In a linear motion guide unit in which separators are arranged between any adjacent rolling elements, or balls, running through recirculating passages, the separators are each formed for elastic deformation to well compensate the recirculating passages for variance in length. Each separator is comprised of a major body and elastic supports positioned at desired intervals around the major body. The elastic supports are each composed of an elastically deformable leg extending radially outwardly of the major body and a seat formed integrally with the deformable leg. When the force rendering the adjacent balls near each other is small, the separator comes into contact with the associated ball at only the outermost end of the seat. In contrast, with the increase of load exerted on the balls to make them near each other, the seat makes displacement to its retreated position by virtue of the elastic deformation of the leg, so that the area where the separator makes contact with its associated ball reaches an annular peripheral area the major body.
