PROBLEM TO BE SOLVED: To provide a door lock device capable of doubly locking a door, easy in installation, and improving usability. SOLUTION: This door lock device has an electronic lock body 60 comprising a lock bolt 69, a lock bolt driving part 67 and a control part 68 including a radio receiving circuit, and a bracket 75 installing the electronic lock body in a door guard. The bracket is composed of an installation plate, an upper pedestal and a lower pedestal fixed to a back face of the installation plate, an auxiliary plate for connecting the mutual pedestals, a knobbed fixing bolt inserted into a screw hole of the upper pedestal, and a pressing body arranged on the lower end of the knobbed fixing bolt. The bracket is fixed to the door guard, by pushing down the pressing body by rotating the knobbed fixing bolt, by inserting the bracket so that an engaging arm 91 of the door guard or an engaging projection for an opening-in door enters between the installation plate and the auxiliary plate and between the pressing body and the lower pedestal.
