PURPOSE: A locking cylinder mounting groove formation device of a door is provided to improve effectiveness and productivity of a work by maintaining a form location of a locking cylinder mounting groove and a plunger retention groove. CONSTITUTION: A locking cylinder mounting groove formation device of a door comprises a contact plate, guide blocks(26), an operating piece(30), a first space adjusting screw(32), a stopper(34), a fixing screw(36), a projecting projection(38), a second space adjusting screw(40), and a fixing piece(42). A cutout groove and a through hole are formed on the contact plate. The cutout groove has a same form with a plunger retention groove formed in a door frame(12). The through hole has a same form with a locking cylinder mounting groove formed in a door. The guide blocks are faced each other between the cutout groove and the through hole of the contact plate. The operating piece fitted to a guide groove(26a) is moved from side to side. The first space adjusting screw fitted to a position fixing hole of the operating piece is moved in a straight line. The stopper allows the contact plate to be not moved. The fixing screw fixes the operation piece. The projecting projection is protruded from the through hole of the contact plate. The second space adjusting screw is coupled with inside of the projecting projection. The fixing piece is fixed on the one side surface of the door in which the through hole of the contact plate is placed. |
