Abstract: A click mechanism in the automatic power transmission gear selector device is mounted onto a bracket for mounting a control rod of the selector device onto a steering column and directly associated with the control rod. By this, click in shifting the automatic power transmission can be directly transmitted to the selector lever through the control rod.

Abstract: A safety system for a motor vehicle having an automatic transmission, a shift lever movable into select positions for allowing the transmission to assume the corresponding gear conditions thereof, stepped operation surfaces, and a stop pin movable with the shift lever and slidably engageable with the stepped operation surfaces for retaining the shift lever at one of the select positions. A position detector switch is provided which connects the starter motor of the vehicle with an electric power source. The position detector switch includes at least one stationary contact member mounted to one of the stepped operation surfaces, and a single movable contact member mounted to the stop pin at the portion engageable with the stepped operation surfaces.

Abstract: In a shift lever mechanism of a vehicle automatic transmission, there is provided a detent feeling generating mechanism which gives the driver an assured detent feeling upon shifting from "D" position to "2" position or vice versa. The detent feeling generating mechanism comprises a plate member which is stationary relative to the vehicle body and which has a stepped cam surface, a cylindrical rod swingable about its axis in response to the shifting movement of a shift lever relative to the plate member, a tubular housing fixed to the cylindrical rod to be swingable therewith and having a ball rotatably mounted in the free end thereof, and a spring disposed in the tubular housing to bias the ball to project outwardly so that the ball is forced to engage the stepped cam surface of the plate member.
