PROBLEM TO BE SOLVED: To provide motor assembly parts capable of preventing dust from invading while ensuring a good radiating effect. SOLUTION: The motor assembly parts include a rotating shaft 11 rotatably mounted in a casing, a magnet attachment part 13 surrounding the rotating shaft 11 and rotatable together therewith, a magnet 12 disposed on the magnet attachment part 13, an excitable core having a plurality of stator magnetic poles 32 distant from a rotor magnetic pole of the magnet 12, and a plurality of stator windings 33 wound around the stator pole 32, respectively. The stator winding 33 is distant from end walls 23, 24 of the casing by intervals 34, 35 in the axial direction. To allow the heat emitted from the stator winding 33 to be transferred to the end walls 23, 24 and discharged from the casing, a heat transfer bonding member 4 is disposed astride the intervals 34, 35 in the axial direction.
