PURPOSE: To improve setting and taking-out properties of a dust collecting bag by fixing it on the front wall of a dust collecting room and the fixing face of a check valve brought into contact with a mouth core is inclined backward in accordance with the direction from the upper part to the lower part.
CONSTITUTION: A mouth core 34 is fixed on a dust collecting bag 24 in a dust collecting room 25 and is held by fitting it to a check valve 36. The check valve 36 is inclined in such a way that it comes to the front side of a main body in accordance with the direction from the lower part to the upper part and the mouth core 35 of the dust collecting bag 24 is temporarily fixed by a channel 38 formed on the lower main body and a bag mouth press 39 for holding the upper part of the mouth core 35. In addition, as a slope is formed to the check valve 36, the mouth core 35 is obliquely fixed along it. In addition, as the channel 38 holding the lower part of the mouth core 35 can be positioned on the rear side in the main body of an electric vacuum cleaner, when the dust collecting bag 24 is held, it is easy to be watched and uncorrect set of the dust collecting bag 24 can be solved.
