Abstract:
A mounting structure for fixing a locking collar to a cable reel rotor, said locking collar including a cancel cam, said mounting structure comprising:a plurality of pairs of securing protrusions and inverted L-shaped securing recesses arranged at a predetermined spaced distance in a peripheral direction on an external peripheral surface on a cylindrically-shaped central axis area of said rotor and on a cylindrical inner peripheral surface of said locking collar, the securing protrusions being arranged on one of said rotor or said locking collar, and the inverted L-shaped securing recesses being arranged on the other of said rotor or said locking collar, wherein the collar is mounted by rotation onto the rotor after inserting the collar onto a lower side of said external peripheral surface; whereby, one pair among the plurality of pairs of securing recesses and securing protrusions are formed as a specific positioning securing recess and specific securing protrusion having circumferential sizes configured to be different from the circumferential sizes of the remaining pairs of securing recesses and securing protrusions, thereby allowing connection at a normal position of said rotor and said locking collar by preventing other securing protrusions from insertion into said positioning securing recess.
