Description of the Related Art Conventionally, a plurality of operating knobs for switching, setting, adjusting, etc. are provided in operating sections of various machines and devices. Here, a fitting structure of the operation knob and the shaft according to the conventional technique is shown in FIG.

状に対応する形状に形成されている。On one side surface of the operation knob 1 having a circular shape, a knob portion 2 for squeezing by the operator's finger and rotating the operation knob 1 in a predetermined direction is bulged and formed. A bottomed hole portion 3 is formed in the center portion on the side opposite to 2. One end 6 of a shaft 5 protruding from the operation panel 4 is fitted and inserted in the bottomed hole 3, and the one end 6 is formed by cutting out in a D-shaped cross section. Further, the bottomed hole portion 3 of the operation knob 1 is formed in a shape corresponding to the cross-sectional shape of the one end portion 6 of the shaft 5.

ヤ機構等を通じて所望の操作がなされる。In this case, when the operator grips the knob 2 and rotates the operating knob 1 in a predetermined direction, the rotational force of the operating knob 1 is transferred through the one end 6 having a D-shaped cross section. A desired operation is performed through a gear mechanism (not shown) that is transmitted to the shaft 5 and engages with the shaft 5.

Each shaft 5 fitted to the plurality of operation knobs 1
May be made of different materials such as metal and resin, and the diameter of the shaft 5 is set to a predetermined dimension in accordance with the strength of the material characteristics of the shaft 5. .

ている。That is, since the metal shaft 5 has a high strength, the diameter of the portion of the operation knob 1 fitted into the bottomed hole portion 3 can be set to be relatively small.
Since the shaft 5 made of resin has a low strength, the diameter of the fitting portion is set to be relatively large. For this reason, various operation knobs 1 having different diameters of the bottomed hole portions 3 corresponding to the material of the shaft 5 are prepared even if the outer shapes are substantially the same.

When one type of operation knob 1 is used, the diameter of the metal shaft 5 having high strength is unnecessarily increased, or a part of the resin shaft 5 is strengthened to reinforce its strength. However, there is a disadvantage in that it has to be constructed by another member having a high cost.

となり、製造コストが高騰するという不都合がある。Furthermore, it is necessary to select and manage a plurality of operation knobs 1 having different diameters of the bottomed holes 3 corresponding to the material of the shaft 5, and the plurality of operation knobs 1 are resin-molded. Therefore, a plurality of resin molding dies are required, and there is an inconvenience that the manufacturing cost rises.
