The invention discloses a linear sliding rail and a dustproof piece thereof. The dustproof piece comprises a supporting strip and at least one elastic rib integrally formed on the supporting strip. The elastic modulus of the supporting strip is 2000%-100000% of the elastic modulus of at least one elastic rib. When at least one elastic rib abuts against the outer surface of a track to define a dustproof area, the at least one elastic rib comprises an inner side face located in the dustproof area and an outer side face located on the opposite side of the inner side face. In a cross section, an inner configuration angle is formed between the inner side surface and a normal vector of the outer surface, and an outer configuration angle is formed between the outer side surface and the normal vector. The sum of the inner configuration angle and the outer configuration angle is 30-40 degrees, and the inner configuration angle is 400-600% of the outer configuration angle. Therefore, the configuration of at least one e
