Claims

[Claims for Utility Model Registration] 1. A planetary gear mechanism that makes the pad part non-rotatable, and further includes a hollow disk-shaped insulating substrate 10,1
A plurality of divided slip rings 11 and 18 are arranged insulatingly from each other on the circular sliding line R of 9;
In a steering wheel in which a relay mechanism 5 consisting of contact pins 17b, 17a whose tips are in sliding contact with the split slip rings 11, 18 is incorporated into the planetary gear mechanism, keys 35a, 35b, 35c or key groove 35 are provided.
, 35m, 35n,
The first engaging portion 35 is provided on the inner circumferential surface 34b of the rim portion 34 of each of the sun gears 23, 25 or the wall surface of the through hole 39 in a non-rotationally symmetric manner, and is provided on the outer circumferential surface 10a of the insulating substrates 10, 19. A steering wheel characterized by being provided with a second engaging portion 37 that engages with the steering wheel. 2. The first engaging part 35 and the second engaging part 37 are provided with a retaining means to prevent them from separating from each other in the engaged state.
Steering wheel as described in section.
