PROBLEM TO BE SOLVED: To provide a structure of a connecting part for a knock down shelf frame capable of easily and freely conducting assembling, expanding, changing a structure or the like, and comparatively easily managing and carrying components. SOLUTION: Frames 2, 3 forming a shelf frame are formed by bending a metallic plate into the shape of a partially cutout square in a cross-section in the direction perpendicular to the longitudinal direction. A connecting member 1 is composed of a cubic or approximately cubic first block, and a second block 5 connected to one of upper and lower, left and right, and front and rear faces of the first block by means of a connecting bolt 6. The second block 5 has a frame connecting engagement part 5c capable of connecting the frames 2, 3 and the second block 5 by being engaged with the frames 2, 3, on its peripheral face in the direction perpendicular to the connecting direction to the first block 4, and the second block 5 and the frames 2, 3 are provided with threaded holes 5d, 2a, 3a to be screwed.
