A power transmission unit adapted to optimize an oil delivery amount to oil requiring site is provided. A selectable one-way clutch comprises a selector plate that is rotated to a position to bring the selectable one-way clutch into engagement, and to a position to bring the selectable one-way clutch into disengagement. The selector plate comprises a valve plate crossing an oil passage for delivering lubrication oil to the planetary gear unit. The valve plate comprises a through hole that is overlapped with the oil passage to open the oil passage by rotating the selector plate to the position to bring the selectable one-way clutch into engagement, and that is displaced from the oil passage by rotating the selector plate to the position to bring the selectable one-way clutch into disengagement.
