  • a lever 20 is provided at the outer periphery of the boss portion 18 so as to be able to freely advance and retreat, and is provided with a drive shaft 20 at right angles to the shaft hole 19 at right angles. Engage the step 16 of 15 to prevent the rotary cleaning tool 17 from coming off from the same drive shaft 15.
  • the lever 20 is urged in the forward direction by a spring 21 and has an inclined surface 22 at its tip.
  • the direction of inclination of the inclined surface 22 is set such that the lever 20 is retracted by the pressing force of the tip of the drive shaft 15.
  • the rotation of the motor 14 is transmitted from the polygonal portion of the drive shaft 15 to the rotary cleaning tool 17 through the same polygonal glaze hole 19. .
  • the attachment of the rotary cleaning tool 17 to the drive shaft 15 is only required to insert the shaft hole 19 into the drive shaft 15. sand That is, when the shaft hole 19 is fitted into the drive shaft 15 and the rotary cleaning tool 17 is pressed, first, the inclined surface 22 hits the tip of the drive shaft 15, and the lever 20 is pushed. Treatment once. Then, at the position corresponding to the step 16, the lever 20 moves forward by the action of the spring 21, and the tip of the lever 20 engages with the step 16. It is.
