PROBLEM TO BE SOLVED: To provide a wearable chemical-diffusion apparatus evaporating a large quantity of chemicals and diffusing it into the atmosphere, without using a motor or a battery.SOLUTION: The chemical-diffusion apparatus is provided with an apparatus body 1 attachable to the workers body with an attaching tool 3, a chemical-holding means 2 attached to the apparatus body 1 so as to rotate due to the motion of the apparatus body 1, and the first magnet 4 and the second magnet 5 attached to the chemical holding means 2 and the apparatus body 1. The chemical-holding means 2 has a chemical impregnation material 2a dissipating the chemical in contact with air, the rotation of the chemical-holding means 2 is promoted to a plurality of times of reciprocating rotations by the first and second magnets 4, 5, and a large quantity of the chemical is dissipated from the chemical impregnating material 2a and is diffused to the atmosphere.COPYRIGHT: (C)2009,JPO&INPIT【課題】モータ、電池を使用せずに多くの薬剤を揮散して大気に拡散できる着用型薬剤拡散装置とする。【解決手段】着用具3で身体に着用される装置本体1と、この装置本体1に、当該装置本体1の動作により回転するように取付けた薬剤保持手段2と、この薬剤保持手段2と前記装置本体1とに取付けられた第1の磁石4、第2の磁石5を備え、前記薬剤保持手段2は空気と触れると薬剤を揮散する薬剤含浸体2aを有し、この薬剤保持手段2の回転が第1・第2の磁石4,5によって複数回の往復回転に助長され、その薬剤含浸体2aから多くの薬剤を揮散して大気に拡散できるようにする。【選択図】図2
