Abstract
Official abstract text for this publication.
A trunk portion ( 13 ) of each end face of a slider body of a linear guide apparatus is covered with trunk parts ( 212 A, 212 B) of retainers ( 2 A, 2 B) in the whole width direction. End faces of both of the trunk parts ( 212 A, 212 B) are provided with a projection portion ( 212 c ) and a recess portion ( 212 d ), respectively. The end faces of both of the trunk parts ( 212 A, 212 B) are brought into contact with each other in a width direction of the projection portion ( 212 c ) and the recess portion ( 212 d ), that is a thickness direction of the trunk portion ( 13 ) of the slider body, and has a gap in a length direction (i.e., width direction of the slider). End faces of adjacent trunk parts ( 212 A, 212 B) oppose each other at a position not overlapping an oil supply opening ( 70 ). Oil grooves ( 23 ) conforming to oil grooves ( 76 ) formed on the end cap ( 7 ) are provided on end cap side faces of plate-shaped portions ( 21 A, 21 B) integrally formed with the retainers ( 2 A, 2 B).
First claim
Opening claim text (preview).
The invention claimed is: 1. A linear guide apparatus, comprising: a guide rail; a slider; and a plurality of rolling elements, wherein: the guide rail and the slider are configured to form rolling faces disposed to oppose each other for forming a rolling passage for the plurality of rolling elements, the slider includes a return passage for the plurality of rolling elements, and a direction changing path for communicating the return passage and the rolling passage, a ci…
