Abstract: An engagement and disengagement device used in a seat belt retractor includes a first rotating member and a second rotating member configured to be coaxial, and a transmission member disposed between the first and second rotating members. The first rotating member defines an engagement portion on a radial inner surface thereof, and the distance from the engagement portion to an axis of rotation gradually increases in a first direction of rotation. The transmission member can rotate between an engagement position and a non-engagement position relative to the first rotating member.

Abstract: An engagement and disengagement device used in a seat belt retractor including a first rotating member capable of being driven to rotate about a rotation axis thereof, a second rotating member provided coaxially with the first rotating member and connected to a reel of the seat belt retractor in an anti-torsion manner, and a transmission member provided between the first and second rotating member. The first rotating member is capable of transmitting torque to the second rotating member by means of the transmission member. The transmission member includes a holder and a transmission element in the holder. A first elastic component elastically holds the transmission element by radially exerting a force that enables the transmission element to be located away from the first or the second rotating member, and the first elastic component is integrated on the holder.
