Engaging projections 2b 3 wraparound portion slope c of (arrow A is a direction of assembly of the lens, and this parallel arrows c and oblique top surface of the wall portion of the sealing groove 1a) obliquely in contact with the There is a problem of slipping. That is, by applying a force of an arrow P direction in the lens 2 as shown in FIG. 4, the engaging projection 2b 3
When the attempts to insert into the engaging hole 1b 3 as the arrow c, sliding in the direction of the arrow b against the inclined surface 1c. For this reason,
The engaging projection 2b 3 hardly inserted into the engagement hole 1b 3. The present invention has been made in view of the above circumstances, and even in a vehicular lamp having a wraparound portion, an engagement projection provided on a lens leg is engaged with an engagement projection provided on a wall of a seal groove. An object of the present invention is to provide a lens mounting structure that can be quickly and easily engaged with a hole.

ほぼ直角な縁を有していることを特徴とする。The basic principle of the present invention created to achieve the above object will be described by comparing FIG. 1A corresponding to the embodiment with FIG. 4 related to the conventional example. Briefly, in the conventional example (FIG. 4), the reason that the engagement projection 2b 3 slides in the direction of arrow d is that the slope 1c is inclined with respect to the arrow c (almost parallel to the arrow P, that is, the direction in which the lens 2 is assembled). Because they had exchanged. Therefore, in the present invention, as shown in FIG. 1A, a notch 1d having an edge substantially perpendicular to the arrow c is provided. As a result, sliding in the direction of arrow d does not occur. According to the configuration of the present invention based on the above-described principle, a lens is disposed so as to cover a front opening of a lamp housing, a seal groove is formed around the front opening of the lamp housing, and a leg formed in the lens is provided. Is inserted into and bonded to the seal groove, and a projection integrally formed on the leg of the lens is engaged with an engaging hole provided in a wall of the seal groove. A notch is provided at an edge of the seal groove, and the notch has an edge substantially perpendicular to a direction in which the lens is assembled to the lamp housing.

The present embodiment is an improvement obtained by applying the present invention to the conventional example shown in FIG. 4, and the parts denoted by the same reference numerals as those in FIG. is there. Next, the difference between FIG. 1A and FIG. 4, that is, matters improved by applying the present invention will be described. More specifically, at the edge of the seal groove 1a,
the edges of the side walls 1a 1 of a, notch 1d is provided, and said notch 1d has an edge perpendicular to the arrow c.
In other words, the inclined surface 1c of the side walls 1a 1 of the sealing groove 1a is,
It is cut off at a plane perpendicular to the arrow c. When the order engaging projection 2b 3 is pressed in the direction of the arrow c to insert the engagement hole 1b 3, the engagement projection with the notch 1d (details notch 1

FIG. 1B shows an embodiment different from the above. This example precedent (FIG. 1 (A)) differs from the is that the formation of the leaving thin portions 1e cutout 1f on the side walls 1a 1 of the sealing groove 1a. Even if the notch 1f having an edge perpendicular to the mounting direction of the lens is provided as in this embodiment, the same effect (slip prevention) as in the above embodiment can be obtained.
