In a dial device having such a configuration, the rack portion 1b of the pointer 1
As shown in FIG. 4, the pitch of the teeth is set to be equal to the pitch of the gear portion 2a of the tuning knob 2 and the pitch of the gear portion 3a of the variable converter drum 3 in the curved state. If they engage inside the curved state 1C, as in the case of FIG. Therefore, the tuning knob 2 and the variable converter drum 3 can be installed at the curved position 1C of the rack portion 1b of the pointer 1. In addition, as shown in FIG. 4 and FIG. 5, when engaging outside the curved state 1C, it is preferable to set it smaller than the tuning knob 2 and the variable converter drum 3.
