PURPOSE: To spread wiring space and to improve execution property by bending both side edges of the upper surface of a substrate downward and forming the both side edges, providing a through hole on the side surface of an inner machine mounting rail, providing a cut-out at the edge part of the both side edges of the substrate, and sealing the through hole and the cut-out whole opposing them, and mounting the substrate on the inner machine mounting rail. CONSTITUTION: Both side edges of a machine base 1 are bent downward and a cut-out 4 is formed at the lower edge. A plurality of through holes 2a are provided at the mounting position of the substrate 1 on the side surface of an inner machine mounting rail 2. Screws 3, 3 for sealing the substrate 1 are tentatively locked to the through holes 2a, 2a and the substrate 1 is made perpendicular to the longitudinal direction of the inner machine mounting rails 2, 2 and cut-outs 4, 4 on the surface of the inner machine mounting rails 2, 2 are allowed to oppose the tentatively locked screws 3, 3. The substrate 1 is slid until the screws 3, 3 reach terminal parts 4a, 4a of the cut- outs 4, 4 and the screws 3, 3 are actually locked, thus effectively using space, miniaturizing the substrate, and reducing the weight of a power distribution panel. |
