PROBLEM TO BE SOLVED: To prevent each key from being twisted when assembled. SOLUTION: The keyboard device is equipped with a key 1, a swing support means 2 which is formed integrally with the key and has flexibility and supports the key so that the key freely swings in a key depression direction, a reaction force generating means 10 which gives the key a reaction force corresponding to a key pressing force, a movable-side upper-limit restricting means 13 which is provided to the key, and a fixed-side upper-limit restricting means 14 which restricts the upper limit of the movement of the key when the movable-side upper-limit restricting means abuts. The movable-side upper-limit restricting means 13 abuts against only one place of the fixed-side upper-limit restricting means 14 and the abutting position P between the movable-side upper-limit restricting means and fixed-side upper-limit restriction means is positioned almost on the straight line connecting the reaction force giving position R of the reaction force generating means 10 and the position Q of the swing support means 2 or its prolongation when viewed from above. |
