Claims

[Scope of utility model registration request]

It has a main body case containing an electric blower and a dust collection case containing a dust collection filter, and an annular backing attached to the filter frame of the dust collection filter is connected to a seal wall having an air intake port of the main body case. The electric motor has a structure in which a bypass air passage is formed between the backing and a recess provided in the seal wall across a portion where the backing contacts, and communicates the air intake with outside air. In the blower, a fitting portion of the annular backing fitted to the filter frame and a lip portion that is integral with the fitting portion and contacts the seal wall are connected to a portion of the bypass air path by a rib that is integral with these. A vacuum cleaner characterized in that:
