The cylinder 15 of this indicator 14 is provided with an indicator piston 17 energized by a spring (not shown).
This display piston 17 is moved by changes in wind pressure in the ventilation passage 16.

Further, the amount of movement of the display piston 17 is confirmed through a viewing window 18 formed on the top surface of the main body case 1, so that clogging of the filter can be detected.

Furthermore, a clamp locking hole 20 is formed in the front surface of this protrusion 9.

Further, a locking portion 19 is formed at the lower front end of the main body case 1.

Next, reference numeral 21 denotes a dust collection case, and a dust collection part 22 is opened at the rear surface of the surface connected to the main body case 1.

Further, the locking portion 19 is located at the lower rear surface of the dust collecting case 21.
A fitting part 23 is formed on the upper part of the dust collection case 21 to fit the protrusion 9 of the main body case 1, and a fitting surface 24 is formed opening at the rear surface. Joint part 24
The inner surface facing the bottom surface of the protrusion 9 is formed into a horizontal plane that is substantially parallel to the bottom surface of the protrusion 9 .

Further, the upper surface of the dust collection case 21 is formed with a groove portion into which the knob 13 of the main body switch 12 of the main body case 1 is inserted.

Furthermore, a clamp body 25 is provided at the front of the fitting portion 24 of the dust collecting case 21 and is detachably fitted into the clamp locking hole 20 of the main body case 1.

Furthermore, a hose connection port 26 communicating with the dust collection section 22 is opened in the front surface of the dust collection case 21.

Further, 27 is a filter, which is the dust collecting part 2 of the dust collecting case 21.
