<p>PROBLEM TO BE SOLVED: To provide a conveyor belt for a shot blast device capable of extending service life of the belt in which crack is hardly generated on a through-hole penetrating toward an inner face from an outer face.SOLUTION: Plural through-holes 5 penetrating toward an inner face 3a from an outer face 2a of a conveyor belt 1 are formed so that their inner diameters d1 become smaller as going to the inner face 3a from the outer face 2a for making them become inner diameters d. In the other embodiment, the through-holes 5 are formed into an oval or an ellipsoidal shape in which inner diameters dL in a longitudinal direction of the belt are relatively large.</p> |
