<p>PROBLEM TO BE SOLVED: To provide a fitting structure in which a joint member is easily fixed to a base member and the joint member is hardly pulled out of the base member.SOLUTION: This invention relates to a fitting structure for fixing a joint body 6 to a base member 5 through a joint member 4. A concave groove 50 of the base member 5 has a narrow width part 51 at an opening side and a width wide part 52 at a groove bottom side. The joint member 4 comprises a threaded part 40, angle defining part 41, fixing member 42, pressing part 43 and nut part 44. The fixing member 42 and angle defining part 41 have a guiding concave part 81 and guiding protrusion part 80. After inserting the joint member 4 into the concave groove 50 and positioning the angle defining part 41 and the fixing member 42, the nut part 44 is tightened with screw to push the fixing member 42 against the angle defining part 41 through the pressing part 43 to cause the fixing member 42 to rotate up to an attitude in which the guiding protrusion part 80 and the guiding concave part 81 are fitted to each other, and then a peripheral edge part of the narrow width part 51 is held by the fixing member 42 and the nut part 44 kept under the above attitude.</p> |
