PURPOSE:To obtain a low-priced hydraulic cylinder which presses a release hub uniformly over periphery by providing an oil supply means which supplies oil to a cylinder chamber due to stepping of a clutch pedal between the cylinder chamber and clutch pedal. CONSTITUTION:Oil is supplied from a master cylinder 21 of an oil supply means 23 via a hose 22 to a cylinder chamber A by stepping on a clutch pedal 20. At this time, a circular piston section 17 of a release hub 15 is inserted into the cylinder chamber A. The whole periphery of the release hub 15 is pressed in axial direction by oil. It comes in contact with a clutch release chamber 5 via a release bearing 16 and pushes the release bearing 16, thereby releasing clutch 1. |
