PURPOSE:To prevent a puddle of rain water or the like from being formed by providing chamfers on the peripheral section of a pan, and fixing and holding the pan with pressing members via chamfers at positions lower than the upper face of the pan. CONSTITUTION:End sections of a pan 2 are inserted into coupling recesses formed with pressing members 3 and holding members 6 and hermetically held via rubber packings 7. End sections of rubber packings 7 on chamfers 8 are located above the upper face of the pan 2, and upper faces of pressing members 3 are located below the end sections of rubber packings 7. The peripheral section of the pan 2 is located below the upper face of the pan 2, and no recess forming a puddle is generated. |
