PROBLEM TO BE SOLVED: To absorb rotational variations of a switching cam, while enhancing accuracy of the timing for switching from an ELR (or ALR) to an ALR (or ELR).SOLUTION: In a webbing take-up device 10, an extension rib 94 is extended from a pressing part 88 to the winding direction of an ALR cam 82, and is formed so as to be abuttable with an ALR pawl 104. Thereby, when the ALR cam 82 temporarily rotates too much in the extraction direction to a setting position in the maximum extracted state, an ALR pawl 104 is brought into abutment with the extension rib 94, so that the ALR pawl 104 can be suppressed to be engaged with a V gear 48 across the pressing part 88. Namely, even if a reduction ratio of a speed reduction mechanism 68 is set small and rotational variations of the ALR cam 82 temporarily becomes large, the variations can be absorbed by the extension rib 94. Accordingly, the rotational variations of the ALR cam 82 can be absorbed, while enhancing the accuracy of the timing for switching from the ELR (or ALR) to the ALR (or ELR). |
