<p>PROBLEM TO BE SOLVED: To attain a general-purpose shieve, using a conventional urethane shieve by coupling a first shieve and a second shieve through a first coupling rod and a second coupling rod whose length to a latching part are different respectively and coupling a first shieve and a second shieve through a third coupling rod. SOLUTION: A first shieve 1 and a second shieve 2, conventional urethane shieve are coupled through a third coupling rod 5. A first coupling rod 3 and a second coupling rod 4, whose length to a latching part 7 are different respectively, are set so that the shorter one is on an engine area side. As a result, the length of contact for the first shieve with a wire 6 is longer than that of the second shieve with the wire 6, and the length of contact of a shieve (the second shieve) on a drum area side having much effect on wire torsion can be reduced, thus wire torsion can be prevented. Various wires can be applied with this, because no narrow grooves are used, thereby attaining general-purpose shieve.</p> |
