Gearbox selector mechanism for manual transmission

摘要

A changing system in a manual transmission is provided. An interlock plate (68) is mounted on a shift-selecting shaft (73) capable of being moved axially in response to a selecting operation and turned about an axis in response to a shifting operation, so that the interlock plate cannot be turned about an axis of the shift-selecting shaft. The interlock plate has a pair of side plate portions (86a,86b) which are provided at locations spaced apart from each other in an axial direction of the shift-selecting shaft and through which the shift-selecting shaft extends. A shifting arm (90) disposed between the side plate portions is fixed to the shift-selecting shaft. In such changing system, the shifting arm and an interlock member operatively connected to the shifting arm are interposed between the side plate portions of the interlock plate. Thus, the shifting arm can be used commonly in manual transmissions, in despite of a difference in number of forward speed stages between the manual transmissions, thereby providing a reduction in cost and avoiding an increase in weight due to a variation in number of forward speed stages.
