Abstract
A clutch control hydraulic circuit includes first and second solenoid valves connected to a control unit, the first solenoid valve is provided between a first hydraulic pathway and a downstream junction hydraulic pathway normally switches to an open state when not energized, and switches to a closed state when energized; and the second solenoid valve is provided between a second hydraulic pathway and the junction hydraulic pathway, switches to a closed state when not energized, and switches to an open state when energized. The first solenoid valve maintains its closed state when switched to a non-energized state from an energized state while pressure of the junction hydraulic pathway is higher than that of the first hydraulic pathway, and when the first solenoid valve is thus closed in its non-energized state, pressurizing the upstream side hydraulic pathway by operation of a clutch lever opens the first solenoid valve.
