A liquid surface level sensor includes a plurality of piece portions provided at both ends of the liquid surface level sensor in a width direction, and a plurality of elastically deformable hook portions formed to elongate from both end sides in a first height direction. A pump holder includes a plurality of claw portions formed in a claw shape by bending front end sides in an intra-width direction of the liquid surface level sensor, and a plurality of convex portions on a side of the first height direction of the plurality of claw portions. A plurality of hook portions is elastically deformed in contact with the plurality of convex portions by sliding the liquid surface level sensor in a second height direction, the plurality of hook portions gets over the plurality of convex portions and restores from an elastically deformed state by further sliding the liquid surface level sensor. |
