<P>PROBLEM TO BE SOLVED: To provide a vehicle passage intercepting machine that can quickly recover a blocking bar after a release operation with a simple constitution. <P>SOLUTION: A vehicle passage intercepting machine includes a recovery driving section 61, a blocking bar 30 which is rotated between a blocking position for blocking passing of a vehicle and a permission position for permitting advancing of the vehicle by the recovery driving section 61 to perform an opening/closing operation, a release shaft 22 for rotating the blocking bar 30 in a release direction for releasing impact by the vehicle, and a transmission mechanism 70 for transmitting rotation of the recovery driving section 61 to the release shaft 22 only when the blocking bar 30 is rotated in the release direction. The rotation of the recovery driving section 61 causes the release shaft 22 to rotate, which allows rotation of the blocking bar 30 in a recovery direction which is a direction opposite to the release direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
