PURPOSE:To easily eliminate the clogging of the title contact body, by incorporating plural coil-spring contact materials capable of being vertically expanded and contracted into a contact body, and vertically expanding and contracting each contact material when the contact body is clogged. CONSTITUTION:A framework 80 obtained by assembling shape materials in the form of a rectangular parallelepiped, plural coil-spring contact materials 84 arranged in the framework 80 and capable of being vertically expanded and contracted, and a covering member 86 surrounding the upper end of each contact material 84 are provided to the contact body for the purifying device. When the contact body is clogged, each contact material 84 can be vertically expanded and contracted. As a result, the film of microbes stuck to the contact material is released, and clogging can be easily eliminated.
