KEY FOR KEYBOARD MUSICAL INSTRUMENT, AND METHOD FOR MANUFACTURING THE KEY

摘要

A key includes upper, front and side walls each having a flat shape, and a downwardly-opening space. The key includes a first part (e.g., the upper and front walls) normally visible from outside with the key assembled to the keyboard musical instrument; and a second part (e.g., the side walls) normally invisible from outside with the key assembled to the keyboard musical instrument. In molding, a first molding process is performed where resin is poured into a first mold to mold one of the part normally visible from outside and the part normally invisible from outside, and then a second molding process is performed where the one part molded by the first molding process is inserted into a second mold and resin is poured into the second mold so that the other of the parts is molded and thus the upper wall, front wall and side walls are insert-molded.
