To prevent a deformation preventing mechanism for a rotation operating shaft, in which the rotation operating shaft can be prevented from deforming when an operating knob is subjected to an impact force even when a hard operating knob is fitted into the rotation operating shaft of the rotation operating part.
In a mounting structure of the rotation operating part, the rotation operating part 2 is secured to a chassis 1 with a nut 3 screwed to a male screw set in the periphery of a bearing 2b rotatably supporting the rotation operating shaft 2a of the rotation operating part 2 by feeding thereof through a hole. A rotation operating shaft surrounding part 3a which feeds the rotation operating shaft 2a for the nut 3 near or in contact state thereof is integrally formed.
