Title:
FILE
Document Type and Number:
Japanese Patent JP2015229309
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a problem in which although a file which has a plurality of covers formed of one resin-made plate material is provided with a resin thin part at the plate material and has adjacent covers arranged across the resin thin part, such a file has a resin thin part applied with internal stress when covers are opened and closed, so that the part deteriorates much more than other parts, and when a cover is so molded to be easy to rotate and open, the resin thin part is loaded more as a cover body thereof is rotated in the opposite direction.SOLUTION: A file according to the present invention has a plurality of cover bodies made of a first material and a hinge body formed of a second material having higher elasticity than the first material, and one cover body is joined with the other cover body through the hinge body. Consequently, when one cover body is rotated relatively to the other cover body to open and close the file, internal stress generated owing to the rotation is absorbed with the high elasticity of the hinge body.
