According to the present invention, a wear-resistant lagging material is provided in a lining material coated on a rotating base material of a conveyor belt rotating in a certain direction, and a longitudinal direction of the lining material is set in the rotating direction of the rotating base material. Since it is buried at a right angle to the lining material, the lining material can be sufficiently covered by the abrasion-resistant lagging material when transporting earth and sand, etc. by the conveyor belt, and the lining material can be worn down. In addition to being able to reliably prevent the rotation, the lagging material is easily adapted to the rotating direction of the rotating base material even when the rotating base material of the conveyor belt rotates while bending. Nevertheless, the bending / rotating operation of the rotating base material is not hindered through the lining material, and the conveying function by the conveyor belt can be reliably secured.

In addition, the rugging material for abrasion resistance has an upper portion formed into a narrow flat plate having a fixed width, and a vertical plate-shaped buried portion is integrally provided at a lower portion thereof, and a protruding portion is formed on a side surface of the buried portion. Since the engaging piece is formed integrally with the lagging material to form a recess in the rotation direction, when the lagging material is embedded in the lining material, the lining material enters the recess and In the engaged state, the lining material can firmly support the lagging material, and the lagging material arranged in a direction substantially perpendicular to the rotating direction of the rotating base material can be favorably secured. In addition, the life of the conveyor belt, which is the material to be worn, can be greatly extended, and the efficiency of the work of transporting earth and sand can be improved.
