An object of the present invention is to provide a strut bracket that can be easily assembled and mounted even when installation space and installation work space are limited. A tension bracket (10) overlaps a first connection portion (22) and a second connection portion (32) of a first tension plate (20) and a second tension plate (30) that can be bent and displaced, and screws (50) to a nut (51). When tightened, the protrusion 40 provided on the second connection portion 32 comes into contact with the first connection portion 22, and the second connection portion 32 rotates toward the first connection portion 32 with the protrusion 40 as a fulcrum. Since the second tension plate 30 is inclined to the position retracted in the direction opposite to the rotation direction, the second butting portion 32 is kept in contact with the second mounting surface 2 and does not move. The bending plate 30 is bent and displaced to generate bending stress. Based on the bending stress, a bending force is generated in the first butting portion 22 and the second butting portion 32 of the bracket 10.
