ABSTRACT:
A manual power transmission includes a transmission casing, input and output shafts coaxially aligned with each other and a countershaft accommodated within the transmission casing and positioned below the input and output shafts. The input and output shaft has a plurality of gears of a varying size or diameter mounted thereon and associated with gearshifting positions and the countershaft has a corresponding number of coutergears of a varying size or diameter mounted thereon and paired with the gears on the input and output shafts. Some of the countergears which serve as an idle gear are so juxtaposed in a direction axially of the countershaft that an envelope enclosing all of the those countergears while touching respective outer perimeters of those remaining countergears represents a generally barrel shape having a generally intermediate portion thereof bulged radially outwardly with respect to the countershaft.
