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