    • A spacer for a linear motion apparatus is to be interposed alternately between balls arranged in an endless circulation passage of the linear motion apparatus. The spacer has a body portion comprising spherical retaining surface portions formed for supporting the balls on both end portions thereof in an advancing direction of the spacer when moving in the endless circulation passage and a circumferential surface portion constituting an outer peripheral portion of the spherical retaining surface portions. The spherical retaining surface portion has a radius of curvature smaller than a diameter of the ball and the circumferential surface portion is provided with a groove extending in the circumferential direction thereof so that one of the spherical retaining surface portions is elastically deformable towards another one thereof. The spacer is preferably applicable to various kinds of linear motion apparatus. Further, rollers as rolling members may be utilized in place of the balls.
    • 用于直线运动装置的间隔件应交替布置在线性运动装置的环形循环通道中的球之间。 间隔件具有主体部分,该主体部分包括球形保持表面部分,该保持表面部分形成用于当在环形循环通道中移动时在间隔件的前进方向上支撑其两端部的球体以及构成球形保持表面的外周部分的周面部分 部分。 所述球形保持面部的曲率半径小于所述球的直径,所述圆周面部设置有沿其周向延伸的槽,使得所述球形保持面部中的一个朝向其另一个弹性变形。 间隔件优选适用于各种直线运动装置。 此外,可以使用作为滚动构件的辊代替球。

    • A linear motion guiding apparatus comprises a guide rail provided with a ball running groove, and a movable block movably arranged along the guide rail through balls. The movable block is provided with a ball running counter-groove, a ball returning passage arranged away from the ball running counter-groove and direction changing passages for connecting these members. A resin-formed body for forming a ball circulation passage comprises a pair of ball passage forming portions, a returning passage forming portion and a pair of direction changing passage-inner guide forming portions. The resin-formed body is separately formed from a body of the movable block. At least two portions of (a) the ball passage forming portions, (b) the returning passage forming portion, (c) one of the direction changing passage-inner guide forming portions and (d) another of the of direction changing passage-inner guide forming portions are connected with each other through integral forming so that the resin-formed body can be built in the body of the movable block.
