PROBLEM TO BE SOLVED: To provide a vehicle alarming horn that can attain electric conduction between a movable contact point supporting plate and a part of a magnet wire by rivet caulking alone without removing an insulating coating film and can maintain the electric conduction state without fail.SOLUTION: A movable contact point part 7a gets in contact with a fixed contact point part 8a when electric conduction to an electromagnetic coil part 2 is interrupted, and is separated from the fixed contact point part 8a when electric conduction to the electromagnetic coil part 2 is attained. A second rivet 21b is fixed to a housing 1 by caulking to secure a fixed contact point supporting plate 8 and a movable contact point supporting plate 7 and press a part of a magnet wire 20 with the movable contact point supporting plate 7 in between. The movable contact point supporting plate 7 has a projection part 7p1 projecting from a flat part 7f. The projection part 7p1 removes an insulating coating film 25 of the magnet wire 20 and is in contact with a conductor 26 of the magnet wire 20, with the movable contact point supporting plate 7 being fixed by the second rivet 21b.SELECTED DRAWING: Figure 4 |
