Abstract

PURPOSE:To evade a breakdown of a rotating shaft by providing an engaged part to be engaged rotatably with the engaging part of the rotatinal center part of a knob, and thus preventing the knob in operation from falling into a cabinet owing to the shake, inclination, and depression of the knob. CONSTITUTION:When an intermediate engaging part 23 is pressed down while projecting pieces 25 and 26 are fitted in engaging grooves 19 and 20 of a lower cabinet 17, a rotating shaft part 16 is fitted in a bearing hole 27, and a hook pawl 21 is hooked in a hook recessed part 29, thereby fitting the intermediate engaging part 23 to the lower cabinet 17 so that the upper edge of the part 23 is in the same plane with the upper edge of the lower cabinet 17. At this time, a projecting part 28 abuts on a specifying seat 15, so a knob 13 has no upward and downward shake, and the knob 13 abuts on the intermediate engaging part 23 only by the specifying seat 15 and a part of the projection part 28, so rotating operation is performed smoothly. Then, an upper cabinet 24 is fixed to the lower cabinet 17.

It is an intermediate fitting part interposed between and integrally has projecting pieces 25 and 26 at both ends of a rectangular plate part that slide and fit into the low fitting grooves 19 and 20, respectively, and - A protruding part 28 having a bearing hole 27 into which the rotating shaft part 16 of the knob 13 fits is integrally provided on the surface, and the engaging claw 21 engages with the surface provided with the protruding part 28. Therefore, as shown in FIG. 3 and FIG.
When the intermediate fitting part 23 is pushed downward while fitting into the fitting grooves 19 and 20 of the lower cabinet 17, the rotating shaft part 16 of the knob 13 fits into the bearing hole 27, and the engaging claw 21 engages. The intermediate fitting part 23 fits into the recess '29 and becomes engaged, and the upper edge of the intermediate fitting part 23 is connected to the lower cabinet 17.
Lower cabinet 17KI@ so that it lines up with the upper edge of the
Add it to J. At this time, since a part of the protrusion 28 is brought into contact with the restricted dust 16 of the knob 13, the knob 13 does not wobble in the vertical direction, and the knob 1
3 and the intermediate fitting part 23 are only a part of the above-mentioned control dust 16 and the protruding part 28 (cabinet screw) 17[
The soil cabinet 24 is fixed against the soil cabinet 24.

。Furthermore, although the rotating shaft of the variable resistor 11 is short, thin, and easily damaged, this configuration prevents a direct load from being applied to the rotating shaft, thereby eliminating damage to the rotating shaft. It is something that can make you fall in love with someone and extend your lifespan. By engaging the intermediate fitting part 23 with the engaging claw 21 of the lower cabinet 17, it is possible to reliably prevent the knob 13 from shaking in the vertical direction, and as a result, the portion where the knob 13 is located can be prevented. Attachment of the printed circuit board 12 to the lower cabinet 17 does not require any screws, and it is possible to achieve WIJ installation.

るものである。In the above embodiment, the intermediate fitting part 23 is formed separately from the upper and lower cabinets due to the structure of the mold, but it may be formed integrally with the upper cabinet. Further, the engaging claw 21 and the engaging recess 29 are not necessarily necessary, and it is preferable to install them in order to more reliably suppress the stiffness of the knob 13.As explained above, according to the present invention, It is installed at the center of rotation of the knob on the intermediate fitting part attached to the lower cabinet.
By providing a test joint part that rotatably fits with the girder fitting part, it is possible to prevent the knob from wobbling, tilting and pressing when rotating the knob, screwing up the knob, and falling into the interior. This makes it easier to operate the knobs. Moreover, by adopting the above-mentioned structure, if a load is applied directly to the rotating shaft of the adjustment component, which has a weak mechanical strength, it will not become unstable and the rotating shaft will not be damaged.
