    摘要: A method and apparatus for low-cost production of a lens for a vehicular lamp formed by integrally joining a plurality of synthetic resin lens members through vibration welding. The s apparatus includes a fixed portion and a vibrating portion, each have a lens fixing jig composed of a pair of respective holding jigs. The method includes the steps of supporting the respective lens members with one of the jigs, holding a lens member between a pair of holding jigs located close together, bringing each welding portion of the respective lens members into contact with each other by moving the vibrating portion and the fixed portion close together, and integrally welding the lens members by vibrating the vibrating portion.

    摘要: A vibration welding apparatus and a vibration welding method in which the weight of a vibrating member is reduced and large synthetic resin members can be vibration welded. A vibration welding apparatus for joining two synthetic resin members, such as vehicular lamp lens members, through vibration welding is provided with a vibration generating mechanism, a vibrating member vibrated in a predetermined direction by the vibration generating mechanism, a base, a fixed-side jig disposed on the base for holding a first synthetic resin member, a holding jig composed of a holding jig part fixed to the vibrating member, and a holding part slidably mounted on the base so as to be slidable in the direction of vibration of the vibrating member such that the second synthetic resin member vibrates synchronously with the vibrating member.

    摘要: In a lamp including a lamp housing and a lamp cover, the lamp cover is laser-beam welded to an opening edge portion of the lamp housing. There exists no trace of fusion on the opening edge portion of the lamp housing in any other areas than a surfaces abutment portion where the lamp cover is brought into abutment. A method for fabricating a lamp includes bringing a lamp cover into abutment with an opening edge portion of a lamp housing; and emitting a laser beam to a surfaces abutment portion of the lamp housing with the lamp cover so as to laser-beam weld the lamp housing and the lamp cover together. The emission of the laser beam is implemented while blocking the laser beam so that the laser beam is not emitted to at least any other areas of the opening edge portion than the surfaces abutment portion. An apparatus for fabricating a lamp includes support means for rotatably supporting a lamp housing and a lamp cover that is brought into abutment with an opening edge portion of the lamp housing in an abutment state; laser beam emitting means for emitting a laser beam to a surfaces abutment portion of the opening edge portion where the lamp housing is in abutment with the lamp cover; and laser beam blocking means for blocking the emission of a laser beam to at least any other areas of the opening edge portion than the surfaces abutment portion.

    摘要: A vehicular lighting fixture having an improved appearance, wherein a lamp body and a lens are welded to each other and the inner face of the lamp body is subjected to a surface treatment. The vehicular lighting fixture (1) includes a lamp body (2) having a recess (3) with a front opening, a lens (8) attached to the lamp body (2) in such a manner as to cover the front opening, and a bulb (12) disposed in a lighting fixture space (10) defined by the lamp body (2) and the lens (8). The inner face (13) of the lamp body (2) is subjected to a surface treatment and the lamp body (2) and the lens (8) are connected with each other through their respective welding legs (6 and 9). A groove (7) is formed as a stepped portion inwardly of the welding leg (6) formed on the lamp body (2) to position a masking jig which masks the welding leg of the lamp body from the surface treatment. Also, the width of the legs (6 and 9) are different from each other.
