ド。[Scope of Claim for Utility Model Registration] (1) A nipple holder having a hollow shape and having a tapered nipple at the tip is supported on the die block, and a conductor is inserted through the nipple holder and the inside of the nipple to connect an electric wire cable. In an extruder crosshead that performs extrusion coating processing, a packing made of an elastic material is attached to the end of the nipple holder opposite to the side where the nipple is arranged to form a vacuum chamber within the nipple holder, and to An extruder crosshead characterized in that a vacuum auxiliary chamber is formed adjacent to the chamber. (2) The vacuum auxiliary chamber is formed by fixing one end surface of a roughly cylindrical diaphragm made of an elastic material to the end surface of the vacuum chamber, and attaching a packing made of an elastic material to the other end surface. An extruder crosshead according to claim 1 of the utility model registration claim.
