DOOR LOCK DEVICE

PROBLEM TO BE SOLVED: To provide a door lock device which enables quiet locking. SOLUTION: A ratchet for forbidding the turning of a hook 133 in an unlocking direction is composed of a half-lock ratchet 301 and a full-lock ratchet 303; the hook 133 is provided with a protrusive half-lock locking part 143 which is elongated in the direction of the rotating shaft of the hook 133 and with which the ratchet 301 is to be engaged, and also provided with a half lock ratchet stopper 108 which is composed of an elastic body for forbidding the ratchet 301 on a moving locus of the locking part 143 to be further turned in a hooking direction; and a sound, which is generated by having the rachet 301 hit the hook 133 during the passage of a half lock, is eliminated.
