<P>PROBLEM TO BE SOLVED: To provide a rolling guide device capable of further reducing sliding resistance by heightening flowability of lubricant in a rolling body returning channel. <P>SOLUTION: A plurality of rolling body supporting parts capable of touching a cross-section contour part of the rolling bodies passing through the rotating axes of the rolling bodies and perpendicular to a moving direction of the rolling bodies, spaced apart a predetermined distance in a peripheral direction of the cross-section contour part partially at a plurality of positions, are arranged in the inner periphery of the rolling body return channel, a lubricant flowing gap capable of flowing the lubricant over a whole length of the rolling body return channel with the cross-section contour part of the rolling bodies are formed among the plurality of the rolling body supporting parts, further in at least one of coupling member guide parts, only either one of side surfaces of a side surface of the side in the inner peripheral side and a side surface of a side in the outer peripheral side in the circulation channel of the rolling bodies when changing a direction is a guide surface for guiding protruding parts of the rolling body holding members, the other side surface faces the lubricant flowing gap. <P>COPYRIGHT: (C)2013,JPO&INPIT |
