PROBLEM TO BE SOLVED: To provide a signboard attachment device which is capable of easily and surely attaching a signboard to a pole.SOLUTION: The signboard attachment device includes an upper attaching tool 2 and a lower attaching tool 3 to be removably attached to an upper horizontal frame 12 and a lower horizontal frame 14 of a signboard 1 respectively. The attaching tools 2 and 3 include: attaching members 21A, 21B, 31A and 31B which are located on the left side and the right side thereof and are to be removably fixed to the signboard 1; and an elastically expansible rubber string 5 which is stretched between these attaching members and is stretched around one side peripheral surface of the pole in a state where the signboard 1 is located along the other side peripheral surface of the pole. One ends of chain members 4 and 6 connecting a plurality of annular bodies 41 and 61 are coupled to the left and right attaching members 21A, 21B, 31A, and 31B, and both ends of rubber strings 5 and 7 are locked to one of annular bodies 41 and 61 of the chain members 4 and 6. |
