However, in this structure, the planetary shaft 1
Due to the slight play between the bearing member 5 and the
As shown in the figure, the planetary shaft 1 oscillated, and there was a possibility that considerable backlash would occur between the planetary gears 2 and 3 and the sun gears 6 and 7 on the column and pad sides that mesh with them. Therefore, abnormal noise may occur or the pad 8 fixed to the pad side sun gear 7 may
There was a problem in that the steering wheel vibrated, causing discomfort to the driver, and reducing the commercial value of the padded non-rotating steering wheel. In addition, when the planetary shaft 1 swings, the friction between the planetary shaft 1 and the end of the bearing member 5 becomes strained, which increases the risk of wear and resistance during steering operation. .
