An extension rib extends from a pressing portion in the take-up direction of an ALR cam and is formed to be able to abut with an ALR pawl. Accordingly, when the ALR cam excessively rotates in the pull-out direction with respect to a set position in a maximal pulled-out state, the ALR pawl abuts the extension rib. Accordingly, it is possible to suppress a state in which the ALR pawl climbs over the pressing portion and engages with a V-gear. Namely, even if a rotation variation of the ALR cam becomes large by setting a speed reduction ratio of speed reduction mechanism to a small value, it is possible to absorb such variation by the extension rib. Thus, it is possible to absorb rotation variation of the ALR cam while improving accuracy of switching timing from the ELR(or ALR) state to the ALR(or ELR) state.
