A conventional vehicle lighting device has entailed a problem on swaging and fixing a power-feeding portion and a connector to each other insofar. In the present invention, a connector is made up of: a male terminal set at a power-feeding electrically conductive paste on one face of a power-feeding film of a power-feeding portion; a grommeted terminal board (primary swaging tool) on which the terminal and the power-feeding portion have been swaged; and a resin board (secondary swaging tool) on which the male terminal, the power-feeding portion, and the grommeted terminal board have been swaged. As a result, in the present invention, a swaging fixing strength between the power-feeding portion and the connector can be improved by means of the primary swaging fixing of the grommeted terminal board and the secondary swaging fixing of the resin board.

Vehicle lighting device

A vehicle lighting device includes: a heat sink member; a semiconductor-type light source directly placed on a top face of the heat sink member; a power-feeding holder which is set on the semiconductor-type light source and the heat sink member, for holding the semiconductor-type light source at the side of the heat sink member and feeding a power current to the semiconductor-type light source; and a fixing member which is covered on the power-feeding holder and fixed to the heat sink member, for fixing the power-feeding holder to the heat sink member and sandwiching and fixing the semiconductor-type light source between the power-feeding holder and the heat sink member. As a result, this vehicle light device improves workability of assembling components.

A conventional vehicle lighting device entails a problem on appearance. A vehicle lighting device of the present invention is provided with a wire heater, an extension portion, and a power-feeding portion. An adhesive part is provided at a part of one face of an extension film of the extension portion. Of such one face of the extension film of the extension portion, a letterpress printed-film pattern of a rough portion is provided in a range excluding the adhesive part. As a result, the vehicle lighting device of the present invention provides an ability to reliably prevent an extension film of the extension portion from sticking to a lamp lens by means of the letterpress printed-film pattern of the rough portion; prevent an appearance failure or abnormality exerted by the sticking of the extension film of the extension portion to the lamp lens; and improve its appearance.
