上下両端縁を挿抜・保持できるように構成されている。[Prior Art] As shown in FIG. 4, the Sheelf printed board guide structure, which has been widely used in the past, has sliding grooves 3a of a fixed size formed in the longitudinal direction on one surface of a square column for sliding both edges of the printed board. Then, on the mounting surface on the opposite side, a guide member 3 made of a synthetic resin material with a hanging protrusion having a retaining shape, or a sliding groove 3a of a certain size made of a thin metal plate is formed in the same manner as above. A plurality of guide members formed in the longitudinal direction and coated with metal, for example, galvanized on the front surface, are attached to the upper and lower inner surfaces of a shelf 2 formed into a box shape into which a plurality of printed board units 1 can be attached. By arranging the mounting bits parallel to the mounting direction, the sliding grooves 3a are guided so that the upper and lower edges of the printed board unit 1 can be inserted and removed and held.

振動が生じている。Problems to be Solved by the Invention The problem with the conventional printed board guide structure described above is that the guide member 3 is arranged in the shelf 2 so that the sliding grooves 3a that guide the insertion and removal of the printed board unit 1 are opposed to each other. Since it is engaged in parallel to the upper and lower inner surfaces, a difference occurs in the dimension between the bottom surfaces of the sliding grooves 3a of the opposing guide members 3 due to the dimensional accuracy of the guide member 3 itself and the accuracy of the shield 2, etc., and as a result, It is difficult to insert the printed board, or the inserted printed board is vibrating due to external force.

恐れが発生するという問題が生じている。In addition, the number of guide members 3 required corresponds to the number of printed board units 1 held by the shelf 2, which increases the number of parts and assembly man-hours, and also increases friction when inserting and removing the printed board units 1. In the guide member 3 molded from synthetic resin, abrasion and friction debris occur, and in the guide member 3 molded from a thin metal plate, the plating on the sliding groove 3a may peel off and the plated metal debris may reduce the reliability of the equipment. There is a problem of doing so.
