<P>PROBLEM TO BE SOLVED: To form a shape of the breathing port surroundings by an identical die without making die correction according to the case in which a waterproof grommet is used for the breathing port and the case in which respiratory cap is used. <P>SOLUTION: This is a vehicular lighting fixture 1 in which a breathing port 7 for making pressure control of a lamp chamber 4 formed by a housing 2 and a lens 3 covering the aperture of a housing 2 is formed in a housing 2. A small diameter circumferential wall part 50 of cylindrical shape and a large diameter circumferential wall part 51 which is concentric with and has a higher wall than the small diameter circumferential wall part 50 are formed at the periphery of the breathing port 7. The small diameter circumferential wall part 50 has a lower circumferential wall part 53 of cylindrical shape which is inserted into a housing hole formed in a grommet 10 and contacts the inner circumferential wall of the housing hole and an upper circumferential wall part 54 in which a cut-off part 55 is formed on a cylindrical shape. The large diameter circumferential wall part 51 has an inner wall of almost the same diameter as the outermost diameter of a breather cap 30 and has a cylindrical shape capable of inserting the breather cap 30, and has an aperture 57 for conducting air into the circumferential wall face of cylindrical shape. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
