Inside a quench box 22 are formed a cooling tube housing chamber 41, an upper connection path 42, and a lower connection path 43. The cooling tube housing chamber 41 houses therein a plurality of cooling tubes 21 to oppose spinnerets 13 of a spinning beam 2, and these cooling tubes 21 are arranged to form two rows in the crosswise direction in a staggered manner. The cooling tube housing chamber 41 has, at the lower end portions of wall surfaces 41a and 41b, a first connection port 45 and a second connection port 46. The first connection port 45 is connected to an upper connection path 42 which is connected to a duct 60 and extends in the crosswise direction.
