PROBLEM TO BE SOLVED: To provide a device which can faithfully reproduce a touch of a plurality of pedals provided in an acoustic piano with a simple structure.SOLUTION: A pedal 10 includes: a spring member 40 constituted of an elastic material which is displaced according to a stroke by a stepping operation of the pedal 10 and imparts a reaction force to the pedal; and a frame 20 having a front wall 21 having an opening 23, a rear wall 22 and a bottom wall 25. The pedal 10 further includes: an operation part 11 operated in a stepping manner; and a fitting part 12 fitted to the frame 20. The operation part 11 is rotated with a point where a rear end vicinity of the fitting part 12 is engaged with an opening 24 of the rear wall 22 as a fulcrum when operated downward from a stationary state of the pedal 40, and is rotated with a point where the vicinity of the fitting part 12 is engaged with an upper end side of the opening of the front wall 21 as the fulcrum when operated upward from the stationary state of the pedal 10. |
