PURPOSE: A supportive structure for adjusting slant of projector is provided to easily adjust slant on a large scale and to easily balance levels of the supportive structure placed on both sides. CONSTITUTION: A structure comprises a supporter(20); a screw holder; a spring(34); a handle(40); and a case. The supporter has a screw part formed on a periphery thereof to adjust slant of a projector. The screw holder has a diameter larger than the screw part of the supporter and an internal screw part to freely fix or detach the supporter. The spring keeps engagement between the screw part and the internal screw part when the supporter and the screw holder have to be fixed to each other. The handle releases engagement between the screw part and the internal screw part by overcoming returning force of the spring when the coupling between the supporter and the screw holer has to be released. The case comprises an upper case(50) and a lower case(60) to fix the screw holder to a main body of a projector. |
