According to the tilting structure of the conventional steering wheel configured as described above, when the rotary knob 32 is rotated, the pinion 31 is rotated, and the rack 11 is linearly reciprocated by this rotational force, and thus, the steering column ( 1) is to be moved up and down integrally with the sliding bracket 12 to the circular motion is to change the angle of the steering wheel (4).

However, in the conventional steering apparatus configured as described above, getting on and off by rotating a steering column 1 having a steering shaft (not shown) to secure a space so that interference with the steering handle 4 does not occur when the driver gets on and off. It can help, but there are many types of parts required for this, and also, because each part is expensive, there was a problem that the cost increases.

In addition, since a large number of parts are used for tilting the steering column 1, a malfunction may occur in the binding force and the connection relationship of each part. As a result, the tilting operation may not be performed accurately, resulting in a decrease in productivity and reliability of the product. There was this.

The present invention was devised to solve the above-mentioned problems, and to provide a steering wheel for automobiles that can reduce costs by preventing interference between the driver and the steering wheel when the driver gets on and off using simple and inexpensive parts. The purpose is.

Another object of the present invention is to improve productivity by using a small number of parts for folding the steering wheel and to prevent malfunctions and to improve the reliability of the product.
