摘要： A damper for an upright piano is provided for improving sound stopping capabilities and consequently improving sequential touching capabilities without adversely affecting a key touch feeling. The damper lever for an upright piano is pressed against a vibrating string to stop the vibration in response to a released key, in order to stop sound which has been generated from the vibrating string. The damper lever comprises a molding molded by a continuous fiber method and made of a thermoplastic resin containing long fibers for reinforcement.

摘要： A back check for a piano is provided for locking a returning hammer in a pivotal movement without fail and for saving the manufacturing cost. The back check is used for locking the hammer in a pivotal movement for returning after it has struck a string to prevent the hammer from rebounding. A back check, disposed at a location at which the hammer is locked, extends in a vertical direction, and has an adhering surface which rises in a central portion thereof in the vertical direction. An under felt is adhered on the adhering surface of the back check body. A sheet-like cushion material, which is adhered to the back check body to cover the under felt, is formed with a locking surface in a predetermined curved shape conformal to the adhering surface for locking the hammer.
