Each spiral forming die includes a bottom face forming a shape corresponding to a curvature of a spiral on a plane intersecting with an axis at right angles between an inner peripheral face of the housing and the bottom face, a Z-winding wall face forming a shape corresponding to a pitch of the Z-winding spiral inclined with respect to the plane, and an S-winding wall face forming a shape corresponding to a pitch of the S-winding spiral. The S-and Z-winding wall faces intersect each other at a central portion of the spiral forming die.
