PROBLEM TO BE SOLVED: To provide an apparatus and a method for manufacturing a transfer-type crankshaft, with which a main-forming process and a hollow-forming process can be continuously performed. SOLUTION: In a hollow-forming die 126, a liner part for adjusting the position in the height direction of the hollow-forming die 126 and a shim part 132 for adjusting the position of the hollow-forming die 126 in the horizontal direction. The thickness adjustment of a hole part (adjustment in the height direction) needed in the hole-formation with the hollow-forming die 121 can be made by the height adjustment of the hollow-forming die 126 by the linear part. According to the charging position of a pre-formed product P into the hollow-forming die 126, the insertion of the pre-formed product into the cavity of the hollow-forming die 126 can be easily performed by adjusting the position of the hollow-forming die 126 in the horizontal direction by the shim part 132.
