A water-proof structure for an opening of a case of an appliance which includes a sealing member installed in a peripheral groove around a cover wherein the sealing member is compressed between the inner periphery of the opening and the groove when the cover is inserted into the opening. The water-proof structure is adapted to prevent degraded sealing capability or improper installation due to twist of the sealing member in the groove. To achieve this, the sealing member is configured to have a flat contact surface in contact with the bottom of the groove and have a cross section having a width larger than the height. The cross section of the sealing member also has a flat bottom or an inner side to fit the groove bottom that is also flat in a cross section while the outer side has a convex shape so that the whole cross section has a D-shaped form. |
