Abstract (en)
[origin: EP3605522A1] A keyboard weight includes a weight body formed in a cylindrical shape. A groove is formed in a peripheral edge portion of an end face of the weight body, the groove extending along a peripheral edge of the end face, the end face being perpendicular to an axial direction of the weight body, and an outward inner surface of the groove among inner surfaces of the groove slopes toward outside of the weight body from a bottom portion of the groove toward an opening in the axial direction, the outward inner surface facing toward inside of the weight body in the radial direction, and an inclination angle of the outward inner surface is 30° or greater relative to the axial direction.
