置。[Claims for Utility Model Registration] A take-up reel that urges the webbing in the winding direction and winds the webbing, and a webbing that rotates integrally with the take-up reel when the webbing pull-out acceleration is below a predetermined value. an inertial sensing means that operates with respect to the take-up reel when the pull-out acceleration exceeds a predetermined value; a cup member that rotates in conjunction with the take-up reel due to the operation of the inertial sensing means; and a cup member that rotates in conjunction with the take-up reel. In a seatbelt retractor with an emergency lock release mechanism, the seatbelt retractor includes a locking means for stopping the rotation of the takeup reel in the ebbing drawing direction when receiving a movement, and a clutch means for continuing interlocking between the cup member and the locking means, The clutch means includes a cam member disposed on a shaft separate from the cup member so as to rotate in conjunction with the rotation of the take-up reel, and having a cam surface that is displaced as the take-up reel rotates; The cup member contacts the cam surface and follows the displacement of the cam surface, and when the webbing is pulled out by a predetermined amount or more from the take-up reel, the cup member swings relative to the cup member according to the accompanying displacement of the cam surface and engages with the cup member. and a rocking lever that brings the locking means into an interlocking relationship, and the rocking lever is further rocked by rotation of the cup member after engagement with the cup member to actuate the locking means. A seatbelt retractor with an emergency lock release mechanism.
