Lubricating structure of speed change mechanism

A lubricating structure of a speed change mechanism, the speed change mechanism including a planetary gear set that supports a third pinion gear by a carrier via a pinion shaft, the pinion gear revolving around a sun gear when the third pinion gear is rotating in the speed change mechanism, the lubricating structure of the speed change mechanism comprising:

• an oil receiver formed separately from the carrier and attached to the carrier, the oil receiver having a collecting portion configured to collect oil that is scattered from an inner diameter side of the oil receiver, the oil receiver being provided on a side opposite to the third pinion gear with respect to a first side plate of the carrier, and the oil receiver having a guide portion configured to guide the oil collected by the collecting portion, wherein
• the guide portion extends through the side plate of the carrier, and the guide portion has a first exit opening on a gear set radially inward side of a center of the pinion shaft to supply an oil flow to a tooth surface of the third pinion gear.
