Patent ID: 7427044

Claim:
A webbing retractor comprising: a metal lock gear having teeth that rotates with at least one of the taking up and pulling out of a webbing; a metal lock plate that blocks rotation of the metal lock gear by engaging and meshing with the teeth of the metal lock gear; a retaining component formed from a deformable plastic material that retains the metal lock plate in a movable state; and a blocking component that blocks deformation of the retaining component due to movement of the metal lock plate towards a retaining component side, wherein the strength of the blocking component is greater than the strength of the retaining component, and wherein the retaining component is elastically deformable and the blocking component blocks bending of the retaining component in a direction substantially perpendicular to the movement direction of the metal lock gear when the teeth of the metal lock plate engage and mesh with the rotating component, and wherein a circular rotating axis is uniformly formed at one end of the lock plate and the rotating axis is inserted into a support hole of the retaining component, whereby the lock plate is supported at the rotating axis so as to be able to rotate in the retaining component.
