<P>PROBLEM TO BE SOLVED: To provide a vehicle passage crossing gate which ensures quick returning of a blocking bar after releasing operation. <P>SOLUTION: A vehicle passage crossing gate includes a blocking bar 30 for opening/closing operations, which is rotated between a block position S at which the vehicle passage is blocked and a permission position K at which the vehicle passage is permitted, a release shaft that rotatably supports the blocking bar 30 toward a release direction T1 that releases impact from the vehicle, a return drive part 40 that rotates the blocking bar 30 in the released state toward a return direction T2 opposite the release direction T1, and an assisting return drive part 80 that applies torque toward the return direction T2 to the blocking bar 30 when the blocking bar 30 rotating in the return direction T2 reaches a predetermined position before it is brought into a non-release state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
