Abstract
A dust collecting device for collecting cutting chips into a dust collecting container is provided. A back-flow preventing wall(s) is fixedly disposed on a flow path member defining a flow path between a machining apparatus and the dust collecting container. The back-flow preventing wall(s) is configured to decrease a cross sectional area of a flow path part defined by the flow path member in a downstream direction with respect to the flow of the air containing the cutting chips toward the dust collecting container.
