PROBLEM TO BE SOLVED: To provide a predetermined lubricating performance by sufficiently introducing lubricating oil into an axial oil passage of a support pin even when rotation of a planetary carrier is stopped without forcibly lubricating oil by guiding the lubricating oil from an oil pump to the support pin. SOLUTION: During rotation of the planetary carrier CA1, the lubricating oil flowing to the outer periphery side by a centrifugal force is made to flow into a first introducing section 56, introduced into the axial oil passage 44, and made to flow out of a through hole 48, thereby lubricating a needle bearing 38 or the like. During rotation stop of the planetary carrier CA1, the lubricating oil flowing down due to own weight flows into the first introducing section 56 or a second introducing section 60, and is introduced from an intermediate oil passage 52 into the axial oil passage 44, and is made to flow out of the through hole 48, thereby lubricating the needle bearing 38 or the like.
