PROBLEM TO BE SOLVED: To protect an internal mechanism of a lock by preventing components of the lock from directly receiving a great load caused by operation force of an outer side operation member.SOLUTION: A door lock device includes: an operation member for opening and closing a door; a first rotation body 12 provided in a case 11 so as to be driven by an operation force of the operation member; a slider 14 provided in the case so as to linearly move by a drive power of the first rotation body and having a limiter member 51; a second rotation body 22 provided in the case so as to interlock with the slider; and a locking piece provided in a lock box separate from the case so as to move by a rotating force of the second rotation body. The limiter member consists of a movable engaging rod 52 engaging with the second rotation body and an elastic element 53 provided on the movable engaging rod. The elastic element controls so that a load of the slider to the second rotation body is alleviated when the second rotation body is stopped during movement of the slider and moreover when the slider continues to be moved as it is by the operation force of the operation member. |
