<p><P>PROBLEM TO BE SOLVED: To provide a webbing winding device provided with a lock mechanism and a pre-tensioner mechanism, capable of suppressing the number of parts and being miniaturized. <P>SOLUTION: A sleeve 72 and a sleeve extension part 73 constituting the pre-tensioner mechanism 50 are integrally formed on a shaft core part of a lock gear 70 constituting the lock mechanism 130. Thus, respective constitution elements of the inherently different two mechanisms (lock gear body 74 and rachet tooth 76 of the lock mechanism 130 and sleeve 72 and sleeve extension part 73 of the pre-tensioner mechanism 50) are integrated to make the lock gear 70 multi-functional. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
