摘要： In a ball screw device comprising a screw shaft and a nut which make relative movement to each other through a multiplicity of balls, as well as in a linear motion device comprising an outer member and an inner member which make the relative movements to each other through the multiplicity of balls, a spacer having two concave surfaces facing respectively to balls, is disposed between the balls adjacent to each other. A section of each of the concave surfaces of the spacer is formed of two circular arcs of which central positions deviate from each other to form a Gothic arch. The spacer has such a configuration that the balls adjacent to each other come into contact with outer edges thereof or portions vicinal to the outer edges. The spacer also has such a configuration that the balls adjacent to each other come into contact with at least three or more outer edge portions thereof or portions vicinal to the outer edges. The spacer may have a through-hole formed in a thinnest portion thereof.

摘要： A linear guide device is provided with a plurality of rolling elements. A guide rail extending in an axial direction thereof and including a plurality of rolling element rolling grooves in two side portions thereof is provided in the device, wherein the rolling grooves extend in an axial direction of the guide rail. A slider includes a plurality of rolling element rolling grooves respectively opposed to the rolling element rolling grooves of the guide rail, wherein the slider is supported on the guide rail in such a manner that the slider is movable along the axial direction of the guide rail through the rolling movements of the rolling elements respectively inserted between the rolling element rolling grooves of the slider. The slider includes a rolling element endless circulation track along which the rolling elements are allowed to circulate endlessly; and a plurality of separators, each interposed between the adjoining rolling elements in the circulation direction of the rolling elements. A clearance is formed between a line of the rolling elements and the separators which are endlessly circulated.

摘要： An attaching device for a bellows type dust cover of a linear guide apparatus includes a plate-shape main body and a bellows attaching plate portion integral with the plate-shape main body. The plate-shape main body has fitting plate portions which are formed by bending lower edge portions of both lateral side plate portions respectively inwardly at right angles so that both the fitting plate portions horizontally oppose each other. The fitting plate portions are respectively fitted into ball rolling grooves formed in both lateral sides of a guide rail, or into retainer relief grooves formed in groove bottoms of the ball rolling grooves. Thus, the plate-shape main body straddles an upper surface of the guide rail and sandwiches both lateral sides of the guide rail so that it is securely held to the guide rail. The bellows attaching plate portion is provided at one axial end of the plate-shape main body perpendicularly to the upper surface of the plate-shape main body. The bellows attaching plate portion has screw holes. A bellows which covers the guide rail has one end fixed to the bellows attaching plate portion by screws and the other end fixed to a slider.
摘要翻译：线性导向装置的波纹管式防尘罩用安装装置包括板状主体和与板状主体一体的波纹管安装板部。板状主体具有嵌合板部，其通过使两侧板部分的下边缘部分分别以直角向内弯曲而形成，使得两个嵌合板部分水平地彼此相对。装配板部分分别装配在形成在导轨的两个侧面上的滚珠滚动槽中，或者嵌入到形成在滚珠槽的凹槽底部的保持器释放槽中。因此，板状主体跨越导轨的上表面，并将导轨的两侧侧夹住，使其牢固地保持在导轨上。波纹管安装板部分在板状主体的一个轴向端部垂直于板状主体的上表面设置。波纹管安装板部分具有螺纹孔。覆盖导轨的波纹管的一端通过螺钉固定在波纹管安装板部上，另一端固定在滑块上。
