Rotation transmission device

A rotation transmission device comprising:

• an inner member;
• an outer member having an inner peripheral portion disposed outwardly of the inner member;
• a rolling bearing disposed between the inner peripheral portion of the outer member and an end portion of the inner member at one axial end thereof;
• engaging elements disposed between the inner member and the inner peripheral portion of the outer member;
• a clutch mechanism configured to electromagnetically switch the state of the engaging elements between an engageable state in which the engaging elements are capable of engaging with the inner member and the outer member, and an unengageable state in which the engaging elements are incapable of engaging with the inner member and the outer member;
• and
• a first snap ring attached to the inner peripheral portion of the outer member, wherein the rolling bearing includes an inner ring fitted to the end portion of the inner member, and an outer ring fitted to the inner peripheral portion of the outer member, and
• wherein the first snap ring is arranged to restrict movement of the outer ring toward the other axial end,
• wherein the rotation transmission device further comprises:
• a shaft connected to the outer member so as to be rotatable in unison with and coaxially with the outer member;
• and
• a second snap ring attached to the end portion of the inner member so as to be located on the one axial end side of the inner ring,
• wherein the outer member has, at the one axial end thereof, an opening integral with the inner peripheral portion,
• wherein the second snap ring is attachable to the end portion of the inner member through the opening,
• wherein movement of the inner member toward the other axial end relative to the inner ring is restricted by the second snap ring, and
• wherein the shaft is connected to the opening.
