PROBLEM TO BE SOLVED: To provide an easy-to-assemble keyboard device with reduced manufacturing cost due to reduced cost of chassis, and also due to the decreased number of components relating to a return spring. SOLUTION: This device 1 is equipped with chassis with chassis 2 which are arranged in the right-left direction, keys 3 which are fitted rotatably to the chassis 2 and arranged in the right-left direction, connecting member 4 and 5 which extend in the right-left direction and mutually connect the plural segments of the chassis, and return springs 6 which are held by the connecting members 5 and energize the keys 3 to return to key release positions. The chassis for one keyboard device are divided into plural segments, which can be manufactured separately, so the chassis are each made smaller in size than that in a conventional case wherein one chassis is manufactured for each keyboard device. |
