摘要： PROBLEM TO BE SOLVED: To fit a socket tool of an impact wrench onto the head part of a bolt by a grope by forming a rib shaped guiding wall part and a tilting wall part on the back of a hard cover in a bolt fastening connector. SOLUTION: A slide cover 20, a rubber grommet 30, a resin hard cover 40 are installed in order in a rectangular box-shaped housing 10, while bolt insertion holes 11a, 24, 32, 41 are arranged in a line, and a bolt 50 is passed through these bolt insertion holes 11a, 24, 32, 41. Then, a socket tool 61 of an impact wrench 60 is rotationally driven after being put over a bolt head part 51, and the tip of the bolt 50 is passed through the housing 10 so as to be screwed to a nut in the mating connector. A rib type guiding wall part 42 and a tilting wall part 43 are arranged on the back of the hard cover 40, and when the impact wrench 60 is shifted by groping, the socket tool 61 is guided toward the bolt insertion hole 41 position while colliding against these wall parts so as to be installed on the head part 51 in the bolt 50 with ease.
