Further, on the back surface side of the H-shaped contact 68 of the substrate 44, a retaining member 72 is fixed to the switch knob 70 with enough margin that the H-shaped contact 68 can move up and down in the long hole 66. The retaining member 72 is covered with a retainer 74 fixed to the substrate 44, thereby forming a parking position detection switch 76.

FIG. 6 is a cross-sectional view of the shift lever device 10. The shift lever 16 includes a pipe 9 fixed to a shaft 92 rotatably supported by the shift lever device main body 12.
The detent rod 98 is slidably supported in a pipe 94 by a spring 96 having one end fixed to a shaft 92. Furthermore, the detent rod 9

The connect pin 100 is connected to the parking position detection switch 7.
6 is connected to the switch knob 70. When the shift lever 16 moves, both ends of the pin 102 move along a cam (not shown), and the movement of the pin 102 causes the detent rod 98 to move the pipe 9.
4, the connection pin 100 moves the switch knob 70 of the parking position detection switch 76.

Next, the assembling process of the shift lever device based on the above configuration will be described. As shown in FIG. 1 for explaining the connection state of each member, an overdrive switch 101, a night illumination lamp 100, a parking position detection switch 58, the shift lock solenoid 48 is assembled to the shift lever device main body 12, and the ECU board 36 is further assembled to the shift lever device main body 12.

01a, and the night illumination lamp 10
0 connector 100a. Then, the shift lever device main body 12 is assembled to the vehicle body, and the connector 46 of the board 44 is connected to the connector 47 of the vehicle body.

In the above assembling step in the present embodiment, the connector 101 of the overdrive switch 101 is used.
a and the connector 100a of the night illumination lamp 100
4, the connector 46 of the board 44 is connected to the connector 47 of the vehicle body, and the connection between the overdrive switch 101 and the night lighting lamp 100 is performed via the board 44. Since the connection of the main body 12 to the vehicle body after the assembly is sufficient, the connection between the connector 46 of the board 44 and the connector 47 on the vehicle body side is sufficient, so that the assembly efficiency is improved.

In the above configuration, when the ignition key 88 is turned on, power is supplied to the board 44 and each part. When the shift lever 16 is moved to the parking position, the ECU mounted on the board 44 Move along a cam (not shown), and the detent rod 98 moves inside the pipe 94. Then, by the movement of the detent rod 98, the connect pin 100 moves the switch knob 70 of the parking position detection switch 76 upward.

Then, the contact pattern 64a of the parking position detection switch 76 shown in FIGS. 3 and 4 is connected to the contacts 68a and 68b of the contact 68, and the contact pattern 64b is connected to the contact 68c. Thereby, the parking position detection switch 76 detects the parking position, and drives the shift lock means 22 of FIG. 10 to release the shift lock of the shift lever 16 when the ignition is on and the brake is depressed. Then, the shift lock solenoid 48 in FIG. 10 is energized, and the iron core of the shift lock solenoid 48 moves leftward, whereby the link 52 also moves leftward. Further, the movement of the link 52 to the left causes the link 5 to move.
The stopper 54 engaged with the lever 2 swings counterclockwise (see FIG. 11), the stopper 54 is separated from the shift lock plate 56, and the parking position lock of the shift lever 16 is released. When the release button 60 (see FIG. 7) is pressed even during the shift lock, the shift lock is released only while the release button 60 is pressed, and the shift lever 16 can be moved to another position.

When the shift lever 16 is moved to, for example, the D range while the release button 60 is being pressed, the pin 102 moves along a cam (not shown), and the detent rod 98 moves in the pipe 94 in the direction of arrow D1. .
Then, the connect pin 100 moves the switch knob 70 of the parking position detection switch 76 in the direction of arrow D1 by the movement of the detent rod 98 in the direction of arrow D1.
Then, the contact pattern 64a of the parking position detection switch 76 and the contacts 68a, 68b of the contact 68
And the contact pattern 64b and the contact 6
8c is disconnected, the contact pattern 64c and the contact 68d are connected, and the parking position detection switch 76
Detects that the vehicle is not at the parking position, and opens the shift lock means 22.

Then, the shift lock solenoid 48 is energized, the iron core of the shift lock solenoid 48 moves, and the link 52 also moves. Further, the stopper 5 engaged with the link 52 by the movement of the link 52
4 swings counterclockwise (see FIG. 11), and the stopper 54
Moves from the position where the shift lock plate 56 is prevented from moving, and the shift lever 16 is unlocked.

In the state where the contact pattern 64a is connected to the contacts 68a and 68b of the contact 68, the contact pattern 64b is connected to the contact 68c, and the contact pattern 64c is connected to the contact 68d,
The parking position detection switch 76 detects that the vehicle is not at the parking position.

When the ignition key switch 82 is turned on, or the ACC position and the shift lever 16 are in the parking position, the solenoid 86 is operated in the same manner as in the prior art shown in FIG.
Is turned on to lock the ignition key 88 with the lock pin 90 so that the ignition key 88 does not come off.

In the above-described embodiment, the board 44 is directly fixed to the shift lever device main body 12 with screws. However, the present invention is not limited to this, and as shown in FIG.
The board 44 may be fixed to the split case 78 forming a part of the system lever device body in a state where the board 44 covers the ECU side of the substrate and is detachably attached to the shift lever device body 12. In this way, the assembling workability and the maintainability are improved, and further, when the driver spills a drink such as coffee on the shift lever device 10, it is possible to prevent the coffee from splashing on the substrate 44, and to provide waterproof and dustproof properties. Can be improved. In such a case, the parking position detection switch is disposed at a position as shown in FIG.

Since the substrate 44 is located below the position indicator 20, even if coffee enters the shift lever device main body 12 through the gap between the elongated hole 14a and the slide cover 18, the coffee may be applied to the substrate 44. There is no. Further, since the connector 46 directly connected to the terminal 44a of the board 44 is disposed downward and inclined at a predetermined angle θ, even if coffee or the like is applied, the connector 46 is immediately drained to prevent a short circuit or the like. To prevent.

In the above embodiment, the pin 102
Are arranged so that both ends thereof move along a cam (not shown) when the shift lever 16 moves.
02 may move along the cam when the shift lever 16 moves. In this case, the side of the pin 102 that does not contact the cam can be used as a connect pin.

Further, in the above embodiment, the case where the connector for the overdrive switch, the connector for the night illumination lamp, the connector for the parking position detection switch, and the connector for the shift lock solenoid are separately provided has been described. It is also conceivable to construct a single connector as a single unit, connect the overdrive switch, night illumination lamp, parking position detection switch, shift lock solenoid to the connector, and then connect the connector to the board. According to this configuration, since only one connector needs to be connected to the board, assembly is facilitated.

As described above, according to the present invention,
After assembling the shift lever device to the vehicle body side, it is only necessary to connect only the board and the vehicle body side, so the number of wiring can be reduced
The assembly workability is improved.
