PROBLEM TO BE SOLVED: To secure the tightening force to a lid body of a dishwasher regardless of various assembly errors, and to securely prevent the tightening force to the lid body from becoming excessively large. SOLUTION: In the drawer type dishwasher, a washing tub 2 is supported in a washer body 1 via rails in such a way as can be take out/retracted, and the lid body 3 with packing on the lower face is supported in the washer body 1 in such a way as can be lifted up/down. The lid body 3 is lowered to be closed against a lid opening spring with the cam action of an inclined cam 11 and a cam roller 31 when the washing tub 2 is forced into the washer body. Assuming the drawer type dishwasher with the above structure, the cam roller 31 is supported as can be lifted up/down in a prescribed range by a guide means of the lid body 3. The cam roller 31 is connected to the lid body 3 via a cam spring, and is energized upward by the cam spring. The cam roller 31 is retained at an upper end position of the guide means with the preload of the cam spring. COPYRIGHT: (C)2008,JPO&INPIT
