ABSTRACT:
A vehicular lamp including a lamp body having a front opening, a shelf member integrally formed on an outer surface of a peripheral part of the front opening and extending entirely along the peripheral part thereof, a seal groove defined between the shelf member and the peripheral part of the front opening, and a volume reducing groove formed in the vicinity of a junction of the peripheral part of the front opening and the shelf member, and an outer lens coupled to the lamp body. The outer lens has a seal leg inserted in the seal groove of the lamp body and secured thereto by a sealing material. The thickness of the junction, i.e., the volume of resin at the junction, is reduced by the volume reducing groove to thereby avoid generating undesirable shrinkage during the resin molding process. Accordingly, the external appearance of the lamp body is not degraded, even in the inside portion of the lamp body which can be viewed from the outside, because there is no concave portion on an inner surface of the lamp body.
