PURPOSE:To prevent the leaking of resin outside by disposing a rubber O-ring in between a load side flange and a mold metal mold. CONSTITUTION:A stator 1 consisting of a core mounted with a coil and a load side flange 9 are set to the center core 10 of the lower mold 2 and a rubber O-ring 11 is disposed on the outer circumference of the flange 9, while silicon rubber 12 is placed on the upper surface of the flange 9, then the mold clamping of the upper mold 3 is completed and resin is injected into a cavity. Accordingly, the resin injected into the cavity is prevented from leaking outside travelling along the outer circumference of the bracket 9. |
