Zusammenfassung:	The invention provides a nut anti-loosening structure which comprises a nut and a screw rod. A pressing piece is installed between the nut and a connecting piece, the screw rod penetrates through thepressing piece and the connecting piece to be connected with the nut, a plurality of lug pieces are arranged on the peripheral side of the pressing piece, and the lug pieces are obliquely arranged towards the inner side of the pressing piece. The lug pieces are elastically connected with the pressing piece, clamping grooves are formed in the end of the connecting piece, and the lug pieces are arranged in the clamping grooves. Limiting elastic sheets are arranged on the end surface of the pressing sheet, one end of each limiting elastic sheet is tilted and is arranged towards the screwing direction of the nut, a plurality of notches are formed in the end face of the nut, and the limiting elastic pieces are arranged in the notches. The pressing piece for nut anti-loosening is simple in structure, and large-batch man
