A rotation transmission device is provided in which leakage of magnetism from an armature to a control retainer is reduced, and of which a two-way clutch can be operated accurately and reliably. This device includes a restricting means (60) for restricting the fitting amount between a coupling tube (54) of the armature (51) and a tubular portion (24) of the control retainer (16A) such that a gap is defined between a back surface of the armature (51), with respect to its surface to be attracted to a rotor (52), and an end surface of the tubular portion (24), to prevent leakage of magnetism from the back surface of the armature (51) to the end surface of the tubular portion (24) when an electromagnet (53) is energized and the armature (51) is pulled to the rotor (52). |
