4 is provided.

FIG. 2 is a perspective view showing the hook member, and FIG. 3 is a front view thereof. The hook member 13 is connected to the left and right positions of the front end 47 of the mounting portion 14, and is bent at a right angle to form the first hook 15 and the second hook 16 on the left and right of the front side. The third hook 17 on the back side, which is formed by bending into
One screw hole 49 is opened, and a flange 18 is provided at the base of the first hook 15 and the second hook 16 so as to be flush with the hook.

The hook member 13 is the first hook 1
5 and the leg portions 15a, 16a of the second hook 16 have plate-like claw portions 20, 21 projecting in mutually opposite directions and extending along a plane in a direction intersecting the mounting portion 14 at substantially right angles, At the tip of the leg 17a of the hook 17 of the
It has an engaging piece 22 in the shape of a rectangular plate substantially parallel to.

The first hook 15 and the second hook 16 have plate-like leg portions 15a, 16a in which the tips are slightly inclined in a direction away from each other, and the length from the plate surface to the tip of the attachment portion 14 is large. The protrusion lengths of the claw portions 20 and 21 are different from each other. The length from the plate surface to the tip of the mounting portion 14 is set such that the first hook 15 is longer than the second hook 16 and the third hook 17 is set to an intermediate length between them, so that both claw portions are 20 and 21 are located at different distances from the plate surface of the mounting portion 14. The lateral protruding length of the claw is the second
The hook portion 21 of the hook 16 is longer.

Each of the claw portions 20 and 21 has a corresponding leg portion 15.
Straight edges 20a and 21a for retaining which are substantially perpendicular to the outer edges of a and 16a, and a curved edge 2 formed along a curved line
0b and 21b, straight edges 20a and 21a, and curved edge 20
20c, 21c at the point where b and 21b intersect
It has and. The engagement piece 22 is provided with bilaterally symmetric overhanging plate portions 22a, 22a on both sides, and its width is made slightly larger than the width of the inter-limb notch 26 of the shock absorbing member 5.

The hook member 13 is for supporting the hook pad 9 on the shock absorbing member 5 and mounting it by engaging each of these hooks with a corresponding predetermined position of the shock absorbing member 5.

FIGS. 4 and 5 are front views showing the relationship between the movement of the hook member and the shock absorbing member when the horn pad according to the above embodiment is mounted. First, the leg portion 15 a of the first hook 15 is put into the square hole 23 in the base plate portion 6 of the shock absorbing member 5, and the claw portion 20 is hooked in the square hole 23. Next, the claw portion 21 of the second hook 16 is dropped into the hole edge notch 24, and the engaging piece 22 is inserted into the inter-limb notch 26, and then the position of the horn pad 9 is slightly moved to the front side. The claw portion 21 of the second hook 16 is displaced from the position of the hole edge cutout 24. Further horn pad 9
By pushing in, the resin hook 10 is inserted into the circular hole 25 and hooked.

According to the above embodiment, the hook member 13 is
By hooking and engaging the respective claw portions 20 and 21 of the first cook 15 and the second hook 16 with the square holes 23 in the base plate portion 6 of the shock absorbing member 5, the horn pad 9
Support. In the first hook 15 and the second hook 16 according to the present invention, the lengths of the leg portions 15a and 16a are different from each other, and the one claw portion 21 is provided in the hole edge cutout 24 of the impact absorbing member 5.
By passing it through, you can attach and detach it without discomfort.

Further, the hook member 13 when it receives an impact
With respect to the deformation of itself, the tips of the legs 15a and 16a are slightly inclined in the direction away from each other, and
By providing the flange 18 at the base of a, 16a,
In particular, it is possible to suppress a decrease in the mutual distance between the first hook 15 and the second hook 16. On the other hand, the third hook 17 connects the engagement piece 22 to the shock absorbing member 5
The horn pad 9 is positioned in the inter-limb notch 26 to support the force for shifting the horn pad 9 in the left-right direction or the force for rotating the horn pad 9.

The horn pad 9 is used depending on the inclination angle of the steering shaft on which the steering wheel 1 is mounted.
Since there is a difference in the difficulty of falling off, it is easy to select whether or not to install the hook member 13 depending on the difficulty of falling off. Usually, the hook member 13 and the bolt 39 for mounting the hook member 13 are hidden behind the horn pad 9 or under the emblem, so that the appearance is not spoiled.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the invention. For example, the notch of the shock absorbing member or the engaging piece of the hook member may have a shape other than a quadrangle.

[0023]

According to the present invention as set forth in claim 1, the hook member has a claw portion projecting in mutually opposite directions and extending along a direction intersecting with a mounting portion mounted on the horn pad.
And a second hook, and a third hook having an engaging piece that is substantially parallel to the mounting portion. Each of these hooks is engaged with a corresponding predetermined position of the shock absorbing member so as to prevent the horn from falling off. By mounting the pad while being supported by each hook, the engaging pieces and the two claws in different directions are retained and supported by the shock absorbing member, and the first hook and the second hook are vertically and horizontally arranged. Since the horn pad is supported against vibration or deformation, and the third hook supports the horn pad against vibration or deformation in the left-right direction and the rotation direction, no matter what position and direction an impact force is applied to the steering wheel, The pad can be attached without falling off. Further, in the present invention as set forth in claim 2, both claw portions of the claw portion of the first hook and the claw portion of the second hook are located at different distances from the mounting portion, and Since the protruding lengths are different, the horn pad can be smoothly attached and detached. In the present invention according to claim 3, the first hook and the second hook have
By providing the flange, both hooks themselves become solid and difficult to be deformed. In the present invention according to claim 4, the hook and the engaging piece are inserted into the shock absorbing member. By providing the notch, the horn pad can be attached and removed smoothly and easily.
