Abstract
A ring gear of a dual planetary gear, or a big ring gear is fixed on a peripheral section of a disc type supporting member, and both sides of the supporting member are supported by thrust bearings situated in small radius section of the supporting member. The ring gear of the planetary gear unit is fixed on the peripheral section of the disc type supporting member. The supporting member is held and supported between a side of a carrier of the planetary gear unit and a boss section on a counter gear through thrust bearings. The ring gear rotates when an automatic transmission operates. Then the supporting member also rotates, but the bearings are situated at a portion where rotative speed is low, so that the bearings receive thrust force based on the low speed rotation. The supporting member has a groove and a step-like section to set the bearings.
