PROBLEM TO BE SOLVED: To provide a vibration screen which has few components and is easily assembled, nonetheless has the securely sealed interior.SOLUTION: A vibration screen 100 according to the present invention includes vibration means 10, a base plate 20 combined to the vibration means 10, a cylindrical container 30 disposed on the base plate 20, a sieve mesh 50 vertically partitioning the interior space of a container 30, and a regulation member 70 for regulating a vertical-direction distance between the base plate 20 and the top edge of the container 30a. The container 30 has a plurality of short cylindrical frame bodies 31, 32 which are vertically stacked, and elongation means 40 for elongating the container 30 in a vertical direction. The sieve mesh 50 is sandwiched and supported between a first support surface which is horizontally provided in the lower frame body 31 and a second support surface which is horizontally provided in the upper frame body 32. When the elongation means 40 is operated, a compressive load acts on a connection part between the frame bodies 31, 32, and thus both frame bodies are securely coupled to each other, whereby the interior of the vibration screen 100 can be securely sealed. |
