It comprises a member 25 and a spring 26 for urging the indicating member 25 to the suction hole 21 of the cap 23.

Numeral 27 designates a cross-shaped rib formed in the pointing member 25, which fits into the suction hole 21 of the cap 23 to prevent the pointing member 25 from tilting. The air leakage due to the formation of a gap is prevented.

As in the conventional example shown in FIG.
When the convex portion 31 is formed to fit into the suction hole 30 of the cap 29, when the dust collecting chamber 3 becomes a negative pressure and the indicating member 28 slides,
The outside air hits the convex portion 31 and the indicating member 28 moves to the dust collection chamber 3 side. Flows into the dust collecting chamber 3 from the gap without hitting the surface A, and does not slide any further.
As shown in FIG.
Surface B of the pointing member 25,
That is, the area for receiving the outside air increases (the hatched portions in FIGS. 6 and 8), and the slidability of the pointing member 25 improves.

Thus, the indicator 19 is disposed in a state where the tube 24 is connected to the communication hole 9 of the front wall 6 of the dust collecting chamber 3.
Attach the front cover 12. In this state, the air inlet 17 of the front cover 12 corresponds to the suction hole 12 of the indicator 19, and the indicator 19 is inserted into the display window 18 of the front cover 12.
The indicator 19 is sandwiched between the front wall 6 of the dust collecting chamber 3 and the support rib 16 of the front cover 12 while the cylindrical member 20 faces.

During the cleaning, when the dust is filled in the dust collecting bag 2 of the dust collecting chamber 3 and the suction side of the electric blower becomes a negative pressure, the indicating member 25 slides in the cylindrical member 20 to collect the dust. The air moves to the chamber 3 side, and accordingly, outside air flows in from the gap between the indicating member 25 and the suction hole 21 of the cap 23, thereby preventing the electric blower from overheating.

By forming a cross-shaped rib 27 as a regulating member for preventing the inclination of the pointing member 25,
Since the area B exposed to the outside air in a state where the indicating member 25 is slightly slid toward the dust collection chamber 3 is increased, further sliding of the indicating member 25 is facilitated.

According to the above configuration, the indicator 19 is
Since the dust collecting chamber 3 is disposed in the space between the front wall 6 and the front cover 12, the dust collecting capacity of the dust collecting chamber 3 is not reduced, and the indicator 19 is supported by the front cover 12. Therefore, a component for fixing the indicator 19 becomes unnecessary, and the number of components is reduced.

Further, since the display window 18 is formed at the upper corner of the front cover 12, the display window 18 is located closest to the user during cleaning, and the visibility of the user is improved. Further, during cleaning, the indicator 19 can be visually recognized from a position obliquely above and forward of the cleaner main body 1 where the user is located. Therefore, the dead space above the air inlet 5 is used to prevent the front part of the dust collecting chamber 3 of the cleaner main body 1 from being used. Without increasing the size of the indicator
19 can be stored.

In the above embodiment, the display window 18 is formed at the upper corner of the front cover 12;
12 may be formed on the upper surface.
