A conventional vacuum cleaner has a dust collection chamber 1 that is opened and closed by a lid 102 at a front portion of a cleaner body case 101.
A blower storage room 104 communicating with the dust collection room 103 and a code reel storage room 105 provided beside the blower storage room 104 are provided at the rear. Then, the electric blower 106 is covered with a sound insulating tube 107 so as to be housed in the blower housing room 104 of the cleaner body case 101, and the cleaner body case 101 has an exhaust port 109 on a rear wall 108, and a rear wall 108 An exhaust passage 111 is formed between the partition wall 110 and the partition wall 110 supporting the rear part of the sound insulation tube 107, and the exhaust flow of the electric blower 106 discharged from the sound insulation tube 107 is once diverted to the upper part in the blower storage room 104. After that, a sound insulation cover body 113 having a bypass air passage 112 leading to the exhaust passage 111 is provided.

[0003] The conventional vacuum cleaner is configured as described above. For example, since the sound insulating cover 113 is provided in the upper part in the blower storage chamber 104, the sound insulating cover 113 and the cleaner main body case 101 are doubled. The wall configuration ensures that the vacuum cleaner is made quieter. In addition, the code reel storage room 105 must secure a space space corresponding to the cord winding length. If the space is too large, the cords become entangled inside the code reel storage room 105 and the cord cannot be pulled out. For this reason, a shielding member that partitions the code reel storage room 105 into an appropriate space has been provided.
