<P>PROBLEM TO BE SOLVED: To provide a gear device having a lubricating oil supply control mechanism for increasing supply of lubricating oil to the gear device, when transmitting torque is large, by squeezing the supply of the lubricating oil to the gear device, when the transmitting torque is small, without increasing the number of part items. <P>SOLUTION: When thrust force F does not act on a pinion gear 120, an oil passage between a side surface of the pinion gear 120 and a side surface of a carrier 160 is closed, and the supply of the lubricating oil to the tooth surface side of the pinion gear 120 is restricted. While, when the thrust force F acts on the pinion gear 120, the oil passage between the side surface of the pinion gear 120 and the side surface of the carrier 160 is opened, and the supply of the lubricating oil to the tooth surface side of the pinion gear 120 is urged. <P>COPYRIGHT: (C)2011,JPO&INPIT |
