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.
