A second support is disposed parallel to and at a predetermined interval from the first support. The first and second supports have the same shape. A respective inner end of first steel members is fixed to an upper end of the first support, and outer ends of the first steel members extend perpendicularly to the direction of the crosswalk. Second steel members are disposed parallel to and at a predetermined interval from the first steel members. The first and second steel members have the same shape. A laser curtain beam radiating device is disposed on an underside of an outer end of one of the first and second steel members, and radiates a laser curtain beam in the direction of the crosswalk.
