ABSTRACT:
A gear-shifting safety device is provided for an all-terrain vehicle (ATV), including a gear lever, a gear-shifting hub shaft, a gear-shifting gear set, and a reversing bar. An end of the gear-shifting hub forms a step on which a block is provided. The block and the step form a stop face therebetween. The reversing bar has an end forming a stop section that is positionable on the step and is selectively in abutting engagement with the stop face so that to change to the reversing position, the reversing bar must be first actuated to disengage the stop section thereof from the stop face, allowing the switching fork to move to the reversing position on a position chute of the gear-shifting hub, thereby eliminating the damage of accidentally switching to reversing during the forward movement of the vehicle.
