PROBLEM TO BE SOLVED: To provide a shaft connecting mechanism for an electric power steering device capable of avoiding a strike in radial direction between a rotating shaft and a rotation transmitting body and restricting occurrence of irregular noise giving uncomfortable steering feeling to a driver.SOLUTION: A shaft connecting mechanism 1 for an electric power steering device comprises a connecting base body 3 connected to a rotating shaft 2; a connecting base body 5 connected to a rotating shaft 4; a rotation transmitting body 8 having a pair of rigid rotation transmitting members 6 and 7 arranged between the rotating shaft 2 and the rotating shaft 4 through both connecting base bodies 3 and 5 so as to transmit a rotation in a direction R around an axis center with an axis line O of the rotating shaft 2 being applied as a center to the rotating shaft 4; and an elastic member 9 arranged between the rotation transmitting members 6 and 7 in an axial direction X, overlapped on the rotation transmitting members 6 and 7 in the axial direction X and held between the rotation transmitting members 6 and 7.SELECTED DRAWING: Figure 1
【課題】回転軸と回転伝達体との径方向の衝突を回避でき、運転者に不快な操舵感覚を与える異音の発生を抑止できる電動式パワーステアリング装置用の軸連結機構を提供すること。【解決手段】電動式パワーステアリング装置用の軸連結機構1は、回転軸2に連結された連結基体3と、回転軸4に連結された連結基体5と、両連結基体3及び5を介して回転軸2と回転軸4との間に配されていると共に回転軸2の軸心線Oを中心とした軸心周りの方向Rの回転を回転軸4に伝達する一対の剛性の回転伝達部材6及び7を有した回転伝達体8と、軸方向Xにおいて回転伝達部材6及び7間に配されていると共に回転伝達部材6及び7に軸方向Xにおいて重ね合わされて当該回転伝達部材6及び7に挟まれた弾性部材9とを具備している。【選択図】図1
