摘要： A new shape of an unloaded roller return path where rollers can be smoothly moved. A roller circulation path of a roller screw is constructed from a loaded roller rolling path and the unloaded roller return path. The unloaded roller return path (10) is twisted so that the center axes of the rollers (4) tilt when they moves in the unloaded roller return path (10). In a cross-sectional shape of the twisted portion of the unloaded roller return path (10), a pair of side face corresponding portions (25c, 25d) facing end faces of the rollers (4) is formed in a shape projecting to the inside of the unloaded roller return path (10)

摘要： A movement guiding device in which there is no possibility that a pickup part is broken even if a movement member is moved at a high speed. When viewed from the axial direction of a track axis (1), a direction changing passage (10) is tilted relative to a contact angle line (L1)(line connecting the bottom (P1) of a ball rolling groove (1a) to the center (C) of a ball (3)). The cross section of the direction changing passage (10) including the pickup part (17) is formed in a Gothic arch groove shape formed of two circular arcs (R1) so as to come into contact with the ball (3) at two points. Then, the direction changing passage (10) is twisted so that the locus (18) of the top of the Gothic arch groove shape nears the contact angle line (L1) at the pickup part (17).

摘要： A suspension is provided which can not only generate a damping force between sprung mass and unsprung mass but also steer a wheel. A suspension (3) includes: a shaft (5) coupled to sprung mass of a vehicle, the shaft (5) having a screw groove (5a) and a spline groove (5b) formed thereon; a ball screw nut (6) assembled to the shaft (5) via a ball (17); a ball spline nut (7) assembled to the shaft (5) via a ball (10); a ball screw-specific motor (8) connected to the ball screw nut (6); a ball spline-specific motor (9) connected to the ball spline nut (7); and a case (18) coupled to unsprung mass of the vehicle, the case (18) being configured to hold the ball screw-specific motor (8) and the ball spline-specific motor (9). The ball spline-specific motor (9) rotates the ball spline nut (7) and the shaft (5) relative to the case (18).

The roller circulation path of the roller screw has the unloaded roller return path and a loaded roller rolling path. The unloaded roller return path 10 is twisted so that while each roller 4 moves in the unloaded roller return path 10 its central axis is inclined. In a cross sectional shape of the twisted part of the unloaded roller return path 10, each of paired side surface corresponding parts 25c and 25d facing respective side surfaces of the roller 4 is convex toward the inside of the unloaded roller return path 10.

摘要： Provided is a motion guide device having a scooping portion that is not damaged even when a moving member is moved at high speed.
When seen in an axial direction of a track shaft 1, a direction change path 10 is inclined relative to a contact angle line L1 (line connecting a center C of a ball 3 and a bottom P1 of a ball rolling groove 1a). The direction change path 10 including a scooping portion 17 has a cross section of Gothic arch groove shape formed of two arcs R1 in such a manner that the ball 3 is in contact with the direction change path 10 at two points. The direction change path 10 is twisted in such a manner that a locus 18 of the top of the Gothic arch groove shape approaches the contact angle line L1 at the scooping portion 17.
