PROBLEM TO BE SOLVED: To provide a rotary connector which does not require an extra force at insertion of a rotary stopper, and is hard to fall off even when an impact is applied to the rotary stopper from outside after the insertion.SOLUTION: A rotator stopper 30 connects a rotator and a fixing body of a rotary connector to tentatively fix them at a neutral position of a cable. The rotator stopper 30 comprises: a snap-in part 31 including deformable parts 34A and 34B which can be elastically deformed and engagement parts 33A and 33b; and a notch part 38 for folding a base end side of the rotator stopper 30. A rotator stopper attachment part 40 of the fixing body includes: lock parts 42A and 42B which lock the engagement parts 33A and 33B of the snap-in part 31; and a deformation regulating part 45 which bends in the middle of insertion of the rotator stopper 30 to avoid the snap-in part 31, and is positioned between portions of the snap-in part 31 after the insertion to regulate the deformation of the snap-in part 31 in the direction to fall off.SELECTED DRAWING: Figure 12
【課題】回転体ストッパの挿入時には余分な力を必要とせず、かつ挿入完了後には回転体ストッパが外部からの衝撃を受けても外れ難い回転コネクタを提供する。【解決手段】回転体ストッパ30は、回転コネクタの回転体と固定体を連結して、ケーブルの中立位置で仮固定する。回転体ストッパ30は、弾性変形可能な変形許容部34A,34Bと係合部33A,33Bとを有するスナップイン部31と、回転体ストッパ30の基端側を折り取るための切り欠き部38と、を備える。固定体の回転ストッパ装着部40は、スナップイン部31の係合部33A,33Bを係止するための係止部42A,42Bと、回転体ストッパ30の挿入途中には撓んでスナップイン部31を回避し、挿入完了時にはスナップイン部31の間に位置してスナップイン部31の外れ方向への変形を規制する変形規制部45と、を有する。【選択図】図12
