A dust-collecting device includes a cylindrical casing and an insertion part. The casing includes an introduction port introducing dust-containing air. The insertion part is positioned inside the casing to allow a swirling flow of the dust-containing air to be formed between the insertion part and the casing. The insertion part includes a cylindrical side surface part spaced away from and facing the casing and a projection part. The projection part includes, in a side of the first dust-collecting part, a projection surface projecting outward from the side surface part. The projection surface includes plural straightening parts and a connection part. The straightening parts are formed spirally toward the side of the first dust-collecting part, from upstream to downstream sides of the swirling flow. The connection part connects a downstream end side of one of the straightening parts and an upstream end side of another one of the straightening parts.

Dust-collecting device and vacuum cleaner

A vacuum cleaner includes a main body portion, a secondary battery, an electric blower, a handle and a conductive member. The secondary battery is disposed in the main body portion. The electric blower operates by electric power supply from the secondary battery. The handle is one which a user contacts when the vacuum cleaner is used. At least a part of the conductive member is disposed at the handle and conducts static electricity generated due to operation of the electric blower.

Electrical equipment using battery as power supply and vacuum cleaner

A vacuum cleaner is provided with a cleaner main body having an electric blower and a handle. The handle is shaped such that a gravity center position of the cleaner main body remains substantially unchanged in a state in which any one region is gripped.
