ツトロール。 A shaft is fixed to a permanent magnet member with a constant cross-sectional shape and a plurality of magnetic poles extending in the axial direction on the outer peripheral surface, and a hollow cylindrical shape is formed through support members provided at both ends of the shaft. In the magnet roll, the sleeve is provided coaxially and freely rotatably with the shaft and the permanent magnet member, and an annular recess is provided at the outer peripheral edge of the support member, and an annular recess is provided near the end of the support member and the end surface of the sleeve. A magnetic roll is characterized in that a gap is formed between the support member and the sleeve, and the support member and the sleeve are fixed together by filling the recess and the gap with an ultraviolet curing adhesive having anaerobic curing properties. .
