Embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 and 2 show a first embodiment of the present invention. As shown in FIG.
It is made of an elastic material such as hard rubber, and the convex portion 2 on the front surface has a convex curved surface 3 having a substantially spherical shape. On the rear surface side, the engaging portion engages with the front side of the wheel portion 102 of the steering wheel 101. It has a mounting portion 4, and the central height H of the convex portion 2 is formed to be half or less of the width W of the assisting device main body 1. Note that the diameter of the convex portion 2 is substantially equal to the width W. The width W of the convex portion 2 is substantially equal to the width of the wheel portion 102. Further, an adhesive layer 5 is provided on the engagement mounting portion 4, and a sheet member 6 is provided on the adhesive layer 5 so as to be peelable. Also, the convex curved surface 3
Has a luminous property by a luminous material. In the drawing, reference numeral 103 denotes a spoke portion, 104 denotes a rotation center of the steering wheel 101, and a steering post is connected to a rotation center 104 on the back surface of the steering wheel 101. Further, in the above description, the example in which the assisting device main body 1 separate from the wheel portion 102 is mounted has been described, but the assisting device main body 1 may be formed when the steering wheel 101 is manufactured.

Next, the method of using the steering wheel 101 and the assisting device body 1 will be described. First, the sheet member 6 is peeled off from the engagement mounting portion 4 and the assisting device The main body 1 is bonded and fixed. Then, for example, as shown in FIG.
Auxiliary tool bodies 1 and 1 are respectively fixed at symmetrical positions on the left and right sides slightly below the center in the height direction of 2. In this way, the auxiliary tool bodies 1 and 1 are fixed to the left and right sides and slightly below, and by touching them, the direction of the steering wheel 101 can be determined. Then, if necessary, as shown in FIG. 1, the palm 111 is naturally opened, the palm 111 is applied to the convex portion 2 so as to envelop, and the convex portion 2 is slid in the palm 111 as it is rotated. Center 1
The operation of turning the steering wheel 101 around 04 can be performed.

As described above, according to this embodiment, the operation portion 2 is provided on the wheel portion 102 of the steering wheel 101 so as to protrude toward the surface of the steering wheel 101. Numeral 2 has a convex curved surface 3, and a palm 111 is attached to the convex portion 2, and the steering wheel 101 can be rotated to slide the convex portion 2 in the palm 111. In addition, since it has the convex spherical surface 3, it fits perfectly with the palm 111 that is naturally open.

As described above, according to the present embodiment, in the operation assisting tool attached to the front surface of the wheel portion 102 of the steering wheel 101, the back surface of the assisting tool main body 1 having the convex portion 2 on the front surface side Is provided with an engagement attachment portion 4 attached to the wheel portion 101, so that the palm 111 is attached to the projection 2 and the palm 1
The steering wheel 101 can be rotated so as to slide the convex portion 2 in the inside of the auxiliary tool body 11.
Since the engagement mounting portion 4 that engages with the front surface of the wheel portion 102 is formed on the back surface of the wheel tool 102, the auxiliary tool main body 1 can be easily mounted on the wheel portion 102.

[0015] As described above, in the present embodiment, claim 3
In response to the above, the assisting device body 1 is １ of its width W dimension.
Since the height T from the surface of the wheel portion 102 is smaller, the convex portion 2 has a convex curved surface 3, and the convex curved surface 3 is formed of an elastic material. However, it fits snugly into the palm 111 which is naturally open, and is easy to handle in combination with its elasticity.

Also, as an effect of the embodiment, since the adhesive layer 5 is provided in advance on the engagement mounting portion 4, the sealing member 6 covering the adhesive layer can be peeled off to easily attach to the wheel portion 102. Further, since at least a part of the surface of the assisting device main body 1 has a luminous property due to the luminous material, the assisting device main body 1 emits light at night or the like, and the steering wheel 101
And the decorativeness can be improved.
