To provide a rolling guide device capable of smoothly lubricating a rolling element in a load rolling passage by efficiently taking up a lubricant from a direction changing passage.
This guide device is furnished with a track rail, a large number of balls 3, a connecting body 11 provided with spacer parts 11a to hold the balls 3 with specified intervals between belt parts 11b, 11b and a moving body installed free to move on the track rail through the balls installed on the connecting body 11. In this case, a belt guide groove in a direction changing passage 9 is formed so that the belt part 11b passes at a position slipped to the inner peripheral side of a moving locus L1 of a rolling center C1 of the balls 3. A clearance S is provided between each of the balls 3 passing the direction changing passage 9 and an end part of the outer peripheral side of the spacer part 11a.
