PROBLEM TO BE SOLVED: To make addable a sudden change to force information, to make arbitrarily operable the point of time of rising, and to make performable a playing input of full of changes. SOLUTION: A metal plate 13 is disposed on a gondola 12 moving on a potentiometer 11. A distortion gauge 14 is attached to a part of the metal plate 13 and a cylinder 16 is fitted to a support 15 at the center part of the metal plate 13. An elastic material 18 is disposed between the step part 16c of the cylinder 16 and the metal plate 13, the cylinder 16 and a knob 17 are floated with respect to the metal plate 13 and a clearance is formed between the projection piece 16b of the cylinder 16 and the metal plate 13. At the time of displacing the cylinder 16 slightly downwards, the displacement of the metal plate 13 is made smaller than the displacement of the cylinder 16 by the elastic deformation of the elastic material 18. At the time of applying a pressurizing force to a certain degree, the projection piece 16b of the cylinder 16 is abutted to the metal plate 13 and the displacement of the cylinder 16 is turned to the displacement of the metal plate 13 as it is. |
