PURPOSE:To facilitate manufacture, by forming a semi-tubular linking part with the side of an open surface as a center at the upper part of a box shaped body, whose side forms the open surface, and forming a tapered part, which is inclined from the upper part to the lower part at the outer surface thereof. CONSTITUTION:At the upper part of a box shaped body 1, whose side forms an open surface, a semi-tubular linking part 2 is formed with the side of the open surface as a center. A tapered part 3, which is inclined from the upper part to the lower part, is formed at the outer surface thereof. A protruded step part 4 is formed on the side of the open surface. They are contacted when they are assembled and regulate the center of the cabinet of a detector. The periphery 5 of the open surface is formed so that it is slightly lower than the protruded step part 4. Thus a packing having a shape corresponding to the periphery 5 is readily provided. According to this constitution, manufacture can be made easy. |
