There is a vehicular lamp that has a sense of unity with a vehicle body.

FIG. 2 shows an example of such a conventional tail lamp.

The front and rear directions of the tail lamp are directions in which light is emitted when the vehicle is mounted on the vehicle, that is, the rear of the vehicle is the front, and the front of the vehicle is the rear.

Reference numeral a denotes a tail lamp provided at the rear right corner of the body b of the automobile. The tail lamp a has a substantially bowl-shaped lamp body c and a front surface disposed to cover the front opening of the lamp body c. Lens d and lamp body c
And a valve e disposed at a predetermined position.

The lamp body c is formed so that its opening surface is displaced rearward as it goes to the right, the inner surface thereof is a reflecting surface f, and the opening edge of the lamp body c is opened forward. A lens installation groove g is formed.

The lens mounting groove g of such a lamp body c is usually opened in the same direction in relation to a mold.

The front lens d is curved so that the right portion thereof is displaced rearward as it goes rightward, and has a bent portion h bent leftward at its right end.
Is formed, and the front lens d thus formed is formed.
A lens mounting leg i, which projects rearward and is fitted into a lens mounting groove g of the lamp body c, is formed integrally with the peripheral edge of the bent portion h and the leading edge of the bent portion h.

The front lens d thus formed covers the front opening of the lamp body c so that its lens mounting leg i
Is attached to the lamp body c in a state fitted in the lens installation groove g of the lamp body c.

The tail lamp a thus assembled has a lens mounting groove j formed on the right side edge of the lamp body c in a lamp mounting hole j formed in the rear right corner of the vehicle body b. Thus, the front surface d of the front lens d attached to the lamp body c is positioned so as to be continuous with the rear surface and the right side surface of the vehicle body b.
