PROBLEM TO BE SOLVED: To provide a filter structure for a water infiltration inlet which makes a filter storage container surely bonded and fitted into an infiltration cylinder, enables the filter storage container to be pulled out with ease, hardly causes the deformation or offset of a filter, facilitates the storage and takeout of the filter, and is advantageous to maintenance, and simplified in constitution. SOLUTION: In the filter structure for the water infiltration inlet, respective openings of two-part split bodies of upper and lower frame bodies 11 and 12 which have approximately lateral U-shaped longitudinal cross sections and peripheries of which are inclined, face each other in the filter which is arranged at the upper end of the infiltration cylinder 4 erected in an opening of a bottom plate 7 of a water inlet 2, the filter storage container 10 for housing the filter 20 is constituted in both the frame bodies, a radially-protruded flange 13 is formed in the opening of each of the frame bodies, a support 17 with a bolt hole is formed in the central portion of each of the frame bodies, a bolt 23, which has a hook fitting 22 locked to an upper end, and is inserted through both the bolt holes, the hook fitting abuts on the one end of the support, and a tip of the bolt is tightened at the other end of the support by a nut 25.
