To provide a roller conveyer which simplifies a constitution, decreases a noise, attains high speediness, reduces generation of trouble, and facilitates addition of an accumulating function.

A magnetic force generating member 3B generating attraction force or repulsion force to or against external magnetic force is provided, and a cylindrical roller 3 which is made ratable around itself axis orthogonal to a conveying direction of an article 9 to be plurally juxtaposed along the conveying direction of the article 9 to serve as the rotor of a linear motor 2, is provided. In addition, relating to the magnetic force generating member 3B of each cylindrical roller 3, a plurality of drive coils 11, with N/S pole side magnetic flux capable of alternately going out, area provided in a primary side stator member 5 serving as a primary side stator of the linear motor 2.
