<p><P>PROBLEM TO BE SOLVED: To provide a webbing retractor suppressing the relative movement of a rotor with respect to a frame with a rotation prevention member engaged, without highly accurately manufacturing the rotor or a winding shaft. <P>SOLUTION: In the webbing retractor 10, an inclined surface 138B of a pawl 138 is abutted on the inclined surface 136A of an external tooth 136 in a state that the pawl 138 is engaged with a gear 132 for WSIR, so that a force toward one end side in an axial direction acts on the gear 132 for WSIR and the gear 132 for WSIR is abutted on (pushed against) a wall part 68A of a sensor holder 68. Therefore, even if dimension accuracy between a bearing hole 133 of the gear 132 for WSIR and a small-diameter shaft 16C of a spool 16 is small and an outer peripheral part of the gear 132 for WSIR is loose in an axial direction with respect to the spool 16, the relative movement in the axial direction with respect to the frame 12 of the gear 132 for WSIR in the engaged state can be suppressed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
