<p><P>PROBLEM TO BE SOLVED: To certainly prevent generation of end lock in a seat belt retractor. <P>SOLUTION: The seat belt retractor is provided with: a spindle wound with a webbing; a lock dock 20 for locking rotation in a webbing drawing out direction of the spindle 1; a steering disc 40 relatively rotatably supported on the spindle 1 and operating the lock dock 20 by generating rotation delay relative to the spindle 1; a ratchet wheel 30 relatively rotatably supported on the steering disc 40 and locking the rotation when a vehicle body acceleration sensing means 110 is operated; and a control lever 60 pivotably pivotally supported on the steering disc 40, allowing relative rotation of the steering disc 40 and the ratchet wheel 30 by releasing bonding of the steering disc 40 and the ratchet wheel 30 at completion of rolling-up of the webbing and engaged with the spindle 1 and the steering disc 40 so as to integrally rotate them. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
