PROBLEM TO BE SOLVED: To prevent a screw from loosening by fixing a second member of synthetic resin to a first member of metal with a male screw part consisting of a head part and a shaft part. SOLUTION: A plate-shape member 4 having a through hole of an approximately same diameter as a core diameter of a male screw 32a of the male screw part 3 is arranged at a recessed part 12 of the first member 1. Radially extending slits are formed in a circumference edge part of the through hole of the plate-shape member 4. When a shaft part 32 of the male screw part 3 is inserted from a loose through hole 21 of the second member 2 and the male screw 32a is threaded with the female screw 11, the circumference edge part of the plate-shape member 4 is deformed by the male screw 32a and the slits are widened. Thus, as the plate-shape member 4 is press-contacted to a helical groove of the male screw 32a, the screw is prevented from loosening. COPYRIGHT: (C)2007,JPO&INPIT
