PURPOSE: A hanger of a roll side cover is provided to adjust the tension, length and height of a wire as well as a roll side cover by the sub housing of a lower part holding part in which a screw joint hole is formed. CONSTITUTION: A hanger(100) of a roll side cover comprises an upper holding part(21), a lower part holding part(22), and an expansion part. The upper and lower holding parts are held by on a roll polisher frame of the upper side. The expansion part mounts the upper holding part in the upper part and the lower holding part in the lower part. The expansion part comprises a cylindrical housing(42), a ring shaft(44), a spring(46), a supporting ring member, and a limited ring(49). The ring shaft is internally mounted in a hollow and moves along the hollow. The ring shaft is downwardly extended from the housing. The spring surrounds the ring shaft. The spring is pressed and contracted by the limited ring when the ring shaft downwardly moves and is elastically restored when the ring shaft upwardly moves. The supporting ring member is mounted in the lower internal housing. The spring is upwardly supported by the supporting ring member. |
