PROBLEM TO BE SOLVED: To achieve automation of an extrusion operation by a gas drive without an increase in size to facilitate an extrusion operation to improve operability.SOLUTION: A noodle making toole includes: a cylindrical body 1 for storing noodle dough W therein a nozzle body 10 detachably provided on one end of the cylindrical body 1 and having many small holes 14 for molding noodle strings Wa formed therein and an extrusion body 20 for extruding the noodle dough W stored in the cylindrical body 1. A covering part 2 is provided on the other end of the cylindrical body 1, a rod 22 passing through a through hole of the covering part 2 is provided in the extrusion body 20, and a seal part 30 for sealing an interval between the through hole and the rod 22. An interval between the covering part 2 and the extrusion body 20 is configured as a gas chamber 40 to which a gas is supplied, and there is provided a switching valve 42 capable of switching between a feeding mode capable of feeding a compressed gas from an entry door of the gas chamber 40 to the gas chamber 40 and an exhaust gas mode capable of exhausting a gas from the gas chamber 40.COPYRIGHT: (C)2015,JPO&INPIT【課題】 大型化することなく、ガス駆動により押出操作を自動化して押出操作を容易にし、操作性の向上を図る。【解決手段】 麺生地Wが入れられる筒状体1と、筒状体1の一端に着脱可能に設けられ麺線Waを成形する多数の小孔14が形成されたノズル体10と、筒状体1内に入れられた麺生地Wを押し出す押出体20とを備え、筒状体1の他端に覆い部2を設け、押出体20に覆い部2の貫通孔を貫通するロッド22を設け、貫通孔とロッド22との間をシールするシール部30を設け、覆い部2と押出体20との間をガスが供給されるガス室40として構成し、ガス室40の出入口から加圧されたガスをガス室40に給気可能にする給気モード及びガス室40からのガスを排気可能にする排気モードに切換え可能な切換えバルブ42を設けた。【選択図】 図1
