ABSTRACT:
A torque limiting device for a reel turntable can obtain a stable limiting torque even when an ambient temperature or speed is changed and also can prevent a tape from being damaged when a tape path is fluctuated. First and second magnets are disposed in such an opposing relation as to sandwich therebetween a magnetic plate of a limiting gear from both surfaces thereof and magnetic poles are magnetized on the opposing surfaces of the two magnets which repulse one another.
