Abstract

PURPOSE:To reduce a tread step difference by installing a lower rail, forming a low locus in a conveying locus in a platform rail of a footboard, in a floor lower position between the platform rail and a turnover rail. CONSTITUTION:Each of lower rails 8a, 8b is installed in a floor lower position between platform rails 6a, 6b and a turnover rail 5b and connected to these platform rails 6a, 6b. Each of lower surfaces 8a1, 8b1, guiding both front and rear wheels of a footboard 3, is formed in the lower rails 8a, 8b. Accordingly, when the footboard 3 moving after being guided by the platform rails 6a, 6b has entered beneath a floor 7, it is operated to go down by the lower surfaces 8a1, 8b1 of the lower rail 8. Consequently, a step difference A between a tread 3a and the floor 7 is reducible, thus boarding and alighting for a wheelchair or the like comes easy.
