As shown in FIG. 3, a conventional hydraulic clutch has a hydraulic cylinder 3 attached to a flywheel 2 connected to one end of an engine's crankshaft by bolts 5, and a clutch facing (not shown) is attached to this hydraulic cylinder 3. A first passage 7 is provided with a piston that presses in the connection direction via a pressure plate, and a hydraulic passage for supplying and discharging the hydraulic pressure to and from the chamber of the hydraulic cylinder 3 is provided in the shaft of the input shaft 6;
The flywheel 2 had a structure in which a second passage 8 communicating the passage 7 and the chamber of the hydraulic cylinder 3 was provided.

圧の制御が困難であつた。<Problems to be Solved by the Invention> In the conventional structure described above, the hydraulic cylinder 3 is provided at an outer circumferential portion of the flywheel 2 that is spaced apart from the center of rotation of the flywheel 2. This is because the bolts 5 for connecting the flywheel 2 to the crankshaft 1 hit the inner peripheral portion of the flywheel 2. Therefore, centrifugal force is applied to the oil in the chamber of the hydraulic cylinder 3 by the flywheel 2 rotating at high speed, and when the clutch is disengaged, the piston 4 is pushed in the direction of clutch engagement by the centrifugal force of the oil. However, it was difficult to control the hydraulic pressure because it sometimes caused poor clutch disengagement.

It is introduced into the end of the bolt 5 and is supplied into the chamber of the hydraulic cylinder 3 through a passage 14 provided in the shaft of the bolt 5 . As a result, the piston 4 moves forward and pushes the pressure plate 10 via the connecting member 11, and the pressure plate 10 presses the clutch facing 9 against the flywheel 2 to bring the clutch into the connected state. It is something to do.

Since it is installed inside the center of rotation and the piston and pressure plate are connected by a ring-shaped connecting member, the influence of the centrifugal force of the oil in the hydraulic cylinder chamber that rotates together with the flywheel is reduced. This has the advantage of solving the problem of clutch disengagement. Further, even if the head of the bolt, which serves as the hydraulic pressure supply/discharge passage, is located in the hydraulic cylinder chamber, the pressure receiving surface of the piston remains unchanged, so that a sufficient force for engaging the clutch is ensured.
