Abstract: A shift lever device for an automatic transmission comprises a lock plate rotatably supported by a pair of supports and formed with a step that cooperates with a detent recess of a position plate to prevent vertical and longitudinal movements of a position pin at least in the neutral (N) range. The lock plate is rotated to engage with the detent recess when the position pin is moved to the N range.

Abstract: A shift lock arrangement for an automatic transmission shift lever device having a shift lock lever in contact with a position pin of the shift lever device positioned in a parking position has a lock lever in contact with the shift lock lever to restrict the movement of the position pin in the parking position. A key lock unit is connected with the shift lock lever so that the shift lock lever keeps latching the position pin in the parking position when an automotive key is not set therein. A slidable stopper pin is connected with a push rod pushed by a brake pedal in a released condition. The stopper pin latches the shift lock lever so as to prevent the movement of the position pin from the parking position to the other positions when the brake pedal is in the released condition. When the brake pedal is depressed, the push rod is released from the brake pedal and the stopper pin is disengaged from the shift lock lever.

Abstract: The invention provides a gear position indicating arrangement in an automatic transmission shift control device which makes it possible to obtain two kinds of devices, i.e., one for a right-hand drive vehicle and one for a left-hand drive vehicle, using a number of common parts. In the device, a base bracket is a common part and can be used for both of the kinds. An indicator cover to be installed on the base bracket can also be used for both of the kinds by reversing the front and rear ends thereof in case of a left-hand drive vehicle as compared with those in case of a right-hand drive vehicle. A bulb case is a part independent from the indicator cover and the base bracket and adapted to be fastened to a right-hand side of the base bracket in case of a right-hand drive vehicle and to a left-hand side of the base bracket in case of a left-hand drive vehicle.

Abstract: A shift lever structure (E) for operating an automatic transmission of a vehicle, includes a frame (10) fixed to a floor of the vehicle, a shaft (20,21,22) rotatably supported by the frame, a shift lever (30) and a select lever (40) connected with the automatic transmission. Both the shift lever and the select lever are molded integrally with the shaft by the insert-molding technique. In the arrangement, the lower end portion of the shift lever is engaged with the upper end portion of the select lever at an L-shaped bend (41). In operation, a force applied on the shift lever can be transmitted to the select lever directly, thereby reducing any twisting movement applied to the shaft. Therefore, it is possible to improve the strength of both levers and to decrease the strength required for the shaft.

The automatic transmission operating device comprises a pair of bearing sections which are located separate from each other and fixedly connected to a base fixed to a vehicle floor. Each bearing section includes a generally cylindrical portion having a generally C-shaped cross-section so as to define a cutout groove. A base member for a shift lever is provided including a shaft section which is formed at its opposite ends with a pair of end projections. The end projections are rotatably disposed respectively inside the cylindrical portions of the bearing sections. Each end projection is generally oval-shape in cross-section so as to form two opposite end faces and two opposite side faces. The end faces are in sliding contact with the inner surface of the cylindrical portion of the bearing section.
