VACUUM CLEANER AND AIR CHANNEL FORMING BODY THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an air channel forming body capable of preventing dust from being sucked from an insertion opening.SOLUTION: Each of a hand operation part 27 and an upstream extension pipe part 31 has a communication opening 66 to communicate with insertion openings 51 and 51 and an air channel 24. Each of the hand operation part 27 and the upstream extension pipe part 31 has a clamp 54 partially protruding from the communication opening 66 into the air channel 24 for clamping a downstream extension pipe part 32 and a connection pipe 37 inserted into the hand operation part 27 and the upstream extension pipe part 31. Each of the hand operation part 27 and the upstream extension pipe part 31 has a sealing part 61 provided on the clamp 54 which seals a gap between the communication opening 66 and the clamp 54 in a state where a part of the clamp 54 protrudes from the communication opening 66 into the air channel 24.
