<P>PROBLEM TO BE SOLVED: To provide a webbing winding device in which a shaft of a spool side can be easily fitted into an adapter of a spring side. <P>SOLUTION: When attempt is made to insert a fitting-shaft 98 into a fitting-hole 120 while phases of the fitting-shaft 98 of a spring-screw 92 and the fitting-hole 120 of an adapter 116 about a central-axis line of a spool-body are not matched, shaft-side slopes 104 formed at shaft-side protrusions 102 abut to hole-side slopes formed at hole-side protrusions 124, so the shaft-side slopes 104 press the hole-side slopes in such a direction inclined in a pull-out direction to a projecting-direction of a shaft body 100 from a flange 96. The adapter 116 having received a pressing force at the hole-side slopes 126 has rotated in the pull-out direction, and then the phases of the fitting-hole 120 and the fitting-shaft 98 have aligned about the central-axis line of the spool-body 18, each shaft-side protrusion 102 intrudes into a gap between the hole-side protrusions 124 adjacent to each other, and the flange 96 fits into the fitting-hole 120. <P>COPYRIGHT: (C)2012,JPO&INPIT |
