傾けて取付けたことを特徴とする消音ボツクス。[Scope of Claim for Utility Model Registration] A sound absorbing material is attached to the wall of the bent air passage inside the box, and a ventilation fan is attached to the inlet at one end of the bent air passage, and the air brought in from the inlet by the ventilation fan is passed through the bent ventilation passage. In a sound-absorbing box that repeatedly collides with the sound-absorbing material on the road wall while being discharged from the outlet at the other end of the bent air passage, the air sent from the inlet first collides with the wall of the bent air passage. A sound deadening box characterized in that the ventilation fan is mounted at an angle so that the center line of rotation of the ventilation fan is not in the vertical direction.
