PURPOSE:To engage the gear of a dial operating part with a variable capacitor gear accurately and to facilitate assembling operation by fitting a chassis which is equipped with the dial operating part to the fitting part of a printed wiring board provided on the basis of the fitting part of a variable capacitor. CONSTITUTION:The dial chassis 4 of the dial device is provided with the dial operating part consisting of a knob 5, gear 5a, pointer rack 6, etc. The variable capacitor gear 1 is clamped to the variable capacitor 2, the projection 7b of the variable capacitor 2 is inserted into the hole formed in the printed wiring board 13, and the variable capacitor 2 is fixed to the wiring board 13. A main body chassis 3 is fixed to the wiring board 13 in one body. Further, the dial chassis 4 is fitted to the fitting part of the wiring board 13 on the basis of the projection 7b of the variable capacitor 2. The gear 5a of dial operating part is engaged accurately with the variable capacitor gear 1a and the assembling operation of the dial device is facilitated. |
