Abstract
The present invention discloses a cover mounting structure for a webbing retractor. This structure relates to a mounting structure of a cover mount and a cover which hold a power spring used for taking up a webbing. By inserting a claw of the cover into an engagement hole portion of the cover mount, a claw on a folded member in which the engagement hole portion is formed enters into a hole portion of the engagement portion, so that the engagement portion is anchored by the claw. That is, the cover can easily be fixed onto the cover mount. Moreover, the engagement portion has elasticity and is constantly urged in the direction of withdrawal by the restoring force, so that the cover does not generate strange sounds.
