Abstract

A rotating connector includes a cable accommodation chamber formed between an outer case and an inner case in their radial direction, a flexible flat cable housed in the cable accommodation chamber, and multiple idlers housed in the cable accommodation chamber. The idlers are rotatably provided in a direction of an annular slidable member. The idlers are rotatable on their own axes. The flat cable is wound on an inner periphery of the outer case and an outer periphery of the inner case by way of a reversed portion of the flat cable. The flat cable is wound thereon in opposite directions. The idlers are pivotally supported by the slidable member so as to change a space between the idlers and the inner case and a space between the idlers and the outer case depending on winding of the flat cable.

First claim

What is claimed is:

1. A rotary connector comprising:
a cylindrical outer case;
a cylindrical inner case housed in the outer case, the inner case being rotatable relative to the outer case and at a radial interval between the outer case and the inner case forming a cable accommodation chamber;
an annular slidable member rotatably disposed in the cable accommodation chamber;
a plurality of support spindles disposed circumferentially spaced apart on the annular slidable member…
