Classification: CPC F | IPC F

Claim 0:
1. 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 a first 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 a 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,
wherein the first snap ring is arranged to restrict movement of the outer ring toward a second axial end of the inner member,
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 first axial end the inner ring,

wherein the outer member has, at a first 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 second axial end of the inner member relative to the inner ring is restricted by the second snap ring,
wherein the shaft is connected to the outer member at the opening,
wherein the rotation transmission device further comprises a third snap ring attached to the outer member at the opening,
wherein the shaft includes a telescopically fitted portion coaxially fitted to the opening, and includes an engagement wall axially opposed to the third snap ring, and
wherein movement of the shaft in a pullout direction relative to the outer member is restricted by the third snap ring and the engagement wall.
