When the height of the base table 50 is adjusted, the height of the upper surface of the peripheral edge of the opening 50c of the base table 50 is caused by the fact that the base table 50 bends and the height differs between the front and rear of the opening 50c. And the height of the rotary blade 51 can be prevented from differing between the front portion and the rear portion, and the difference between the height of the rotary blade 51 and the height of the upper surface of the opening 50c of the base table 50 is the same in the front and rear. I was able to. As a result, vegetables such as cabbage rotating on the upper side of the recess 50a of the base table 50 can be chopped so as to always have the same width.

  Moreover, this vegetable cutting machine 10 adjusted the height position of the rotary blade 51 by moving the 1st rotating shaft 21 to an up-down direction, without adjusting the height of the base table 50 to the base 11. Is. For this reason, even if the base table 50 is frequently detached (for example, every day of use) to periodically clean the base table 50, the height of the upper surface of the concave portion 50a of the base table 50 and the height of the rotary blade 51 are reduced. The difference can always be constant before and after the base table 50 is attached to and detached from the base 11. Thus, every time the base table 50 is attached to or detached from the base 11, it is not necessary to adjust the difference between the height of the upper surface of the recess 50 a of the base table 50 and the height of the rotary blade 51. The vegetable cutting machine 10 can be easily easily disassembled and cleaned without worrying about the troublesome adjustment of the difference between the height of the upper surface of the recess 50a and the height of the rotary blade 51.
