PROBLEM TO BE SOLVED: To suppress expansion and shrinkage of parts caused by a change in ambient temperatures to reduce a backlash involved especially in a drive mechanism in a camera platform with panning and tilting functions. SOLUTION: The camera platform includes the drive mechanism capable of moving in panning and tilting directions. In the camera platform, a linear expansion coefficient of gears constituting the drive mechanism and that of a support plate for supporting the gears are made to be equal to each other.
