Cable reel having inner cases

摘要

A cable reel includes a stationary member forming an outer cylinder and a movable member forming an inner cylinder and rotatably coupled to the stationary member. A flat cable is accommodated in an annular space defined by the stationary and movable members. First and second inner cases that accommodate bus bars are attached to opposite ends of the flat cable. The first and second inner cases are fixed in first and second inner case containing portions provided in the movable and stationary members, respectively. A first protection rib extends from an end surface of a cable outlet portion of the first inner case. The first protection rib includes an arcuate inner peripheral wall and an arcuate outer peripheral wall. The arcuate outer and inner peripheral walls are opposed to each other to define a cable threading path between them.
