PROBLEM TO BE SOLVED: To provide a keyboard device for an electronic keyboard instrument whose cushion material selection range which buffers the impulse of a hammer can be enlarged, and by that a desirable touch feeling can be attained, an occurrence of a hammer impulse sound can be prevented, and an after-touch can be detected, and by way of these, the range of performance expression can be enlarged and the quality of the performance can be enhanced. SOLUTION: This device consists off multiple keyboards 3 which are supported by a chassis 2 to freely move around; multiple hammers 4 which are placed for each keyboard 3 and supported by the chassis 2 to freely move around, and move according to the push key of the corresponding keyboard 3; a cushion 12 which is made of elastic material and placed at each hammer 4; a stopper 11 which is placed at the chassis 2 and controls the movement of the hammer 4 by touching the hammer 4 with the cushion 12 in-between. |
