Abstract: The buckling-restrained brace that is capable of being fixed to connected portions of a structure using bolts, the brace includes: a plate member extending in an axial direction, and in which bolt holes for fixing the bolts are formed at end portions of the plate member in the axial direction; and a buckling-restrained member configured to restrain a center portion of the plate member in the axial direction to prevent the plate member from buckling, wherein the buckling-restrained member includes a pipe member surrounding the plate member from the outside in a radial direction, and a filler filling the gap between the pipe member and the plate member, and the plate member includes a fixing plate, a portion of which is embedded in the filler, and the remaining portion is protruded from the filler in the axial direction, and in which the bolt hole is formed at an end portion of the remaining portion in the axial direction.

Abstract: There is provided a lens barrel including: a rear barrel to which an imaging device is attachable, an imaging optical system leading a subject image to the imaging device, and an image blur correcting unit moving a shift lens forming the imaging optical system in a plane perpendicular to an optical axis of the imaging optical system. The image blur correcting unit includes a base supporting the shift lens in a plane perpendicular to the optical axis of the imaging optical system. The lens barrel includes a support mechanism supporting the base to be movable relative to the rear barrel along a plane perpendicular to the optical axis; and a fixing device fixing the base to the rear barrel.

Abstract: There is provided a lens barrel including an imaging optical system, and an image blur correction unit moving a shift lens forming the imaging optical system in a plane perpendicular to an optical axis of the imaging optical system. The image blur correction unit includes a second movable body holding the shift lens and provided to be movable in two directions perpendicular to each other on a plane perpendicular to the optical axis. A fixed lens holding frame holding a fixed lens forming the imaging optical system is placed in front of the second movable body. A movement control structure is provided in a region ranging from the second movable body to the fixed lens holding frame to allow movement of the second movable body in the two directions and control a range of movement of the second movable body.
