Abstract
A topboard support device for a grand piano, in which a topboard prop can be accommodated without placing the same on ribs of a frame. The topboard support device supports a topboard capable of opening and closing the top of a piano body, in an open state, and includes the topboard prop for supporting the opened topboard from below by a tip end portion thereof, and a prop support member for supporting the topboard prop via a base end portion thereof in a manner pivotally movable about vertical and horizontal axes. The topboard prop is pivotally moved by the prop support member between a position for being accommodated in a space between the ribs of the frame and an outer rim, in a substantially horizontal posture, and a position for supporting the topboard, in a posture tilted in a manner rising toward a tip end.
