Abstract: The present invention provides an article pushing device for pushing an array of hanging articles along a hook bar by the action of self-restoring force of a compression spring body which can be elastically compressed with no space loss and be easily fitted on a hook bar without previously taking off the articles. The device comprises a zigzag leaf-spring body having a series of sharp alternate turns forming peaks and bottoms, which spring body can be contracted with substantially no space between neighboring parallel leaf-portions and has a series of notches (sliding holes with an open slit) made in peaks thereof for externally fitting onto the hook bar. The zigzag leaf-spring body is provided with a pushing portion at its front end and a holding member at its rear end.
