Claims

[Claims for Utility Model Registration] (1) A shaft with a flange whose rear end is attached to the output shaft of a rotary encoder, has a flange part in the middle, and whose tip extends through an operation panel to the front thereof, and the flange a sliding plate held so as to be in sliding contact with a flange portion of the attached shaft; an adjusting screw screwed into the mounting fixture of the rotary encoder;
and a compression spring held by the adjustment screw so as to press the sliding plate at its tip, and the pressing force of the compression spring is adjusted by operating the adjustment screw from the back side of the operation panel. Rotary operating force adjustment structure for rotary encoder. (2) A presser plate is provided between the sliding plate and the compression spring, the tip of the compression spring contacts the presser plate, and the sliding plate presses against the flange of the flanged shaft via the presser plate. The rotational operating force adjustment structure for a rotary encoder as set forth in claim 1 of the registered utility model, characterized in that the structure is pressed against a portion of the rotary encoder.
