In addition to improving workability as compared with the case of performing at the source, the structure can be simplified and the cost can be reduced.

Although the embodiments of the present invention have been described in detail, various design changes can be made in the present invention without departing from the gist thereof.

For example, in the embodiment, a pair of upper and lower guide rollers 81, 81 are employed as guide members, but a single guide roller having a length substantially equal to the vertical length of the cleaning brush 63 may be employed. It is possible. Further, the guide member is not limited to the roller, and the upper tunnel side wall WUb
May slide. The shape of the stopper 78 is not limited to that of the embodiment, but a guide member that smoothly contacts the stopper 78 may be provided on the brush holder 61 side.

[0034]

As described above, according to the first aspect of the present invention, only by moving the gantry from the storage position to the extended position, the brush holder is automatically inclined, and the cleaning brush is inclined. Because it can be brought into contact with the wall,
Not only is workability greatly improved, but a special drive means for inclining the brush holder is not required, which can contribute to cost reduction.

According to the second aspect of the present invention,
Even if the gantry is pushed toward the retracted position by the reaction force that the guide roller receives from the tunnel wall while cleaning the tunnel wall with the cleaning brush, the movement of the link mechanism can be absorbed by the lost motion means. In addition to preventing the load from being applied, even if there are some protrusions on the wall surface of the tunnel, it is not necessary to retract the cleaning brush each time, so that the workability is improved.
