After mounting the pedestal 32A on the stay 61A, the user holds the stay 61A and rotates it from the removal position to the attachment position. Then, as shown in FIG. 27, the second lever portion 101c of the non-mounting detection lever 101 does not come into contact with the blocking member 102. Then, as shown in FIG. Therefore, the user can properly rotate the stay 61A toward the attachment position. The stay 61</b>A is positioned at a mounting position in contact with the upper surface 25 a of the housing 21 . At this time, the stay 61A is restrained at the mounting position by the lock device 62. As shown in FIG. Also, the dust collection pack 32 has a pedestal 32</b>A connected to the connecting pipe 33 .

After that, the user attaches the opening/closing cover 22 to the housing 21 . At this time, the convex portion 34d of the opening/closing cover 22 does not come into contact with the stay 61A. Therefore, the opening/closing cover 22 can be properly attached to the housing 21 .

On the other hand, if the user forgets to attach a new dust collection pack 32, the pedestal 32A will not be inserted into the stay 61A. Then, as shown in FIGS. 23 and 25, the unmounted detection lever 101 remains at the unmounted position without rotating to the mounted position. That is, the non-mounting detection lever 101 remains at the position where the second lever portion 101 c faces the blocking member 102 . The user holds the stay 61A and rotates it from the removal position to the attachment position. However, the second lever portion 101c of the unmounted detection lever 101 abuts against the blocking member 102 . Therefore, the user cannot rotate the stay 61A toward the attachment position. The user can recognize that the dust collection pack 32 is not attached here.

When the stay 61A is at the removal position, if the user tries to attach the opening/closing cover 22 to the housing 21, the convex portion 34d comes into contact with the stay 61A. Therefore, the opening/closing cover 22 cannot be attached to the housing 21 . The user can also recognize that the dust collection pack 32 is not attached.

[Effect of Second Embodiment]
The upright dust collector 10 of the second embodiment includes, as a non-mounting prevention device 100, a non-mounting detection lever 101 that operates from the non-mounting position to the mounting position by mounting the pedestal 32A to the stay 61A, and a non-mounting detection lever. and a blocking member 102 for blocking the pivotal movement of the stay 61A to the mounting position when the stay 101 is at the non-mounted position. Therefore, when the pedestal 32A is not attached to the stay 61A, the unattached detection lever 101 is at the unattached position. In this state, if the stay 61A is to be rotated from the detachment position to the attachment position, the non-mounting detection lever 101 abuts against the blocking member 102. As shown in FIG. The user can easily recognize that the dust collection pack 32 is not attached.

The unattached detection lever 101 is rotatably supported on the stay 61A by a rotation axis AX4 extending in a direction perpendicular to the stay 61A, and the first lever portion 101b is rotatably mounted on the stay 61A toward the mounting portion of the pedestal 32A, The second lever portion 101c is rotatable outwardly of the stay 61A, and can abut against a blocking member 102 provided on the housing 21. As shown in FIG. Therefore, the mounting operation of the pedestal 32A to the stay 61A moves the second lever portion 101c to a position where it does not come into contact with the blocking member 102, thereby simplifying the structure.

Although the non-mounting detection levers 81 and 101 are rotatably supported in each of the embodiments described above, they are not limited to this configuration, and may be slidably supported, for example.

Further, in each of the above-described embodiments, the dust collector of the present disclosure is applied to an upright dust collector, but the dust collector is not limited to this type. For example, it can be applied to stick-type dust collectors, canister-type dust collectors, backpack-type dust collectors, and the like.
