<P>PROBLEM TO BE SOLVED: To provide an extrusion head structure which can disperse stress generated by flow resistance when molten material with high viscosity is extruded. <P>SOLUTION: A holding member 30 and a spacer member 15 are fitted to a shaft body 21 of a shaft member 20. One end of the shaft member 20 is mounted with a nipple 40. The other end includes a stepped part 24 with its outer diameter larger than an inner diameter of a fitting hole 31 of the holding member 30. The holding member 30 is sandwiched between the nipple 40 and the stepped part 24 through the spacer member 15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
