Abstract
A linear guide apparatus comprises a rail and a bearing block movable in the longitudinal direction of the rail. The rail has a ground outside face. First raceway groove is formed on the outside face. Second raceway groove is formed on an inside face of the bearing block. A worked surface is formed by grinding on that portion of the inside face of the bearing block which is situated between the second raceway groove and a base portion. The worked surface and the outside face of the rail constitute a labyrinth seal portion, which serves to prevent foreign substances from getting into the raceway grooves. The worked surface and the second raceway groove of the bearing block are ground simultaneously.
