ABSTRACT:
An emergency locking type retractor has a retractor base, a take-up reel rotatably supported by the retractor base, locking means provided in the retractor base, a latch member, a guide member, a biasing member for urging the latch member towards axially outward direction, a ratchet wheel, a first ratchet movably mounted on the ratchet wheel, an inertia member, a latch portion for engagement with the first ratchet, and a vehicle sensing mechanism having a second ratchet. The retractor is designed such that when rotation of the ratchet wheel is stopped by the first ratchet or the second ratchet, the latch member is caused to slide axially by a cam portion of the ratchet wheel and is led by the guide member to a position in which it is engaged with the locking means, whereby the rotation of the take-up reel in webbing draw-out direction is locked.
