PROBLEM TO BE SOLVED: To prevent an aroma of an aromatic agent in a container from being leaked outside while a key is not pressed in a keyboard instrument that can produce a musical sound as well as an aroma when the key is pressed.SOLUTION: When a white key 15 is not pressed, a deep surface of a dent part 22 for closing an aromatic agent container provided below a rear end part of the white key 15 is in contact with a top surface of a periphery of a dent part 35 for aromatic agent accommodation of an aromatic agent container 33. In this situation, the dent part 35 for aromatic agent accommodation of the aromatic agent container 33 is blocked by the deep surface of the dent part 22 for closing the aromatic agent container of the white key 15. As a result, leakage of an aroma of the aromatic agent 42 inside the dent part 35 for aromatic agent accommodation of the aromatic agent container 33 can be prevented while the white key 15 is not pressed.SELECTED DRAWING: Figure 2 |
