Claims

[Claims for Utility Model Registration] A rotating shaft that rotates over a predetermined angular range, and a serration on the inner periphery that fits into the serrations that extend in the axial direction of the rotating shaft and that are located on the outer periphery of the rotating shaft. A knob member comprising a fitting hole, a knob part projecting from the outer periphery of the fitting hole, and an index provided on the knob part, and when the knob member is rotated together with the rotating shaft within the predetermined angle range. and a scale that indicates the amount of rotation of the rotary shaft according to the position of the index is mounted in the apparatus, wherein the serration is absent on at least one of the tip portions of the rotary shaft and the fitting hole of the knob member. and has a serration-deficient portion in which the rotation is not transmitted to the rotation shaft when the knob member is rotated, and a tip of a fitting hole between the rotary shaft and the knob member is connected to the serration-deficient portion. abutment pieces that are fitted together and stop the rotation of the knob member when the knob member is rotated on the rotating shaft by abutting against each other at a position where the index corresponds to one end of the scale; and a support member that supported the rotating shaft, and when the rotating shaft is rotated to one end at a predetermined angle, the tip of the rotating shaft and the fitting hole of the knob member are fitted into each other. When the mating pieces are mated together, the knob member is inserted deep into the rotating shaft, and the serrations of the rotating shaft and the fitting hole of the knob member are fitted into each other. A special feature is the installation of the rotating knob.
