Abstract
A webbing take-up device is provided with a spool that takes up a webbing, a lock base, and a cover plate that covers an outer periphery of the lock base. A tooth portion is formed at the outer periphery of the lock base. The lock base rotates the spool when a rack contacts the tooth portion. The webbing take-up device is further provided with a guide provided at the cover plate. The guide supports the lock base to be rotatable. Thus, contacting together of the ratchet teeth and the lock base is restricted.
