いう問題を引起していた。Problems to be Solved by the Invention However, in this case, the variable resistor 1 is an ultra-small component, and its rotating shaft is short and thin, so the rotation operation is performed while pressing the external protrusion of the knob 4 with your finger. When doing so, phenomena such as wobbling and tilting of the knob 4 occur, which reduces the amount of protrusion of the knob 4 from the cabinet, making it difficult to operate and degrading the quality of the product. This phenomenon is particularly noticeable in the case of ultra-small products, and the load applied to the rotating shaft during the knob rotation operation shortens the life of the product and causes problems such as damage.

くなるものである。Effects of the Invention As explained above, according to the present invention, the intermediate fitting part attached to the lower cabinet is provided with a fitted part that rotatably fits with the fitting part provided at the center of rotation of the knob. This eliminates the phenomenon of the knob falling into the cabinet due to wobbling, tilting, and pressing of the knob during rotation of the knob, thereby making it easier to operate the knob. In addition, by adopting the above configuration, it is possible to directly connect to the rotating shaft of the adjustment component, which has weak mechanical strength.
Since no load is applied, there is no possibility of damage to the rotating shaft.

て滑らかで、傾きが起こらない利点を有する。 That is, by providing a cylindrical fitting shaft part integrated with the knob, the diameter of the rotating shaft of the adjustment component can be equivalently increased, and the rotating shaft and the fitting shaft part fit into this fitting shaft part. Since it has a separate bearing part that regulates the position of the shaft and the bearing on the same axis and maintains its posture, the relationship between the shaft and the bearing can be easily lengthened and enlarged as necessary, resulting in a strong bearing structure. is formed, and the external force of the knob operation is not applied directly to the investigation part, so that it can be protected from damage. In addition, since the bearing fit of the mechanical element can be set under optimal conditions, the rotation of the knob operation is extremely smooth and has the advantage that no tilting occurs.

とができる。 In addition, with this type of knob position regulation, the knob tends to tilt, but since the bearing portion is long, the knob does not tilt easily, which can improve quality, especially in the case of small products. That is, since the length in the axial direction, that is, the bearing size, can be arbitrarily set to the optimum conditions, the inclination of the knob can be kept to a minimum, and its rotation can be made very smooth.

皆無であるという利点も有するものである。 Furthermore, since the bearing part is a separate piece,
It is possible to select a bearing device with the optimal shape for free placement regardless of the cabinet, and these are essential for small products. In addition, the bearing part is
Because it is provided on an intermediate fitting part that is different from the cabinet body, there is no problem of sink marks, welds, etc. occurring on the cabinet surface when forming the bearing part onto the cabinet body. It also has advantages.

素化をはかることも可能となる。 In addition, by engaging the intermediate fitting part with the engaging claw of the lower cabinet, it is possible to more reliably prevent the knob from rattling in the vertical direction, and it is also possible to prevent the knob from shaking in the vertical direction. There is no need for screws, and it is possible to simplify the installation.
