PROBLEM TO BE SOLVED: To obtain a door mirror device for a vehicle small and capable of suppressing variations in the property of an antenna. SOLUTION: The door mirror device 10 is equipped with the antenna 12, and a component fitting frame 14. Rust proof treatment is applied to the surface of the frame 14, and the frame is insulated electrically. When the antenna 12 is attached to the frame 14, a tapping screw 24 is inserted into both a plate 20 being electrically conducted to the matching board of the antenna 12, and the case 18 of the antenna 12 in the order of the plate 20 and the case 18, and the antenna is screwed on the frame 14. In this case, a surface treatment film by the rust proof treatment is torn away by the tapping screw 24, in the screwed part of the frame 14 with the tapping screw 24. Accordingly, the antenna 12 is fixed to the frame 14, becomes electrically continuous with the frame 14, and the frame 14 makes a ground for the antenna 12. COPYRIGHT: (C)2007,JPO&INPIT
