<P>PROBLEM TO BE SOLVED: To provide a keyframe front of a keyboard instrument, which allows firmer adhesion of keyframe moldings to each other and allows the adhesion work to be quickly performed. <P>SOLUTION: The keyframe of a keyboard instrument is constituted by mutually coupling a plurality of keyframe moldings 51 made of a synthetic resin, so as to extend in a lateral direction and holds front pins engaged with front end parts of keys, in a standing state. Each of the plurality of keyframe moldings 51 includes a body portion 52 extending in the lateral direction and having a plurality of front pins stood thereon and coupling portions 53 and 54 provided so as to project from at least one of left and right end parts of the body portion 52 and screwed in a state of overlap and contact with each other in order to couple adjacent keyframe moldings 51 and 51 to each other. A groove 55 allowing an adhesive to flow thereinto from the outside is formed on at least one of contact surfaces being in contact with each other of, the coupling portions 53 and 54 of adjacent keyframe moldings 51. <P>COPYRIGHT: (C)2013,JPO&INPIT |
