く、係合部１６よりも小さな外形に設計する。Embodiment Hereinafter, a dial device according to an embodiment of the present invention will be described with reference to the drawings. 1, 2 and 3 show an embodiment of the present invention. In FIGS. 1 to 3, the gear portion 7 of the tuning knob 3, the gear portion 6 of the intermediate gear 11, and the gear portion 1 of the variable converter drum 5 are engaged with each other, and by rotating the tuning knob 3, the variable converter drum 5 is rotated. It has a structure. The intermediate gear 11 is fixed by being temporarily engaged with the printed wiring board 10 by the engaging portion 16 of the intermediate gear 11 during assembly work.
This prevents the intermediate gear 11 from falling off. When the set is completed, as shown in FIG. 2, a molded boss 13 formed integrally with the cabinet 2 is inserted into the bearing portion 15 of the intermediate gear 11 and becomes a rotating shaft. The tuning knob 3 is rotatably fixed by rotary shafts 14 and 19 formed integrally with the cabinet 2. The stopper ribs 18 and 21 provided on the cabinet are provided to prevent the tuning knob 3 from wobbling in the axial direction. The rack 8, which is integrally formed with the pointer 9, is configured to mesh with a gear portion 17 of the tuning knob 3 and to be slidably moved by rotating the tuning knob 3. The variable capacitor drum 5 is fixed to the variable capacitor 4 which is soldered and fixed to the printed circuit board 10 with screws 12. In the embodiment, the variable converter drum 5, intermediate gear 11, and tuning knob 3 are lined up in a straight line, but it is not necessary to line them up in a straight line as long as the meshing of the gears is reliable. The order of assembly of such a dial device is to insert the tuning knob 3 into the rotating shaft 19 while engaging the rack 8. Next, the engaging portion 16 of the intermediate gear 11 is inserted into the through hole 24 provided in the printed wiring board 10 and moved in the direction of the engaging hole 23 . Engagement hole 23
The outer shape is designed to be slightly larger than the rotating shaft 22 of the intermediate gear 1 and smaller than the engaging portion 16.
