That is, a book plate holding plate is applied to a book placed on a bookshelf, and the tilt pressure applied to the book is held down by the holding plate to prevent the book from tilting or falling.

[0003]

However, since the book end is merely formed by bending a flat sheet metal, the book end is deformed due to its strength and cannot withstand the inclination pressure of the book, thereby ensuring the inclination of the book. Could not be prevented.

[0004] Further, even when the bookshelf is almost full of books, each book is usually inclined slightly to the left and right, and the overall appearance is poor. On the other hand, in order to prevent the book from tilting, it is common practice to refill another book in the bookshelf, but the width of the refill book does not always correspond to the width of the empty space, In most cases, the books were placed on a slant.

An object of the present invention, in view of the above-mentioned conventional problems, is to provide a book inclination preventing device which can surely prevent a book from leaning on a bookshelf.

[0006]

In order to solve the above-mentioned problems, the present invention provides a book tilt prevention device comprising a pair of holding plates placed on a bookshelf and facing left and right, and a pair of holding plates. It has a structure including a width adjusting member which is connected and makes the interval between the holding plates wide and narrow.

According to the present invention, the spacing between the pressing plates can be arbitrarily changed by the width adjusting member, so that even if the space formed on the bookshelf is wide or narrow, the space can be filled properly, and the bookshelf can be filled. Tilt of the above book can be reliably prevented.
