The upper surface of the floor 102 is slightly inclined downward toward the edge 1021. In FIG. 3 and FIG. 4A, the inclination direction (flow direction) of the upper surface of the floor 102 is indicated by a broken-line arrow.

  The edge 151 of the lid 15 is an edge on the side close to the drainage groove 103 (side facing the drainage groove 103) in a state where the lid 15 is fitted in the recess 104. The edge 151 is straight along the longitudinal direction D1.

  The drainage groove 103 can be divided into one end portion 1031 in the longitudinal direction D1 and a groove main body portion 1032 excluding the one end portion 1031. The groove main body portion 1032 has a bottom surface inclined downward toward the one end portion 1031. The bottom surface of the groove body 1032 may be a downward slope as a whole.

  The one end 1031 is a portion adjacent to the recess 104 in the drainage groove 103. In other words, the one end portion 1031 is a portion of the drainage groove 103 that faces the edge 151 of the lid 15 fitted in the recess 104.

  The groove main body portion 1032 is a portion adjacent to the floor portion 102 in the drainage groove 103. In other words, the groove main body portion 1032 is a portion of the drainage groove 103 facing the edge 1021 of the floor portion 102. In FIG. 3 and FIG. 5A, the inclination direction (flow direction) of the groove main body portion 1032 is indicated by a broken-line arrow.

  The bottom surface of the one end portion 1031 of the drainage groove 103 is constituted by an inclined surface 105 that is inclined downward toward the concave portion 104. The inclined surface 105 can be divided into a plurality of (three in this embodiment) surfaces 1051, 1052, and 1053 along the longitudinal direction D1.

  The plurality of surfaces 1051, 1052, and 1053 of the present embodiment are a first surface 1051, a second surface 1052 that is located on one side of the longitudinal direction D1 with respect to the first surface 1051, and a length with respect to the first surface 1051. A third surface 1053 is located on the other side of the direction D1.

  As shown in FIG. 6, the first surface 1051, the second surface 1052, and the third surface 1053 are respectively inclined downward toward the drain port 101 that opens at the center of the recess 104. The inclination directions of the first surface 1051, the second surface 1052, and the third surface 1053 are different from each other. The inclination directions (the direction in which water flows) of the first surface 1051, the second surface 1052, and the third surface 1053 are directions that approach each other downward.

  In FIG. 6, the inclination directions of the first surface 1051, the second surface 1052, and the third surface 1053 are indicated by broken-line arrows. The inclined surface 105 (the first surface 1051, the second surface 1052, and the third surface 1053) is inclined so as to collect water toward the drain port 101 as a whole.

  In a state where the lid 15 is fitted in the recess 104, a space S1 (see FIG. 4A, FIG. 4B, etc.) covered with the lid 15 is formed between the lid 15 and the drain port 101. The space S1 communicates with the drain port 101.
