Door lock device

A door lock device comprising:

• a latch mechanism for being selectively engaged with a striker;
• an open unit operating at a plane surface of a housing of the door lock device perpendicular to one direction for transmitting an opening operational force from a vehicle inside and from a vehicle outside to operate the latch mechanism from an engaged state with the striker to the disengaged state from the striker;
• a lock unit operating at a plane surface perpendicular to said one direction for transmitting an operational force to the open unit for operating the open unit to be an unlocked state for transmitting the opening operational force to the latch mechanism and a locked state not for transmitting the opening operational force to the latch mechanism;
• said one direction being a direction of thickness of a door of a vehicle;
• and
• the open unit including a first lever rotatable about a first rotational axis by the operational force from the vehicle outside, the first rotational axis being arranged approximately in parallel with the direction of thickness of the door.
