The present invention relates to a device for preventing corrugated pipe bending damage for a vacuum cleaner. This is to prevent bending of the corrugated pipe by being spirally formed in the ridge and trough and mounted at the end of the flexible corrugated pipe fitted to the corrugated pipe connector of the vacuum cleaner. with elastic holder; a support part mounted on the corrugated pipe connector and outputting a support force; It is connected to the plurality of resilient holder and one end is linked to the support, and includes an extension link that maintains the spacing between the resilient holder and the resilient holder and the support portion. The device for preventing corrugated pipe bending damage for a vacuum cleaner of the present invention as described above suppresses excessive bending of both ends of the corrugated pipe and transfers the tensile force applied to the corrugated pipe to the corrugated pipe connector, thereby effectively preventing damage to the corrugated pipe and extending the lifespan there is.
