    摘要: The present invention provides a motion guide device having an improved scoop section structure which barely induces damage thereto when a moving member is moved at high speed. Balls (13) rolling in ball rolling grooves (11a) of a raceway rail (11) are scooped by a scoop section (22) of a moving block (12) for introduction into non-load ball return paths (17, 21). The scoop section (22) is formed into a shape of a Gothic arch groove for two-point contact with a ball (13) and in a cross-section perpendicular to a traveling direction of the ball (13), an angle (contact angle α) made between a line (L1) connecting a point (P) where the scoop section (22) contacts the ball (13) to a center (C) of the ball (13) and a line (L2) connecting the center (C) of the ball (13) to a bottom (22a) of the scoop section (22) of the Gothic arch groove is more than 30° and equal to or less than an angle (γ) made between a line (L3) connecting the center (C) of the ball (13) that rolls in the ball rolling grooves (11a) of the raceway member (11) to an edge (35) of the ball rolling groove (11a) in the raceway rail (11) and the line (L2) connecting the center (C) of the ball (13) to a bottom of the ball rolling groove (11a) in the raceway member (11).

    摘要: An endless sliding guide apparatus including a track rail, a sliding table having an endless track comprising a load rolling path, a no-load rolling path and a change direction path and rolling bodies wherein at least one of the no-load rolling path, the inner peripheral portion of the change direction path and a rolling body retaining section of the load rolling path is formed by synthetic resin rolling body guide members formed by insert molding using a bearing race as a core. The rolling body guide members are molded by a synthetic resin composition satisfying the relational expression of (a × b) ÷ c ≧ 700 Mpa with respect to the tensile strength a (MPa), tensile elongation b (%) and shrinkage c (%). The endless sliding guide apparatus of the present invention has the advantages that since the endless track of the sliding table is accurately formed, the rolling of the rolling bodies along the endless track is quite smooth, the noise level is minimized and not only the manufacture of the sliding table can be automated but also the problem of "corner cracks" in the synthetic resin rolling body guide members can be eliminated thereby extending the working life of the apparatus.
