PROBLEM TO BE SOLVED: To obtain a structure which can suppress the generation of backlash at each engagement part, and can absorb an alignment error between both shafts, related to a torque transmission member which is engaged with outer teeth and inner teeth arranged at a drive shaft and a driven shaft, respectively, and transmits torque between both the shafts.SOLUTION: A torque transmission member 15 is constituted by combining a pair of torque transmission elements 17a, 17b which are arranged at both sides in an axial direction, and an intermediate element 18 which is arranged at an intermediate part in the axial direction. An elastic tooth part 28 which is elastically engaged with outer teeth without causing wobbling is arranged at an internal peripheral face of the intermediate element 18. In a state that protrusions 27a, 27b which are formed at the intermediate element 18 are inserted into insertion holes 23a, 23b of the torque transmission elements 17a, 17b, phases related to circumferential directions of a pair of outside-diameter side tooth elements 22a, 22b which are arranged at external peripheral faces of the torque transmission elements 17a, 17b are displaced from each other.SELECTED DRAWING: Figure 2
【課題】駆動軸と被駆動軸とにそれぞれ設けられた外歯と内歯とに噛合して、これら両軸同士の間でトルクを伝達するトルク伝達部材に関し、それぞれの噛合部においてバックラッシュの発生を抑制できると共に、両軸同士の間のアライメント誤差を吸収できる構造を実現する。【解決手段】トルク伝達部材15を、軸方向両側に配置された1対のトルク伝達素子17a、17bと、軸方向中間部に配置された中間素子18とを組み合わせて構成する。中間素子18の内周面に、外歯に対しがたつきなく弾性的に噛合する、弾性歯部28を設ける。又、中間素子18に設けた突起部27a、27bを、トルク伝達素子17a、17bの挿入孔23a、23b内にそれぞれ挿入した状態で、トルク伝達素子17a、17bの外周面に設けた、1対の外径側歯素子22a、22b同士の円周方向に関する位相をずらす。【選択図】図2
