To provide a spinner devised so that an adhesive liquid for sticking two sheet of plate materials together may not be moved round to the upper face.

IN the spinner having a chuck 2, which is placed in a housing 3, for fixing a material to be coated on the top end of a rotary shaft 1 and extending a coating liquid by a centrifugal force, which is made to drop, on the surface of the material to be coated by rotating the plate-shaped material to be coated placed and fixed to the chuck 2 in the housing, a cover 4 is arranged on the housing 3 in such a way that the cover 4 is positioned above only the peripheral area of the material to be coated at narrow intervals. Since the adhesive liquid is not allowed to move onto the upper face of the product when the two sheets of plate materials are stuck together by using such a spinner, defective products are not produced.
