A conveyor belt (11) is formed by coupling multiple chain links 15 aligned in a conveyance direction X. The chain link (15) is provided with multiple recess parts (15a) and first hinge parts (21) protruding in the conveyance direction X from positions between which each of the recess parts (15a) is placed. If some object hits on an outer end of the conveyor belt (11) to apply force to the first hinge part (21), a section including the first hinge part (21) and a bulging part (30) pivots about a fulcrum at an outer base end of the first hinge part (21) to deform this section. In this invention, a point of action where force acts on the conveyor belt (11) and the center of pivotal motion of the first hinge part (21) and the bulging part (30) are determined to be spaced by a relatively short distance.
