  • the dust collecting fan 9 When the operator operates the switch on the operation panel 5 to drive the motor 6, the dust collecting fan 9 is rotated by the driving force of the motor 6. The airflow generated by the dust collecting fan 9 is taken into the dust case 3 from the intake port 3a. The air flow passes through the filter member 40 and is taken into the fan cover 20 from the intake ports 2d and 21. The airflow is sucked into the inside of the dust collecting fan 9 and discharged to the outside, guided by the fan cover 20, and exits rearward from a vent of the fan guide 10 (not shown). The airflow is finally exhausted from the exhaust port 2e to the outside of the housing 2. Dust that has entered from the intake port 3a together with the air flow is collected by the filter member 40 and collects inside the dust case 3 and outside the filter member 40. The presence of the seal member 30 prevents airflow from circulating inside and outside the fan cover 20. As a result, the suction efficiency from the intake port 3a is enhanced.
  • the seal member 30 has a smaller diameter than the fan cover 20. Therefore, the seal member 30 can be made smaller and lighter than a large seal member that covers up to the outer peripheral surface of the fan cover 20. Therefore, it is possible to suppress an increase in size, weight, and manufacturing cost of the entire product.
  • the seal member 30 not only improves the suction force by the seal, but also functions as a vibration-proof member. Therefore, as compared with the case where the anti-vibration member is provided separately from the seal member, the number of parts can be reduced, and the suction force and the anti-vibration property can be improved with a simple structure. Further, since the fan motor unit including the motor 6, the dust collecting fan 9, the fan guide 10 and the fan cover 20 is supported by the housing 2 only by the elastic body 7 made of an elastic body such as rubber and the seal member 30, the fan motor The vibration generated in the unit is suppressed from being transmitted to the housing 2.
  • the first seal portion 33 is pressed against the rear surface of the flange portion 2i, and the inclined surface 23 is pressed against the second seal portion 34 by the forward pressing force applied from the fan cover 20 to the seal member 30. That is, the seal member 30 is sandwiched between the fan cover 20 and the flange portion 2i from the front-rear direction.
  • the flange portion 2i is fitted into the groove portion 35, and the sealing member 30 is sandwiched between the left housing 2f and the right housing 2g from the left-right direction.
  • the second rotation regulating unit 32 regulates the relative rotation of the seal member 30 with respect to the fan cover 20 by engaging with the grid unit 22.
  • the grid portion 22 prevents the entry of fingers and foreign matter from the intake port 21. Therefore, in order to regulate the relative rotation of the seal member 30 with respect to the fan cover 20, it is not necessary to separately add a configuration for preventing rotation on the fan cover 20 side. Therefore, the complexity of the configuration can be suppressed.
