An integrated pump device forms a module in which a motor (10), an oil pump (30) rotated by a driving force of the motor (10), and a hydraulic parking lock actuator (60, 70) are integrally constructed. The hydraulic parking lock actuator (60, 70) operates to switch between an advance state and a retard state by hydraulic pressure supplied from the oil pump (30), and locks a parking lock mechanism (80) of an automobile in the advance state and unlocks the parking lock mechanism (80) in the retard state. The oil pump (30) can supply oil for cooling or lubrication to an oil consumer (39) via the hydraulic parking lock actuator (60, 70).
