PROBLEM TO BE SOLVED: To provide a keyboard device of an electronic musical instrument in which the assembly of a massive body into a supporting member is smoothly performed and the rotation of the body is smoothly done after the assembly. SOLUTION: The guided section used during the key operation and the insertion against a supporting member 200 of a massive body 300 is provided at the place which is separated from the rotation supporting point of the body 300. The guiding section used during the key operation and the insertion against the body 300 of the member 200 is provided at the place corresponding to the member 200 of the body 300. Moreover, the guiding mechanism used during the key operation and the insertion against the member 200 of the body 300 is provided at the place which is separated from a rotation fulcrum 311 of the body 300 and the guiding mechanism during the insertion of the body 300 acts as the guiding mechanism used during the operation of the body 300. Furthermore, the guiding piece used during the insertion of the body 300 is composed of an elastic piece 211. Moreover, the operation guided section of the body 300 is also used as the insertion guided section. |
