<p>PURPOSE:To reduce the number of parts for the reel driving device and to enhance their precision and assemblability. CONSTITUTION:A limiter gear 5, a direct gear 4, a felt 6 and a pendulum arm 15 are arranged between a thrust spring 7 and an output gear 20. The gears 5 and 4, the felt and the arm are energized to the side of the gear 20 by the spring 7. Under a limiter mode, the gear 5 is meshed with a driving gear, and this rotational force is transmitted via the gear 5, the felt and the gear 4 to the gear 20. Under a direct mode, the gear 4 is meshed with the driving gear, and this rotational force is transmitted via the gear 4 to the gear 20. The arm is rotated by friction force during rotation of the gear 20. Since the spring 7 is also served as a spring for oscillating the arm, a dedicated oscillating spring, etc., can be dispensed with, thus reducing the number of parts.</p> |
