2. Description of the Related Art A headlamp switch and a rear fog lamp switch which are rotatable around the axis of the turn signal switch are provided at the tip of a turn signal switch of an automobile, for example. By rotating the headlamp switch, the headlamp is lit, and by rotating the rear fog lamp switch, the rear fog lamp is illuminated. (Nissan Motor Co., Ltd., issued in August 1997, "New vehicle description WC34-1 ", page F-4).

There is a legal requirement that the rear fog lamp be turned on only when the headlamp is turned on. That is, the lighting of the rear fog lamp alone is prohibited, and only the lighting with the head lamp is permitted.

For this reason, conventionally, a control unit for preventing the rear fog lamp from turning on when the head lamp is not turned on even if the rear fog lamp switch is operated is provided.

[0005]

However, in such a conventional technique, it is necessary to add a control unit for preventing the rear fog lamp from being lit alone in the lamp electronic circuit. Is complicated, and the cost is disadvantageous.

The present invention has been made by paying attention to such a conventional technique, and provides a rear fog lamp switch structure which can prevent the rear fog lamp from being lit alone without adding a control unit. is there.

[0007]

According to the first aspect of the present invention,
A switch body is provided with a headlamp switch and a rear fog lamp switch that are each rotatable around the axis of the switch body, and the rear fog lamp switch is slidably supported along the axis toward the headlamp switch side, A first concave / convex means is provided between the rear fog lamp switch and the head lamp switch, which allows the rear fog lamp switch to slide only when the head lamp switch is turned on, and allows the rotation of only the rotation operation range of the rear fog lamp switch, A second concave / convex means is provided between the switch body and the rear fog light switch to prevent rotation of the rear fog light switch when the rear fog light switch is not slid and to allow rotation of the rear fog light switch when the rear fog light switch is slid.

According to the first aspect of the present invention, the prevention of single lighting of the rear fog lamp is achieved by a mechanical structure. That is, only when the headlamp switch is turned to the lighting side, the rear fog lamp switch can be slid and turned to the lighting side, so in order to turn on the rear fog lamp, the headlamp must be turned on. That is, the single lighting of the rear fog lamp is prevented.

Further, since the first concave / convex means permits rotation only in the rotation operation range of the rear fog lamp switch, reliable rotation operation of the rear fog lamp switch is ensured, and the head lamp switch is rotated to the non-lighting side. In this case, the rear fog lamp switch also rotates to the non-lighting side, so that only the rear fog lamp does not remain in the lighting state.

[0010] According to a second aspect of the present invention, the second unevenness means includes:
The arrangement is such that when the rear fog lamp switch is slid and rotated to the lighting side, the rear fog lamp switch is prevented from returning in the non-sliding direction.

According to the second aspect of the present invention, the arrangement of the second unevenness means prevents the rear fog lamp switch in the lit state from returning in the non-sliding direction, so that the lit state of the rear fog lamp is reliably maintained. Is done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes a turn signal switch as a “switch body”. At the tip of the turn signal switch 1, a head lamp switch 2 and a rear fog lamp switch 3 are mounted so as to be rotatable about an axis S of the turn signal switch 1. The rear fog lamp switch 3 has a structure that can slide toward the head lamp switch 2 along the axis S. Furthermore, between the headlamp switch 2 and the rear fog lamp switch 3, the turn signal switch 1 is integrated,
A non-rotating origin display section 4 is provided.

A part of the headlamp switch 2 includes a support shaft 5
Is formed as a rotating plate 6 that rotates integrally with the rotating plate 6.
The rotary plate 6 has a first recess 7 having a size corresponding to the rotation operation range of the rear fog lamp switch 3.

Inside the rear fog lamp switch 3, there is formed a first convex portion 8 which can be engaged with the first concave portion 7. The first convex portion 8 can move within the first concave portion 7 within a range where the rotation operation of the rear fog lamp switch 3 is enabled. A projection 9 formed on the opposite side of the first projection 8
Engages with the internal operation plate 10 to rotate the operation plate 10 integrally. The rotation of the operation plate 10 switches ON / OFF of the rear fog lamp. Then, the first concave portion 7 and the first convex portion 8 form the “first concave / convex section” of this embodiment.

In the peripheral edge of the other end of the rear fog lamp switch 3, three second concave portions 11 are formed at predetermined intervals. In the corresponding portion of the turn signal switch 1, three second convex portions 12 that can be engaged with the second concave portion 11 are formed. The second recess 11 and the second
The "second unevenness means" of this embodiment is formed from the convex portion 12, and the rear fog lamp switch 3
Is prevented from rotating. The rear fog light switch 3
Is disengaged from the second concave portion 11 and the second convex portion 12, the rear fog lamp switch 3 can be rotated.

Next, how to use this switch will be described with reference to FIGS.
Explanation will be given based on FIG. When the headlamp switch 2 is not rotated (see FIG. 3), the rear fog lamp switch 3 is prevented from sliding because the first projection 8 hits a portion other than the first recess 7 of the headlamp switch 2. The engagement between the second convex portion 12 and the second concave portion 11 is maintained, and the rotation of the rear fog lamp switch 3 is prevented. Therefore, even if the driver touches the rear fog lamp switch 3 when operating the turn signal switch 1, the rear fog lamp switch 3 does not accidentally rotate.

To turn on the headlamp, the headlamp switch 2 may be turned in the lighting direction. When the head lamp switch 2 is turned to the lighting position, the first recess 7 matches the first projection 8 (see FIG. 4), so that the rear fog lamp switch 3 can slide.

When the rear fog lamp switch 3 is slid, the first projection 8 engages in the first recess 7 and
The engagement between the second convex portion 12 and the second concave portion 11 is released (see FIG. 5). Then, the first convex portion 8 in the first concave portion 7 is
Since the size of the concave portion 7 corresponds to the rotation operation range of the rear fog lamp switch 3, the rear fog lamp switch 3 can be surely rotated to the lighting position and the rear fog lamp can be turned on (see FIG. 6). In this state, since the second convex portion 12 and the second concave portion 11 have a positional relationship of interfering with each other, the rear fog lamp switch 3
, The rear fog lamp switch 3 does not return in the non-sliding direction, and the lighting state of the rear fog lamp is reliably maintained.

As described above, in this embodiment, the rear fog lamp switch 3 can be slid and rotated to the lighting side only when the head lamp switch 2 is rotated to the lighting side. Must always be in a state where the headlamp is turned on, and the single lighting of the rear fog lamp is reliably prevented.

Finally, when the headlamp switch 2 is turned to the non-lighting side, the rear fog lamp switch 3 also rotates together with the non-lighting side due to the engagement relationship between the first convex portion 8 and the first concave portion 7. Only the rear fog lamp does not remain lit.

In this embodiment, the turn signal switch 1 is taken as an example of the "switch body", but the present invention is not limited to this.
