外側に周設された外枠である。B. Prior Art The conventional structure of the joint between the lamp body and the lens will be described with reference to a cross-sectional view of the main parts shown in Figure 2. 4 is a welded frame provided around the outer periphery of a reflective surface (not shown) of the lamp body 1 toward the lens side; 5 is a welded frame integrally connected to the periphery of the lamp body 1; 6 is a lens; 7 is a welding foot that contacts the welding frame 4 provided around the lens 6 toward the lamp body 1; This is an outer frame that faces toward the lamp body 1 and is provided around the outside of the welding foot 7.

われている。 In addition, the lamp body 1 and the lens 6 are joined by hot plate welding at the abutting parts of the welding frame 4 and the welding feet 7, and after welding, the welded welding frame 4 and the welding feet 7 are moved outward from the joint part. Even if it protrudes, it is covered with an outer frame 8 so that the protruding portion is not directly visible from the outside.

欠点を有する。C. Problems with the prior art However, since the rim 5 and the outer frame 8 are not welded together, there is a gap g between them, which allows gasoline, wax, etc. to enter during manufacturing work, or during driving. Not only does muddy water seep in, causing the lens periphery to appear dark and impair its appearance, but also cracks occasionally occur in the welded parts, the welded frame 4 and welded feet 7, due to the intrusion of these foreign substances. It has the following disadvantages.
ニ 本案の目的
本案は、敍上の欠点を可及的に解消せんとする
もので、異物の侵入を無くし、その外観美を良好
にせんとすることを目的とする。D. Purpose of the Proposal This Proposal aims to eliminate the defects in the title as much as possible, and aims to eliminate the intrusion of foreign matter and improve its appearance.

せしめる点に特徴を有する。E. Main Points of the Proposal This proposal is based on the principle that when the welding frame 4 of the lamp body 1 and the welding feet 7 of the lens 6 are melted and crimped, the molten joint portion protrudes laterally from the joint surface when the welding frame 4 of the lamp body 1 and the welding foot 7 of the lens 6 are crimped. The welding frame 4 is shortened only by the length that becomes short.
and the dimension of the welding leg 7 in the melting and crimping direction, with an allowance length a in advance.
In addition, the allowance length a is set to be larger than the gap b between the tip of the outer frame 8 and the base of the rim 5 in the welding pressure direction, and after welding, the tip of the outer frame 8 is brought into close contact with the base. It has characteristics in points.

されている。F. Embodiment of the present invention Figure 1 shows a sectional view of the main parts of the embodiment of the present invention. The same parts as those of the conventional model described in Figure 2 are given the same reference numerals, and only the features of the present invention will be described. ,
a is a margin length that is taken in advance to take the length that will be compressed when the welding frame 4 and the welding foot 7 are melt-pressed by a hot plate; When melting and crimping the parts, the length b is determined in advance by taking into account the shortening of the part due to crimping, and b is the gap between the tip of the outer frame 8 of the lens 6 and the base of the rim 5 of the lamp body 1. This is the gap between the welding leg 4 and the welding leg 7 before they are heat welded, and after heat welding, it is closely connected to the base of the rim 5 to prevent outside air, dust, etc. from entering. Only No. 8 has a pointed tip. Since the allowance length a is set larger than the gap b, the tip of the bottom frame 8 is set in close contact with the base of the rim 5 after welding, as described above.

案所期の目的を充分達成し得る効果を奏する。G. Effects of the present invention The present invention has the above-mentioned configuration.Next, to describe the functions and effects, the dimensions of the welding feet 7 of the lens 6 have an allowance length a in advance in the direction of the melting and crimping between the tip of the outer frame 8 and the base of the rim 5. Since it is larger than the gap b,
When the joint surfaces of the welding frame 4 and the welding feet 7 are welded and compressed by welding, since either the outer frame 8 or the rim 5 is formed into a pointed shape, the outer frame 8 and the rim 5 are in close contact with each other. Perfect contact is maintained by force, and in this state there is no intrusion of solvents, muddy water, etc. Therefore, the appearance can be maintained, and cracks that occur in the joint due to the intrusion of foreign objects can be avoided. This has the effect of fully achieving the purpose of this proposal, such as eliminating
