PROBLEM TO BE SOLVED: To solve the problem that it is extremely inconvenient since a gap is formed between books, remaining books fall down one after another when a book set against a bookshelf or the like is removed to be read. SOLUTION: A twisted body formed by turning both end parts of a fully flexible and elastic sheet-like body of a narrow width such as a cloth or rubber in directions opposite to each other and attached on a mount is installed on the back plate of a bookshelf or the like, thereby preventing the books from falling down one after another.
