Abstract
There is provided a lubricating structure of a planetary gear mechanism which can simplify the outer shape of an introducing section formed by an oil catch plate, for introducing lubricating oil, and ensure a high degree of design freedom. In a double pinion type planetary gear mechanism, the distance from the axis of a carrier to the outermost edge of an opening in the direction of the carrier's diameter in an lubricating oil introducing hole formed in an outer diameter side pinion shaft and the distance from the axis of the carrier to the outermost edge of an opening in the direction of the carrier's diameter in an lubricating oil introducing hole formed in an inner diameter side pinion shaft are equal to each other. Therefore, lubricating oil can be supplied to the inner diameter side pinion shaft through the introducing section irrespective of the amount of lubricating oil that can be supplied to the outer diameter side pinion shaft. Also, the shape of a centrifugal cancel piston as the oil catch plate forming the introducing section can be simplified to increase the degree of design freedom.
