<P>PROBLEM TO BE SOLVED: To provide a supporting structure for a planetary gear mechanism, that can secure a space on one side of planetary gears while suppressing the axial misalignment of a planetary carrier. <P>SOLUTION: The planetary carrier 23A rotatably supporting the plurality of planetary gears 22A includes a pinion shaft 230 rotatably supporting the planetary gears 22A, and an inside arm part 231 and an outside arm part 232 holding the pinion shaft 230. The planetary carrier 23A is supported on a case 11L by a bearing 33A supporting the pinion shaft 230 at one end side in the radial direction and a bearing 19A and a bearing 34A supporting the pinion shaft 230 at the other end side in the radial direction. The bearing 33A, the bearing 19A and the bearing 34A are arranged on one side of the planetary gears 22A in the axial direction. On the other side of the planetary gears 22A in the axial direction, no bearing is provided for supporting the planetary carrier 23A on the case 11L. <P>COPYRIGHT: (C)2013,JPO&INPIT |
