ABSTRACT:
A mold for manufacturing a steering shaft formed with inner and outer shafts which are telescopically contractible on impact is disclosed. The mold includes an outer shaft supporting mold portion and an inner shaft supporting mold portion that respectively receive the outer and inner shafts in a telescoped position. A first molten resin injection guide portion formed in the outer shaft supporting mold is located in alignment with a hole formed in the outer shaft and a circumferential groove formed in the inner shaft to enable injection of resin through the hole into the groove. A second molten resin injection guide portion communicates with a first opening formed between the outer and inner shafts to enable injection of resin material into this opening to fix the shafts in concentric alignment with each other.
