The screw part includes: a plate-like washer part 10 where a shaft part of the screw is penetrated to abut on the lower end of the head of the screw; a plurality of movable pieces 20 formed radially on the outer peripheral part of the washer part 10; and a hinge part 30 formed at the boundary between the washer part 20 and the movable pieces 20. The plurality of movable pieces 20 are put in the closed state by the deformation of the hinge part 30 to thereby cover the head of the screw. COPYRIGHT: (C)2011,JPO&INPIT
