<p>PURPOSE: To facilitate putting in and out of a harmonica and to prevent shaking and jumping out by changing the outside shape of the harmonica. CONSTITUTION: The harmonica 1 is formed to an elliptic shape in front view and the thickness at the central part in the longitudinal direction is maximized. A housing case 30 is composed of a case body 31 and a cover 32 fitted into the aperture of this case body 31. The front view shape of the housing case 30 is the elliptic shape which resembles the front view shape of the harmonica and is slightly larger than this shape. The width in the aperture of the case body 31 is set slightly smaller than the max. thickness at the central part in, the longitudinal direction.</p> |
