To provide a rotary connector device capable of easily and reliably fixing a rotary connector at a neutral position when assembling the rotary connector.SOLUTION: In a rotary connector device having a rotary connector which includes a rotating body and a fixed body which are freely relatively rotatably combined with each other to form an annular space therein, and a cable which is connected to the rotating body at one end thereof and to the fixed body at the other end thereof, and wound and accommodated in the annular space, the rotating body includes an inner gear portion having external teeth which is provided along the circumferential direction of the rotating body, a planetary gear portion that engages with the outer teeth of the inner gear portion, and an outer gear portion that faces the outer teeth of the inner gear portion and has internal teeth that engages with the planetary gear portion. The outer gear portion includes a protruding portion which has a hole portion and outwardly protrudes, and the fixed body includes an extending portion which has a through-hole and extends outwardly. The rotary connector is neutrally positioned at a position where the hole portion of the protruding portion and the through-hole of the extending portion are overlapped with each other in plan view.SELECTED DRAWING: Figure 1
【課題】本発明は、回転コネクタの組み付け時に回転コネクタを中立位置にて容易且つ確実に固定することができる回転コネクタ装置を提供する。【解決手段】互いに相対回転自在に組み合わされ、内部に環状の空間が形成されている回転体及び固定体と、一端が前記回転体に、他端が前記固定体に接続されて、前記環状の空間に巻回されて収容されているケーブルと、を備えた回転コネクタを有する回転コネクタ装置であって、前記回転体に、前記回転体の周方向に沿って設けられた、外歯を有する内側歯車部と、前記内側歯車部の外歯と噛み合う遊星歯車部と、前記内側歯車部の外歯と対向し、前記遊星歯車部と噛み合う内歯を有する外側歯車部と、を有し、前記外側歯車部が、孔部を有する外方向へ突出した突出部を備え、前記固定体が、貫通孔を有する外方向へ延出した延出部を備え、前記突出部の孔部と前記延出部の貫通孔が、平面視にて重ね合わされる位置にて、前記回転コネクタが中立に位置決めされる回転コネクタ装置。【選択図】図1
