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
