PURPOSE:To prevent corrosion damage to a hinge by mounting and fixing one end of a tabular protective cover having the height enough to cover the hinge when a rear gate is opened to the bottom part on the rear side of a waterproof wall. CONSTITUTION:A protective cover 7 is a board formed by the same material as other members and having the same width as a track liner 1, and its one end is mounted swingably to the lower part on the rear side of a waterproof wall 5 or near the rear end part of the track liner 1 with a hinge 8. Thus, when a rear gate 21 of the track liner is closed, the protective cover 7 is closely held between the rear gate 21 and the waterproof wall 5, and seals the rear end of the track liner 1 to make the inside of the track liner just like a water tank whose upper side is open to the exterior. On the other hand, when the rear gate 21 is opened, the protective cover 7 falls down and covers a hinge 23 of the rear gate 21, so that water leaked out from the track liner 1 is discharged outside along the surface of the protective cover 7, and thereby the hinge 23 is not directly splashed with water. |
