A part-stocking/extracting device comprises a rack composed of a coaxial stack of a plurality of cylindrical bodies, each having at least one part-containing section provided with compartments that are defined by partitioning the peripheral portion of the part-containing section and each having an open end at the peripheral portion. The cylindrical bodies are independently turned. The part-stocking/extracting device further comprises a first part-grasping means disposed oppositely to the peripheral portions of the rack and at least one part-stocking/extracting means for transferring a part grasped by the first part-grasping means to a specified part-containing section and stocking the part therein. The device further comprises a second part-grasping means disposed oppositely to the peripheral portions and at least one means for grasping and extracting a part contained in the specified part-containing section and transferring the part to a specified position. Each cylindrical body and each part-grasping means can move relatively with each other along the peripheral portions of the rack.
