Abstract: A parts storage box includes a box cover, a box body and a plurality of storage compartments. Each of the storage compartments includes a bottom portion and side wall portions which are connected to one another. The box cover is arranged on the box body, and an accommodation space formed between the box cover and the box body is used for placing the plurality of storage compartments. Limiting members used for fixing the storage compartments are arranged on the box cover or the box body. Through the arrangement of the limiting members for limiting the storage compartments on the box body or the box cover, the present disclosure can reduce the incidence of shaking in the storage compartments, thereby reducing the circumstances where parts inside a box are all tangled up due to the misoperation of a user.
