More specifically, the present invention relates to a dust bag for an electric vacuum cleaner that can be easily attached to a dust collecting portion of various types of so-called paper pack type electric vacuum cleaners (hereinafter, simply referred to as an electric vacuum cleaner).

[Conventional technology and its problems]

2. Description of the Related Art In recent years, various dust collecting bags having various shapes have been developed as dust collecting bags that can catch dust sucked by an electric vacuum cleaner.

However, when inserting these dust-collecting bags into the dust-collecting part of different types of vacuum cleaners, the dust-collecting bag body is caught in the dust-collecting part, or after inserting the dust-collecting part lid part. In some cases, the main body of the dust bag may be caught between the lid part and the dust collecting part, or may not open properly during dust collection.

[Problems to be Solved by the Invention] Therefore, the inventors of the present invention have solved the above-mentioned problems of the prior art and collected dust collecting bags even when they are attached to dust collecting portions of vacuum cleaners of different types. The dust bag body does not get caught in the dust collecting part, or when the dust collecting part lid is set after it is inserted, the dust collecting bag does not get caught between the lid part and the dust collecting part. It has been found earlier that the bag can be sufficiently opened when it is installed, and that it can collect more dust and can be easily attached to various vacuum cleaners (Practical application 61-203060).
See the specification).

Furthermore, the inventors of the present invention have conducted extensive studies and found that the top and bottom of the support have height adjusting means and recesses for the support, respectively, and that the surface of the support on which the dust-collecting bag body is not provided is provided. If you install a mounting hole on the right side of the inlet, and the dust bag body comes out only on the opposite side of the mounting hole when folded, you can attach it to the dust collecting part of various electric vacuum cleaners. We found a general-purpose dust bag and completed the present invention.
