<P>PROBLEM TO BE SOLVED: To provide a vehicular parking brake device capable of smoothly distributing tensile force to an inner wire connected to both parking brakes and preventing operational sound from becoming higher because of aging. <P>SOLUTION: Preparing sun gears 21, 21C, annular internal gears 23, 23B, 23C, carriers 25, 25C, and planet gear mechanisms 20, 20C composed of planet gears 22, 22C eccentric to the carrier and supported to freely rotate, turning force is given to the sun gears by electric motors 15, 15C for generating turning force in the annular internal gears and the carriers. The turning force generated in the carriers is converted to the tensile force of first brake wires 41, 41B, 41C by first conversion mechanisms 30, 30B, 30C. The turning force generated in the annular internal gears is converted to the tensile force of second brake wires 46, 46B, 46C by second conversion mechanisms 35, 35B, 35C. <P>COPYRIGHT: (C)2009,JPO&INPIT |
