PROBLEM TO BE SOLVED: To provide a pipe shelf which is expansible not only in a width direction but also in a depth direction in order to effectively use the space of an arrangement place. SOLUTION: A shelf portion is constituted by arranging: a plurality of long outer pipes 1 for the shelf, which are arranged in parallel; a plurality of long inner pipes 2 for the shelf, the number of which is the same as the pipes and which are inscribed in the pipes so as to be slid; short outer pipes 3 for the shelf, which are orthogonally to both ends of the pipes; and short inner pipes 4 for the shelf, which are inscribed in the pipes so as to be slid. Legs 9 are raised at the four corners of the shelf portion, and the lower parts of the legs 9 are connected to short outer pipes 7 for holding the legs and short inner pipes 8 for holding the legs, which are inscribed in the pipes so as to be slid. The intersections of the respective pipes are connected by using connection components A, B, C (5, 6, 10), thereby enabling the shelf portion to be expansible in the width direction and the depth direction by the slide of the respective outer and inner pipes.
