Patent ID: 7909140

Claim:
A lubricating structure of a double pinion planetary gear mechanism, comprising: a carrier that supports an inner diameter side pinion shaft of an inner diameter side pinion and supports an outer diameter side pinion shaft of an outer diameter side pinion disposed on an outer side of the inner diameter side pinion shaft, the inner diameter side pinion shaft and the outer diameter side pinion being engaged with each other; and an oil catch plate provided on a side face of said carrier, said oil catch plate forming an introducing section for introducing lubricating oil from an inner diameter side of said carrier into the inner diameter side pinion and the outer diameter side pinion, wherein an inner diameter side lubricating oil introducing hole and an outer diameter side lubricating oil introducing hole for introducing lubricating oil are formed in respective end faces of the inner diameter side pinion and the outer diameter side pinion on a side of said oil catch plate, wherein a distance from an axis of said carrier to an outermost edge of the outer diameter side lubricating oil introducing hole in a direction of a diameter of said carrier and a distance from the axis of said carrier to an outermost edge of the inner diameter side lubricating oil introducing hole in a radial direction of the diameter of said carrier are equal to each other, wherein the inner diameter side lubricating oil introducing hole of the inner diameter side pinion shaft and the outer diameter side lubricating oil introducing hole of the outer diameter side pinion shaft are open to a common area of the introducing section, and wherein said common area extends circumferentially over the outer diameter side lubricating oil introducing hole and the inner diameter side lubricating oil introducing hole.
