An emergency locking retractor with a non-locking mechanism is provided. The mechanism includes a lock means and first, main and auxiliary control means. The lock means is movable between an operated position, where it prevents rotation of a take-up spindle, and a non-operated position where it permits free rotation of the spindle. The first control means detects acceleration and brings the lock means to the operated position. The main control means can take either a holding state, where it holds the lock means at the non-operated position, while the lock means is not required to operate or a non-holding state where it allows the lock means to operate. The main control means is normally biased in the holding state. The auxiliary control means is movable between a first position, where it holds the main control means in the non-holding state, and a second position where it allows the main control means to be brought into the holding state. The auxiliary control means is normally biased to assume the first position.
