FIG. 2 is a sectional view taken along the line A--A in FIG. 1. A horn 451 which emits a warning sound and serves as a horn sound source is mounted on a portion of the panel body 440 facing the vehicle rear side. I have. Also, the horn cover 45
0 constitutes the passage of the sound emitted from the horn 451, and the sound outlet side opening 452 opens toward the front side of the vehicle, and the cross-sectional area of the sound passage increases from the horn 451 toward the sound exit side. As described above, the panel body 440 is integrally formed with a portion facing the vehicle rear side.

In this embodiment, the wall portion 454 and the sound outlet side opening 452 constituting the sound passage (trumpet-like pipe) are formed integrally with the panel main body 440, and as shown in FIG. The horn cover 450 is formed by assembling and fixing a cover member 453 made of aluminum to the panel main body 440 from the rear side of the vehicle by welding, adhesive, or the like, thereby closing the sound passage (pipe).

Next, the features of this embodiment will be described.

In the present embodiment, the horn cover 450 constituting the sound passage (trumpet-like pipe) is connected to the panel body 4.
Since it is formed integrally with the horn 40, the number of parts and the number of manufacturing steps (man-hours for assembling) of the trumpet type horn can be reduced, and the trumpet type horn can be provided at low cost.

By the way, the conventional trumpet type horn (see FIG. 4) is mounted on the front side of the condenser or under the headlight, so that a failure or breakage due to a stepping stone or being wet easily occurs. In the present embodiment, the horn cover 450 constituting the sound passage (trumpet-like pipe) is formed integrally with the panel main body 440.
The design flexibility of the horn cover 450 is increased, and the horn 45
The mounting position of 1 can be a portion that is not easily scattered by rainwater, stepping stones, or the like. Therefore, the horn 451 can be easily protected from salt damage caused by snow-melting salt, seawater, or the like, while preventing damage due to flying obstacles such as stepping stones without providing a special sealing structure.

In this embodiment, the mounting position of the horn 451 which is hardly scattered by rainwater, stepping stones and the like is located on the rear side of the panel main body 440 and substantially at the center in the vertical direction. This is because the horn 451 is provided on the rear side of the panel body 440 to protect the horn 451 from rainwater, stepping stones, and the like in the vehicle running state, and the horn 451 is provided substantially at the center in the vertical direction. This is because the beam portions 410 and 420 function as eaves (eaves) to protect the horn 451 from rainwater falling from above and rainwater or flying stones scattered from below.

Since the sound outlet side opening 452 (sound outlet of the horn cover 450) is open toward the front of the vehicle, the warning sound is directed toward the front of the vehicle regardless of the mounting position of the horn 451. Can be emitted. Therefore, a warning sound of a sufficient volume can be obtained without raising the output of the horn 451 unnecessarily.

The tone of the warning sound is determined by the horn cover 45.
Specifications of 0 (pipe length, cross-sectional area and change rate of cross-sectional area, etc.)
Can be adjusted by changing.

(Second Embodiment) In the first embodiment, the sound outlet side opening 452 is orthogonal to the axial direction of the sound passage formed by the horn cover 450, so that the sound can be cut off. It is difficult to integrally mold the passage with resin. For this reason, in the first embodiment, as shown in FIG.
The cover member 453 was assembled to the horn cover 450 from a direction orthogonal to the axis of the sound passage to form a sound passage.

Note that the axial direction of the sound passage is a series of directions orthogonal to the cross section of the sound passage. In a so-called trumpet-type horn, the sound is indicated by a chain line (CL) in FIG. It is.

Accordingly, in the present embodiment, as shown in FIGS. 4 and 5, the sound outlet side opening 452 is opened in the axial direction of the sound passage formed by the horn cover 450. The side opening 452 faces downward.

Thus, as is clear from the schematic views of the dies 700 to 720 for the panel 400 shown in FIG. 6, the sound passage can be easily made of resin without attaching another member such as the cover member 453. It can be integrally molded. Incidentally, the mold 710 is a slide mold.

In the present embodiment, the sound outlet opening 452 is directed downward, but in the present embodiment, the sound outlet opening 452 is opened in the axial direction of the sound passage. Therefore, the sound outlet side opening 452 may be directed to the vehicle side or the upper side.

(Other Embodiments) In the above embodiment, the panel 400 is made of resin. However, the material of the panel 400 is not limited to resin, but may be other materials such as metal.

In the above-described embodiment, the horn cover 450 and the panel 400 are integrated by integrally molding them with a resin. However, after assembling them, the horn cover 450 and the panel 400 are integrally formed by joining means such as welding. You may. As is apparent from this modified example, the integral formation referred to in the present specification refers to the one integrally molded from a resin or the like at the time of molding, and the other parts are molded, then the parts are assembled and joined by welding or the like. It is meant to include one integrated by means.
