To solve a problem that positions of plates are not regulated in a direction that the plates approach mutually at a part caught by a hook despite the positions regulated in a bulging direction in the case of a door panel for a dishwasher equipped with a hook catching structure as well as a screw fastening structure for a frame part to prevent the door panel from getting loose or bulging in a direction to separate the plates.

The door panel is constituted by superposing at least two inner and outer panels 4, 5 used for an upper door 2 and a lower door 3 of a main body 1 of the dishwasher. A hook part 6 comprises a catching part 8 at the end and an arm part 7 provided with a rib regulated in a direction of a thickness on the base side from the catching part 8. The hook part 6 is placed inside the panels 4, 5 to be superposed, and a panel mounting plate 10 for catching and fixing the hook part 6 is placed on a surface opposing to the hook part 6. As a result, the position of the panel in terms of the direction of the thickness is regulated in the bulging and crushing directions.
