The locking body 750 may be supported by contacting the inner flange outer peripheral surface (400a). The locking body 750 may be in contact with the lower surface of the locking groove 500, that is, the upper surface of the upper guide wall 252. The locking body 750 can be deeply inserted into the bottom of the locking groove 500 to more stably fix the sealing member 700 to the sump housing 200.

The hanging body 750 may include a hook 760. Specifically, the hook 760 may include an insertion portion 761 and a protrusion 762. The insertion portion 761 may be formed to extend vertically. The protrusion 762 may be formed at the lower part of the insertion part 761 and provided at the lower end of the engaging body 750. The protrusion 762 may be provided to protrude from the insertion portion 761.

The protrusion 762 may protrude toward the flanges 300 and 400. The protrusion 762 may contact the inner flange outer peripheral surface (400a). In this drawing, the protrusion 762 is shown as an example protruding toward the inner flange 400, but the present disclosure is not limited thereto. For example, the protrusion 762 may protrude toward the outer flange 300.

The length at which the protrusion 762 protrudes and extends from the insertion portion 761 may correspond to the length at which the locking protrusion 410 protrudes and extends from the inner flange outer peripheral surface 400a. That is, the protrusion 762 of the hook 760 and the locking protrusion 410 of the inner flange 400 may be provided in shapes corresponding to each other, so that the locking body 750 is not easily separated from the locking groove 500. It can be prevented.

The sealing member 700 may include a connection body 770. The connection body 770 may connect the engaging body 750 and the sealing body 710. The connection body 770 may be disposed on the upper part of the inner flange 400. The connection body 770 may be in contact with the lower surface of the upper bottom wall 101 of the tub 12.

Additional fastening members may not be disposed between the sealing member 700 and the bottom wall 100 of the tub 12. That is, an additional fastening member may not be disposed on the upper part of the sealing member 700 seated on the sump housing 200.

Additional fastening members may not be disposed between the upper surface of the outer flange 300 and the lower surface of the bottom wall 100 of the tub 12 facing the upper surface of the outer flange. Additional fastening members may not be disposed between the upper surface of the sealing member 700 and the lower surface of the bottom wall 100 of the tub 12 facing the upper surface of the sealing member 700.

That is, without a separate fastening member for stably fixing the sealing member 700 to the sump housing 200, sealing is achieved through the locking groove 500 and the first coupling portion 261 and the second coupling portion 711. The members 700 can be stably coupled.

By omitting the construction of fastening members, parts can be simplified and manufacturing costs can be reduced. Additionally, the tub 12 and the sump housing 200 can be coupled more closely, thereby reducing the top and bottom volume.

The upper surface of the sealing member 700 and the lower surface of the bottom wall 100 may be spaced apart from each other or may contact each other by force applied in the axial direction.

The material of the sealing member 700 may include EPDM or silicon, so it can be easily compressed and be resistant to heat.

Figure 14 is a diagram showing a sealing member seated in the sump housing receiving force in the vertical direction by the tub. Figure 15 is a diagram showing a sealing member seated in the sump housing receiving an inward force from the tub. Figure 16 is a diagram showing a sealing member seated in the sump housing receiving an outward force from the tub.

Referring to FIG. 14, when the tub 12 is coupled to the sump housing 200, the connection side wall 102 rubs against the side of the sealing body 710, and force is applied to the sealing member 700 in the vertical direction. You can. 15 and 16, when the tub 12 is coupled to the sump housing 200, the lower bottom wall 103 rubs against the upper surface of the sealing body 710 and moves in the left and right directions against the sealing member 700. Force may be applied.

At this time, since the locking body 750 of the sealing member 700 is inserted into the locking groove 500, the sealing member 700 can be prevented from being separated from the sump housing 200. Specifically, the locking body 750 is supported by contacting the inner peripheral surface 300b of the outer flange, the protrusion 762 of the hook 760 is in contact with the outer peripheral surface 400a of the inner flange, and the locking protrusion 410 of the inner flange 400 ) By preventing the vertical movement of the protrusion 762, the locking body 750 is fixed to the locking groove 500 and can prevent movement of the sealing body 710. Additionally, the second coupling portion 711 of the sealing body 710 is coupled to the first coupling portion 261 of the lower guide wall 253, thereby preventing movement of the sealing body 710. That is, the sealing member 700 according to the present disclosure can be stably seated and easily fixed to the sump housing 200.

In the above, specific embodiments are shown and described. However, it is not limited to the above-described embodiments, and those skilled in the art can make various changes without departing from the gist of the technical idea of the invention as set forth in the claims below. .
