PROBLEM TO BE SOLVED: To provide a vibration-type screen which can block a gap generated between a side plate of an enclosure and a bar-like element adjacent to the side plate, and perform a correct screening operation in accordance with the grain size of an object to be screened. SOLUTION: A gap-filling protrusion 27 which is arranged between a right and a left side plate 10A and 10B of the enclosure 10 and the bar-like element 22 adjacent to the former and extends up to an almost equal position to an apex part 22A of the bar-like element 22 in such a state that the gap 26 between the right and left side plates 10A and 10B and the bar-like element 22 is arranged in one piece at a right and a left fitting flange 16 which configure a second finger device 15. Consequently, the gap 26 generated between each side plate 10A and 10B of the enclosure 10 and the bar-like element 22 can be blocked by the gap-filling projection 27 arranged in one piece at the fitting flange 16. Thus it is possible to securely prevent a medium sized screened material with a larger grain size than the gap between the bar-like elements 22 from passing through the gap 26 generated between each side plate 10A and 10B of the enclosure 10 and the bar-like element 22 and falling downward.
