    • In an escalator (1) having a lot of steps (2) connected to be an endless chain and moved, means for shifting a rotation locus of step forward wheels (23) at both end portions toward end portions of the escalator than a rotation locus of the chain (8) is provided. A forward wheel guide means for guiding so as to extend, at both end portions of the escalator, a straight distance between forward wheels of adjacent two steps, which distance tends to be shortened by the chain drawing an arc at the both end portions is provided. By those constructions, interference between adjacent steps is hard to occur even if a rotation diameter of the steps at each end portion of the escalator is made small. Therefore, the rotation diameter of the steps can be made smaller than a conventional one and the escalator thickness size (H) can be made small.
    • 一种自动扶梯(1),其与连接到环形链(8)的多个台阶(2)一起移动,其中设置有前轮引导装置,其适于增加直线上的距离,所述距离将在链条 8)在两个相邻台阶(2)的前轮(23)之间在自动扶梯的两端部(11,12)处弧形运动。 自动扶梯还设置有用于沿着自动扶梯的两个端部(11,12)处的转向台阶的后轮(23a)和后轮(8a)之间的转向部分 8),其在自动扶梯的两端部朝向自动扶梯的端部的外边缘。 由于这种布置,即使当自动扶梯的两个端部(11,12)处的台阶(2)的转动半径减小时,相邻台阶(2)之间的干涉也很少发生。 这使得台阶(2)的转动半径可以设定为小于常规自动扶梯的台阶转动运动的半径,自动扶梯(1)的上部和下部之间的距离(H)将被减小 。
