<p>When a shift lever is in a reverse (R) position, a brake B2 is engaged by a reverse pressure PR from an R position output port 58c of a manual valve 58, and a clutch C3 is engaged by an SLC3 pressure from a linear solenoid SLC3, thereby forming a state of a first reverse speed. When the shift lever is in a neutral (N) position, a brake B2 is engaged by supplying the SLC3 pressure from the linear solenoid SLC3 to the brake B2 instead of the clutch C3, thereby forming a state of neutral. Accordingly, it is not necessary to provide a dedicated linear solenoid for engaging the brake B2. Consequently, by suppressing increase in consumption flow rate (energy consumption) in a hydraulic circuit 50 due to separately providing a linear solenoid, energy efficiency of the entire apparatus can be improved, and the entire apparatus can be downsized.</p> |
