To prevent an axial gap of a neck section and a deflecting yoke in case that the deflecting yoke is fixed by binding tight to the neck section of a cathode-ray tube.

With respect to the deflecting yoke 3 for the cathode-ray tubes which is constituted with two or more arc pieces 50 which have a predetermined gap in order to enclose the neck section 2 of the cathode-ray tube 1 and to carry out positioning and fixing at this neck section 1, and a band 8 which is equipped in a peripheral section of the arc pieces 50 which is formed in an approximately C-character form with a screw tightening section 9 for fixing by tightening, the length of the gap 50g near the tightening section 9 of the band 8 among the gaps which are made by the two arc pieces, which adjoin each other, of two or more above arc pieces 50, is made smaller than the gap length which is made by the other arc pieces.
