An over-displacement preventing means for connecting the receiving device, the anti-sway device and the receiving device arranged opposite to the vertical plane, and for preventing the displacement of the both in the separating direction within a predetermined range; And a collision plate which is mounted on each of the opposing surfaces so as to oppose each other and arranged at a position corresponding to the center axis of the over-displacement prevention means.

Thus, the load due to the vertical displacement of the main frame does not act on the fixed body, and the displacement of the main frame in the fixed body direction is applied to the longitudinal direction of the main frame via one collision plate of the steady rest and the support. It is suppressed by the fixed body provided on the side of the middle part. Further, the displacement in the direction in which the main frame is separated from the fixed body is prevented within a predetermined range by the excessive displacement prevention means.

Therefore, even if the main frame is bent and the longitudinal middle portion is displaced downward, the load due to the downward displacement of the main frame does not act on the holder, the fixed body, etc. When the main frame is displaced in the direction of the fixed body due to an earthquake or the like, there is an effect that the steady rest and the receiving member hit each other to suppress the displacement of the main frame. In addition, there is no supporting member disposed below the longitudinal middle part of the main frame, and in the case of a building with a low floor, obstacles in the space above the passengers of other passenger conveyors disposed below the main frame are not disposed. There is an effect of eliminating the installation restriction for the purpose.

Further, the displacement in the direction in which the main frame is separated from the fixed body is prevented within a predetermined range by the over-displacement preventing means, thereby preventing a trouble caused by the main frame being excessively displaced in the direction in which the main frame is separated from the fixed body. Has the effect of doing Further, a collision plate is provided, one of which is mounted on the opposing surface of the steady rest and the other of the receiving member, which are opposed to each other, and which are arranged at positions corresponding to the central axis of the over-displacement prevention means. This has the effect of facilitating the adjustment work of mounting the collision plates at predetermined positions with respect to the steady rest and the receiver .
