Abstract
Official abstract text for this publication.
A linear motion guide apparatus that is easily assembled is provided. The linear motion guide apparatus includes: two guide rails that are movable relative to each other in a longitudinal direction thereof via at least one rolling element; and a cage configured to hold the rolling element and hold a gear engaging with a meshing portion provided to at least one of the two guide rails. The cage includes: a first split body in which a rolling element holding portion that holds the rolling element and a gear holding portion that holds the gear are integrally formed; and a second split body in which a rolling element holding portion that holds the rolling element and a gear holding portion that holds the gear are integrally formed. The first split body and the second split body are joined to each other.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A linear motion guide apparatus comprising: two guide rails that are movable relative to each other in a longitudinal direction thereof via a plurality of rolling elements; and a cage configured to hold the rolling elements and hold a gear engaging with a meshing portion provided on at least one of the two guide rails, wherein the cage includes: a first split body and a second split body, each of the first and second split bodies having a rolling element holding portion that holds the rolling element and a gear holding portion that holds the gear integrally formed therein, the first split body and the second split body are joined to each other, each of the rolling elements is a crossed roller in which axes of adjacent rollers are perpendicular to each other, and the axis of one of the adjacent rollers and a center of another roller are placed on substantially a same plane as a mating surface between the first split body and the second split body. 2 . The linear motion guide apparatus according to claim 1 , wherein the first split body and the second split body are welded together. 3 . The linear motion guide apparatus according to claim 1 , wherein a gear holding surface inclined relative to the mating surface is formed on the gear holding portion of each of the first split body and the second split body. 4 . The linear motion guide apparatus according to claim 3 , wherein the first split body and the second split body are welded together.
