PROBLEM TO BE SOLVED: To provide a power transmission joint which suppresses the generation of abnormal sound due to contact hammering on a power transmission surface.SOLUTION: A power transmission joint 20 includes: a first rotation element 23 and a second rotation element 24 in which respective engagement protrusions 29, 30 are alternately arranged in the rotation direction Z; and an intermediate element 25 which connects both rotation elements 23, 24 so as to permit torque transmission. The intermediate element 25 contains a power transmission part 32 interposed between the engagement protrusions 29, 30 of both rotation elements 23, 24. The power transmission part 32 contains a pair of power transmission surfaces 32a, 32b engaged with power transmission surfaces 29a, 30a of both engagement protrusions 29, 30. The intermediate element 25 is a unit made by overlapping a pair of end part layers (resin layers 41) opposed in the axial direction X and an elastic layer (rubber layer 42) interposed between the end part layers to each other. The pair of power transmission surfaces 32a, 32b of the power transmission part 32 are formed by a part of the elastic layer (rubber layer 42).

    【課題】動力伝達面での接触打音による異音の発生を抑制する動力伝達継手を提供する。【解決手段】動力伝達継手20が、互いの係合突起29,30を回転方向Zの交互に配置する第1回転要素23及び第2回転要素24と、両回転要素23,24をトルク伝達可能に連結する中間要素25とを備える。中間要素25が、両回転要素23,24の係合突起29,30間に介在する動力伝達部32を含む。動力伝達部32は、両係合突起29,30の動力伝達面29a,30aに係合する一対の動力伝達面32a,32bを含む。中間要素25は、軸方向Xに対向する一対の端部層(樹脂層41)と、端部層間に介在する弾性層(ゴム層42)とを重ね合わせたユニットである。動力伝達部32の一対の動力伝達面32a,32bは、弾性層(ゴム層42)の一部により形成される。【選択図】図3
