Further, instead of using a ridge that can be erected from the bottom surface of the sump, the detachment preventing portion is formed, for example, by bulging a portion of the bottom surface of the sump that is located on the opposite side of the pump from the suction pump tip end portion. The part is configured to be a retaining portion, and the shape and arrangement of the retaining portion can be arbitrarily set as long as the tip end portion of the suction filter can be pressed against one end edge of the raised portion to prevent the suction filter from falling off.

另外,在所述實施形態中,藉由使樹脂製的儲槽的底部隆起而形成的突條來形成防脫部,但亦可將本發明應用於藉由各種材質形成的儲槽,例如藉由焊接或板金加工而於金屬製的儲槽的底面設置防脫構件。Further, in the above-described embodiment, the retaining portion is formed by a ridge formed by bulging the bottom of the resin storage tank, but the present invention can also be applied to a storage tank formed of various materials, for example, A retaining member is provided on the bottom surface of the metal storage tank by welding or sheet metal processing.

此外,可於不影響本發明宗旨的範圍內進行各種變更。Further, various modifications can be made without departing from the spirit and scope of the invention.
