WEBBING WINDER

摘要

[PROBLEMS] To obtain a simple and compact webbing winder capable of transmitting rotation from the motor side only to a winding shaft by a clutc h. [MEANS FOR SOLVING PROBLEMS] The clutch of a webbing winder has such a simpl e arrangement that the slider (144) at the clutch body section (114) and a loc k lever (154) are moved relatively by holding the slider (144) on a case with a frictional force, and the lock lever (154) is shifted to a position engaging with a ratchet (134) or a position disengaging therefrom through the relativ e movement. As compared with a conventional clutch where a pawl is moved using a large and heavy inertial disc, overall structure of the clutch (100) can be reduced (can be made thinned) greatly and thereby overall structure of the webbing winder (10) can be made compact.
