PROBLEM TO BE SOLVED: To provide a rail coupling unit provided between linear rails, forming a curved carrying passage on the coupling portion, and changing the curvature radius of the carrying passage with a simple structure. SOLUTION: In the rail coupling unit 1, by a simple operation rotating rotating plates 12 to 15 in regard to a base plate 11, the curvature radius of the curved carrying passage formed by the base plate 11 and the rotating plates 12 to 15 can be adjusted. Consequently, the rail coupling unit 1 can be installed to various positions for connecting the linear carrying rails, and have a high level of general versatility. COPYRIGHT: (C)2006,JPO&NCIPI
