A drive pulley (not shown) is arranged near the outlet. The driving pulley is driven and rotated by a motor (not shown).

A tread belt V is wound around the pulleys 11 to 13 and the driving pulley in an endless track. When the driving pulley rotates, the tread belt V moves by being driven by the driving pulley, and the pulleys 11 to 1 move.
3 rotate in a passive manner. In addition, each pulley 11, 12
Rotate in the counterclockwise direction in FIG.
Rotates clockwise. For this reason, the tread belt V
In the upper route, the vehicle moves from the lower right to the upper left in FIG.

The pits P are partially covered by a floor plate F arranged substantially flush with the slope surface G. The opening between the floor plate F and the tread belt V is covered with the comb plate 50 and the comb C. The comb plate 50 is formed in a rectangular plate shape, and is rotatably supported by a shaft support member (not shown) near the distal end of the floor plate F in the vicinity of the base end.

The comb C is mounted near the left end of the comb plate 50 in FIG. In addition, since the force which rotates in the counterclockwise direction in FIG. 5 is applied to the comb plate 50 by gravity, the tip of the comb C
It is in a state of contact with the tread belt V. Then, even when the tread belt V is moving, the comb C is kept in contact with the tread belt V.
Although not shown in FIG. 5, a floor plate F, a comb C and a comb plate 50 are similarly provided near the exit.

In a state where the tread belt V is moving,
The user proceeds from the slope surface G to the floor plate F,
The vehicle moves to the tread belt V via the comb plate 50.

When the moving sidewalk apparatus having the above-mentioned structure is operated, snow brought in by the user adheres to the surface of the tread belt V. When the tread belt V moves, the snow attached to the surface of the tread belt V accumulates as an accumulation S between the lower surface of the comb C and the surface of the tread belt V. In an environment where the moving sidewalk device is installed, snow and ice are usually hard to melt, so that the accumulation S increases as the tread belt V moves.

[0008] Then, the comb S and the comb plate 50 may float up or the tread belt V may deviate from a predetermined track due to the accumulation S. In such a state, the moving sidewalk device cannot operate safely. Therefore, the clerk must remove this accumulation S after work. In addition, on days when there are many users, the clerk may have to stop the moving sidewalk device during business hours to remove the accumulation S.

Further, in this moving sidewalk device, Com.
In some cases, a sensor is provided for detecting that the vehicle has floated by a predetermined amount or more, and a control device for stopping the sidewalk device that moves simultaneously with the detection by the sensor is provided. In this case, when the accumulation S becomes large during operation and pushes up the comb C, the moving sidewalk device automatically stops. In other words, the moving sidewalk device may stop unexpectedly at a timing unpredictable by the attendant, which is an operational problem.

Therefore, between the tread belt V and the comb C,
An object of the present invention is to provide a moving sidewalk device that can always operate in a safe state without accumulating snow and ice.
