Abstract

PURPOSE: To enable to deliver the stable and smooth torque without being subjected to the effect of ambient environment and time aging, by delivering the rotary torque of pulley to the reel stand with magnetic force.
CONSTITUTION: When the pulley 2 is turned via the belt, the magnet 3 turns also, and the magnetic flux from the magnet 5 to the iron plate 6 changes and eddy current is caused to the iron plate 6. Thus, torque is exerted to the iron plate 6 with the eddy current and the magnetic flux from the magnet 5, and the reel stand 3 rotates with a speed more or less delayed to the rotary speed of the pulley 2. This delay is determined with the distance between the iron plate 6 and the magnet 5 and the magnet force of the magnet 5. Thus, since the torque delivery part is of non-contact type, stable torque delivery can be made without being subjected to the effect of environment and time aging.
