PROBLEM TO BE SOLVED: To provide a magnetic therapeutic device which has a constant outer diameter, high flexibility and strength, and constant surface magnetic flux density, and can increase magnetic force effectively and partially without increasing the entire magnetic force to consequently prevent the onset of nausea caused by magnetism, and a method for manufacturing the same.SOLUTION: A method for manufacturing a magnetic therapeutic device having a core material which extends in one direction, has a bulging part with an enlarged diameter in the middle, and contains rubber and magnetic powder and an outer layer for covering the core material includes a bulging part molding process for extruding a core material forming rubber composition by moving a movable in-die, provided in a discharging hole of an out-die to be movable forward and backward, backward or forward and for extruding an outer layer forming rubber composition to the outside of the core material forming rubber composition. The magnetic therapeutic device manufactured by the method is disclosed.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2017,JPO&INPIT【課題】外径が一定で柔軟性及び強度が高く、表面磁束密度が一定であり、全体の磁力を高めることなく効果的かつ部分的に磁力を高めることができ、その結果、磁気酔いの発症を防止できる磁気治療具、及び、その製造方法を提供することを課題とする。【解決手段】一方向に延在し、その途中に拡径した膨出部を有し、ゴム及び磁性粉を含有してなる芯材と、該芯材を被覆する外層とを有する磁気治療具を製造する方法であって、アウトダイスの排出孔内に、前後進可能に設けられた可動インダイスを後進又は前進させて芯材形成用ゴム組成物を押し出すと共に、前記芯材形成用ゴム組成物の外側に外層形成用ゴム組成物を押し出す膨出部成形工程を有する磁気治療具の製造方法、及び、この方法により製造された磁気治療具。【選択図】 図9
