PROBLEM TO BE SOLVED: To enhance sieving efficiency by smoothing movement of articles on a screen. SOLUTION: A vibration sieve apparatus includes: a screen 8 which is composed of a steel sheet with a number of holes 14 drilled and which, while articles are moved to an terminating end from an article receiving part 8a installed in a starting end, sieves out the articles through the holes 14; a vibrator 12 for imparting vibration to the screen 8; and a large number of scrapers 22 which, on the screen 8 with spaces apart from the screen, endlessly move with prescribed spaces apart from each other from the article receiving part 8a toward the terminating end, forcing the articles to move in the terminating end direction.
