A manual transmission includes a shift rail (6) connected to a shift lever (1) and supported by a housing so as to be axially movable, a sleeve (8) connected to the shift rail (6), and a poppet plug (13) for positioning the shift rail (6). When the speed change is completed by the operation of shift lever (1), the positioning ball (15) of the poppet plug (13) engages with one of poppet grooves (6a,6b,6c) formed in the shift rail (6), and the end face of the shift rail (6) abuts on the housing surface (6d). As a result, the shift rail is axially held by the housing surface (6d) and the positioning ball (15) of the poppet plug (13), so that the axial displacement of the shift rail (6) is prevented. For this reason, even if a vibration occurs on the sleeve, the transmission of vibration from the sleeve (8) to the shift lever (1) via interposing elements including the shift rail (6) is prevented, whereby a feeling of shifting operation is improved. <IMAGE> |
