Claims (1)

[Claims for Utility Model Registration] A hopper at the top of a boss portion of a steering wheel having approximately T-shaped spoke portions, with left and right edges projecting between the spoke portions that extend to the spoke portion and are approximately orthogonal to each other. is disposed below the horn pad, and a movable contact plate attached to the horn pad side and a fixed contact plate attached to the boss portion side are disposed facing each other, and between the two plates, A biasing means for biasing the mutual plates to separate from each other, and a regulating portion for locking the upper surface of the movable contact plate to regulate the separation distance between the mutual plates, each of three
The left and right edges of the horn pad are respectively arranged as operating parts, and the two plates are brought into contact with each other by pushing down or pulling up the left and right operating parts in two directions. A horn switch for a steering wheel that operates a horn by turning the steering wheel, wherein the three regulating parts are a central regulating part, a left regulating part, and a right regulating part, and when viewed from above, the central regulating part is in the horizontal direction of the steering wheel. an inverted isosceles that is arranged on the center line of the triangle formed by the left and right regulating parts and the center regulating part, and has an angle of 90° or less with the center regulating part as the apex, and is symmetrical with respect to the center line; The right operating part of the horn pad is arranged at a position forming a triangle, and the right operating part of the horn pad is located on a right orthogonal line that is orthogonal from the left regulating part to a right reference straight line connecting the central regulating part and the right regulating part, when viewed from above. and is arranged at a position where the distance from the right reference straight line is equal to the distance from the left regulating part to the right reference straight line, and the left operating part of the horn pad is located at a position where the left operating part of the horn pad is connected to the central regulating part when viewed from above. a position on a left orthogonal line that is orthogonal from the right regulation part to the left reference straight line connecting the left regulation part, and where the distance from the left reference straight line is equal to the distance from the right regulation part to the reference straight line; A horn switch for a steering wheel, characterized in that the three biasing means are arranged near each of the three regulating portions with equal force.
