WIPO Patent Application WO/2014/042089

A1

A guiding body (2, 20), and a motion-guiding device using the guiding body, it being possible for the guiding body (2, 20) to be prevented from detaching from a raceway rail even if a low-rigidity material is used for the raceway rail, the guiding body (2, 20) being kept moving along the raceway rail in a reliable manner, the guiding body (2, 20) being provided with a plurality of rolling bodies (3, 30) that travel over a traveling surface (11, 120) formed on a structure (1, 1A), and the guiding body (2, 20) having the capability of moving in relative fashion with respect to the structure (1, 1A); wherein the guiding body (2, 20) is characterized in having an endless circuit path (4, 40) over which the rolling bodies (3, 30) circulate and a load opening (5, 260) via which the rolling bodies (3, 30) in the endless circuit path (4, 40) are allowed to contact the traveling surface (11, 120) of the structure (1, 1A), there being formed on at least one side of the load opening (5, 260) a guiding part (6, 280) protruding further toward the structure (1, 1A) than a protruding end of the rolling element (3, 30) protruding towards the structure (1, 1A) through the load opening (5, 260).
