<p>PURPOSE:To achieve the simplification of mechanism and reduction of production cost by providing a pedal engaging to plural string vibration control mechanisms oscillatably in vertical and horizontal directions and sellectively operating respective functions by way of this pedal. CONSTITUTION:When a pedal 38 is treaded right under, a damper pedal mechanism actuates by being pulled by a wire 41. When the foot is released from the pedal 38, said operation stops. Next, to operate a muffler pedal mechanism in order to weaken the play sounds, the pedal 38 is treaded right under to engage the pedal 38 to the collar 34a of the actuating shaft 34, after which the pedal is moved in a horizontal direction, then permanent magnet 35 is attracted to a plate 33 and even if the foot is released from the pedal 38, this state is maintained. To release the muffler pedal mechanism, the pedal 38 while being held treaded is turned slightly strongly in the horizontal direction to release the attraction force of the magnet 35, after which the foot is released from the pedal 38 and this releases the mechanism.</p> |
