전동식 파워 스티어링 장치용 축 연결 기구(1)는, 회전축(2)에 연결된 연결 베이스체(3)와, 회전축(4)에 연결된 연결 베이스체(5)와, 두 연결 베이스체(3 및 5)를 통해 회전축(2)과 회전축(4)의 사이에 배치되어 있음과 동시에 회전축(2)의 축심(O)을 중심으로 한 R방향 회전을 회전축(4)에 전달하는 한 쌍의 강성의 회전 전달 부재(6 및 7)로 이루어지는 회전 전달 부재(8)와, 회전 전달 부재(6 및 7) 사이에 배치되어 있음과 동시에 회전 전달 부재(6 및 7)에 축방향에서 겹쳐 맞춰져 회전 전달 부재(6 및 7)에 결합된 탄성 부재(9)와, 한 쌍의 회전 전달 부재(6 및 7)를 서로 결합하는 결합 수단(10)을 구비하고 있다. A shaft coupling mechanism 1 for an electric power steering apparatus includes a coupling base body 3 coupled to a rotating shaft 2; a coupling base body 5 coupled to a rotating shaft 4; a rotation transmitting member 8 constituted by a pair of rigid rotation transmitting members 6 and 7 disposed between the rotating shaft 2 and the rotating shaft 4 through both coupling base bodies 3 and 5 and adapted to transmit the rotation of the rotating shaft 2 in an R direction about an axis O to the rotating shaft 4; an elastic member 9 interposed between the rotation transmitting members 6 and 7 and coupled to the rotation transmitting members 6 and 7 in such a manner as to be axially superposed on the rotation transmitting members 6 and 7; and a coupling means 10 for coupling the pair of rotation transmitting members 6 and 7 to each other.
