An input shaft 10 is connected rotationally with an intermediary shaft 20 through a main drive gear GMV, a connecting idle gear GCC and a connecting driven gear GCN and also connected rotationally with a countershaft 30 through the main drive gear GMV and a main driven gear GMN. A fourth speed drive gear G4V, which is provided on the countershaft 30, meshes with a fourth and sixth speed drive gear G46V, which is provided rotatably over the input shaft 10. Both the fourth and sixth speed drive gear G46V and a fifth speed drive gear G5V, which is provided rotatably over the intermediary shaft 20, mesh with a fourth, fifth and sixth speed driven gear G456N, which is provided on the output shaft 50.
