PROBLEM TO BE SOLVED: To simplify assembly work by making it possible to attach a name cover and a door from the backside of a piano handle. SOLUTION: A window hole 252 is upwardly or downwardly located in a central portion of the piano handle 43 and perforated to both sides of the piano handle 43 for the side of an other end portion other than an indicated window 112. The name cover 253 made of transparent material such as an acrylic resin is inserted from the backside of the piano handle 43 into the window hole 252. The door 254 is openably pivoted to a pivoted portion 253e of the name cover 253. The name cover 253 turnably attaching and unitizing the door 254 is arranged to be fixed to the backside of the piano handle 43, so that the assembly work assembling the name cover 253 and the door 254 on the piano handle 43 can be simplified extremely as compared to the conventional structure where the name cover 253 is secured to surface of the piano handle 43 and securing the door 254 to the backside of the piano handle 43. |
