Abstract: A support structure is provided for supporting a sound board of an upright piano. A peripheral portion of the sound board is securely fixed to a sound board bearing shim, which is securely fixed to a back frame. The back frame is constructed by a plurality of posts, beams and a bottom sill. A pin block is attached to an upper portion of the main body of the upright piano above the sound board bearing shim. A support member is provided between the pin block and back frame and is made of the material having a high rigidity. An extending portion extends downwardly from a lower end of the support member. A front surface of the extending portion is attached to an upper portion of the sound board bearing shim. Herein, a thinned portion is formed by cutting a back portion of the extending portion. The extending portion is formed as an integral part of the support member but is different from the support member in thickness. So, the extending portion separates from the back frame.
