Abstract:
1. A vehicle lighting device, comprising: (i) a lamp housing, which partitions a lamp room, and a lamp lens; (ii) a light illuminating portion which is disposed in the lamp room and externally illuminates through the lamp lens; (iii) a wire heater provided by means of transfer at a portion of the lamp lens, through which light from the light illuminating portion of the lamp lens is permeated; (iv) a power-feeding portion which is integrally provided at the wire heater, for feeding a power current to the wire heater; and (v) a connector which is provided at the power-feeding portion and is electrically connected to a power source-side connector, wherein the wire heater is a transfer-type heater including: (a) a base film; (b) an adhesive provided on one face of the base film; (c) an electrically conductive member for heater, which is formed in a wire pattern on the other face of the base film, a power current being fed, thereby generating a heat; and (d) a resist provided on the other face of the base film so as to cover the electrically conductive member for heater, at least the base film being cut in a pattern that follows the wire pattern of the electrically conductive member heater and which is caused to adhere the adhesive to the lamp lens, thereby transferring the electrically conductive member for heater to the lamp lens, the power-feeding portion including: (e) a power-feeding film integrally provided on the base film; and (f) a power-feeding electrically conductive member which is formed in a wire pattern on one face of the power-feeding film, one end of which is electrically connected to the electrically conductive member for heater; the connector including: (g) a terminal which is set at the power-feeding electrically conductive member on said one face of the power-feeding film; (h) a first swaging portion for swaging and fixing the terminal and the power-feeding portion to each other in a multilayered state; and (i) a second swaging portion for swaging and fixing the terminal, the power-feeding portion, and the first swaging portion to each other, in a state in which the first swaging portion has swaged and fixed the terminal and the power-feeding portion to each other, wherein: a hole is formed at a respective one of the terminal and the power-feeding portion; the first swaging portion has a hollowed protrusion to be inserted into the hole of the respective one of the terminal and the power-feeding portion in the multilayered state, the protrusion being inserted into the hole of the respective one of the terminal and the power-feeding portion, thereby swaging and fixing the terminal and the power-feeding portion to each other in the multilayered state; and the second swaging portion has a swaging protrusion to be inserted into the hollow of the protrusion of the first swaging portion, the swaging protrusion being inserted into the protrusion of the first swaging portion, in a state in which the terminal and the power-feeding portion are swaged and fixed to each other, thereby swaging and fixing the terminal, the power-feeding portion, and the first swaging portion to each other.
