Abstract

PURPOSE: To accurately position a magnet of a coreless motor when molding the housing and the magnet by making a molding pin for forming the lower opening for a screw for mounting the motor contact with the end surface of the magnet by extending the pin.
CONSTITUTION: When molding integrally the housing 1 and a magnet 2 with molding material 3 using molds 17, 16, a molding pin A protruded at the mold 17 for forming the lower opening B for a screw for mounting a coreless motor is extended to make contact with the end surface of the magnet 2 at the end of the pin A. Thus, since both the end surfaces of the magnet 2 in axial direction is controlled by the mold 16 and the pin A, the magnet 2 can be accurately positioned at molding work time.
