PURPOSE: To provide a magnet belt allowing magnet pieces to be fitted as dense as possible without a bolt protruding to the engaging face with a pulley and unlimited in the number of the engaging teeth of the pulley. CONSTITUTION: A magnet belt is constituted of belt base material 2 made of thermoplastic synthetic resin with one face provided with numerous engaging protrusions 3 to be engaged with a pulley, numerous magnet holding bodies 4 made of the same synthetic resin and rigidly fixed to the other face of the belt base material 2, yokes 5 fixed to the magnet holding bodies 4, and magnet pieces 6 fixed to the yokes 5. Each magnet holding body 4 is disposed in the overlapped position with the engaging protrusion 3 of the belt base material 2. A threaded cylinder 9 extended from the yoke 5 is provided in such a way as to pierce the magnet holding body 4 and belt base material 2 and to reach a thread receiving recession 11 formed at the engaging protrusion 3. A bolt 13 is screwed with the threaded cylinder 9 so that the head part recedes into the thread receiving recession 11, thus fixing the yoke 5 to the belt base material. |
