摘要：A vehicle hybrid driving apparatus that has an engine and an electric motor as drive power sources includes: a hydraulic pressure generation mechanism that generates hydraulic pressure using drive force from the engine; and a planetary gear ratio shift device that has three rotating elements: a first rotating element, a second rotating element, and a third rotating element. The first rotating element is linked to the electric motor so that power transmission therebetween is possible, and is also linked to the engine via a clutch so that power transmission therebetween is possible. The second rotating element is selectively linked to a stationary member via a brake. The third rotating element is linked to an output shaft so that power transmission therebetween is possible. The brake connects the second rotating element and the stationary member when the hydraulic pressure from the hydraulic pressure generation mechanism is not supplied.
