A fixed contact 64 that contacts the movable contact 60 in the D range and the ■ range, respectively, and a fixed contact 65 that contacts the movable contact 60 in the ■ range and the ■ range, respectively, on the lower side.
are arranged respectively.

Next, the operation of the device of the present invention will be explained. Operation 10 - The operating lever 2 is in the neutral position shown in FIG. 2, and the balls 4 supported at both ends of the shaft 15 are engaged with the notch 25 in the center of the detent block 3.

Now, in the case of ■ microwave, in Fig. 2, bin 1
When the operating lever 2 is tilted to the left about 7, the shaft 20 moves to the right against the spring 9a, and the position of the ■-■ range is selected. Next, when the operating lever 2 is tilted to the left (toward the front of the vehicle) about the shaft 20 in FIG. 3, the shift is made to the ■ range.

In the above operation, in the guide mechanism 50, the groove 30 of the select plate 6 is moved by the shift operation of the operating lever 2.
The relative position between the bottle 27a and the bottle 27a is such that the bottle 27a is in the neutral position 1if
It protrudes to the side of the select plate 6 along the groove 30 from fN, moves along the side wall 6a as the operating lever 2 is shifted, and reaches the (2) range.

On the other hand, the tip of the arm 33 fixedly supported on the shaft 20 moves to the right in FIG.
As shown by the arrow in the figure, the movable contact 60 of the block 56 connected via the protrusion 34 contacts the fixed contact 65 of the board 58 to close the circuit and select a desired travel mode.

To move the vehicle backward into the ■ range, select the operating lever 2 by tilting it to the right with the bin 17 as the center in FIG. 2, and then shifting by tilting it to the right in FIG. 3. At this time, the ball 4 engages with the notch 25 on the right side in FIG. 3, thereby regulating the inclination of the operating lever 2 about the shaft 20. In addition, select plate 6
The side wall 6b engages with the bin 27a in the range (1), and the inclination of the operating lever 2 about the bin 17 is restricted.

When returning the operating lever 2 to the neutral N range, first return the operating lever 2 about the shaft 20 to the point where the ball 4 engages with the notch 25 in the center of the detent 1-block 3 as shown in FIG. Since the shaft 20 is returned to the neutral position by the force of the spring 8.8a, the operating lever 2 is returned to the neutral position shown in FIG. 2 with the bin 17 as the center.

In this way, as shown in FIG. 8, by the select operation by tilting the control lever 2 around the bin 17 and the shift operation by tilting around the shaft 20, the predetermined fixed contacts 64, 65 are adjusted as shown in FIG. The movable contact 60 moves and can instruct a predetermined driving mode.

According to the present invention, in order to smoothly operate the operating lever 2 from the ■ range to the ■ range, as shown in FIG. A sloped wall 53 is provided by cutting, and a sloped wall 52 is provided by cutting diagonally at the intersection of the partition groove 30 and the groove 51. As a result, the bin 27a can be smoothly moved relative to the select plate 6 from the ■ range to the ■ range.

In addition, in the case of range (2), when the shaft 20 moves to the left in FIG. 2, the inclined surface 9b of the grooved roller 9 is steeper than the inclined surface 9a, so Since the resistance force of the ball 39 is large, this sense of resistance can alert the driver to the gear shifting operation to the ■ range.

13-Furthermore, according to the present invention, the blocks 1 to 3 that regulate the shift position of the operating lever 2 are made of synthetic resin made of a low-friction material, and are supported by both side walls of the base frame. The engagement with the ball 4 is extremely smooth,
And since the balls 4 are arranged at both ends of the shaft 15, the shaft 1
The effect is that the load on the detent block 3 received from the shaft 15 is halved, the load acting on the shaft 15 is balanced, and the load is smoothly guided along the opening 26.

Since the present invention is configured as described above, the switch for selecting the shift position or driving mode of the automatic transmission can be operated in the same way as in a manual transmission by tilting the control lever left and right and forward and backward. There is no need to look at the switch while driving, and driving safety can be ensured. In addition, since the operating lever 2 is supported by the pin 17 with respect to the second shaft 15, the inclination of tilting the operating lever 2 to the left or right can be arbitrarily increased compared to the case where the operating lever 2 is tilted forward or backward. can be further improved. Furthermore, since the 14-switch 1o is constructed as a single unit and separate from the operating mechanism, its quality control is easy, and it is also excellent in that it is easy to assemble and does not require special adjustment.

It goes without saying that the present invention can also be applied to a shift control lever device for remote control of a transmission operated by a fluid pressure actuator.
