PROBLEM TO BE SOLVED: To provide a miniaturized pivot unit capable of improving the impact resistance by increasing the moment rigidity. SOLUTION: The centers of rolling elements 7, 7 of two rolling bearings 3, 3 mounted between a fixed shaft 1 and a housing 2 are respectively offset from the centers in the width direction of the bearing 3, 3, and a distance B between the centers in the width direction of the bearings is less than a distance A between the centers of the rolling elements.
