ABSTRACT:
Disclosed herein is a mechanism for preventing misoperation, that is, change from a four-wheel drive operation to a two-wheel drive operation at a low speed geared position or select-operation to a low speed gear during a two-wheel drive operation in a manual transmission which permits change from a two-wheel drive operation to a four-wheel drive operation and vice versa and also permits a shift-operation to a low speed gear upon running on a steep slope, sandy place and rough road. The mechanism comprises a stopper arm extending from a shift-and-select lever toward a drive changing shaft and a stopper surface formed on one end of the drive changing shaft. The stopper surface is effective to abut against the stopper arm in the two-wheel drive position of the drive changing shaft and is effective to prevent the shift-and-select lever from engaging the shift head fixed to the fork shaft for a low speed gear.
