Abstract:
A conveying apparatus includes: a housing; a movable member; a linear motor; and a cover. The linear motor includes a primary magnetic pole and a secondary magnetic pole each having a facing surface that faces the other and that is a plane along the longitudinal direction of the housing. The cover allows the primary magnetic pole to be located in an atmospheric environment, and the secondary magnetic pole to be located in a vacuum environment or a reduced pressure environment by separating the primary magnetic pole and the secondary magnetic pole from each other. The primary magnetic pole and the secondary magnetic pole face each other so that a direction of a magnetic attraction force generated therebetween and acting on their facing surfaces is different from directions of forces acting, due to an atmospheric pressure outside the housing, on the wall of the housing on which the cover is provided.
