<p>PROBLEM TO BE SOLVED: To prevent generation of abnormal sound caused by contact between a rotor of a cable reel and a case when the rotor is rotated, and to smoothly rotate the rotor. SOLUTION: A rotor 2 is installed in an upper opening of a cylindrical case 1, while a flat cable 4 is accommodated within an annular hollow part formed between the case 1 and the rotor 2. In this cable reel, a circular lock member 10, which is fixed on an inner face of a circumferential wall along an end edge of the upper opening the case 1, is made of a metal material or an insert- molded metal ring. The rotor 2 is installed in the case 1 such that the lock member 10 is rotatably fitted in the cutout formed on an outer circumferential end face of the rotor 2.</p> |
