<p><P>PROBLEM TO BE SOLVED: To provide a linear guide device in which a variation in amounts of a lubricants that are supplied to right and left rolling element rolling paths is hardly generated even if inclination is formed between the rolling element rolling paths on both right and left sides to cause vertical differences, and furthermore, an adjustment mechanism for the amounts of lubricants is simple, and hardly cause disorder, and both lubrication oil and grease can be used as lubricants. <P>SOLUTION: Near the central position, in right-left direction, of a rear surface of an end cap 2B, a fuel supply opening 23 that extends from a fuel supply nipple 22 on a front side is opened. A fuel supply path 21 which branches to the right and left from the fuel supply opening 23 for extension is made to communicate with bending paths 16 on right and left, respectively. A valve 40 is provided in the middle position of the fuel supply path 21. The valve 40 is formed of an elastic material. When the pressure of the lubricant L that is introduced between the fuel supply nipple 22 of the fuel supply path 21 and the valve 40 is equal to or higher than a predetermined value, elastic deformation causes an open state, so that the lubricant L is made to pass to the lower stream side. As the pressure increases, an open degree increases. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
