    • A linear guide apparatus includes a guide rail 4 and a slider 10. At least one of grooves provided on the guide rail 4 and the slider 10 is a groove having a V-like cross sectional shape formed by a combination of two curved surfaces having a circular arc cross sectional shape. One of the two curved surfaces is in contact with balls 7 when the apparatus is in use, and the other curved surface is not in contact with the balls 7 when the apparatus is in use. The depth from an end of one curved surface with respect to the circumferential direction to the bottom of the groove is larger than the depth from an end of the other curved surface with respect to the circumferential direction to the bottom of the groove.
    • 线性导向设备包括导轨4和滑块10.设置在导轨4和滑块10上的凹槽中的至少一个是具有V形横截面形状的凹槽,该凹槽由两个曲面的组合形成,该曲面具有 圆弧截面形状。 当装置使用时,两个曲面中的一个与球7接触,而另一个曲面在装置使用时不与球7接触。 从一个曲面的相对于圆周方向的端部到凹槽的底部的深度大于从另一个曲面的相对于圆周方向的一端到凹槽的底部的深度。
