PROBLEM TO BE SOLVED: To improve the assemblability of an infinite variable speed drive to a transmission case without causing the upsizing of the infinite variable speed drive and the transmission case.SOLUTION: A transmission case 21 comprises: a first outer wall part 21a that supports an input gear 29; and a connection surface 21c and a plurality of through-holes 21d formed to enable an infinite variable speed drive B to be connected with, on an external surface of the first outer wall part 21a. A gear change case 24 of the infinite variable speed drive B comprises a composition plane 27a to be joined to the connection surface 21c and a plurality of screw parts 27b that correspond to the respective through-holes 21d. A plurality of screw components 58 are screwed into the corresponding screw parts 27b from outside a second outer wall part 21b, so that the infinite variable speed drive B is connected on the external surface of the first outer wall part 21a in a state that the composition plane 27a is joined to the connection surface 21c.
