ABSTRACT:
An improved tuning device includes a housing which a least partially encloses a worm, pinion gear and shaft or string post. The housing includes a main member which encloses the worm and an extension member which is formed separately from the main housing member and encloses the shaft. The extension housing member has a head end portion which is disposed in the main housing member and a shank portion which extends outward from the head end portion. The shank portion of the extension housing member is indented to engage a groove in the shaft. When the tuning device is to be assembled, the extension housing member is deformed into engagement with the groove in the shaft and is then connected with the main housing member. When the extension housing member is to be connected with the main housing member, the extension housing member, shaft and pinion are inserted through an opening in an outer side of the main housing member and then through an opening in an inner side of the main housing member.
