PURPOSE:To prevent the control part of a handy operating body from being influenced by static electricity by constituting the vacuum cleaner so that static electricity generated in a hose due to friction against a suction air current is collected to a conductive plate through a metallic wire, and subsequently, reaches a power source line through a resistance, and allowed to flow to a ground side of a power source. CONSTITUTION:A hose 2 is provided with a metallic wire 10 for reinforcement, a power source line 11 and a signal transmission line 12 connected to a control part 7 of a handy operating body 3, and a conductive plate 14 for receiving static electricity generated in the hose 2 though the metallic wire 10 and allowing it to escape to a power source side through a resistance 16. As a result, although static electricity is generated in the hose 2 due to friction against a suction air current, this static electricity is collected to the conductive plate 14 through the metallic wire 10. Subsequently, it passes through the resistance 16 and reaches the power source line 11, and flows to a ground side of the power source. Accordingly, it does not occur that the control part 7 of the handy operating body 3, especially, electronic parts, etc., are influenced by static electricity. |
