A friction brake device has a brake rotor including a disk part and a subsidiary rotor spaced apart from each other along a rotation axis and a cylindrical part integrally connecting their outer peripheral portions, brake pads which are rotatably supported around an autorotation axis parallel to the rotation axis between the disk part and the subsidiary rotor by a stationary member, rotational torque transmission devices which mutually transmit rotational torques between the brake rotor and the brake pads, and pressing devices which are supported between the disk part and the subsidiary rotor by the stationary member and press the brake pads against the disk part and the subsidiary rotor. |
