A secondary battery (not shown). Further, as shown in FIG. 3, a packing 10 is disposed on the contact surface of the cleaner main body 1 with the dust collecting case 2 so as to be inclined (preferably approximately 45 degrees) with respect to the floor surface.
[0018]
Further, the dust collecting case 2 is provided at a position where the centrifugal separation chamber 11 and the electric blower 19 communicate with each other, and is inclined (preferably approximately 45 degrees) with respect to the floor surface. It has an inlet 12 and a filter 17 provided on the way from the centrifugal separation chamber 11 to the inlet 12. The air inlet 12 contacts the packing 10 to form an airtight surface when the dust collecting case 2 is set in the cleaner body 1, and as a result, the airtight surface is inclined with respect to the floor surface. It has become.
[0019]
Further, the lid body 13 has a rear portion pivotally supported in the vicinity of the suction port 12 with respect to the cleaner body 1, and covers the dust collection case 2 during the closing operation. The lid body 13 is provided so as to be openable and closable with the buckle locking part 20 with respect to the cleaner body 1. The lid body 13 is provided with a pressing portion 14 at a position corresponding to the upper portion of the outer periphery of the intake port 12 for pressing the upper portion of the outer peripheral portion of the intake port 12 in the direction of the airtight surface during the closing operation. The pressing portion 14 is preferably provided on the lid body 13 in terms of handling, but is not necessarily limited to this. For example, a projection is provided on the outer periphery of the intake port 12 and the projection is provided when the lid body 13 is closed.
