PROBLEM TO BE SOLVED: To provide a keyboard device with which the durability of a keyboard is improved without enlarging the full length of the keyboard, a molding machine can be miniaturized in the case of molding by a molding machine, keys can be oscillated comparatively easily in the horizontal direction, the keys can be aligned without pressing strongly the keys to the key guide when the keys are mounted on the body of a musical instrument, the quality of appearance of the keyboard and key touch can also be improved, and furthermore, a mechanical noise can be prevented. SOLUTION: The keyboard device is composed of a plurality of keys 2, a common mounting part 3, and a hinge part 5 to connect the plurality of keys and the common mounting part, and the shape of the cross section of the hinge part in the connection direction is a nonlinear shape (for example, U shape). |
