Abstract
A track rail is composed of a pair of rail members in which rolling contact surfaces for rolling bodies are formed, respectively, and a rail housing equipped with a pair of rail mounting grooves in which those rail members are fitted, respectively. Each of the rail members is fixed within a corresponding one of the rail mounting grooves via an adhesive layer. A reference projection, formed on a bottom of one of the pair of the rail mounting grooves, is in contact with a corresponding one of the rail members without the intermediary of the adhesive layer. The rail member fitted in the one of the rail mounting grooves is adhesively fixed in a state of being abutted against the reference projection. The rail member fitted in the other rail mounting groove is adhesively fixed at a predetermined distance from the reference projection.
