PURPOSE:To eliminate a parking brake lever, by disposing, in an oil passage between a clutch master cylinder and a clutch release cylinder, a selector valve by which pressure oil from the master cylincer is fed to the parking brake. CONSTITUTION:A fluid passage selector valve 7 is disposed in a pipe line 5, 6 connecting between a clutch master cylinder 4 and a clutch release cylinder. The pipe 5 is branched off from this fluid passage selector valve 7, and is connected to a hydraulic cylinder 8 for a parking brake through a pipe 21. The above- mentioned fluid passage selector valve 7 is manually operated to be switched to one of the position where the pipe 5 is connected with the pipe 6 to actuate the release cylinder, the position where the pipe 5 is connected with the pipe 21 to actuate the hydraulic cylinder 8 and the position where oil in the hydraulic cylinder 8 is locked. |
