Abstract:
1. A motor driven brake apparatus for braking a wheel mounted on a knuckle having an axial portion for rotatably supporting said wheel, and a body portion integrally formed with said axial portion and mounted on a vehicle body, with an opening portion formed on said body portion to be opened toward said vehicle body, comprising: a brake member rotated integrally with said wheel; a friction member mounted on said knuckle to be capable of being in contact with said brake member; an electric motor for driving said friction member toward said brake member to be in contact therewith, said electric motor pressing said friction member onto said brake member to restrain said wheel from rotating; a motion converter accommodated in the opening portion of said knuckle for converting rotating force of said electric motor into pressing force applied by said friction member onto said brake member, said electric motor being mounted on said knuckle, and said motion converter being connected to said electric motor at a side of said knuckle facing said vehicle body; and a circuit board disposed between said motion converter and said electric motor, said electric motor being electrically connected directly to said circuit board.
