PURPOSE:To provide the titled filtering type dust collector made stable in a sucking air amount through the enhancement of dust removing effect, in suction type dust collection by a V-shaped multi-pleat unwoven fabric, by striking and vibrating the surface of filter cloth by the elastic dust removing element of an arm swung by a link mechanism. CONSTITUTION:Air sucked by rotating a turbo fan 3 enters a machine and passes the filtering surface of a V-shaped multi-pleat unwoven fabric 17 to be exhausted from an emitting port 5. An elastic dust removing element 10 such as a spring is provided to a dust removing arm 11 awung around a fulcrum point 15 by the cam 14 and the arm 12 of a motor 13 and a large number of pleats of the filter cloth 17 are flipped and vibrated to shake off dust adhered to the filtering surface. By this method, dust removing effect becomes good and a sucked air amount is made stable simply.
