に近接する仕口を外すことが考えられる。When a brace is inserted into a narrow space between pillars by a timber frame construction method, a brace is raised, and the defense force for protecting the building from the shock due to the roll of the building is attenuated. If a brace is inserted in the wide space between the pillars, the effective lighting area in the room will be blocked and the lighting area will be affected, and the effect will not be generated unless the brace is stretched symmetrically in the same wall direction. It is conceivable that the brace widens the horizontal axis based on the principle of leverage and removes the connection close to the brace for the roll of strength.
