<p>[PROBLEMS] To increase productivity. [MEANS FOR SOLVING THE PROBLEMS] This device is used for manufacturing a spiral spacer having a high tension wire disposed at its center and a spacer body part coated on the outer periphery of the high tension wire and having a plurality of spiral grooves formed in its outer periphery. A twisting device (10) for holding the high tension wire (A) and imparting twist to the wire is provided in just front of a non-rotating die (12) for extruding a molten resin for molding the spacer body part to the outer periphery of the high tension wire (A). The twisting device (10) comprises a holding mechanism part (100) for holding the high tension wire (A) and a twisting mechanism part (101) for the holding mechanism part (100). The holding mechanism part (100) has a plurality of steel rollers formed in pairs which are disposed oppositely to each other around the high tension wire (A) as a center, and hold the high tension wire (A). The paired sets of steel rollers are disposed along the direction of extension of the high tension wire (A).</p>
