PROBLEM TO BE SOLVED: To provide a door lock unit capable of preventing a person from knowing a thumb-turn position from the outside to increase anti-theft property. SOLUTION: This door lock unit is provided with a dead bolt driving shaft 4 rotated and operated by a cylinder lock 2 arranged on an outdoor side wall face 1a of a door body 1 to move a dead bolt 3 to locking and unlocking positions. This unit has a lock device 7 in which rotary operation to the dead bolt driving shaft 4 from an indoor side is possible by only a cable 6 whose one end is connected with a cable connection plate 5 connected with the dead bolt driving shaft 4 and a thumb-turn device 8 provided with the cable connection plate 5 with which the other end of the cable 6 is connected and which can transmit rotary driving force to the dead bolt driving shaft 4. An indoor side operation part of the lock device 7 is arranged in a non-overlapping region with the lock device 7 when viewed in front. COPYRIGHT: (C)2004,JPO&NCIPI
