The other one of the shaft assembly members fitted in the slit provided on the joining surface is provided with upper and lower fitting insertion holes that intersect the slit, and a drift pin is joined to each fitting insertion hole. It is set as the structure inserted in contact with the said inclined edge part.

  According to the present invention, when the drift pin is driven into the insertion hole, it contacts and presses the inclined edge formed on the joining plate. It is possible to provide a shaft assembly material joining apparatus that can perform a pulling operation with certainty and that can obtain a stable joining state with a simple structure because it employs a structure in which a pair of joining plates are sandwiched between upper and lower drift pins.
