PROBLEM TO BE SOLVED: To provide an improved screw receiver member capable of effectively preventing corotation even if the screw receiver member is applied to a hollow wall composed of a relative thin hard wall plate and not producing any crack at the wall plate itself.SOLUTION: A screw receiver member for attaching an optional holding member of a device through a screw fixing to an attaching hole arranged at a wall plate of a hollow wall comprises an anchor 1 inserted into the attaching hole, and a fixing plate 2 for restricting rotation of the anchor. The anchor has a cylinder 10 having a first open hole 11 in an axial direction, a flange 18 having a first connecting surface at a surface arranged at one end side of the cylinder, and a pair of bent arms 13 expandable in a substantially pantograph form arranged at the other end side of the cylinder. The fixing plate has a concave part 20 including a second open hole 21 coaxial with the first open hole, and a second connecting surface connected to the first connecting surface through fitting of the flange.SELECTED DRAWING: Figure 6 |
