Abstract
A device for rotatably attaching rollers to a carriage in such a maner that the peripheries of the rollers are maintained in engagement with rail surfaces arranged longitudinally of a rail along which the carriage is adapted to move in sliding movement. The device comprises presser means provided in the carriage and comprising members each associated with one of the rollers, each member being formed therein with a inclined surface and adapted to move in linear motion. At least one of the rollers is supported for movement toward and away from the associated rail surface at right angles thereto. The device further comprises resilient means adapted to resiliently urge the pressing means to bring the inclined surfaces of the presser means into resilient engagement with roller support means whereby the rollers can be maintained in resilient engagement with the respective rail surfaces.
