Abrégé
A method of molding a resin casing covering a stator of a motor may include preparing first and second molds; disposing the stator in the first mold; combining the molds; pouring a resin into the cavity; curing the resin; separating the molds; and taking the stator and resin casing from the mold. The stator may include a core, an insulator, and a coil. The core may include a core back surrounding and teeth that extend inward from the core back. The insulator may include wall portions inside the coil. The wall portions may be provided around the teeth and extend toward one side in an axial direction. One of the molds may include cylindrical surfaces contacting inner end faces of the teeth. The first mold may include wall supporting surfaces contacting or facing the inner surfaces of the wall portions. The wall supporting surfaces may be outside the cylindrical surfaces.

Abrégé
A motor includes a casing which is a resin molded article produced by using a core-back, a plurality of teeth, an insulator, a coil, a metal terminal, and a protection member as inserts. The protection member includes a cover section through which the metal terminal penetrates in the axial direction. The protection member or the insulator includes a post section arranged to axially extend in a portion of a surrounding of the metal terminal. A connection space within which a connection point of the metal terminal and the lead wire is disposed is provided between the cover section and the insulator and at the side of the metal terminal from the post section. The lead wire is arranged to reach the connection space through an opening arranged in the post section.
