Abstract:
1. A vacuum cleaner in which a motor blower including an intake port is built in a cleaner main body including a connection port, comprising: a first dust separation section which is disposed between the connection port and the intake port and which includes a cylindrical air path forming member to separate air and dust flowing toward the intake port through the connection port; a first dust accumulation section which accumulates the dust separated by the first dust separation section; and a second dust separation section which includes a mat-like filter element and which is disposed between the first dust separation section and the motor blower, wherein an axial line of the air path forming member is linear, and the air path forming member includes an introductory port, facing the connection port, into which dust-containing air passed through the connection port is introduced, a derivative port, facing the introductory port, via which the separated dust is derived, and an opening which is covered with a filter and disposed between the introductory port and derivative port and via which a part of the air flowing in the air path forming member toward the derivative port from the introductory port is sucked into the intake port to separate the air from the dust going straight in the air path forming member toward the derivative port from the introductory port with inertia, the diameter of the air path forming member gradually decreasing toward the derivative port from the introductory port, wherein the derivative port and the first dust accumulation section are communicated by a tubular guide section.
