To improve the positional displacement of an inner ring and an outer ring, and to improve the assembling performance of the inner ring and the outer ring.SOLUTION: A shaft connector 100 comprises: a motor-side joint 8 connected to an output shaft 7a; a worm-side joint 6 connected to a worm shaft 2; and a coupling 20 which is arranged between the motor-side joint 8 and the worm-side joint 6, and transmits the rotation torque of the motor-side joint 8 to the worm-side joint 6. The coupling 20 has an inner ring 21, and an outer ring 25 for exposing both end faces of the inner ring 21 in an axial direction, and covering an external peripheral face of the inner ring 21 in a radial direction. The inner ring 21 and the outer ring 25 differ from each other in rigidity, and a fitting protrusion 22f and a fitting recess 26f are formed at the inner ring 21 and the outer ring 25 as fitting concave/convex parts for regulating positional displacement by being fit to each other.SELECTED DRAWING: Figure 3

    【課題】内側リングと外側リングの位置ずれを防止するとともに内側リングと外側リングの組付性を向上する。【解決手段】軸連結器100は、出力シャフト7aに接続されるモータ側ジョイント8と、ウォームシャフト2に接続されるウォーム側ジョイント6と、モータ側ジョイント8とウォーム側ジョイント6との間に設けられ、モータ側ジョイント8の回転トルクをウォーム側ジョイント6に伝達するカップリング20と、を備え、カップリング20は、内側リング21と、内側リング21の軸方向両端面を露出させ、内側リング21の径方向外周面を覆う外側リング25と、を有し、内側リング21及び外側リング25は、剛性が互いに異なり、内側リング21及び外側リング25のそれぞれには、互いに嵌合することで位置ずれを規制する嵌合凹凸部として、嵌合凸部22f及び嵌合凹部26fが設けられている。【選択図】図3
