Since the drive shaft 10 and the through hole 16 are engaged with each other through the splines 12 and 18, and a certain degree of clearance is structurally required, eccentricity and inclination cannot be completely prevented. .

It is necessary to tighten the nut 20 to fix the dehydration basket 14. Therefore, the nut 20 must be rotated when the basket 14 is attached or detached, which makes the operation troublesome.

Since the nut 20 is located at the bottom of the dehydrating basket 14, if the dust collecting bag (not shown) is set in the basket 14, the nut 20 cannot be tightened or removed. Therefore, when attaching / detaching the dehydration basket 14 to / from the drive shaft 10, it is necessary to remove the dust collecting bag from the dehydration basket 14, which is troublesome. Also, there is a possibility of forgetting that the garbage collection bag has been removed and throwing garbage into the dehydration basket 14 without setting the garbage collection bag in the dehydration basket 14. In this case, the nut 20 cannot be turned unless the dust is manually removed from the basket 14.

Contamination on the upper end of the drive shaft 10 is likely to collect inside the cover nut 20, which is unsanitary.

When the dehydration basket 14 is detached and then connected to the drive shaft 10 again, if dust or the like remains on the drive shaft 10, the splines 12 and 18 may be trapped in the dust or the like. It becomes an obstacle factor of the combination.
