Abstract

PROBLEM TO BE SOLVED: To provide a quiet cleaner capable reducing a main body. SOLUTION: Discharged air discharged from a motor chamber is passed through a discharge grating 19 and made to flow to a first passage body 20 and the direction of a flow is changed almost at a right angle along a discharge passage 23. The direction-changed discharged air is made to flow into a lower passage 25 along a first discharge bypass part 28 provided in the first passage body 20, then direction changed again along a second discharge bypass part 29, passed through an upper passage 27 and discharged from a discharge port 26 formed at the upper part of a cleaner main body 11. Thus, since the discharged air discharged from the motor chamber is discharged to the outside of the cleaner main body 11 after being passed through the discharge passage long, sound obstructive to ears generated at a motor 16 is absorbed.
