めである。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described in detail with respect to a threaded connection between a tube and a male screw rod in a wall connection according to the present invention.
Both sides of a straight metal pipe with a length of about 16 mm and a diameter of 11 mm
In a tubular body having a female screw provided in the narrowed portion, a convex portion projecting about 0.3 to 0.5 mm is formed at the bottom of the groove of the female screw by using a press from the outside of the narrowed portion. In advance, the female screw is threadedly connected to a metal rod having a diameter of 7 mm using a male screw rod which is threaded at a pitch of about 1.4 mm. This connection was achieved by applying a screwing holding portion from the distal end of the male screw rod to the middle thereof to generate a strong screw input. When the male screw rod thus screwed and connected is tightened with the nuts for tightening and locking through the frame, the male screw rod and the locking nut do not rotate together, and the desired function is achieved. Achieved. This is because the screwing torque of the male screw rod which is screwed against the deformed portion of the female screw of the tube is considerably larger than the necessary tightening torque of the tightening tool.
