Abstract:
1. An image blur correction apparatus comprising: a lens unit configured to include at least one lens and configured to be turnable in a first direction which is a direction about a first supporting axis that is orthogonal to a light axis of the at least one lens with respect to an outer housing, and in a second direction which is a direction about a second supporting axis that is orthogonal to the light axis and the first supporting axis; a fixed member configured to be arranged on an outer periphery side of the lens unit and configured to turnably support the lens unit in the first direction and the second direction; a first drive unit configured to turn the lens unit in the first direction; and a second drive unit configured to turn the lens unit in the second direction, wherein a spherical slide portion is formed on an outer periphery of the lens unit around a reference point as a center of the spherical slide portion, wherein the reference point is a point in the lens unit such that the first supporting axis vertically extends through the reference point and the second support axis horizontally extends through the reference point, wherein a spherical support portion is formed on an inner periphery of the fixed member around the reference point as a center of the spherical support portion, wherein the spherical slide portion is capable of sliding along the spherical support portion when the lens unit is turned in the first direction or the second direction, and wherein a plurality of spheres, capable of rolling when the lens unit is turned, are arranged between the spherical slide portion of the lens unit and the spherical support portion of the fixed member.
