Manual transmission

A manual transmission having a shift rail which is connected to a shift lever operable by a driver and which is supported by a housing so as to be axially movable, a sleeve connected to the shift rail via a shift fork, and a positioning mechanism for positioning the shift rail;

• the shift rail having end portions which respectively face surfaces of said housing, each of said shift rail end portions having an end face, and a plurality of engagement grooves formed at axial positions which respectively correspond to a plurality of gearshift positions;
• and said positioning mechanism being operable to engage with that engagement groove which corresponds to a desired gearshift position when the speed change for establishing the desired gearshift position is completed, the improvement comprising:
• one of said shift rail end portions moves in a direction apart from said positioning mechanism and approaching a corresponding one of the housing surface as said shift rail axially moves during said speed change;
• and
• said one shift rail end portion abutting on said corresponding one housing surface and said shift rail is axially held by the abutment between itself and said corresponding one housing surface and by said positioning mechanism after said speed change is completed.
