<P>PROBLEM TO BE SOLVED: To enhance the rotation performance and operational capability of a restriction member. <P>SOLUTION: In a webbing take-up device 10, a lock plate 64 is rotated to the lock gear 32 side at a collision of a vehicle, so that lock teeth 70 of the lock plate 64 are engaged with ratchet teeth 32A of a lock gear 32 and thereby the lock plate 64 is regulated in rotation in the pull-out direction of the lock gear 32. When the lock teeth 70 are engaged with the ratchet teeth 32A, a contact surface 72A of the lock plate 64 abuts on the receiving surface 22A of a leg plate 12B, so that the receiving surface 22A receives a rotation load in the pull-out direction of the lock gear 32. The receiving surface 22A is provided having a clearance from the contact surface 72A. Therefore, the contact surface 72A can be suppressed or prevented from sliding on the receiving surface 22A when the lock plate 64 is rotated to the lock gear 32 side and thereby the rotation performance of the lock plate 64 can be enhanced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
