PROBLEM TO BE SOLVED: To provide a keyboard device of an electronic musical instrument capable of preventing an abutting member from being peeled or falling off from an abutting member holding part by reinforcing fixation of the abutting member holding part and the abutting member, while improving working efficiency when fixing the abutting member to the abutting member holding part.SOLUTION: A key 2 and a hammer 3 are supported in a frame 4 so as to freely turn in accordance with key pressing or key releasing operation by a player. Hammer stoppers 5 and 6, and a key auxiliary stopper 7 are fixedly held in holding parts 42a1, 44a and 41c1 provided in the frame 4, and abut on the key 2 and the hammer 3. The frame 4 is injection-molded by inserting the hammer stoppers 5 and 6 and the key auxiliary stopper 7 in a metallic mold. Thus, a fusion layer formed by melting a part of resin composing the frame 4 to permeate into the hammer stoppers 5 and 6 and the key auxiliary stopper 7, and then solidifying it is provided between the hammer stoppers 5 and 6, the key auxiliary stopper 7 and the frame 4. The hammer stoppers 5 and 6 and the key auxiliary stopper 7 are fixedly held on the frame 4 by the fusion layer. |
