Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of a hollow body formed by closing a front opening of a housing with a lens.

[0002]

2. Description of the Related Art Conventionally, for example, as shown in FIG. 6 (A), a rear combination lamp 3 provided on the left and right rear portions of a vehicle body 1 is attached to a trunk lid 2 for opening and closing a trunk room (not shown) in the rear portion of the vehicle body 1. , 3 are provided with a finisher 4 as a hollow body in order to provide a sense of unity with the lens 3a.

As shown in FIG. 5, the finisher 4 includes a housing 5 having a front opening 5a and a front opening 5a.
A lens 6 for closing a and a packing 7 attached to the housing 5 are provided, and in the assembled state, they are fixed to the trunk lid 2 via fixing means 8 such as bolts.

A holding portion 5b having a substantially U-shaped cross section which opens in the same direction as the front opening 5a is formed in the housing 5 along the front opening 5a. Further, a plurality of engagement holes 5c (only one position is shown in FIG. 5) are formed in the outer wall portion of the holding portion 5b.

The lens 6 is formed with a leg portion 6a which is inserted into the holding portion 5b. Further, a plurality of lances 6b (only one position is shown in FIG. 5) that engage with the engagement holes 5c are formed on the outer wall surface of the leg portion 6a.

With respect to the housing 5 and the lens 6, the lance 6b is engaged with the engaging hole 5 while the leg portion 6a is inserted into the holding portion 5b.
The lens 6 is fixed to the housing 5 in a hermetically sealed state by the sealing material 9 which is positioned by engaging with c and is filled in the holding portion 5b.

[0007]

By the way, in the hollow body mating portion structure constructed as described above, the plurality of engaging holes 5c are formed on the outer wall surface of the holding portion 5b.
When the trunk lid 2 is rotated from the trunk room closed state shown by the solid line in FIG. 6 (A) to the trunk room open state shown by the two-dot chain line in FIG. 6 (A),
As shown in (B), there is a problem that the engagement hole 5c is visible and the appearance is spoiled. Actually, not only the engaging hole 5c but also the lance 6b and the sealing material 9 protruding from the gap between the engaging holes 5c can be seen at the same time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hollow body joining portion structure capable of improving the appearance.

[0009]

In order to achieve the object, the present invention provides a hollow body joining portion structure formed by closing a front opening of a housing with a lens.
A holding portion having an engaging hole in the bottom wall portion and opening in the same direction as the front opening is formed in the housing along the front opening, and a rib surrounding the engaging hole is formed. A leg portion protruding from the back surface of the bottom wall portion and inserted into the holding portion is formed on the lens, and a lance that engages with the engagement hole is formed at a tip of the leg portion so as to face the inside of the rib. The gist is that a sealing material covering from the tip of the leg portion to the lance is filled from the inside of the holding portion to the inside of the rib.

[0010]

With such a structure, in the structure of the mating portion which forms the hollow body by closing the front opening of the housing with the lens, the housing has the engaging hole in the bottom wall and the front opening. A holding portion having a substantially U-shaped cross section that opens in the same direction is formed along the front opening, a rib surrounding the engaging hole is projected on the back surface of the bottom wall portion, and a leg portion that is inserted into the holding portion is provided on the lens. Is formed, a lance that engages with the engaging hole is formed at the tip of the leg so as to face the inside of the rib, and a sealing material that covers from the tip of the leg to the lance extends over both the holding portion and the rib. Is filled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the structure for joining hollow bodies according to the present invention is applied to a rear finisher for a vehicle as shown in FIGS.
It will be described based on.

In FIG. 4A, a trunk lid 1 for opening and closing a trunk room (not shown) at the rear of the vehicle body 11.
2, a finisher 14 as a hollow body is provided in order to give a feeling of unity with the rear combination lamps 13, 13 provided on the left and right rear portions of the vehicle body 11 and the lens 13a.

As shown in FIG. 1, the finisher 14 includes a housing 15 having a front opening 15a, a lens 16 that closes the front opening 15a, and a packing 17 attached to the housing 15, and these are assembled. In this state, it is fixed to the trunk lid 12 via fixing means 18 such as bolts.

The housing 15 has a holding portion 15b having a substantially U-shaped cross section which opens in the same direction as the front opening 15a.
It is formed along 5a. Further, as shown in FIG. 2, a plurality of engagement holes 15d (only one location is shown in FIGS. 1 and 2) are formed in the bottom wall portion 15c of the holding portion 15b. Further, a rib 15e is projected on the back surface of the bottom wall portion 15c so as to surround the engagement hole 15d. Rib 15
The shape of e is not particularly limited, such as the circle shown in FIG. 3 (A) and the rectangle shown in FIG. 3 (B).

The lens 16 is formed with a leg portion 16a into which a tip portion is inserted in a holding portion 15b. Also, the legs 16
At the tip of a, the engaging hole 15
A plurality of lances 16b outwardly hung so as to engage with d (only one position is shown in FIGS. 1 and 2)
Are formed to project. In addition, this engagement state is the holding portion 1
The seal member 19 filled from 5b through the engagement hole 15d to the inside of the rib 15e prevents backlash from occurring, thus ensuring reliability. Further, the sealing material 19 that extends over the surface ensures the hermeticity.

In the above structure, the housing 15 and the lens 16 are positioned by inserting the leg 16a into the holding portion 15b and engaging the lance 16b with the engaging hole 15d, and the housing 15 and the lens 16 are filled in the holding portion 15b. Sealing material 1
It is fixed in a sealed state by 9.

The housing 15 and the lens 16 thus combined are fixed to the trunk lid 12 by the fixing means 18 with the packing 17 attached. At this time, the rib 15e plays a role of a contact rib for determining the distance between the trunk lid 12 and the finisher 14 by abutting the tip of the rib 15e on the trunk lid 12.

Incidentally, the rib 15e is circumferentially continuous with the outer wall portion of the holding portion 15b so that the rib 15e is adjacent to the rib 15e.
There is no gap between the trunk lid 12 and the holding portion 15b.

By the way, in the above embodiment, the hollow body of the present invention is applied to the finisher mounted on the rear portion of the vehicle body, but it may be applied to a vehicular lamp in which the housing 15 is equipped with a bulb.

[0020]

As described above, in the structure for joining parts of the hollow body of the present invention, the bottom wall has an engaging hole and has a substantially U-shaped cross section which opens in the same direction as the front opening. The holding portion is formed in the housing along the front opening, the rib surrounding the engaging hole is projected from the back surface of the bottom wall portion, the leg portion inserted into the holding portion is formed on the lens, and the rib is engaged so as to face the rib. A lance that engages with the dowel is formed at the tip of the leg, and a sealing material that covers from the tip of the leg to the lance is filled from the inside of the holding portion to the inside of the rib to improve the appearance. it can.
