In the keyhole illumination device, a groove is formed in a part of the rotation stop projection provided on the outside of the rotor case, and the locking leg is engaged with the groove.

The present invention will be described in detail below based on embodiments shown in the accompanying drawings.

In the first actual fan example shown in FIGS. 4 to 7, the keyhole illumination device S is located at the outer side end 22a of the rotor case 22.
K-covering cup (-23), a light-transmitting member 24 disposed between the outside end 22a of the rotor case 22 and the cup 23, and a light emitting diode 25 as a light source comprising a lead wire 35. It is configured.

The rotor case 22 has a substantially cylindrical rotor housing section 21.
and a flange 31 integrally formed coaxially with the rotor housing portion 21 at the outer side edge of the rotor housing portion 210;
Upper and lower anti-rotation protrusions 26A integrally formed on the peripheral wall of the rotor storage portion 21 on the interior side of the flange 31
and a locking protrusion 26B of the retaining clip 10.
The rotor 1 is housed so that a is exposed at the open end of the rotor case 22 on the outside of the vehicle. The upper projection of the locking projections 26A is used to position the rotor case 22 in the rotating direction, and the lower locking projection is also formed to be long in the axial direction of the rotor case 22. A substantially rectangular groove 27 is formed from the outer surface of the flange 31 along the axial direction of the rotor case 22, and a notch 33 is formed on the outer surface of both side walls of the projection 26A along the axial direction. ing. Further, a slit 39 is formed between the locking protrusion 26B and the rear surface of the flange 31 so that the retaining clip 10 is engaged therewith.

- Still, the light-transmitting member 24 is a transparent member such as acrylic resin formed in a substantially truncated cone shape, and an illumination hole 30 having substantially the same diameter as the keyhole surface 1a of the rotor 1 is provided in the center thereof. is opened, and a locking leg portion 29 extending toward the interior of the vehicle is integrally formed on the peripheral edge of the light-transmitting member 240. This locking leg portion 29 is formed to have a substantially rectangular cross section, and a light emitting diode 25 as a light source is embedded in the tip thereof, and a lead wire 35 extending from the light emitting diode 25 is connected to a power source. connector (not shown) is connected. The locking leg portion 29 engages with the groove 27 of the rotor case 22, and the notch 33 of the eel hatch protrusion 26A
A clip 3 having a substantially U-shaped cross section and having a claw 34a that engages with the clip 3.
4, the light transmitting member 24 is inserted into the rotor case 22 so as to closely fit against the outer side end 22a of the rotor case 22.

Further, the upper rudder cover blade is a substantially camp-shaped metal member, and a key insertion hole 37 having approximately the same diameter as the illumination hole 30 of the light-transmitting member 24 is opened in the center thereof, and the outer periphery thereof is located on the inside. The above-mentioned cover is bent at this bending part 3.
2 to the seven runciers 31 of the rotor case 22 to fully sandwich the light-transmitting member 24.
It is fixed at 2.

Therefore, when assembling the keyhole illumination device according to this embodiment, as shown in FIGS. The light member 24 and cover 23 are assembled in advance. At this time, as shown in FIG. 6, the rotor 1, the rotor case 22, the transparent member 24, and the cover 23 are arranged coaxially, and as shown in FIG. 22 and the center of the cover 23. Further, the locking leg portion 29 provided on the light-transmitting member 24 is as shown in FIGS. 5 and 6.
Since it is engaged in the groove 27 of the locking protrusion 26A of the rotor case 22 and held by the clip 34, the locking leg 29 becomes a new (external protrusion) relative to the rotor case 22. ) The light-transmitting member 24 is the rotor case 2
It is installed in a state where it is prevented from rotating relative to 2. The locking leg portion 29 serves as a mounting portion for the light emitting diode 25 and also serves as a path for guiding light from the light emitting diode 25 to the light transmitting member 24. Therefore, it is no longer necessary to protrude and provide the lamp storage section 9 outside the rotor storage section 8 as in the conventional case, and the rotor case 22 becomes smaller than that in the conventional case.

Next, as shown in FIG. 6, when attaching the pre-assembled item to the door panel 19, the rotation stop notch 41 and the rotation stop protrusion of the rotor case 22 are inserted into the mounting hole 40 opened in the door panel 19. Insert the rotor case 22 while engaging the protrusion 26B and the flange 3.
1 Tinging knob 1 in the slit 39 between the rear surface
The rotor case 22 may be fixed by engaging the rotor case 22.

At this time, the light emitting diode 25 is connected to the light transmitting member 24 in advance.
Since the light emitting diode 25 is embedded in the locking leg 29 provided in the rotor case 22, there is no need to worry about the light emitting diode 25 being damaged. In comparison, the working process of the keyhole illumination device S is simplified. In addition, since the connection to the power supply side is made through a connector (not shown) of the IJ + lead wire 35, it is possible to adjust the length of the lead wire 35 so that connection work can be done in a wide area. You can work more easily and improve work efficiency.

According to the keyhole illumination device S assembled in this way, when the key Kt is inserted at night or the like, the light emitting diode 25 is caused to emit light by a switch not shown, and the light emitting diode 25 emits light. The irradiated light is emitted from the locking leg portion 29 through the light-transmitting member 24 and from the illumination hole 30, and illuminates the keyhole surface 1ak of the rotor 1. In this case, since the light-transmitting member 24 has a substantially truncated cone shape, the light passing through the locking member 29 is reflected by the conical surface 28, and the reflected light is further diffused by the conical surface 28 to effectively achieve the above-mentioned effect. Lighting hole 3
It is designed to focus on 0. In addition, the light transmitting member 2
4 is shielded by a metal cover 23,
Not only does no light leak outside of the illumination hole 30, but the light is reflected inward from the cover 23 and is more effectively focused on the illumination hole 30.

Next, a second embodiment shown in FIG. 8 will be described. The keyhole illumination device S according to this embodiment is constructed in substantially the same manner as the first embodiment, but has a light emitting diode 25 embedded in a translucent member 24 having a substantially truncated conical shape. A lead wire 35 of the light emitting diode 25 extending therefrom is formed as a locking leg portion 29. In addition, the light transmitting member 2
A concave portion 42 is formed in the light-transmitting member 24 as a rotation stopper of No. 4, and a pin 43 that engages with the concave portion 42 is formed protruding from the rotor case 22 side.

Therefore, according to the second embodiment, the rotor 1, the transparent member 24, and the cover 23 are assembled in advance to the rotor case 22 in the same machine as the first embodiment, and then attached to the door panel 19. At this time, the lead wire 35 as the locking leg 29
is housed in #27 of the rotor case 22 and is held by the clip 34, so there is no risk of the lead wire 35 being damaged by the edges of the mounting JLItlo. Other effects are the same as in the first embodiment.

Incidentally, in each of the above embodiments, the key illumination device S for a lock attached to the door panel 19 has been described, but the key illumination device S is not necessarily limited to this, and for example,
Of course, the present invention can also be applied to a lock built into an escutcheon to which a door out-sight nondle is assembled, a trunk lid lock, an ignition key, etc.

As described above, according to the keyhole illumination device according to the present invention, a light source is pre-assembled to a part of the light-transmitting member, and the light-transmitting member is provided with a locking leg connected to the light source. On the other hand, a groove is formed on a part of the rotation stopper protrusion provided on the outside of the rotor case, and the above-mentioned locking leg is held in the groove, so compared to the conventional structure, rotor case,
It is possible to downsize the cover that covers the light-shielding member and the light-transmitting member, and the keyhole illumination device can be made compact accordingly.The rotor case is also a type that does not have a keyhole illumination device. Because it can be shared with the
There is no need to change the mounting hole on the vehicle body depending on the individual.
Accordingly, the keyhole illumination device can be applied over a wide range of areas. Further, according to the present invention, since the key hole can be located in the center of the cover, the quality of foreign bonds can be kept good, and furthermore, the light source can be assembled in advance to the transparent member. When assembling the lock to the vehicle body, the above-mentioned work of installing the light is no longer necessary, and there is no concern that the light source will be damaged, and the work efficiency of assembling the keyhole illumination device can be improved. .
