摘要： 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.

摘要： PROBLEM TO BE SOLVED: To provide a planetary gear device in which a uniform quantity of lubricating oil is supplied to a bearing between a pinion and a pinion shaft.
SOLUTION: An inner peripheral side lubricating oil feed hole 92a located on the inner peripheral side from a rotation locus A around an axis C passing the centerline of the pinion shaft 78, out of the inner peripheral side lubricating oil feed hole 92a and an outer peripheral side lubricating oil feed hole 92b provided in the pinion shaft 78 supporting the pinion 74 rotatably through a needle bearing 76, has a hole diameter larger than the outer peripheral side lubricating oil feed hole 92b located on the outer peripheral side of the locus A. The lubricating oil feed quantity difference between the outer peripheral side lubricating oil feed hole 92a and the inner peripheral side lubricating oil feed hole 92b is thereby reduced under the presence of centrifugal force. As a result, nonuniformity of lubricating oil supply is eliminated to obtain a uniform quantity of lubrication and also to obtain the durability of the planetary gear device 18 operated particularly at high speed rotation.

摘要： PROBLEM TO BE SOLVED: To sufficiently apply a lubricating oil to members which are arranged on the external circumference of a hollow rotary body and require to be lubricated, while ensuring rigidity of the hollow rotary-body.
SOLUTION: In a ring gear (hollow rotary-body) 26, a plurality of outward friction plates 80 and inward friction plates 82 requiring to be lubricated are provided, and lubricating holes 86 for communicating between the outside and inside circumferences with each other are made for oil-application to the outward frication plates 80 and the inward friction plates 82. Each of the lubrication holes 86 is made up of a diametrically expanded hole 86a and a smaller diameter hole 86b. The diametrically expanded hole 86a is opened on the external circumferential surface of the ring gear 26. The smaller diameter hole 86b has a diameter smaller than that of the diametrically expanded hole 86a, and allows the diametrically expanded hole 86a to communicate with the internal circumferential surface of the ring gear 26. Thus, the lubricating oil is applied to the wide area in the external circumference of the ring gear 26, and rigidity of the ring gear 26 is ensured, because the lubrication hole 86 has a smaller diameter except the diameter of the diametrically expanded hole 86a.
