<P>PROBLEM TO BE SOLVED: To provide a resin nut that can achieve both of adjustment of a full length and fine adjustment of tightening torque or the like (removal force and breakdown torque), and a coupling structure of a fuel tank with a heat insulator. <P>SOLUTION: A pilot hole 33 with which a tapping screw 10 is screwed, and a screw insertion hole 34 specified to be larger in diameter than the pilot hole 33 and in which a tip 10A of the tapping screw 10 protruding from the pilot hole 33 is inserted are formed. A level difference surface 35 between the pilot hole 33 and the screw insertion hole 34 is formed on a tapered surface becoming larger in diameter toward the screw insertion hole 34. <P>COPYRIGHT: (C)2013,JPO&INPIT |
