Abstract

In this dishwasher 1 , a spring 33 utilized for moving a door 7 up and down is accommodated within a column 6 of a washer body 2 , so as to be confined within the column 6 , whereby the appearance becomes better while the spring 33 is protected against water. Also, the space between left and right columns 6, 6 can be utilized as a washing chamber 3 , thus making it possible to expand the washing chamber 3 , whereby the dishwasher can be made smaller while keeping the capacity of the washing chamber 3.
