PROBLEM TO BE SOLVED: To provide a railroad crossing gate for easily responding to specifications of different interception pole lengths.SOLUTION: By preparing an auxiliary power generating unit detachable/attachable to a casing 4 of a railroad crossing gate 2 and attaching the unit, a specification corresponding to a straight interception pole can be changed to a specification corresponding to an interception pole of a long interception pole length. The auxiliary power generating unit includes a torsion coil spring 58 between a coordinated part 54 mating with an engaging part 18 fixed to the end of an interception pole rotary shaft 10 and a unit frame 56. The torsion coil spring 58 is biased by rotation of the coordinated part 54 according to the drop operation of the interception pole 14. Thus, the auxiliary power generating unit exhibits the auxiliary power for raising the interception pole 14. |
