PURPOSE: A disk brake device is provided to perfectly prevent a door from being opened even if vibration is given to the door by wind pressure or a shock generated while traveling in a state that the door is closed. CONSTITUTION: When a door is closed, a shaft(14) of an electromotor rotates in the opposite direction of a clock if power is supplied to the electromotor by manipulating a switch toward a closed side, and then at the same time, the closing action of the door starts while a second arm is spread like a first arm as a rotational force is sequentially transmitted to a coupling(31), a worm(13), a worm wheel(12) and a drive shaft(3) so that the first arm(4) is pushed. Herein, when the door reaches just to the completion of closing, the power supply is blocked by a sensing switch but the door is contacted with a door frame of a vehicle body since it is continuously operated by rotational inertia. In addition, the state that the door is closed is kept as the worm obtains a friction resistance force generated by the contact of the rotational disk(24) since a pin(23) keeps the state of connecting with the rotational disk(24) in the coupler, and the pin(28) keeps the state of connecting the coupler with the shaft of the electromotor.
