<p>PROBLEM TO BE SOLVED: To obtain a device for attaching equipment to a pole which holds a fitting band without deteriorating the rigidity of a supporting band and can perfectly withstand external forces by connecting the fitting band with the supporting band by inserting the former into the latter from above and press-contacting the front end of a fixing screw in a tapped hole provided in the peripheral surface of the supporting band with the internal surface of the fitting band. SOLUTION: A band body 6 is fitted to an electric pole D and a sporting band 5 is brought into contact with the peripheral surface of the pole D so that the band 5 can be protruded from the peripheral surface, and then, a fitting band 3 is inserted into the supporting band 5 from above. A projector 4 is clamped to an engaging edge 10 and a nut material 11 is assembled with a holding piece 17. Then a fixing screw 13 is screwed in a threaded hole and the front end of the screw 13 is press-contacted with the internal surface 3' of the fitting band 3 through a through hole 14. Therefore, a device for attaching equipment to the pole can exert holding forces against loads from the front, rear, left, and right sides by holding one side of the fitting band 3 between the front end of the screw 13 and internal surface of the supporting band 5. In addition, when the positional relation between the threaded hole and the through hole 14 is maintained constantly, the rotating and moving amounts of the fitting band 3 can be made zero and a stable fitting state can be obtained without making the diameter of the through hole 14 different from the outside diameter of the screw 13.</p> |
