A device for manufacturing a motor is disclosed. The motors to be manufactured have a stator body including a stator of the motor, field cores that protrude from the inside surface of the stator body, pole pieces that extend from the field cores to cross with the field cores, coil receiving parts defined by a space facing the field cores, the pole pieces and the inside surface of the stator body, and coils retained in the coil receiving parts. The device has first jigs that extend in the longitudinal direction of the stator body and retain the pole pieces as well as a second jig that extends in the longitudinal direction of the stator body. The second jig has a pressing part corresponding to the arcuate shape of the pole pieces. The device further includes a pressing mechanism that presses the first jigs retaining the pole pieces away from the coil receiving parts, thereby bending the pole pieces away from the coil receiving parts.
