PURPOSE:To facilitate assembling and adjusting work by incorporating a transmission mechanism onto a driving shaft outside a transmission case beforehand and inserting the driving shaft into the transmission case and allowing a partitioning wall to axially support the rear part of the driving shaft. CONSTITUTION:The front part of a driving shaft 5 is axially supported, through a bearing 4, onto the rear part of an input shaft 3 which rear part is axially supported by a bearing 2 onto the partitioning wall 1a of a transmission case 1, and the axially supporting part 5a is axialy supported onto a partitioning wall 1b through a bearing 6, projecting the gear 5b, formed at the back of the axially supporting part 5a of the driving shaft 5, rearward from the partitioning wall 1b. The bearing inserting hole 7 formed on the partitioning wall 1b for inserting the bearing 6 is formed larger than the gear 5b. On assembly, a transmission mechanism 8 is incorporated onto the driving shaft 5 outside the case and the bearing 6 is inserted into the axially supporting part 5a, while the driving shaft 5 is inserted from an upper hole 1c and the bearing 6 is fixed by a pressing body 9.
