PROBLEM TO BE SOLVED: To solve the following problems: assemblability is insufficient because a fall or the like occurs between supply of two components and screwing by looseness occurring when having placed the components on a turntable or a conveyor during assembly of the two components; and, when the looseness during the assembly occurs, the centers of the two components which have been in line with each other during the component supply are shifted, and the thread beginnings of screws ride on each other during the screwing without serving as a guide, so that there is possibility that the two components are obliquely screwed.SOLUTION: In this screwing structure between a male screw member and a female screw member, at least one screw member of the male screw member and the female screw member is formed with a press-in part wherein one of the screw members is pressed into the other of the screw members, and the press-in part is formed in a part before the screwing of the screw members is started. |
