By the way, in the present invention, the remote control wire 21 is pulled up via the switching arm 37, so when the capacity switching lever 27 is operated, the tension on the remote control wire 21 due to the springs 19 and 20 is directed in the operating direction of the capacity switching lever 27. Since the force is applied in a direction substantially perpendicular to the operating direction, the operation of the capacity switching lever 27 is extremely smooth and smooth, and the tension of the remote control wire 21 causes the capacity switching lever 27 to be moved at each capacity switching position. Locking protrusion 3
1 and the locking groove 32 of the support fitting 29 will not fall off, and each capacity switching state can be reliably maintained. By connecting them with a remote control wire, it is possible to maximize the effect that the two can be related regardless of the arrangement of parts within the instrument.
