PROBLEM TO BE SOLVED: To provide a fluid mixer capable of scaling up while restraining an increase in a gap width, and capable of restraining vibration of a core rod passing though a pore that forms a fluid flow contraction part.SOLUTION: A fluid mixer 10 comprises: a first flow passage 11 extending in one direction; a second flow passage 12 extending in the same direction as the first flow passage; a fluid confluent part 10B provided on the fluid outflow side of the first flow passage and the second flow passage and merging a first fluid of flowing in the first flow passage and a second fluid flowing in the second flow passage; a fluid flow contraction part 10C for contracting a flow of the confluent first fluid and second fluid; and a fluid expansion part 10D into which the flow-contracted first fluid and second fluid flow. In the fluid mixer, a core rod 60 is inserted into a hole part 41 of an orifice member 40 forming the fluid flow contraction part 10C such that an annular fluid flow passage G is formed on the periphery, and the core rod 60 is supported on both sides sandwiching the hole part 41. |
