<p><P>PROBLEM TO BE SOLVED: To provide a relatively low cost clutch operation device enabling clutch operation by a clutch pedal even if a trouble of an automatic hydraulic pressure generating device occurs. <P>SOLUTION: The clutch operation device is provided with a clutch booster 21 operating a clutch from an engaging state to a disengaging state when supplied hydraulic pressure is raised and operating the clutch from the disengaging state to the engaging state when raised hydraulic pressure decrease, the automatic hydraulic pressure generating device 24 generating hydraulic pressure by command of a controller 22, a clutch pedal device 30 generating hydraulic pressure proportional to step in quantity of a clutch pedal 30a, a hydraulic pressure selection device 31 connected to the automatic hydraulic pressure generating device 24 and the clutch pedal device 30 and supplying the clutch booster with higher hydraulic pressure of hydraulic pressure generated by the automatic hydraulic pressure generating device and hydraulic pressure generated by the clutch pedal device, and a solenoid valve installed in a hydraulic line between the automatic hydraulic pressure generating device and the hydraulic pressure selection device and reducing hydraulic pressure generated by the automatic hydraulic pressure generating device. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
