Document Type and Number:
Japanese Patent JP5502720
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a power transmission device that prevents a reduction in NV performance and durability due to a poor engagement of a planetary gear mechanism by preventing deformation of a hollow support and an annular support when the eccentric load of a damper mechanism is applied to an input shaft.SOLUTION: A transaxle is configured to separate a rotation central axis of a needle bearing 55 that supports the input shaft 28 by the hollow support 25c of a case 25 and a ball bearing 53 that supports the inner circumference of a ring gear 23R by the annular support 25b of the case 25 formed on the outer circumference of the hollow support 25c in an axis direction of the input shaft 28, and to locate the center in an axis direction of the rotation central axis of the needle bearing 55 on the axis of the wall 25d of the case 25.
