<p>PROBLEM TO BE SOLVED: To provide a chain gate which reduces warning light replacing frequency, allows the driver of a vehicle to see warning lights with ease regardless of the position relation between the vehicle and gateposts and makes it possible to recognize the ascending and descending motions and the position of a chain, etc., by the warning lights. SOLUTION: A chain gate A comprises, a chain, or the like 2 stretched between two gateposts 1 installed with a specified interval between them enough to allow vehicles to pass through at height to allow the chain, or the like 2 to prevent vehicles from passing through between the gateposts 1 and the chain, or the like 2 vertically moving by the operation of a motor, which is installed in at least one gatepost 1. Warning lights 51a and 51b comprising two types of light emitting diodes of different colors alternately and a plurality of light emitting diodes arranged are provided specified length at positions in the outer peripheral surface in the peripheral direction so as to be able to see from different directions. These warning lights flash or light in one color when the chain, or the like 2 is in lifting and while the chain, or the like 2 is in contact with the ground allowing vehicles to pass through, the lights flash or light in another color.</p> |
