Wind instrument with link mechanism for transmitting lever action to rotary valve unit or key
摘要：
A wind instrument is equipped with rotary valve units or keys for changing the length of vibrative air column, and a link mechanism transmits a lever action to the rotary valve unit or the key, wherein a joint (13a) incorporated in the link mechanism comprises a shaft member (13aa) having an external thread (13ag) and coupled with a manipulating lever (14), an adjustable screw member (13ac) with an internal thread (13am), a tubular member (13ab) actuating the rotary valve unit or the key and retained by the adjustable screw meshed with the external thread, and an elastic member (13ad) inserted between a bottom surface of the tubular member and a leading end of the external thread portion so that gaps (G11/ G12) on both sides of the tubular member are adjustable, thereby allowing the tubular member to smoothly rotate.
