Summary:PROBLEM TO BE SOLVED: To provide a gate valve device that can effectively prevent the occurrence of hole tone to produce less noise.SOLUTION: A vortex flow generation ring 17 has a plurality of protrusions 22 at a predetermined interval in the circumferential direction, each protrusion 22 being arranged obliquely with respect to the flow direction of fluid 19 flowing through a flow path 12. The vortex flow generation ring is mounted to a valve body 15 so as to face an entry-side flow path 12.
