A vehicular lamp having an inner lens is described. In an implementation, an annular wall A surrounding an optic axis Ax of a reflector is formed on the inner lens disposed between am outer lens and a reflecting surface of the reflector . The inner lens is divided by the annular wall A into an internal zone B and an external zone C which may be different from each other in convex-concave lens shape. The internal zone B may be formed of a translucent lens, and a plurality of grid-type lens elements C may be formed over the entire rear surface of the external zone C. Thus, an observer viewing the interior of a lighting chamber from a location in front of the lamp will see that the internal zone B and the external zone C, which are divided by the annular wall A, are significantly different. The configuration of elements provides a vehicular lamp that is visually attractive.

Vehicular lamp

A vehicle lamp includes a lens attached to a lamp body, the lens including a curved portion, a circumferential wall-like attachment rib projecting from an inner surface of the curved portion of the lens and having an even projection height, and a sealing plate having a circumferential edge portion and a cover portion on an inner side of the circumferential edge portion for ultrasonically welding a welding portion formed in the circumferential edge portion to the attachment rib, and a reflection portion including a plurality of recursive reflection elements formed in a space defined by the lens, the attachment rib and the sealing plate, wherein a pressed portion extends from the circumferential edge portion in a direction opposite to the lens, the pressed portion being adapted to be pressed against a vibrating portion of an ultrasonic welding apparatus and formed in the sealing plate so that a forward end surface of the pressed portion is located in the same plane.
