A friction brake device 10 having: first and second pressing members which press frictional engagement members 14A, 16A against a pair of friction surfaces 20S, 22S, respectively, that are rotatable around a rotation axis 18 as mutually opposed; a force transmission mechanism 46 which transmits rotational torque between the pressing members, transforms the rotational torque into the force separating the pressing members from each other along the rotation axis through a wedge action, and transmits reaction force of the pressing force between the pressing members; a pressing force control mechanism 34 which control the force with which at least one of the pressing members presses the associated frictional engagement member against the associated friction surface; and a rotational torque bearing member 28 which bears the rotational torque transmitted from one of the pressing members to the other of the pressing members by way of the other pressing member. |
