ABSTRACT:
In a webbing retractor used in a seatbelt system for protecting an occupant in an emergency situation of a vehicle, a first guide portion of a cam ring is opposed to a transmitting means to thereby put a locking means in an engageable condition until a webbing is unwound up to a first predetermined amount, an acceleration sensor puts the locking means in an engaged condition to stop a webbing-unwinding rotation of a takeup shaft only in the emergency situation of the vehicle, a second guide portion of the cam ring is opposed to the transmitting means to thereby bias the locking means in the engaged condition when the webbing is unwound in an amount of more than the first predetermined amount, and, thereafter, an automatic locking mechanism is worked when the occupant, a fixture such as a child seat or the like is embraced by the webbing, so that the occupant, the fixture or the like is restrained surely.
