Abstract

A linear conveyance device includes a conveyance carrier and a stator-side platform. The conveyance carrier includes: a conveyance carrier main structure; a first roller and a second roller; a mover-side magnetic element that drives the conveyance carrier main structure with respect to the stator-side platform; and a mover-side counter moment generating element that generates a counter moment against overturning of the conveyance carrier between the mover-side counter moment generating element and the stator-side platform. The stator-side platform includes: a first rail that engages with the first roller; a second rail that engages with the second roller; a stator-side magnetic element paired with the mover-side magnetic element to generate a magnetic attraction force in a horizontal direction; and a stator-side counter moment generating element that generates the counter moment between the stator-side counter moment generating element and the mover-side counter moment generating element paired therewith.
