A coupling structure of the first and second fan units includes a first structure, and a second structure provided to the second housing. At least part of the first structure protrudes from the first housing in the rotation axis direction. The first structure can fit into the second structure when the first and second fan units come closer to each other to rotate about the rotation axis. At least part of the coupling structure is embedded in the shell portion.
