Abstract

A reverse idler gear mounting structure is easily and reliably assembled in a manual transmission. The transmission has a transmission case with an end wall and a side wall, input and main shafts extending in parallel in the transmission case and having rear ends directed toward the end wall, mutually engaged input and main gears operatively mounted on the input and main shafts respectively, synchronizing mechanisms operatively incorporated with the input and main gears to provide the transmission with a selected gear ratio, reverse input and main gears operatively disposed on the input and main shafts respectively, an idler shaft fixed to the rear wall and a reverse idler gear rotatably disposed on the idler shaft while meshing with both the reverse input and main gears. The reverse idler gear mounting structure comprises a first through bore formed in the rear wall, the first through bore extending in parallel with the input and main shafts and having a size to permit insertion of the idler shaft into the transmission case therethrough; a second through bore arranged coaxial with the first through bore and formed in an inner wall which extends inward from the side wall, the inner…
