A shift device for an automatic transmission of an automobile includes an indicator box affixed to the automobile floor. The indicator box has, in part, a wavy surface and a shift lever which is moved back and forth about an axle by an operator of the automobile. A spring-biased check ball is resiliently held in contact with the wavy surface of the indicator box, and is moved back and forth with respect to the axle in correspondence with motion of the shift lever. The position of the shift lever is regulated by the wavy surface of the indicator box and an indicator is visually provided, so that the shift lever stops accurately at positions of the indicator without needing adjustment during assembly of the selected shift device in a manufacturing assembly line.
