A webbing take-up device is obtained capable of suppressing generating of extraordinary noise caused by vibration accompanying vehicle travelling. A switching mechanism of a webbing take-up device is equipped with a lock ring and a body that is formed with a recessed portion that houses the lock ring. The switching mechanism is also equipped with a sheet that is attached to the body so as to cover the recessed portion housing the lock ring. Protruding portions are formed at the sheet. The protruding portions make contact with the lock ring housed in the recessed portion of the body. As a result the lock ring is restricted from vibrating inside the recessed portion.
