Image blur correction apparatus mounted on optical equipment, and image pickup apparatus

An image blur correction apparatus comprising:

• a lens holder configured to hold a lens;
• a drive unit configured to move said lens holder;
• a base member configured to support said lens holder in such a manner that said lens holder is movable in a direction perpendicular to an optical axis, wherein said lens holder is disposed on a subject side of said base member, and wherein said base member comprises an engagement portion having an opening disposed in a direction around the optical axis, and part of said lens holder is engaged with the engagement portion to inhibit movement of said lens holder in the direction of the optical axis;
• and
• a rotation inhibition member configured to inhibit movement of said lens holder in the direction around the optical axis,
• wherein said rotation inhabitation member has a first connection part which connects with said base member and a second connection part which connects with said lens holder,
• said base member has a first engagement part which engages with the first connection part,
• said lens holder has a second engagement part which engages with the second connection part,
• the first connection part and the first engagement part are engaged with each other so that said rotation inhabitation member is movable in a first direction perpendicular to the optical axis in combination with said lens holder with respect to said base member, and
• the second connection part and the second engagement part are engaged with each other so that said rotation inhabitation member is movable in a second direction perpendicular to the optical axis with respect to said lens holder.
