A connection structure includes a first apparatus and a second apparatus. The first apparatus includes a first contact portion and a surrounding wall surface. The second apparatus includes a second contact portion and a hollow projection. The first apparatus and the second apparatus are connected as being rotatable relatively to each other around a magnetic force direction and attachable to and detachable from each other, as a result of attraction by magnetic force. The projection is located with a clearance being interposed between the wall surface and the first contact portion, where the projection can be tilted in accordance with pulling including a direction component perpendicular to the magnetic force direction. In the first apparatus, a clearance between a top portion and the projection in a first direction is larger than a clearance between the top portion and the projection in a second direction different from the first direction.
