PROBLEM TO BE SOLVED: To minimize distance between bearings of two rotary shafts disposed on the same rotation axis, and to realize light weight and compactness of a transmission. SOLUTION: An engine side end part of a secondary shaft 9c is journaled through a first needle bearing 39 supported by a first bearing support part 38a of a bearing support member 38. An output shaft 13 of a continuously variable transmission 9 is inserted into the secondary shaft 9c, and a reduction gear shaft 15 is connected to the engine side end part. A counter-engine side end part of the reduction gear shaft 15 is journaled through a second needle bearing 41, supported by a second bearing support part 38b of the bearing support member 38, and having larger inner diameter than outer diameter of the first needle bearing 39. The second bearing support part 38b of the bearing support member 38 is formed at such a position that the second needle bearing 41 is supported to be overlapped with the first needle bearing 39 on the outer side of the first needle bearing 39.
