PROBLEM TO BE SOLVED: To provide a power blower in which insulation distance between a commutator shell and a motor frame is easily assured. SOLUTION: A mold 57 which is an insulating member projecting from one end of a comutator shell 56 is made to radially project from the outer periphery of the commutator shell 56. The mold 57 is positioned between a bent part 37 of a motor frame 32 and the outer peripheral surface of the commutator shell 56. An insulation distance (D+E) is easily assured between the outer peripheral surface of the commutator shell 56 and the bent part 37 of the motor frame 32, with no additional separate insulating component. Leakage is prevented surely between the outer peripheral surface of the commutator shell 56 and the bent part 37 of the motor frame 32. COPYRIGHT: (C)2003,JPO
