To provide an automatic insertion apparatus of a bone material which efficiently perform only sewing operation to a garment by being connected to an introduction holder for deforming a tape material and introducing it onto a fabric surface of the garment so as to automatically insert the bone material in order.

In the automatic insertion apparatus 11 of the bone material, the introduction holder 4 having a bone material guiding tube and a tape material deforming tube is provided at a sewing machine body 2. The tape material 10 fed continuously is deformed to have an inverse U-shaped cross section in its transporting process through the tape material deforming tube of this introduction holder 4. This deformed tape material is made to be cylindrical by sewing both of the edges of the inverse U-shape to a fabric surface. The bone material in the bone material guiding tube of the holder 4 is automatically inserted in order into the cylinder of this tape material 10.
