Abstract:
Provided is a transport device in which reliability is increased by suppressing deterioration of the transport surface and transport efficiency is increased by suppressing electrical current loss. A transport device 1 comprising a transported body having either a permanent magnet 10 or a magnetic body, and an electromagnet unit in which coils 21 are wound around teeth 25 comprising magnetic bodies, and having recesses on surfaces of the teeth 25 facing the transported body. Specifically, the surfaces of the teeth 25 facing the transported body have at least two surfaces (first facing surface 22, second facing surface 23, etc.) which have different distances to the transported body.
