PROBLEM TO BE SOLVED: To provide a sound barrier having a structure in which its height can be increased more than before, and snow, rainwater, and the like hardly remain while a sound diffraction effect is obtained.SOLUTION: A sound barrier 100 has a body wall 1 installed in an upright posture, and a rotation part 2 disposed on the body wall 1 installed in an upright posture. The rotation part 2 constituting the sound barrier 100 has a rotation axis 3 rotatable with the lengthwise direction D of the body wall 1 as its axis, and three rotation walls 4 attached to the rotation axis 3 so as to extend from the rotation axis 3 in the radial direction of the rotation axis 3. |
