ABSTRACT:
A planet carrier of an automotive automatic transmission includes an annular main body portion disposed around a pinion shaft between the carrier body and the pinion gear. A washer formed of a porous material such that lubricating fluid can flow therethrough to both sides of the washer is disposed around the pinion shaft. Further, a boss portion may be formed at the inner periphery of the washer opening, which portion is inserted between the surface of the pinion shaft and an inner circumference of the pinion gear. A fluid passage is defined according to installation of the washer, between the edge of the washer and the bearings of the pinion gear such that lubricating fluid is retained therein, which fluid flows around the pinion shaft.
