Claims

[Claims for Utility Model Registration] 1. A steering wheel equipped with a planetary gear mechanism for making the pad part immobile and an optical communication mechanism for performing optical communication by sandwiching the rotation locus of the boss plate or spokes. In, planetary gear mechanism (10, 13, 23, 24, 29
A pad part base 32 and a column side base 12 are provided at the pad side end and column side end of the pad part base 32, respectively, and a pad side light scattering chamber 34 is recessed in a part of the pad part base 32 toward the pad side. At the same time, a column side light scattering chamber 36 facing the pad side light scattering chamber 34 is recessed further toward the column side in a part of the column side base 12, and each light scattering chamber 34, 36 receives an optical signal. A steering wheel characterized by being provided with a light emitting element 56 that emits light and a light receiving element 63 that receives the optical signal. 2 Each of the light scattering chambers 34 and 36 is connected to the spokes 7a to 7a.
7d or longer than the width of the planetary gears 23, 24, 29. 3. The steering wheel according to claim 1, wherein the light scattering chambers 34 and 36 are provided below the pad base 32 and the column base 12, respectively. 4. The steering wheel according to claim 1, wherein the inner surface of each of the light scattering chambers 34 and 36 is coated to scatter light.
