PURPOSE: To provide an anchor easy in installing a wall panel by arranging a fixing part in a leg vertically extended on a plate of a head part, and providing a hook-shaped part and an arm having an opening for engaging with a fastening screw in the fixing part.

CONSTITUTION: A fixing part 8 is arranged in an end part of a leg 6 vertically extended from a plate 3 of a head part 2 for engaging with an outside surface of a wall panel 4. The fixing part 8 includes an arm 12 and a hook-shaped part 10, and the arm 12 has an opening 18 for engaging with a tip screw part of a fastening screw 16 inserted from an opening 14 of the plate 3. Thus, when the screw 16 is fastened after positioning the wall panel 4, the arm 12 is gradually pulled in toward a rear surface of the wall panel 4, and since the arm 12 finally tightly engages with the wall panel 4, installing execution work of the wall panel 4 can be simplified.
