PURPOSE:To prevent the error displacement of a cam plate, i.e., the error memory of a regulator, by separating the link between the cam plate and the manual tuning part after starting the suppressing action of the regulator when the operation lever is pushed in. CONSTITUTION:When the operation lever 10 is pushed in for memory of the desired station, both the push-button plate 12 and the sliding plate 13 slides in a body. The cam plate 29 touches the regulator 25, and the regulator 25 is turned gradually to reach the desired position. When the push-button 11 is pushed furthermore, only the plate 12 slides. Thus the projected pin part 13a moves forward and touches the tilt edge 14a to be stopped. Meanwhile the convex part 22a of the lock cam plate 22 moves forcibly onto the upper surface of the bridge 27c of the suppression spring plate 27 to clamp the regulator 25 to the desired position. The plate 12 is shifted in a slight distance, and thus the cam hole 15 moves to touch the rotary bar 24. Thus the bar 24 starts turning by the tilt part 15c. In this moment, the convex part 24a presses the cam hole 33 of the clutch lever plate 32, and accordingly the cam plate 29 is put under the low-load sliding state. |
