PROBLEM TO BE SOLVED: To provide a dust collecting cover which solves the problem that a dust collecting structure causes the deterioration of work efficiency, and effectively improves dust collecting efficiency by using a structure for countermeasure of the problem.;SOLUTION: The dust collecting cover is provided with a cover body 2 which is applied to a cutter body 1 having a rotary blade 11 pivotally fixed to a tip 1a side and allowing a base end side being a grip 12 and is attached to the cutter body 1 in a state that the outer circumference of the rotary blade 11 is partially covered with a circumferential wall 20 thereof, and a dust collecting port mounting part 4 mounted with a dust collecting port 3a of a dust collecting hose 3 which collects the powder dust caused by the cutting of a material 6 to be cut by the rotary blade 11. The dust collecting port mounting part 4 mounts the dust collecting port 3a to allow an opening end 31 to face a position at a more downstream side than a cutting position X along the rotating direction of the rotary blade 11 and at a more upper stream side than the starting end of the circumferential wall 20 of the cover body 2.;COPYRIGHT: (C)2010,JPO&INPIT
