Abstract
A disk brake device has a rotor having a braking surface, a caliper, an outer pad and an inner pad each disposed to face the braking surface, and a braking operation mechanism which performs an operation of pressing the two pads against the braking surface. The braking operation mechanism includes a base plate, a wedge plate which holds the inner pad, a first movement conversion mechanism which moves the wedge plate in a direction perpendicular to the braking surface, while moving the wedge plate to slide relative to the base plate in a rotating direction of the rotor in parallel to the braking surface, an electric motor unit which outputs a rotational driving force, and a second movement conversion mechanism which moves, using the rotational driving force of the electric motor unit, the wedge plate to slide in the rotating direction of the rotor in parallel to the braking surface.
