发明名称 WEBBING WINDING DEVICE
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a webbing winding device with improved initial restraining performance capable of preventing or inhibiting the sliding of a clutch transmitting the rotational force of a rotating member to a winding shaft. <P>SOLUTION: In the webbing winding device 10, a pinion 34 of a pretensioner mechanism 30 and a sleeve 22 integrated with a spool 14 are separate from each other in the axial direction, and a webbing 16 can be freely wound and drawn out by the rotation of the spool 14. When the pretensioner mechanism 30 is operated while a vehicle is suddenly decelerated, part of the rotational force of the pinion 34 is converted to a moving force in the axial direction by the engagement of a tapered part 38A and an engagement hole 48, and a gear 36 integrated with the pinion 34 and a key groove 52 formed in the sleeve 22 are directly engaged with each other. Accordingly, no sliding occurs between the pinion 34 and the spool 14 during the initial operation of the pretensioner mechanism 30, so that the initial restraining performance is improved. <P>COPYRIGHT: (C)2003,JPO</p>
