Next, the dust collection chamber lid 36 is rotated downward and closed, and the lid clamp 43 is engaged with the locking step 45. Of course, at this time as well, the storage chamber lid body 61
rotates integrally with the dust collection chamber cover 36. In this way, since the dust collection bag storage section 53 is provided in the dust collection chamber lid 36, the dust collection bag 28 can be easily replaced.

In addition, the fitting convex portion 3 of the support shaft 38 of the dust collection chamber cover body 36
9, since the support shaft 63 of the storage chamber lid 61 is eccentric upward, the positional relationship with the stopper part 65 of the vacuum cleaner main body 1 allows the arms to be moved from the closed state of each lid 36, 61. The rotation angle until the parts 37 and 62 come into contact with the stopper part 65 and are completely opened is larger for the dust collection chamber lid 36 than for the storage chamber lid 61. That is, since the dust collection chamber lid 36 can be opened more widely without lowering the storage chamber lid 61 due to design, the dust collection bag 28 can be replaced more easily.

According to the above configuration, the bearing portion 42 of the cleaner body 1
The support shaft 38 of the dust collection chamber cover 36 is rotatably fitted into the support shaft 38, and the storage chamber cover 61 is fitted onto the bearing portion 40 of the support shaft 38.
Since the support shaft 63 is rotatably fitted, the following effects can be obtained. First, one lid body 36, 61
The lids 36 and 61 can be opened and closed separately without interfering with the rotational opening and closing operation of the other lid 61, 36. In addition, since the support shafts 38 and 63 of both lid bodies 36 and 61 constitute one shaft, not only the support shafts 38 and 63 become compact, but also
The structure of the support shafts 38 and 63 is simplified, and the lid body 3
6, 61 can be easily assembled to the vacuum cleaner main body 1, and therefore the cost can be reduced. Furthermore, compared to the case where both lid bodies are supported by a common support shaft separate from these lid bodies, the number of parts can be reduced and the number of assembly steps can be further reduced. In addition, since the storage chamber cover 61 is pivotally attached to the support shaft 38 located at the rear end of the dust collection chamber cover 36,
The accessory storage chamber 52 covered by the storage chamber lid 61 can be made larger in the dust collection chamber lid 36.

In addition, as shown in FIG. 6, the peripheral portion of the support shaft 63 on the side surface of the arm portion 62 of the storage chamber lid body 61 and the side surface of the arm portion 62 of the support shaft 38 of the dust collection chamber lid body 36 are slid. A knurling 71 is formed radially on either one of the end faces, and the knurling 71 is formed on the other side.
A protrusion 72 may be formed to be removably engaged with.

According to this structure, the storage chamber lid body 61 can be held at any position during the rotation operation, which is convenient.

(Effects of the invention) According to the invention, the dust collection chamber lid for opening and closing the dust collection chamber of the vacuum cleaner body from above is pivotally supported on the vacuum cleaner body by a support shaft formed on the dust collection chamber lid, Accessories of the dust collection chamber lid The storage chamber lid that opens and closes the storage chamber from above has a support shaft formed on the storage chamber lid that fits into a bearing formed on the support shaft of the dust collection chamber lid. Since it is pivoted on this support shaft, the storage chamber lid does not interfere with the opening/closing operation of the dust collection chamber lid, and both lids can be opened separately. In particular, the number of parts is reduced compared to when both lids are supported by a common support shaft that is separate from the lids, and therefore it is easier to assemble the lid to the vacuum cleaner body. .
