<p>PURPOSE: To obtain a mounting plate which is easy to be handled and compact by arraying mounting recessed parts on two surfaces of the mounting plate, providing the one mounting recessed part alternately with the other mounting recessed part and making a supply duct provided between the adjacent mounting recessed parts relative with a mounting recessed part of an other row in a perpendicular direction. CONSTITUTION: A second mounting plate surface 4 relative with a first mounting plate surface 3 is arranged in a row with an interval in parallel with each other and a mounting recessed part 2 is provided in parallel with the mounting recessed part 2 of the first mounting plate surface 3 in the same direction. When either one of the first and second mounting plate surfaces 3, 4 is viewed on a plane, one mounting recessed part 2 in a row is located between two mounting recessed parts 2, 2 of the same row except both the ends of the row and is located between the two adjacent mounting recessed parts 2, 2 in an arbitrary row, a supply duct 14 is located between the two adjacent mounting recessed parts 2, 2 in an arbitrary row and the supply duct 14 is provided relatively with one mounting recessed part 2 of an other row in a perpendicular direction.</p> |
