PURPOSE: To provide a small-sized low-voltage switchboard which can improve the productivity and maintenance and inspection property, without reducing the number of accommodated parts. CONSTITUTION: A truck part 5 is composed, in a box, of a bottom plate 6, a front plate 8, a side plate 8, and a rear plate 9. The truck part 5 is constituted to be pushed in and drawn out freely, with the rollers 10 projected at the edges on both sides of the bottom plate 6 being guided by the guide grooves 4 provided at the opposite inner side faces of the casing 1. Moreover, the side plate 8 and the rear plate 9 are attached capably of standing on their heads to the bottom plate 6, with a hinge 11 as the center of rotation. So, the bottom plate 6, the side plate 8, and the rear plate 9 are developed into plane form by bringing down the side plate 8 and the rear plate 9 outward, in condition that the truck part 5 is pulled out of the casing 1. |
