PROBLEM TO BE SOLVED: To reduce entire length of a reduction gear.SOLUTION: An output shaft 14 of a reduction gear 1 is rotatably held by a first main bearing 41 and a second main bearing 42. The first main bearing 41 is sandwiched and held between a first support part 52 formed on a case 11 and a carrier 20 so as to support a portion of the first main bearing 41 opposite to the carrier 20. The second main bearing 42 is sandwiched and held between an output shaft side support part 14b formed on the output shaft 14 to support a portion of the second main bearing 42 opposite to the carrier 20 and a second support part 56 formed on the case 11 to support a portion of the second main bearing 42 on the carrier 20 side. A fixing member 45 is arranged at a portion of the carrier 20 opposite to the first main bearing 41, and a spline part 40 formed on the output shaft 14 extends at least to the first main bearing 41 at an end on the first main bearing 41 side. |
