摘要： Provided is a rotary knob rotational structure being less susceptible to the influence of variation in the dimensions of a rotary knob and reducing backlash of the rotary knob while providing a suitable magnitude of rotational resistance to the rotary knob.The rotary knob rotational structure includes an annular sheet 22 interposed between a device body and the rotary knob 14, an attachment member 24 configured to attach a fixed portion 22a of the annular sheet 22 to the device body with the fixed portion 22a being interposed between the attachment member 24 and the device body, and a body-side protrusion 26 contacting the annular sheet 22 on the outside of the fixed portion 22a in the radial direction of the annular sheet 22 to warp the annular sheet 22 toward the rotary knob 14.
