At the end of the handle portion 132 on the dust discharge lid 131 side, a locking means 133 for holding the dust discharge lid 131 in the dust container 130 is provided. The locking means 133 includes a button part 133 a for the user to press and an engaging claw part 133 b that engages with an engaging hole part 131 b formed in the upper part of the dust discharge lid 131. When the button part 133a is pushed to the handle part 132 side (the front side of the cleaner body 201), the engagement claw part 133b moves downward, and the engagement state with the engagement hole part 131b is released. As a result, the dust discharge lid 131 opens the opening of the dust container 130 with the rotation shaft 134 as a rotation fulcrum, and discharges the dust in the dust container 130. The filter 131a is formed in a fold shape, and is configured so that the fold line is in the vertical direction. For this reason, when the dust collection case 106 is attached to the dust collection unit 104, the spirally wound wire 112b of the first dust removal means 112 enters the fold of the fold-fold filter 131a. When the electric cord is pulled out from the cord reel 107 in this state, the rotational force is transmitted to the first dust removing means 112 via each gear as described above, and the wire 112b rotates and repels the filter 131a. Thereby, dust removal of the filter 131a is performed.

  Returning to FIG. 5, the second dust removing means 120 is provided on the dust collecting portion 104 side (back side) of the dust collecting lid 105. The second dust removing means 120 is rotatably provided with the rotation shaft 120a as a rotation fulcrum.

1 is a longitudinal sectional view of the cleaner body 201, FIG. 2 is a partially enlarged view of FIG. 1, and FIG. 3 is an exploded perspective view for explaining the operation of the first and second dust removing means. The second dust removing means 120 is formed with a striking portion 120b that strikes from above the filter 131a through the dust collecting case 106 to give vibration, and a receiving portion 120c. A rotating body 121 is provided on the side of the first dust removing means 112 opposite to the side where the dust removing gear 111 is provided, and the rotating body 121 is provided with a cam 121a. A transmission unit 122 that transmits the rotational force of the rotating body 121 to the second dust removing unit 120 is provided. The transmission means 122 is provided with a rotation shaft 122a that supports the transmission means 122. The rotation shaft 122a can be turned around the rotation shaft 122a. Further, the transmission means 122 is provided with a cam receiving portion 122b that comes into contact with the cam 121a and a protruding portion 122c that comes into contact with the receiving portion 120c of the second dust removing means.

In the above configuration, when the electric cord is pulled out from the cord reel 107, the rotational force is transmitted to the first dust removing means 112 via the gears described above, and the first dust removing means 112 rotates. This rotational force is transmitted to the rotating body 121, and the rotating body 121 rotates together with the cam 121a. When the cam 121a comes into contact with the cam receiving portion 122b, the cam receiving portion 122b is inclined so as to be retracted with the rotating shaft 122a as a fulcrum as shown in FIG. In this state, since the protrusion 122c is in contact with the receiving portion 120c of the second dust removing means 120, the striking portion 120b of the second dust removing means 120 moves upward with the rotating shaft 120a as a rotation fulcrum. When the rotating body 121 further rotates, as shown in FIG. 2A, the cam 121a is separated from the cam receiving portion 122b, the inclination of the transmitting means 122 is eliminated, and at the same time, the protruding portion 122c is the receiving portion 120c of the second dust removing means 120. Get away from. And the striking part 120b of the 2nd dust removal means 120 contacts the filter 131a. By repeating this operation, the striking part 120b strikes the filter 131a to give vibration and removes the dust from the filter 131a. The striking part 120d may strike the filter frame 131c to apply vibration to remove dust from the filter 131a.
