Abstract
To provide a key of a keyboard device in which fitting positions of wooden boards can easily be adjusted, a gap between a key body and the wooden boards is not generated and an appearance due to squeeze-out of an adhesive is not damaged.SOLUTION: A key of a keyboard device includes: a key body 2 which extends in a cross direction by a prescribed length and has an upper surface part 4 and side face parts 5; and wooden boards 3 which are fitted along a part of the side face parts 5. Upper projections 6 which extend along ends, are continuously formed with the upper surface part 4 and project laterally than the side face parts 5 are formed at ends of the side face parts 5 side of the upper surface part 4. Lower support projections 7 which project laterally and are confronted with the upper projections 6 are formed near lower ends of the side face parts 5. Upper faces of the lower support projections 7 become inclined faces S inclining downward toward a tip side. The wooden boards 3 are provided so that upper end faces abut on lower faces of the upper projections 6 and are held between the upper projections 6 and the lower support projections 7.SELECTED DRAWING: Figure 3
