A dust collecting mechanism is a dust collecting mechanism that sucks up and collects dust generated by a machining apparatus, including a suction section for sucking up the dust by exerting sucking force on a workpiece, a sucking force generating mechanism for generating sucking force acting on the suction section, and a suction pipe enabling communication between the suction section and the sucking force generating mechanism, wherein the suction pipe includes an opening section extending from the inside to the outside thereof and a shutter mechanism for opening and closing the opening section, and wherein the pressure inside the suction pipe can be switched between an atmospheric pressure state and a sucking force generating state by causing the shutter mechanism to open or close the opening section while sucking force is generated inside the suction pipe by operating the sucking force generating mechanism.
