Abstract

A liquid pressure generating apparatus including a pump; and two one-way clutches arranged coaxially with the pump's drive shaft. Inner races of the respective two one-way clutches are integrated with each other to form a common inner race. Outer races of the respective two one-way clutches are formed independently from each other and are driven respectively by pump driving members different from each other. The common inner race includes a coupling portion coupled to the pump drive shaft and extending in the radial direction and a cylindrical body portion extending from the coupling portion in a second axial direction opposite from the first axial direction on the radially outside the pump drive shaft. The body portion includes a depression indented radially outward on an inner peripheral surface thereof. A lubricant supply portion for the depression is provided radially inside the depression.
