Abstract
A lubricating device of a gear apparatus for a vehicle lubricates a low-rotation-side gear and a high-rotation-side gear meshing with the low-rotation-side gear. The lubricating device comprises a first tooth surface lubricating oil supply part configured to supply a lubricating oil directly to a tooth surface position located more upstream of a rotating direction of the low-rotation-side gear than a meshing position of the low-rotation-side gear with the high-rotation-side gear so as to spray some of the lubricating oil from the tooth surface position toward a tooth surface of the high-rotation-side gear, and an in-shaft lubricating oil supply part configured to supply the lubricating oil into a shaft of the high-rotation-side gear.
