<p>PROBLEM TO BE SOLVED: To facilitate the insertion of a turning member such as a key or mass body, to a supporting member. SOLUTION: This keyboard device has an elastic piece 13 disposed integrally on a turning member 1 side. The turning fulcrum point 12 of the turning member 1 is pressed by the elasticity of this elastic piece 13 throughout the time when the turning member 1 is held inserted to the supporting member 2 and at the time of man-key touch and at the time of key touch so that the this fulcrum part is kept pressed to the turning supporting part 22 of the supporting member 2 at all times. Further, the keyboard device is provided with a second elastic piece separate from the elastic piece described above and is provided with such a section where this elastic piece is intruded into a permissible space (nn) formed by the turning fulcrum part of the key and the turning supporting part of the supporting member to prohibit the sufficient displacement of the elastic piece at the time of insertion and removal of the key after the insertion of the key into the supplying member.</p> |
