PROBLEM TO BE SOLVED: To provide a keyboard device with which a coil spring is easily mountable in a predetermined position between chassis and key at the time of mounting the key to the chassis. SOLUTION: A rib 74 is formed at the chassis 70 of the keyboard device 60 and a wall 100 for preventing the fall of the spring is formed at the key 90. The fall of the coil spring 110 is prevented by the rib 74 and the wall 100 for preventing the fall of the spring. A second projecting part 98 is intruded into the other end 114 of the coil spring 110, by which the key 90 is exactly and easily mounted at the chassis 70. |
