PURPOSE:To prevent the damage of a product and improve efficiency by suspending a product with a face plate on the front face of said product faced downward and laterally giving a shock to the end edge part of said face plate with a striking member, in the captioned device for a block for a retaining wall, etc. CONSTITUTION:A product 1 is suspended with a face plate 2 faced downward by means of a hung-up member 4. And, driving plates 9, 9 are drive with an unshown fluid pressure operated cylinder, to swing arms 6 at a certain angle within a vertical plane. Thereby, synthetic rubber striking members 5 repeatedly inflicts strikes laterally on both end edges 2a of the face plate 2. And, the face plate 2 is separated from the surface of the product and falls down onto a supporting table 3. When the face plate 2 falls on the supporting table 3, sensors 14 are operated stopping the swinging of the driving plates 9, 9. By this structure, poor manufacturing of a product can be prevented while improving efficiency.
