Abstract
An electric brake device comprises a caliper holding braking members and having an electric motor attached thereto, a reduction mechanism for transmitting an input rotation of one input element thereof from the electric motor to two output elements thereof at reduced speeds, a rotation-linear motion converting mechanism for converting the rotation of one of the output elements into a linear motion of one of the braking members, and a thrust force support member connected to the other output element and screw-engaged with the caliper, wherein the rotation-linear motion converting mechanism is supported by the thrust force support member to be movable together in a thrust direction and is provided with rotation limiting portions for limiting the rotation in a reverse direction of the one output element to a predetermined range, and wherein the thrust force support member is set to be greater in resistance to operation than the rotation-linear motion converting mechanism.
