PROBLEM TO BE SOLVED: To prevent the running failure and fracture of an aseismatic moving wall structure during movement of a moving wall and to allow the structure to exhibit high aseismatic property. SOLUTION: This aseismatic moving wall structure includes a sash pulley 2, which has both a rolling member 4 freely rollingly abutting against an upper rail and a base part 5 on which the rolling member 4 is freely rotationally mounted, a hanging rod 3 provided to hang from the pulley 2, and a moving wall mounted on the lower portion of the hanging rod 3. A weight-receiving recessed face 12 forming a part of a spherical face is formed at the base part 5 of the pulley 2 and a head 3b having an abutment curved face portion 18 forming a part of the spherical face is formed at the upper end of the hanging rod 3. The abutment curved face part 18 of the head 3b of the hanging rod 3 is received by the weight-receiving recessed face 12 of the base part 5 of the pulley 2 via a number of small spherical bodies 22... so that the hanging rod 3 freely oscillates by a predetermined angleθto a plumb line M.
