DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a wooden steering wheel device for a vehicle such as an automobile.

[Technical background of the invention]

Traditionally, the main components of steering wheels for automobiles, etc.
For example, if a vehicle is designed to generate a stronger warning sound or a weaker warning sound depending on the driving situation, for example, ? There are some as shown in Figures 1 and 2. That is, a horn button (5) having a contact point 14) with respect to the horn plate (3) K of the grounding part is provided on the fiber side of the spoke part r21 of the steering wheel (1), and one spoke part (2
) is provided with a main button 18) having a contact point (7) for the spoke core metal 16) of one earth.

If you want to generate a normal strong warning sound, press either of the horn buttons 15) on both sides to bring the contact (4) into contact with the horn plate (3), and the horn (9) that produces a strong warning sound is pressed. If you wish to emit a weak warning sound on a busy street, press the central horn button (8) and connect the contact point (7) to the spoke core +
By making contact with 61 K, the horn UOV will sound, emitting a weak warning sound.

[Problems with background technology]

In the case of such a horn device, there are many constituent parts, and assembly is troublesome, and the stroke of the horn button and the operating pressing force vary depending on the shape of the lever assembly 9 of each part.

In addition, in order to activate the horn, the horn button must be pressed and the horn plate must be primed.
It takes time for the system to operate, causing delays in emergency operations.

Furthermore, due to the mechanical structure, there is a possibility that parts may deteriorate during long-term use, or that water, dirt, etc. may adhere to the contact points and cause them to fall under the horn.

Moreover, it is necessary to assemble a plurality of water units for different strengths and weaknesses, which is time-consuming.

[Purpose of the invention]

The present invention seeks to solve these problems, and aims to provide stable operation during long-term use by using a non-contact electric type horn operating section.

[Summary of the invention]

The present invention provides a wooden actuator pupil on the top surface of a steering wheel consisting of a boss part, spoke parts and a rim part, which operates a wooden blowing mechanism by blocking an optical path from a light emitting element to a light receiving element. A light emitting element and a light receiving element are arranged facing each other at a distance of 2 or more pairs, and each set of light emitting elements and light receiving elements is blocked, thereby generating different warning sounds. It is characterized by:
