<p>The present invention aims at providing a drawing apparatus capable of taking out a material, the inner surface of which has been formed into a concavo- convex shape with drawing, from a mold with excellent release performance, even in the case where the concavo-convex part formed in the inner surface of the product is of a shape causing it to get caught in the direction of pulling out of the product against the mold and, in a drawing apparatus comprising a mold 10 disposed at the tip of a spindle 2 and a squeezing roller R for forming a material W into a shape along the surface shape of the mold 10, the mold 10 is realized in a split structure having a concavo-convex surface shape and contractible in diameter after the forming of the material W.</p> |
