Patent ID: 8876225

Claim:
An electro-mechanical brake unit comprising: an electric motor; a pad generating a friction force on the basis of a rotational drive force of said electric motor, the pad being arranged at a first end of the electric motor; and a control unit arranged at a second end of said electric motor, the first end and the second end being on opposite sides of the electric motor, wherein said control unit has a resin case constructed by a resin, an inverter module retained by said resin case and including a plurality of terminals, a plurality of bus bars, and a metal case covering said resin case and said inverter module, wherein each of said plurality of bus bars is partially exposed to outside of an outer surface of the resin case and has a connection portion for being connected to a terminal of said inverter module, wherein a first surface of the connection portion of said bus bars is embedded in said resin case and a second surface of the connection portion of the bus bars opposite said first surface is exposed to the outside of the outer surface of said resin case, wherein the terminals of said inverter module are arranged so as to overlap the connection portions of said bus bars and are connected to the connection portions of the bus bars, and wherein a level of the outer surface of the resin case located between adjacent bus bars is the same as a level of the outer surface of the resin case located outside of each of the adjacent bus bars, except that the resin case includes a resin projection portion projecting from a part of the outer surface of the resin case located between adjacent bus bars and projecting away from the second surface of each of the plurality of bus bars.
