SOLUTION: The arm body 6 is overturnably provided to the indoor surface 1d of the door body 1, and is engaged with an engagement body 8 arranged on the right-hand door frame body 5 in a fully-closed position of the door body 1. When the arm body 6 is brought into a state that it is raised upright on the indoor surface 1d, the tip of the U-shaped part 6a of the arm body 6 and the engagement body 8 are engaged with each other to prevent from coming out depending on the opening of the door body 1. Thus, the opening of the door body 1 can be regulated, and a crime-prevention device 9 is provided to the engagement part between the U-shaped part 6a of the arm body 6 and the engagement body 8. The crime-prevention device 9 causes a buzzer device 11 to sound a horn as the engagement force between the U-shaped part 6a of the arm body 6 and the engagement body 8 reaches a predetermined level.
