The present invention relates to an advertisement placard support device which improves a mounting composition of a support pole mounted on a pole fixing body to rotatably fix the support pole in various angles with very few components to reduce manufacturing costs and guarantee safe operation and durability over a long time period of use by simplifying the composition and improving assembling. The advertisement placard support device is divided into a front fixing member and a rear fixing member to mount a shaft support unit formed on an upper end of a lower pole on a shaft unit formed on the front fixing member inside a pole fixing body fixed by a fixing piece to rotate within a rotation space formed below the pole fixing body. Pole mounting holes which mirror each other are formed on an upper portion of the rear fixing member. And a support pole is rotatably mounted on a lower pole to contact the ground with the lower pole to support an advertisement placard. An operational space is formed on the rear fixing member in a direction towards the front fixing member and the ground, and a rotational gear member formed on an upper end of the support pole is inserted into the operational space. A rotational gear and a fixing gear are formed in the operational space and the rotational gear member, respectively. Pin recesses are formed on both side walls of the operational space. Pin protrusions formed on both sides of the rotational gear member are mounted in the pin recesses. A tension part is formed on a shaft support unit towards the operational space among the shaft support units of the lower poles to press the rotational gear member formed on the upper end of the support pole. |
