Abstract
A power transmission apparatus includes: an input shaft; a selectable one-way clutch; a housing case; a center support; a lubricating oil reservoir; and an oil passage. The oil passage extends through a pocket plate disposed between the lubricating oil reservoir and a selector plate. The selector plate includes a through-hole. The through-hole is located at a position where the through-hole is not lined up with the opening of the oil passage in a radial direction and a circumferential direction of the selector plate in a non-engagement state of the selectable one-way clutch, and also at a position where the through-hole is lined up with the opening of the oil passage in the radial direction and the circumferential direction of the selector plate in an engagement state of the selectable one-way clutch.
