A dust box provided below the opening / closing lid 2, 4 is a paper-pack type bag-shaped filter housed in the dust box 3, and 5 is provided in the bag-shaped filter 4 and constitutes an opening of the bag-shaped filter 4. A configuration in which the mount 5 is accommodated by a guide in the dust box 3 and held by a holder described below in a state in which the mount 5 is opposed to a suction port to be described later and is in contact with a front-side partition wall of a main body case to be described later. It has become. Reference numeral 6 denotes a main body case that constitutes the main body 1, 6a denotes a front side partition wall that partitions the front side of the main body case 6, and 6b is formed integrally at substantially the upper center or both upper sides of the front side partition wall. This is a holding portion that holds one end of a later-described pushing spring. The holding portion 6b is formed integrally at substantially the center of the upper portion of the front side partition wall, or at both upper portions,
The other end of an extruding spring, which will be described later, is brought into contact with the upper center of the mount 5 or on both upper sides thereof, and the upper portion of the mount 5 is pushed out toward the rear side of the dust box 3. The upper end of the backing sheet 5 is released from a retaining portion of a holder, which will be described later, so that the backing sheet 5 can be moved upward. As described above, the holding portion 6b is configured such that when an extruding spring, which will be described later, abuts on both sides of the upper portion of the backing sheet 5 as compared with a case where the pushing spring abuts on substantially the upper center of the mounting sheet 5. A more even pressing force can be applied to the upper part of the backing sheet 5, so that the upper end of the backing sheet 5 can be more smoothly released from a locking portion of a holder described later. Further, since the holding portion 6b is formed integrally with the front-side partition wall 6a, the size and shape are formed with high accuracy, and one end of the later-described pushing spring can be accurately held, and the cost is advantageous. Configuration. 7 is a holder for holding the backing sheet 5; 7a is a substantially U-shaped engaging portion formed on the holding board 7 for holding the upper end of the backing sheet 5;
Reference numeral 7b denotes a support shaft which rotatably supports the holder 7;
By rotating the holder 7 about the
The mount 5 is released from 7a. 7c urges the locking portion 7a toward the upper end of the mount 5 around the support shaft 7b, and holds the mount 5 by locking the upper end of the mount 5 with the locking portion 7a. Spring for Reference numeral 8 denotes a pushing spring, one end of which is held by the holding portion 6b. As described above, the other end of the pushing spring 8 abuts the upper substantially center of the mount 5, or both sides of the upper. 5 is pushed out toward the rear side of the dust box 3, the mount 5 is inclined to release the upper end of the mount 5 from a retaining portion of a holder described later, and the mount 5 can be moved upward. Configuration. The other end of the pushing spring 8 is formed to have a larger diameter than the winding diameter of the one end, so that the contact area with the mount 5 is increased, and the pushing spring 8 is stably contacted. As another embodiment, as shown in FIGS. 1 and 2, a pushing piece 8 a is provided at the other end of the pushing spring 8,
By contacting the extruded piece 8a with the upper center of the mount 5 or on both upper sides, the other end of the extruding spring 8 is in contact with the upper portion of the mount 5 as described above. It is possible to push the upper part of the backing paper 5 toward the rear side of the dust box 3 in a more stable state, so that the backing paper 5 can be reliably inclined. Reference numeral 9 denotes a moving spring for moving the mount 5 that can be moved upward as described above, upward. The moving spring 9 includes:
It is accommodated in an accommodating portion described later, and one end thereof is in contact with the bottom of the dust box 3, and the other end is in contact with both lower ends of the mount 5. The moving spring 9
Is a state in which the other end of the moving spring 9 is in contact with the lower end sides of the backing sheet 5 so that the backing sheet 5 can be smoothly moved upward, as described above. In a state where the mount 5 is inclined by 8, the mount 5 is configured to protrude above the dust box 3. As another embodiment, as shown in FIGS. 1 and 2, a moving piece 9a having a substantially U-shaped cross section is provided at the other end of the moving spring 9, and the substantially U-shaped moving piece 9a is provided. By storing the lower end of the mount 5 in the section, the mount 5 can be moved upward smoothly through the moving piece 9a. Reference numerals 9b denote groove-shaped receiving portions formed on both sides on the front side of the dust box 3 so as to be continuous with the guides for guiding the mount 5, and for accommodating the moving springs 9. Since the housing portion 9b is formed integrally with the dust box 3, the accuracy of dimensions and position is formed with high accuracy.
The moving spring 9 and / or the moving piece 9a are smoothly slid in the vertical direction. In addition,
The pushing force by the pushing spring 8 is set larger than that by the moving spring 9,
Thereby, while the mount 5 is moved upward by the moving spring 9, the upper end of the mount 5 is preferentially pushed out and released from the locking portion 7a,
Subsequent to the release, the mount 5 is attached to the dust box 3
Is configured to be inclined and move upward. Ten
Is a front cover provided with a suction port 11, and the front cover 10 is attached to the front side of the main body case 6 via a packing 12 for maintaining confidentiality between the suction port 11 and the dust box 3. It is the configuration that was done.

With the above configuration, as shown in FIG. 2, the holding member 7 is released to release the upper end of the mount 5 from the substantially U-shaped engaging portion 7a provided on the holding member 7, The extruding spring 8 pushes the upper end of the backing sheet 5 backward to position the backing sheet 5 so that the backing sheet 5 does not contact the holding member 7, and is provided by the moving spring 9 or at the other end of the moving spring 9. The mount 5 is tilted and moved above the dust box 3 by the moving piece 9a. As a result, the bag-shaped filter 4 together with the mount 5
Are inclined and protruded above the dust box 3, so that a hand can be easily put on the mount 5, and the vacuum cleaner can easily take out the bag-shaped filter 4 from the dust box 3.
