Each part is grouped into several units. Specifically, a board 7 on which the parking position detection switch 70 as a detection switch unit, a control unit, a connector, etc. are mounted.
2 is housed in the board housing case 74 and assembled to the shift lever device main body 52.

[0006]

However, when the parking position detection switch 70 is assembled to the board 72,
When the substrate 72 is stored in the substrate storage case 74, it is fixed by engaging claws, screws 76, etc., which are not shown,
Further, the unitized substrate storage case 74 is assembled to the shift lever device main body 52 by engaging claws and screws. Generally, since each part has a shape error, when assembling the parking position detection switch 70 and the board 72, assembling the board 72 and the board storage case 74, and further, the board storage case 74 and the shift lever device. Assembling errors occur when assembling the main body 52, and the assembling errors are superimposed in each assembling process, so that the switch knob 7 of the parking position detecting switch 70 can be manufactured.
0a and the connecting pin 66 on the shift lever device main body 52 side are not properly engaged with each other.
As a result, there are problems that the alignment becomes complicated and the assembly process becomes troublesome, and the accuracy and reliability of the parking position detection switch deteriorate.

The present invention has been made in order to solve the above problems, and improves the position detection accuracy and reliability, and makes it possible to easily assemble the shift lever device. And its assembling method.

Since the structure of the shift lever device main body is similar to that of the conventional example shown in FIG. 7, the description thereof will be omitted, and the description will focus on the assembly portion of the parking position detecting switch.

As shown in FIG. 1, the parking position detecting switch 10 has a switch knob 12 on one surface side, and further has a first position for positioning the parking position detecting switch 10.
Pipe-shaped engaging pins 14a and 14b having engaging holes at one end are formed as engaging members. Further, on the other surface side of the parking position detection switch 10, there are formed loose fitting claws 20a to 20d which can be loosely fitted in the substrate openings 18a to 18d as the first temporary holding means formed on the substrate 16. When the parking position detection switch 10 is mounted on the board 16, the size of the board openings 18a to 18d is larger than the size of the loose fitting claws 20a to 20d in the vertical direction. It is held so that it can move up and down. In addition, since the loose fitting claws 20a to 20d have the bent hooking portions, the board 1 is not attached when mounted.
It is designed so that it does not fall off easily from 6. Further, the board 16 is formed with engaging holes 22a and 22b as first engaging elements for positioning the board 16. In addition to the parking position detection switch 10,
Various control elements (collectively ECUs), connectors 24, etc. are mounted, and the terminal 10a of the parking position detection switch 10 is electrically connected to a predetermined terminal of the substrate 16 via a lead wire or the like.

FIG. 2A shows a board housing case 26 for housing the board 16 in which the parking position detecting switch 10 is loosely fitted. The substrate storage case 26 has, on its inner wall surface, grip claws 28 (two on each of the opposite wall surfaces in this embodiment) as second temporary holding means for slidably gripping both ends of the board 16. The grip claw 28 is
As shown in FIG. 2B, the substrate 16 has a gripping width such that it can be slidably gripped in the vertical direction (the direction of arrow A in the drawing). If the grip claw 28 is formed to have a low height, the substrate 1
The substrate 16 can be held in the substrate storage case 26 by slightly bending the substrate 6. In this way, in the temporary holding state of the parking position detection switch 10 and the substrate 16,
Assembly of the detection switch unit is completed.

FIG. 3 shows a side plate 30 integrally or separately provided on the shift lever device main body. Positioning and fixing means are formed on the side plate 30. That is, the switch positioning pins 32a and 32b having cylindrical protrusions at the tips are formed as the second engaging elements that can be engaged with the engaging pins 14a and 14b that are the first engaging elements of the parking position detection switch 10. . The switch positioning pins 32a and 32b are formed at positions where the parking position detection switch 10 can be fixed to the side plate 30 at appropriate positions. In addition, the switch positioning pin 32a,
Substrate positioning pins 34a, 34b having cylindrical protrusions at the tips as second engaging elements engageable with the engaging holes 22a, 22b which are the first engaging elements of the substrate 16 in the vicinity of 32b.
Are formed. These board positioning pins 34a, 34
b is also formed at a position where the substrate 16 can be fixed to the side plate 30 at an appropriate position. Further, the side plate 30 is formed with a boss 38 for fixing the flange 36 formed on the substrate housing case 26 with a screw or the like.

When the detection switch unit is combined with the side plate 30 constructed as described above, the parking position detection switch 10 is connected to the board openings 18a to 18a as shown in FIG.
18d and the board 16 is movably held by the grip claws 28, so that the parking position detection switch 10 and the board are detected by the switch positioning pins 32a and 32b and the board positioning pins 34a and 34b formed on the side plate 30. 16 is positioned at a predetermined position, and by fixing the board storage case 26 to the side plate 30 with screws 42 or the like, the parking position detection switch 10 and the board 16 are fixed at accurate positions. That is, the parking position detection switch 10 transmits the movement of the connect pin 66 formed on the shift lever 54 to the plate 4

In addition, the parking position detection switch 1
The same applies when only 0 is held by loose fitting.

Also, an example is shown in which the tip ends of the switch positioning pins 32a and 32b and the substrate positioning pins 34a and 34b as the second engaging elements formed on the side plate 30 have cylindrical protrusions. As shown in FIG. If the switch positioning pins 44a and 44b and the board positioning pins 46a and 46b each having a tapered shape are used, positioning work of the parking position detection switch 10 and the board 16 at the time of combination can be further facilitated.

Further, in this embodiment, the first engaging element formed on the parking position detecting switch 10 and the board 16 is a hole-shaped engaging element, and the second engaging element formed on the side plate 30 is a pin-shaped engaging element. As described above, the same effect can be obtained even when the first engaging element has a pin shape and the second engaging element has a hole shape.

Further, although the present embodiment has been described by using the grip claw 28 as the second temporary holding means, this shape is not limited to this, and a similar effect can be obtained even with a long groove structure.

According to the second and fifth aspects of the present invention, an assembly error that occurs when the parking position detection switch and the board are combined is absorbed by the loose fitting engagement or the sliding engagement, and the parking is performed according to the shift lever device main body. Since the position detection switch can be accurately fixed at a predetermined position, the position detection accuracy and reliability of the parking position detection switch can be improved.

According to the third and fourth aspects of the present invention, the parking position detecting switch and the board can be finally positioned by the combination of the engaging elements, so that the side plate and the parking position detecting switch are combined. The positioning can be easily performed. Therefore, the shift lever device can be easily assembled. Furthermore, by making the engagement element tapered, the assembly efficiency can be further improved.
