PROBLEM TO BE SOLVED: To provide an escape crank for a railroad turnout capable of reducing inability of changeover of the turnout.
SOLUTION: When a link 11b is operated in a D direction and an auxiliary arm 14e is brought into contact with a contact surface 13, a crank 14a is forced to rotate and a rotary body 14b is fitted in a changeover hole 13c. When the crank 14e further rotates, a rod 9a starts operating in a B direction, a tongue rail is separated from a stock rail and the turnout starts changeover. A load generated at the changeover of the turnout 1 acts on the point P1 of action of the crank 14a, and the load of the same magnitude as above is transmitted from the point P2 of action to a driving part 13. As a result, unlike the conventional escape crank, the load applied to a driven part 14 is not amplified near the middle of a stroke of an operation rod nor transmitted to a side of the driving part 13, and the inability of the changeover of the turnout 1 can be reduced.
