PROBLEM TO BE SOLVED: To provide an oil supply structure capable of adjusting flow rate of oil supplied to a clutch and flow rate of oil supplied to a pinion with a simple construction.SOLUTION: An oil supply structure comprises: an oil supply passage 6 provided in a clutch drum 10 of a forward clutch 2; an oil chamber 7 which is formed between the forward clutch and a planetary gear mechanism and is supplied with oil through the oil supply passage; a partition member 8 arranged in the oil chamber; and a connection member 9 which connects the partition member and a movable member of the forward clutch and is elastically deformable. The oil chamber is divided into a clutch oil chamber 7b and a pinion oil chamber 7a by the partition member. The partition member has an oil hole 8a providing communication between the clutch oil chamber and the pinion oil chamber. The connection member abuts against the partition member to close the oil hole in a disengagement state of the forward clutch and, in an engagement state of the forward clutch, is deformed by the pressing force transmitted via the movable member to release the oil hole and allow oil to flow from the pinion oil chamber into the clutch oil chamber through the oil hole. |
