Since it is necessary to expose a part of the wall to the inside of the room, there is a step inside the pillar 500 to form the wall surface 310.
Since the bamboo 340, the plaster material 330, etc. are arranged on the back surface of the 0, the space 320 inside the wall has only the width of the single brace 200.

[0006] Therefore, in a Japanese-Western mixed house, at present, there is a mixture of a single strut 200 and a cross strut 210.

[0007] Under such circumstances, when a large earthquake or the like is encountered, the power is concentrated on the single strut 200 having a low strength, and there is a possibility that the house may be seriously damaged such as collapse.

Further, since the distance between the upper and lower horizontal members differs depending on the house, there is a problem that it is necessary to make braces having different lengths at the construction site, which is troublesome.

An object of the present invention is to provide a brace that can solve the above problems.
