<P>PROBLEM TO BE SOLVED: To facilitate adjustment of pulling sensitivity of webbing by adjusting a center-of-gravity position of a rotation detecting member without changing the shape of an outer periphery of the rotation detecting member. <P>SOLUTION: In this webbing take-up device, when a V gear is rotated in a pulling direction to follow a spool and a W pawl 60 is relatively displaced with respect to the V gear by inertial force, rotation of the V gear is regulated and a lock plate 46 regulates rotation of the spool. The W pawl 60 includes a first center-of-gravity adjusting hole 66 and a second center-of-gravity adjusting hole 68, and a center-of-gravity position is adjusted to adjust sensitivity for detecting the inertial force. The first center-of-gravity adjusting hole 66 and the center-of-gravity adjusting hole 68 are provided to be away from an outer peripheral surface 69 of the W pawl 60, and thereby the center-of-gravity position of the W pawl 60 can be adjusted without changing the shape of the outer periphery of the W pawl 60. <P>COPYRIGHT: (C)2012,JPO&INPIT |
