FLOOR BRUSH FOR VACUUM CLEANER AND VACUUM CLEANER

摘要

PROBLEM TO BE SOLVED: To solve the problem of breaking down by exceeding a heat resistant temperature of a motive power transmission means by heating of an electric motor without being sufficiently cooled since an air current reduces when the air volume reduces when dust and dirt become full in a cleaner body. SOLUTION: Since a motive power transmission device 27 is oppositely arranged to a suction passage 35, an ambient temperature of the motive power transmission device 27 sufficiently drops. Temperature rise in the motive power transmission device 27 reduces, and heating of the motive power transmission device 27 starts from a lower point, without exceeding the heat resistant temperature of the motive power transmission device 27. Therefore, breakdown can be prevented. Even if heating of an electric motor 26 is received.
