2 is pressed toward the lower mold side, and the injected molten material flows around the base 12 and flows to the lower surface. At this time, since the supporting portion 45 for maintaining the gap between the lower surface of the base 12 and the cavity is made of small protrusions, it does not hinder the flow of the molten material. Therefore, the entire lower surface of the base 12 can be uniformly filled.

態を維持できる。As is apparent from the above description, the walking guide body of the present invention is provided with a large-diameter portion, which is larger than the inner diameter of the insertion hole of the substrate, below the head of the embedded shaft. Since the diameter portion is fixed to the upper edge of the insertion hole by press fitting, welding work and polishing work accompanying this welding work are unnecessary. Therefore, it can be manufactured at low cost and the connected state can be reliably maintained.
