  As shown in FIG. 4, the cover member 40 (hole cover portion 42) extends from the through holes 31 </ b> A and 31 </ b> B so as to overlap upward, and extends downward from the outer peripheral end of the extension portion 43. And four ribs 45 projecting downward from the lower surface of the extending portion 43 and extending along the peripheral wall portion 44.

  As shown in FIG. 2, the extending portion 43 has a rectangular shape in plan view, and extends along the floor surface 11 </ b> A of the floor carpet 30. With such a configuration, the cover member 40 has the extending portion 43 disposed in front of the seat cushion of the second seat 13, but does not easily get in the way of a person sitting on the second seat 13. The design is difficult to damage. The peripheral wall portion 44 extends in a U shape in parallel with the rising portions 36A and 36B outside the rising portions 36A and 36B so as to surround the through holes 31A and 31B from the front side of the vehicle and the outside in the vehicle width direction. .

  As shown in FIG. 4, the cover member 40 is arranged so as to abut against the hole edges 35 </ b> A and 35 </ b> B of the floor carpet 30. Specifically, in the cover member 40, the lower surface of the peripheral wall portion 44 is in contact with the floor surface 11A, and the lower surface of the rib 45 is in contact with the upper surface portions 37A and 37B. With such a configuration, a double seal structure is formed between the floor surface 11A of the floor carpet 30 and the peripheral wall portion 44, and between the upper surface portions 37A and 37B and the rib 45, so that the liquid passes through the hole. It is possible to suitably restrict the movement to the 31A, 31B side. The region where the four ribs 45 are set extends over a wider range than the upper surface portions 37A and 37B, and due to the assembly error between the cover member 40 and the floor carpet 30, the rib 45 and Generation | occurrence | production of the situation that upper surface part 37A, 37B does not contact | abut can be suppressed.

  The cover member 40 is arranged in a state in which the peripheral wall portion 44 and the rib 45 wrap with the floor carpet 30 in the vehicle vertical direction. According to such a configuration, the sealing property between the cover member 40 and the floor carpet 30 can be enhanced by the reaction force of the floor carpet 30. Specifically, the peripheral wall portion 44 is disposed in a state where the floor surface 11A of the floor carpet 30 is compressed and submerged from the floor surface 11A. The ribs 45 are arranged in a state where the upper surfaces of the upper surface portions 37A and 37B are compressed and submerged from the upper surfaces. Further, the rib 45 presses the upper surface portions 37A and 37B downward so that the entire upper surface portions 37A and 37B have the inner peripheral surface side as a free end and the lower side with the opposite side of the inner peripheral surface as an axis. It is configured such that the upper surface portion 37 abuts against the upper surface portions 37A and 37B in a state where the upper surface portion 37 is slightly rotated and generates a force for elastic recovery.

  Below the portion of the floor carpet 30 where the peripheral wall 44 abuts, a cushion layer 26 is disposed as an interposed member interposed between the floor carpet 30 and the battery unit 20. In other words, the portion with which the peripheral wall 44 abuts is supported by the battery unit 20 via the cushion layer 26 from below. According to such a configuration, deformation of the floor carpet 30 in the direction of escaping downward from the peripheral wall portion 44 is suppressed, and the sealing performance between the cover member 40 and the floor carpet 30 can be enhanced.

Then, the effect | action of this embodiment is demonstrated with reference to FIG.
Of the liquid spilled on the floor surface 11A of the floor carpet 30, the liquid moving toward the through holes 31A and 31B is first blocked by the peripheral wall portion 44 of the cover member 40, and is moved toward the through holes 31A and 31B. Restricted to move.

  When a part of the liquid blocked by the peripheral wall portion 44 passes between the cover member 40 and the peripheral wall portion 44, the liquid is further blocked by the rising portions 36A and 36B, and the through holes 31A and 31B side. Is restricted from moving to.

  When the liquid blocked by the rising portions 36A and 36B overflows from above the rising portions 36A and 36B, the gap between the rib 45 and the upper surface portions 37A and 37B is sealed. The liquid is restricted from moving toward the through holes 31A and 31B.

  And even if the liquid which reached the inner peripheral surface of the through-hole 31B falls downward, the through-hole 31B (through-hole 31A) is the front inner peripheral surface 32B (located on the battery unit 20 side). Since the front inner peripheral surface 32A and the outer inner peripheral surface 33A) are located outside the battery unit 20 in the horizontal direction, the liquid falls to the side of the battery unit 20 and the situation where the liquid unit 20 is applied to the battery unit 20 occurs. Can be suppressed. Further, the rising portion 36B is provided along the front inner peripheral surface 32B and the outer inner peripheral surface 33B, and is not provided for the rear inner peripheral surface 34B. The vehicle moves rearward along 36B and falls downward from the rear inner peripheral surface 34B located on the side far from the battery unit 20. As a result, the amount of liquid falling downward from the front inner peripheral surface 32B (the front inner peripheral surface 32A and the outer inner peripheral surface 33A) is reduced, and more preferably, the liquid falling downward from the through hole 31B is applied to the battery unit 20. The occurrence of the situation can be suppressed.

Then, the effect of this embodiment is demonstrated.
According to the present invention, since the rising portion 36 rising from the floor surface 11A is formed below the cover member 40, the second sheet 13 (cover member 40) mounted on the floor surface 11A side after laying the floor carpet 30 is formed. Thus, the rising portion 36 can be formed and the rising portion 36 is not visually recognized from the passenger compartment. And the rising part 36 can block the liquid falling on the floor surface 11A and going to the through holes 31A and 31B. In addition, the inner peripheral surface (front inner peripheral surface 32A, outer inner peripheral surface 33A, and front inner peripheral surface 32B) of the through hole located on the rising tip side of the rising portion 36 is positioned outward from the battery unit 20 in the horizontal direction. Therefore, even if the liquid dropped on the floor surface 11A falls downward from the through holes 31A and 31B, it can fall to the side of the battery unit 20. As a result, it is possible to suppress the occurrence of a situation where liquid is applied to the battery unit 20 without impairing the appearance of the floor surface 11A.

  In the present embodiment, a structure for blocking the liquid on the floor surface 11A is provided integrally with the existing floor carpet 30 and the cover member 40 (the rising portion 36, the upper surface portion 37, the peripheral wall portion 44, Ribs 45 and the like), and the cost can be reduced as compared with the case where the structure for blocking is formed by separate parts. Further, in the present embodiment, the arrangement of the front inner peripheral surface 32A, the outer inner peripheral surface 33A, and the front inner peripheral surface 32B is made outward from the battery unit 20 in the horizontal direction, and thus falls from the through holes 31A and 31B. Since the liquid falls to the side of the battery unit 20, for example, the cost is lower than when a separate guide member or the like for guiding the liquid dropped from the through holes 31 </ b> A and 31 </ b> B to the side of the battery unit 20 is provided. Can be reduced.

  Further, in the present embodiment, the rising portion 36 can be covered with the existing cover member 40 for covering the mounting portion 16. For example, the rising portion can be formed by hitting a leg of a person sitting on the second seat 13. There is no possibility that the standing shape of 36 will be crushed, and the ability of the rising portion 36 to block the liquid can be suitably maintained.

  In the present embodiment, the cushion layer 26 interposed between the floor carpet 30 and the battery unit 20 is disposed below the portion of the floor carpet 30 where the peripheral wall 44 of the cover member 40 abuts. For this reason, by supporting the floor carpet 30 from below by the battery unit 20 and the cushion layer 26, the sealing performance between the peripheral wall portion 44 and the floor carpet 30 can be enhanced, and more preferably on the floor surface 11A. Water that falls and moves toward the through holes 31 </ b> A and 31 </ b> B can be blocked by the cover member 40.

  Further, in the present embodiment, the existing cushion layer 26 is made to function as an interposed member. In other words, since the peripheral end portion 44 of the cover member 40 is positioned above the existing cushion layer 26, there is a separate intervention. Cost can be reduced compared with the case where a member is provided.

<Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to FIG. The cover member 140 of the present embodiment is different from the hole cover portion 42 of the first embodiment in the shape of the hole cover portion 142. In addition, the description which overlaps about the structure, an effect | action, and effect similar to above-described embodiment is abbreviate | omitted.

  As shown in FIG. 5, the cover member 140 (hole cover portion 142) includes a first extension portion 143 that extends upwardly with respect to the through holes 31 </ b> A and 31 </ b> B, and an outer periphery of the first extension portion 143. A descending portion 146 that descends downward from the end portion along the rising portion 36, a second extending portion 147 that extends from the lower end of the descending portion 146 along the floor surface 11 </ b> A, and a lower portion from the outer peripheral end of the second extending portion 147 And a peripheral wall portion 144 extending in the direction. In other words, the cover member 40 has a shape extending along the upper surface portions 37A and 37B, the rising portions 36A and 36B, and the floor surface 11A of the floor carpet 30. In the present embodiment, the rib 45 that contacts the upper surface portions 37A and 37B is not provided, and the lower surface of the first extending portion 143 is configured to contact the upper surface portions 37A and 37B.

  According to the present embodiment, even if the cushion layer 26 is disposed at a position away from the through holes 31A and 31B, the second extending portion 147 is extended to be below the floor carpet 30. The peripheral wall 44 can be brought into contact with the portion where the cushion layer 26 is disposed. In this case, the amount by which the cover member 40 protrudes toward the vehicle interior side can be reduced according to the height of the lowering portion 146, compared to the case where the first extending portion 143 is simply extended to the cushion layer 26 side. .

  Furthermore, according to this embodiment, since the rib 45 is not provided, the amount by which the cover member 140 protrudes toward the vehicle interior side can be reduced according to the height of the rib 45.
