摘要： A magnet structure includes first and second magnet units. The first magnet unit is provided with a first magnet fixing section that includes a first surface and a first magnet having a first polarity on the first surface's side. The second magnet unit is provided with a second magnet fixing section that includes a second surface and a second magnet having a second polarity on the second surface's side, the second polarity being an opposite polarity to the first polarity. The first and second surfaces are located next to one another on the same plane to form a magnetic attachment surface which is magnetically attached to a magnetically-attached object. The second magnet unit is supported by the first magnet unit so as to move in a predetermined range.
