Abstract
A power cutter is disclosed whose dust suction-discharge fan is driven to rotate at a high speed to thereby attain sufficient dust suction-discharge performance, and which can be constructed relatively compactly in size as a whole at a reduced cost. The power cutter includes two rotating operative components (30, 50) driven by a prime mover (5) and a centrifugal clutch (10) operatively connected to the output shaft (7) of the prime mover (5) for rotationally driving the two rotating operative components (30, 50). The centrifugal clutch (10) includes a clutch drum (11) composed integrally of a small diameter pulley portion (21) and a large diameter pulley portion (22). Belt-type drive trains (15A, 16A and 17A, 18A) transmit the rotational drive force to the rotating operative components (30, 50), respectively.
