PURPOSE:To form a roller so as to prevent its V-groove from dislocating a rope even if it is loosened, in the case of a rope driven device used for arm driving or the like of a linear tracking player. CONSTITUTION:The numeral 5 is a roller shaft, 6 a roller, 7 a rope and 8 a stopper ring made of nylon or polycarbonate press fitted to the roller shaft 5. The rope 7, if it is loosened due to some cause, is moved deflecting from a V-groove of the roller 6 but never dislocated from the V-groove of the roller 6 because a clearance between the roller 6 and the stopper ring 8 is formed smaller than a diameter of the rope 7. |
