PROBLEM TO BE SOLVED: To prevent the damage of the member by enabling the fall of a cap when immoderate power is applied to the cap in open condition. SOLUTION: The longitudinal frame 11 and the lateral frame 12 of a mobile partition wall 10 are provided with depressions, and a cord protective cover 33 is overlaid on these depressions. The cord protective cover 33 is equipped with a cover body 35 positioned within the depression 15, and a cap 36 to open and close the open side of this cover body 35. At the cover body 35, a bearing case 47 to support the shaft 57 of the cap 36 is made, and also at this bearing case 47, a slit 48 is made. When force is applied in the direction where the cap 36 opens to a certain angle or more, the partial abutment place between the cover body 35 and the cap 36 works as a force point, whereby the the shaft 57 gets out of the slit and the fall of the cap 36 becomes possible. |
