PROBLEM TO BE SOLVED: To provide a rotary connector capable of avoiding complication on a structure due to a large number of rotator rotations.SOLUTION: A rotary connector 1 is equipped with: a stator 8 on a fixed side; a rotator 9 on a rotating side; and an intermediate member 32 disposed between the stator 8 and the rotator 9. The rotary connector 1 is equipped with a gear mechanism 31 dividing multiple rotations of the rotator 9 into small rotations. In the gear mechanism 31, a first gear portion 41 formed on the rotator 9 is engaged with a fourth gear portion 44 of the intermediate member 32 through a second gear portion 42 and a third gear portion 43 with small diameters. An electric connecting portion 24 is attached so as to traverse the stator 8, the intermediate member 32, and the rotator 9. While the rotator is rotated, a number of rotations of the intermediate member 32 becomes smaller than a number of rotations of the rotator 9, so that the winding amount of the electric connecting portion 24 is suppressed to be small during winding.SELECTED DRAWING: Figure 3

    【課題】ロテータ回転の多さによる構造上の複雑化を回避することができる回転コネクタを提供する。【解決手段】回転コネクタ1は、固定側のステータ8と、回動側のロテータ9と、ステータ8及びロテータ9の間に配置された中間部材32とを備える。回転コネクタ1は、ロテータ9の多回転を少回転に分割するギヤ機構31を備える。ギヤ機構31は、ロテータ9に形成された第1ギヤ部41が、小径の第2ギヤ部42及び第3ギヤ部43を介して、中間部材32の第4ギヤ部44に噛み合わされている。電気接続部24は、ステータ8、中間部材32及びロテータ9を横断するように取り付けられている。ロテータ回転時、ロテータ9の回転数よりも中間部材32の回転数が少なくなることにより、電気接続部24の巻き取り量が途中で少なく抑えられる。【選択図】図3
