PROBLEM TO BE SOLVED: To provide a projector support device in which the device can be made compact and the posture (position and tilt angle) of a projector can be finely adjusted with high precision.SOLUTION: The projector support device 100 includes a structure side fixing member 10 fixed to a structure, a support arm 20 one end of which is fixed to the structure side fixing member 10, and a projector connection device 30 connecting the projector 1 to the midway part or the other end of the support arm 20. The projector connection device 30 includes a first position adjustment mechanism adjusting the longitudinal direction of the projector 1, a second position adjustment mechanism adjusting the cross direction of the projector 1, a first rotation angle adjustment mechanism adjusting the rotation angle around the axis in the longitudinal direction of the projector 1, a second rotation angle adjustment mechanism adjusting the rotation angle around the axis in the cross direction of the projector 1, and a third rotation angle adjustment mechanism adjusting the rotation angle around the axis in the vertical direction of the projector 1. |
