使用に好適である。Further, in the twin fan of the present invention, since the rotation axis of the driving fan and the rotation axis of the driven fan are substantially perpendicular to each other, the flow direction of the fluid by the driving fan and the flow direction of the fluid by the driven fan are perpendicular to each other. It is suitable for use in a harsh environment.

るツインファン。1. A driving apparatus comprising: a partition plate made of a non-magnetic non-conductive material; a driving fan mounted on one surface of the partition plate and driven to rotate; and a driven fan mounted on another surface of the partition plate. The fan includes a drive-side rotator having a rotation axis substantially parallel to the partition plate, and the drive-side rotator includes a plurality of drive-side permanent magnets that sequentially approach and separate from the partition plate during rotation. And, the driven fan includes a driven-side rotating body disposed close to the partition plate, the driven-side rotating body has a rotation axis perpendicular to the partition plate, the driven fan, When the driving fan rotates, the driven-side rotator rotates following the rotation of the driving fan by receiving a magnetic attraction force and / or a force acting on an eddy current by the driving-side permanent magnet portion. A twin fan characterized by the following.
