-section of the insertion hole are different from each other.SELECTED DRAWING: Figure 2

    【課題】調圧弁から排出されるオイルが流通する排出側の油路の抵抗を低減できるようにすることで、指示油圧が無い状態で油圧クラッチに作動圧が発生することを防止できる油圧クラッチ装置を提供する。【解決手段】調圧弁を油圧クラッチ5Rのオイル流れ方向下流側に配置するとともに、油圧クラッチを収容するケースと、ケースに設けた調圧弁8Rの少なくとも一部を挿入する挿入穴と、挿入穴に開口する開口部を有し開口部から挿入穴に油圧クラッチから出たオイルを導入する上流側油路67Rと、挿入穴に開口する他の開口部を有し他の開口部から挿入穴の下流側にオイルを導出する下流側油路60と、を備え、上流側油路67Rの開口部の断面の重心点を通る第1仮想線L1の位置と、挿入穴の断面の重心点を通る第2仮想線L2の位置とを互いに異ならせて配置した。【選択図】図2
