  • Publication number: 20150260276
    Abstract: In a shifting device for a vehicle, inner walls of a guide groove of a main body which are opposed to each other with a guide protrusion interposed therebetween are parallel to each other. The guide protrusion is formed with a width dimension that is reduced from a given position toward a proximal end thereof, so that an angle formed between a line that is parallel to a center axis of the guide protrusion and is extended from the given position toward the proximal end of the guide protrusion as an extension of a line on a side face of a distal end portion of the guide protrusion, and a line on a side face of the proximal end portion of the guide protrusion extending from the given position, becomes equal to a given angle. Thus, the side face of the proximal end portion of the guide protrusion is prevented from strongly contacting with the inner wall of the guide groove which is opposed to the side face, and stress is prevented from being concentrated in the guide protrusion.
