PROBLEM TO BE SOLVED: To efficiently execute the shake-out of a casting by fixing the casting to a supporting member and giving complex vibration composed of an arc vibration and a vertical vibration to a support member. SOLUTION: For example, the casting 31 of a cylinder head, is laid on the support member 23 and a fixed arm 33 is fastened with a bolt 34 to fix the casting 31. Then, when a vibrating means 24 is worked, since the complex vibration of the arc vibration and the vertical vibration is acted to the casting 31, core etc., forming a water jacket of the cylinder head is started to collapse and the sand is discharged. Further, when an impact vibration with a hammer means 37 is intensely applied to the casting 31 at the same time of or before and after the above vibration, the molding sand of the core etc., is surely collapsed and discharged to the outer part of the casting 31. Furthermore, the sand stuck on the surface part of the casting 31 is surely separated with these two kinds of vibrations, too. The sand dropped down on the supporting member 23 is dropped down in the surrounding part with the conveyability of the vibrating means 24.
