Abstract

PURPOSE: To enable a rotary head drum to be readily fixed to a revolving shaft without causing its axial deviation by using a sleeve which has a protrusion.
CONSTITUTION: A sleeve 10 composed of phosphor bronze or other is press-fixed into a hole 2d through which the revolving shaft 9 of a rotary head drum 2 penetrates. In addition, the bottom end of the sleeve 10 is detained to the bearing 1a of a lower guide drum 1. The upper part of this sleeve 10 is formed with an arc form protrusion 10a along its circumference direction. A pair of tightening plates 11 and 12 are fitted onto this protrusion 10a. At the time of mounting the drum 2, the sleeve 10 is fitted onto the revolving shaft 9, thence screws 13 are tightened, by which the tightening plates 11, 12 are finely adjusted in the mutually proximate direction. As a result, even force is applied in the perpendicular direction to the surface of the protrusion 10a, whereby reduction of inside diameter is caused and the drum 2 is fixed to the shaft 9 without displacing the central axis of the sleeve 10.
