Abstract
A motion guide device has a moving block mounting surfaceof an end plateformed in a planar shape and a thinned-down portionformed in an opposing moving block mounting surfaceMoreover, in this motion guide device, a lubrication pathincludes: a first lubrication pathformed extending in a horizontal direction from a surface of side surfaces parallel to a longer direction of a track railin the end plateto a central portion of the end plate; a second lubrication pathformed in the central portion of the end plate; and a third lubrication pathconnected to the second lubrication path and formed in a groove shape in the moving block mounting surfaceof the end plateand, moreover, the first lubrication pathis formed in a hollow shape continuous to inside a built-up portionappended to the thinned-down portionof the end plateHaving such a configuration enables this motion guide device to achieve an average dispersal of lubricant to each of rolling element circulation paths regardless of mounting position of a greasing nipple with respect to the end plate, type of lubricant, and so on.
