PURPOSE:To facilitate the assembling to a device main body by interposing a printed circuit board equipped with a tuning variable element between 1st, 2nd brackets of a dialer and coupling the shaft of the tuning variable element with a pulley so as to make the size of the entire receiver small. CONSTITUTION:A rope 7 is wound on a shaft 3' of a channel selection knob 3, engaged with a pointer 6 and a pulley 4 and guided by 3 rollers 5. In turning a channel selection knob 3, the rope is paid off by a friction between the shaft 3' and the rope 7, the pointer 6 is moved and the pulley 4 is driven at the same time, and a locking hole 4' for the variable capacitor shaft is made to the pulley 4. Moreover, the screw hole 1' for mounting is made to the bracket. The bracket 1 completed as a subassembly is mounted with the variable capacitor locking hole 4' and the variable capacitor shaft 9' in combination. In turning the channel selection knob 3 in this state, the pulley is driven and the variable capacitor shaft is driven at the same time to apply channel selection tuning.
