To provide a gimbal mechanism that is high in rigidity and does not have a backlash.
The gimbal mechanism of a flying object according to embodiments has two sets of combined angular ball bearings rotatably supporting the rotation shaft of a movable body such as an antenna to the support of the flying object. The inner ring of the combined angular ball bearing is installed on the rotation shaft of the movable body by the inner ring retainer and provided with pressurization along a shaft direction. The outer ring of the combined angular ball bearing is held by a holding sleeve slidably installed in the shaft direction to the support. This holding sleeve is fixed to the support by a fixing member with the slide position adjusted in a position without backlash.
