Webbing retractor

摘要

A webbing retractor winds-up a webbing by a winding shaft. A lock ring rotates according to movement of the winding shaft. A rotational delay of the lock ring with respect to the winding shaft is generated when the webbing is rapidly drawn-out. The rotational delay of the lock ring causes a lock plate to prevent the webbing from being drawn-out. An engaging member is movable to a separated position where the engaging member is separated from the lock ring, and to an engaging position where the engaging member engages the lock ring to generate rotational delay. Further, the engaging member is urged in one of the direction of the separated position and the direction of the engaging position when the engaging member is separated from a neutral position disposed at an intermediate portion between the separated position and the engaging position. A moving member moves with the winding shaft and rotates. A guide member in the moving member guides the engaging member to an engaging waiting position positioned on an engaging position side with respect to a neutral position and the engaging member disengages the lock ring by moving the moving member according to movement of the winding shaft to rotate as the webbing is drawn-out. The guide member guides the engaging member to the engaging position by moving the moving member with the winding shaft to rotate as the webbing is retracted in a condition where the engaging member is positioned at the engaging waiting position.
