Abstract
In a vehicular parking lock device, the parking lock is actuated when a line pressure is supplied to a left end of a hydraulic actuator () via a second solenoid valve (A), or a hydraulic pressure of an accumulator () is supplied to the left end of the hydraulic actuator () via a third solenoid valve (B), and the parking lock is released when a line pressure is supplied to a right end of the hydraulic actuator () via a first solenoid valve (C,D). The second solenoid valve (A) and the first solenoid valve (D) also function as a solenoid valve that supplies the hydraulic pressure to a torque converter () and a solenoid valve that supplies the hydraulic pressure to a hydraulic brake () for shift change, respectively. Thus, it is possible to decrease the total number of solenoid valves, thereby cutting the number of components of a hydraulic circuit ().
