<p>The binoculars include right and left optical systems including right and left image stabilizing lenses, a lens holding member holding the image stabilizing lenses and being movable in a plane orthogonal to an optical axis direction, first and second guiding members disposed between the lens holding member and a base member, a first guiding mechanism allowing rolling of a first ball in a first direction between the lens holding member and the first guiding member, a second guiding mechanism allowing rolling of a second ball in a second direction between the first and second guiding members. The binoculars further include a first biasing member applying a biasing force toward the optical axis direction to the first and second guiding members, and a second biasing member applying a biasing force toward a direction orthogonal to the optical axis direction to the second guiding member.</p> |
