Résumé dans la langue de publication A wiper apparatus which sandwiches a strip plate 2 between upper and lower wiper rolls 3 and 4 to squeeze out a rolling oil adhering to the strip plate 2, wherein backup rolls 5, 6 for reinforcing the wiper rolls 3, 4 each have a single sleeve 14 rotatably supported by two bearings 13 on a roll shaft, and the bearings 13 on the upper and lower backup rolls 5 and 6 are disposed on the roll shafts with a shorter span than the barrel length of the sleeve, and in point symmetry. Thus, a contact linear pressure distribution of the wiper rolls 3, 4 on the strip plate 2 can be made uniform.
