In the figure, there is a pair of bosses 2-1 in the cabinet 2.
is provided, and the dimension of the shaft 1-1 of the rotary knob 1 is set in accordance with the dimension A between the bosses 2-1. Further, the width is such that the opposing upper end of the cylindrical rib 2-2 provided coaxially with the boss 2-1 comes into contact with the diameter of the shaft 1-1, and the depth is the same as that of the shaft 1-1. Make a notch by the diameter of 1. Shaft 1 of rotary knob 1 is placed in this facing notch.
-1 is inserted. The presser piece 4 is fixed so as to abut against the shaft 1-1 using the boss 2-1 so that the shaft 1-1 does not come out from the opening of the notch. In this case, the pin 4-1 of the holding piece 4 is inserted into the boss 2-1. In addition, as shown in FIGS. 2 and 3, the washer 3-1 of the washer-equipped screw 3
The shaft 1-1 may be fixed by
As shown in FIG. 4, when assembling the equipment, the shaft 1-1 is held down by the holding piece 5-1 provided on the rear cabinet 5.
may be fixed. Since the shaft 1-1 is in contact with each side of the notch and the presser piece 4 in this manner, the rotary knob 1 can be rotated smoothly without rattling.

できる。Effects of the invention As described above, the rotary knob mounting device of the present invention forms the bearing part with a simple structure without using construction methods such as undercuts or butts on the mold. Supplying the rotary knobs to the parts is a process of ``placing objects,'' and can be done automatically. In addition, the fixing of the shaft can be automated since the presser piece is also supplied by "setting" or tightening with screws.
As a result, it is possible to significantly reduce costs by reducing mold costs and reducing man-hours through automation.
