DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below by taking a vehicle steering lock device as an example. 1 is a longitudinal sectional view of a vehicle steering lock device, FIG. 2 is an exploded perspective view thereof,
FIG. 3 is a front view showing the electrical component unit in the LOCK position (the cover and the cover cap are omitted), and FIG. 4 is a front view showing the electrical component unit with the cover and the cover cap attached.

As shown in FIGS. 1 and 2, the steering lock device S is mounted on a steering column around a steering shaft via a mounting portion 1. An ignition switch 3 is provided at a rear end of a body 2 made of a hard resin material of the steering lock device S, and a cylinder lock 5 that is operated by a key 4 and operates the ignition switch 3 is housed inside. ing. A lock mechanism 6 is housed in the rear portion of the body 2 orthogonal to the cylinder lock 5, and the lock mechanism 6 can lock and unlock the steering shaft.

As shown in FIGS. 1 and 2, an electric component unit 7 is attached to the front portion of the key insertion portion of the steering lock device S, and a key insertion detection switch is provided in the electric component unit 7. Switch unit 8 including
And an illumination unit 26 for illuminating the position mark 16 are housed. The electrical unit 7 includes a donut-shaped printed circuit board 27, a resin case 9 that supports the printed circuit board 27, and a transparent resin cover that covers the front surface of the printed circuit board 27 and is fitted into the case 9. A movable member which is rotatably and laterally slidably guided by a U-shaped guide wall 11 formed on the case 9 and which operates a key insertion detection switch and the like. 12 and is housed in a metal cover cap 13 and attached to the front portion of the key insertion portion of the steering lock device S. 1 to 4
As shown in FIG. 3, the cover 10 is formed with protrusions 14 and 15 at portions corresponding to the respective positions, and the position marks 16 are printed on the back side of the protrusions 14 and 15 with a fluorescent paint. ing. On the other hand, cutout windows 28 and 29 are formed in the cover cap 13 so as to fit the protrusions 14 and 15 so that the position mark 16 can be visually recognized from the front. Further, the printed circuit board 27 is provided with light emitting diodes 17 and 18 at positions corresponding to the respective position marks 16. Therefore, when the light emitting diodes 17 and 18 are energized, the projections 14 and 15 of the cover 10 exposed from the cutout windows 28 and 29 are illuminated, and the position marks 16 shine to improve visibility at night. . Here, the electric component unit 7 is fixed by first temporarily engaging the hook groove 23 formed in the cover cap 13 with the engaging protrusion 24 formed in the body 2 and then driving a plurality of fastener pins 25. . By thus unitizing the lighting device, the structure is simplified and the workability of assembling the steering lock device S is also improved. A lead-out terminal 19 for connecting the power supply lines of the light-emitting diodes 17 and 18 and signal lines such as switches to a control circuit on the vehicle side is erected on the printed circuit board 27.
A coupler portion 20 is formed in the case 9 so that the lead-out terminal 19 can be fitted therein. Then, the coupler 22 at the tip of the lead wire 21 connected to the vehicle-side control circuit is connected to the coupler section 20. For this reason,
After the lighting device is assembled to the steering lock device S as described above, the coupler 22 at the tip of the lead wire 21 connected to the vehicle-side control circuit can be connected to the coupler unit 20 provided in the case 9. The workability of assembling the lighting device is further improved.

[0008]

As described above, according to the present invention, in the key switch in which the lighting device is provided around the key insertion hole, the lighting device is a printed circuit board on which a lighting circuit is mounted,
An illumination unit including a resin case that supports the printed circuit board, a transparent resin cover that covers the front surface of the printed circuit board, and a cover cap that accommodates the illumination unit and is fixed to the key switch body. A position mark is printed on the cover corresponding to each position of the key switch, a light emitting diode is arranged on the printed circuit board corresponding to the position mark, and the position mark is formed on the cover cap. A notched window is formed corresponding to the
Since the coupler part for deriving the power supply terminal of the bright circuit is provided , the lighting device is unitized, and as a result, the structure is simple and the assembling property to the key switch is improved. . Further, by providing the resin case with the coupler section for leading out the power supply terminal of the lighting circuit, the power cord can be connected to the coupler section after the key switch is assembled to the lighting device. Therefore, there is an excellent effect that the assembling property of the lighting device is further improved.
