<P>PROBLEM TO BE SOLVED: To provide an electric parking brake device capable of being miniaturized and improved in response property when applying parking brakes. <P>SOLUTION: This electric parking brake device is constituted in such a way that it is provided with an electric motor 1, a conversion mechanism 2, and cables 3, 4 which are pulled by rotating the electric motor 1 forward to apply the parking brakes 5, 6, and the cables 3, 4 are returned by driving and rotating the electric motor 1 reversely to release the parking brakes 5, 6. A clutch mechanism 12 for transmitting the rotation of the electric motor 1 to the conversion mechanism 2 and preventing the transmission of rotation from the conversion mechanism 2 to the electric motor 1 is provided between the electric motor 1 and the conversion mechanism 2. Auxiliary force providing means 30, 31 and 32 for using the direction for pulling the cables 3, 4 as the direction for providing auxiliary forces are provided between the cables 3, 4 and the clutch mechanism 12. <P>COPYRIGHT: (C)2008,JPO&INPIT |
