Zusammenfassung:To prevent water leakage from a pump.SOLUTION: A pump 1 comprises an impeller 21, a main body part 3 comprising a driving source, a pump casing 22 constituted by a member having elasticity, and a strainer 23 fastened together with the pump casing to the main body part by a bolt 24. The strainer has a bottomed cylindrical shape comprising a bottom part 231, and a cylindrical wall 232 erected from a periphery of the bottom part toward the main body part. While the strainer is fastened to the main body part, a pressing part (a protrusion 236) provided in the strainer presses a peripheral edge part of the pump casing against the main body part.SELECTED DRAWING: Figure 2 【課題】ポンプの水漏れを防止する。【解決手段】ポンプ１は、羽根車２１と、駆動源を有する本体部３と、弾性を有する部材によって構成されたポンプケーシング２２と、本体部に対して、ボルト２４によりポンプケーシングと共に共締めされたストレーナ２３と、を備える。ストレーナは、底部２３１と、底部の周縁から本体部に向かって立設する筒壁部２３２とを有する有底筒状である。ストレーナを本体部に締結している状態で、ストレーナに設けた押圧部（突起２３６）が、ポンプケーシングの周縁部を本体部の方へ押し付ける。【選択図】図２
