PROBLEM TO BE SOLVED: To make the feature "magnetism generation means usable as support posts" compatible with the feature "improved magnetic efficiency" with one end of a coil bobbin entered into a magnetic pole hole in a case body inner surface and with a flange part of the coil bobbin contacting the case body inner surface.SOLUTION: In a magnetic treatment device including a case body 2 provided with a magnetic action surface 2a, and magnetism generation means 3 built in the case body 2, the magnetism generation means 3 comprises: a coil bobbin 6 with a spool 5 having flanges 4, 4 at both ends and with the spool 5 wound by electric wires around it and an iron core 7 fitted into the spool 5 with one end part 7a projecting from one flange of the coil bobbin 6. The projecting one end part 7a of the iron core 7 is entered into a magnetic pole hole 8 formed in an inner surface of the magnetic action surface 2a, and one flange 4 is brought into contact with the inner surface of the magnetic action surface 2a, thereby regulating a concavity to the inner surface of the magnetic action surface 2a by the magnetism generation means 3. The projecting one end part 7a of the iron core 7 is shaped tapering down, and the magnetic pole hole 8 in the inner surface of the magnetic action surface 2a is shaped widening toward the opening.COPYRIGHT: (C)2014,JPO&INPIT【課題】コイルボビンの鉄心一端をケース体内面の磁極孔に進入させ、コイルボビンの鍔部をケース体内面に当接させて、「磁気発生手段によるケース体の支柱兼用」と「磁気効率の向上」を両立する。【解決手段】磁気作用面2aが設けられたケース体2と、ケース体2に内蔵された磁気発生手段3を有し、磁気発生手段3は、両端に鍔部4、4を設けたスプール部5の周面に電線が巻かれたコイルボビン6と、コイルボビン6の一方の鍔部4から一端部7aが突出した状態でスプール部5内に嵌入される鉄心7を備え、鉄心7の突出した一端部7aをケース体2の磁気作用面2a側の内面に形成された磁極孔8に進入させ、且つ、一方の鍔部4をケース体2の磁気作用面2a側の内面に当接させて、磁気作用面2aの内面側への凹みを、磁気発生手段3で規制し、鉄心7の突出した一端部7aを先細り状に形成し、磁気作用面2a側の内面の磁極孔8を開口末広がり状に形成している。【選択図】図1
