Abstract
A lubrication apparatus in a vehicular power transmission unit includes device pinion shaft which is rotatably supported by a bearing disposed at a rear end portion of a casing. The casing contains lubricating fluid. A pickup member is disposed on the drive pinion shaft and picks up lubricating fluid upon rotation of the drive pinion shaft. A trough is formed on a wall of the casing in an inclined relation to the axis of the drive pinion shaft. The trough receives the lubricating fluid which is picked up and allows the lubricating fluid to flow under the influence of gravity to the rear end portion of the casing for lubricating the bearing located thereof.
