In other words, the axis 215 and the rotation center line of the wheel 12 of the cleaner body 7 mounted on the pedestal 41 are disposed substantially in parallel. Therefore, when the reduction mechanism 44 falls, the cleaner body 7 is in the use position.

  • the speed reduction mechanism 44 is moved ( fallen). By this movement, the elastic member 213 stores energy for causing the speed reduction mechanism 44.
  • the elastic member 213 is, for example, a torsion spring.
  • the elastic member 213 does not prevent the cleaner body 7 mounted on the pedestal 41 in the storage posture from falling down due to the application of external force, and causes the speed reduction mechanism 44 to the standby position after the cleaner body 7 is separated from the station 2.
  • the charging terminal 46 of the station 2 can be connected to the cleaner body 7 in the stored state, and the connection with the cleaner body 7 is released when the cleaner body 7 is turned to the use posture. For this reason, the terminal cover 219 of the charging terminal 46 has a slit 219a facing upward of the station 2 and a slit 219b facing in the direction in which the vacuum cleaner 3 is detached from the station 2, that is, the front direction of the station 2. ( Figure 24).
  • the charging terminal 46 is connected to the charging electrode 19 of the cleaner body 7 inserted into the slits 219a and 219b.
  • the vacuum cleaner 3 can be used by raising the vacuum cleaner main body 7 from the pedestal 41 to the upper side of the station 2 and lowering it to the use posture on the surface to be cleaned (floor surface). However, it is less convenient to lift and move the cleaner body 7 when using the vacuum cleaner 3.

That is, when the user operates the vacuum cleaner body 7 so that the user can move over the fall fulcrum 202, the cleaner body 7 can use the storage posture while changing the direction with the fall fulcrum 202 as a fulcrum.
  • the speed reduction mechanism 44 reduces the moving speed of the cleaner body 7 falling down to reduce the impact on the cleaner body 7. Also, when the auxiliary wheel 12b of the vacuum cleaner 3 is grounded, the suspension mechanism 56 (FIG. 4) provided between the auxiliary wheel 12b and the handle 55 cushions the grounding to the cleaner body 7 .
