    • PROBLEM TO BE SOLVED: To provide a costless expansible joint device by which trains can safely travel to prevent wheels from entering from a position lacking in a gauge line of the expansible joint of railroad rails and from running on to the rails and by which the longitudinal distance of the ends of the forward and rearward rails can be shortened and further, easily carry out installation works and maintenance works without installing equipment such as guide rails. SOLUTION: The joint thin end 1' of a forward rail end 1 and the joint thin end 2' of a rearward rail end 2 are formed parallelly to the longitudinal direction of rails respectively. The joint thin ends 1', 2' are put parallelly to the longitudinal direction of the rails and closely to each other to form an expansible joint 3. One end of a guide plate 5 guiding a wheel to a gauge line (a) is fixed to the end 2 of the rearward rail. The guide plate 5 is installed in a position (b) lacking in a gauge line of the expansible joint 3 in a state that the rail ends 1, 2 are expansibly or contractibly transferable in the longitudinal direction of the rails so that the other end of the guide plate 5 and the joint thin ends 1', 2' are pinched loose by rail presses 8, 8'.
