摘要：
The objective of this invention is to provide a compact rotary encoder with no axial play, and in order to achieve this objective, the cylindrical operating shaft is supported by the cylindrical support shaft extending up from the bottom surface of the rotary encoder base member so that the attachment portion of the control knob and the fitting portion of the cylindrical operating shaft can be made longer, whereby inclination in the control knob and play in the fitting portion of the operating shaft can be reduced while keeping the overall height of the rotary encoder small.
