Abstract

PROBLEM TO BE SOLVED: To prevent dust from overflowing from the port frame opening hole of a dust collecting bag at the time of taking out the dust collecting bag from a dust collecting chamber. SOLUTION: Since a movable plate 12 is freely slidably provided on a port frame 8 provided with an opening hole 9 and the movable plate 12 is energized outwards by an energizing body 11, when this dust collecting bag 7 is mounted to the dust collecting chamber, the outward projection part of the movable plate 12 is abutted to a part of the dust collecting chamber, the port frame 8 is slid against the energizing body 11 and the opening hole 9 of the port frame 8 is opened. Also, when the dust collecting bag 7 is detached from the dust collecting chamber, the movable plate 12 slides the port frame 8 by the force of the energizing body 11 and closes the port frame opening hole 9.
