摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure for a planetary gear mechanism that allows a proper discharge of lubricating oil from the bearing of a planetary gear when the lubricating oil is supplied from a supply source of the lubricating oil to the bearing, and continues an oil supply to the bearing for a while even when the supply of the lubricating oil from the supply source is temporarily stopped.SOLUTION: The lubricating structure for a planetary gear mechanism includes: a planetary gear 30 that is capable of revolving while rotating around a main shaft 10; a planetary-gear shaft 31 that rotatably supports the planetary gear via a bearing 32; and a carrier 11 that supports the planetary-gear shaft. Lubricating oil is discharged from the main shaft. A guide plate 12 is provided near a guide-hole opening, formed in the planetary-gear shaft, so as to guide the discharged lubricating oil to the guide-hole opening while receiving the discharged lubricating oil, and the lubricating oil to the bearing. A sealing member 60 is provided near the end face on one side in the axial direction of the bearing and near the end face on the other side so as to be slidable to the discharging side and the sealing side of the lubricating oil guided to the bearing.
