A circulation maintaining device for a linear slide assembly includes two top boards, four half mediate plates, two third half tubes, two bottom boards, and two end caps. Each of the above mentioned parts is manufactured integrally by way of injection molding and needs only one set of molds. These parts are connected to the slider symmetrically. Each of the half mediate tubes provides a second half tube and a half mediate plate. The second half tubes are inserted into the top holes and the bottom holes from two ends of the slider. The two half maintaining plates each have stops and recessed areas in longitudinal direction thereof so as to form restriction in transverse direction. The half maintaining plats each have ribs which are engaged with the grooves in the slider to provide positioning effect in a vertical direction.
