A portable powered cutter has an operation tube (10), a transmission shaft (40) inserted in the operation tube (10), and a rotating blade (31) supported through a blade holder (30) connected to the head section of the operation tube (10). Rotation output from a power source is transmitted to the rotating blade (31) through the transmission shaft (40) to rotate the blade. The blade holder (30) swings against predetermined resistance about a lateral axis (14) perpendicular, in a plan view, to the axis of the operation tube (10). The transmission shaft (40) has flexibility in at least a portion from the head section of the operation tube (10) to the blade holder (30). That portion of the transmission shaft (40) having flexibility is surrounded by a bellows tube (100). |
