<P>PROBLEM TO BE SOLVED: To provide a key support structure enabling the rotational operation of a key in a stable state by preventing rolling of the key, and a keyboard musical instrument. <P>SOLUTION: The key support structure includes: a key support portion 5 including a pair of support pieces 30 standing on a keyboard chassis 1 and a pair of shaft parts 31 provided so as to face the pair of support pieces 30 respectively; and a key attachment portion 28 including an insertion part 32 provided in a key and inserted between the pair of support pieces 30, shaft holes 33 provided in the insertion part 32 and having the pair of shaft parts 31 fitted thereto, and a pair of holding parts 34 provided in the insertion part 32 and holding respective edges of the pair of support pieces 30 therebetween. Consequently, the pair of holding parts 34 can prevent the pair of support pieces 30 from spreading apart from each other, so that the pair of support pieces 30 can be surely prevented from spreading apart from each other though, when the key is depressed, load is applied to the pair of support pieces 30 of the key support portion 5 by the key in a direction in which the pair of support pieces 30 spread apart from each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
