<p><P>PROBLEM TO BE SOLVED: To provide a webbing take-up device that may prevent entering of an end-lock state when a spool rotates in the pull out direction on rebound just after completion of taking up of the webbing belt, and prevent or effectively suppress occurrence of end-lock when the spool rotating in the take-up direction is stopped. <P>SOLUTION: A restriction weight 94 is provided on a V gear 66. The restriction weight 94 moves in the pull out direction relative to the V gear 66 by acceleration when the V gear 66 is rotated in the take up direction, and furthermore, the restriction weight pivots about a support pin 98 under centrifugal force due to rotation of the V gear 66 and attains a contact position. In such a state, even if the inertial mass 84 attempts to displace toward the lock activation direction, the restriction weight 94 interferes with the inertial mass 84 and restricts displacement of the inertial mass 84 toward the lock activation direction. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
