PURPOSE:To gradually connect a hydraulic clutch by operating an operation lever, whereby a master cylinder is operated by a piston to feed low initial pressure oil to a clutch cylinder of the hydraulic clutch. CONSTITUTION:A piston 4 is operated, interlocking with an operation lever 3 for operating a clutch switch valve 2. A master cylinder 5 is provided with an oil path for supplying low initial pressure oil to a clutch cylinder 15 of a hydraulic clutch 1 through a clutch switch valve 2 by operation of the piston 4. At the end of initial pressure oil supply, pressure oil of an oil pump 14 is supplied to the clutch cylinder 15 through the clutch switch valve 2. Thus, the response of the operation lever is caused to gradually perform clutch connecting operation. |
