PURPOSE: To provide a bolt-fastened connector which enables smooth fitting and removal of connector members to/from each other and which can reduce the man-hours in assembly by lessening of the number of component parts without use of any special bolt. CONSTITUTION: An over-fastening preventing mechanism 21 is composed of a plurality of nut locks 15 for holding a polygonal nut 11 rotatably in a certain axial direction position and a plurality of nut holders 19 for restricting the rotation of the nut 11. Each nut holder 19 is installed protruded from the circumferential wall of a nut accommodating chamber 14, and the foremost part 20 is in plane contact with the polygonal surface 13 of the nut 11. Each nut lock 15 is composed of a pole part 16 installed upright in such a way as surrounding the nut 11 at the bottom of the chamber 14 and a pawl 17 which is protruded in L-form in the axial direction from the top of the pole part 16 and equipped with a slope 18 in the foremost part. |
