<p>PROBLEM TO BE SOLVED: To prevent the tumbling of the rail of a branching device. SOLUTION: A rotary shaft 31 is installed under a movable guide rail 21a in such a way as perpendicularly intersecting the longitudinal direction of the rail and is fitted with cams 35a, 35b which are engaged by a lock device 36 situated under the guide rail 21a. To move the guide rail 21a for branching, this shaft 31 is rotated so that the cams 35a, 35b are separated from the lock device 36. After movement of the guide rail 21a, the shaft 31 is rotated, and one of the cams 35a (35b) is engaged by the lock device 36. This prevents the guide rail 21a from tumbling by the force generated with the travel of a rolling stock.</p> |
