<p>PROBLEM TO BE SOLVED: To release a vehicular shock at the time of vehicular collision to a gate arm, prevent the damage of a crossing gate itself and the danger by the big spring back of the gate arm and dispense with the restoration work by a watch, etc., even if a wind pressure and the slight contact to the gate arm of the vehicle are generated. SOLUTION: A crossing gate 1, 1 has a turning part turned and driven around a horizontal axis and an gate arm 13 supported for the turning part. The arm 13 is turned vertically by the turning of the turning part and the traffic of a vehicular passage 3 is opened/closed. The arm 13 is supported foldably for the turning part in a vehicular advance direction X and energized by an energizing member into the hot folded state. The crossing gate 1 is provided with such releasable holding mechanism that when the folding angle of the arm 13 is a prescribed angle or less, the folded state of the arm 13 is not kept and also when the folding angle of the arm 13 is bigger than the prescribed angle, the folded state of the arm 13 is kept.</p> |
