To enable easier processing of a core of an electromagnet and a member which moves close to or separates from the core in an electromagnetic clutch included in a rotation transmission device.SOLUTION: A rotation transmission device includes: a two-way clutch 50 which causes an inner member 30 and an outer member 21 to be engaged with or disengaged from each other; and an electromagnetic clutch 40 which controls engagement or disengagement of the two-way clutch 50. The electromagnetic clutch 40 includes: an armature 51 which is prevented from rotating relative to a retainer 54 and supported in a manner that enables movement in an axial direction; an electromagnet 44 having a core 41 facing the armature 51 in the axial direction, and an electromagnetic coil 42 held by the core 41; and a separation elastic member 57 which biases the armature 51 in a direction away from the core 41. A facing surface 41x of the core 41 facing the armature 51 is formed with a recessed part 46 which houses the separation elastic member 57.SELECTED DRAWING: Figure 2

    【課題】回転伝達装置が備える電磁クラッチにおける電磁石のコア及びそれに切離する部材の加工を容易にする。【解決手段】内方部材30及び外方部材21を係合及び係合解除する2方向クラッチ50と、2方向クラッチ50の係合及び係合解除を制御する電磁クラッチ40とを備え、電磁クラッチ40は、保持器54に対して回り止めされて軸方向へ移動自在に支持されたアーマチュア51と、アーマチュア51と軸方向で対向するコア41とコア41に保持される電磁コイル42とを有する電磁石44と、アーマチュア51をコア41から離反する方向に付勢する離反用弾性部材57を備え、コア41のアーマチュア51との対向面41xに、離反用弾性部材57を収容する凹部46が形成されている回転伝達装置とした。【選択図】図2
