To provide a hinge capable of realizing temporary fixing of a hinge arm in an open position, which is simple in structure and inexpensive.
This hinge includes a hinge base and the hinge arm 940 whose base end is supported on the hinge base. A rotation locking body 913 is provided in the inside of the hinge base. The inside of the hinge arm 940 is provided with an abutting body 945 turned with the rotation of the hinge arm 940 and a hammer 950. When the groove of the rotation locking body 913 is put in the locking position, the end part of the abutting body 945 pointing in the closing direction enters the groove to be disabled from rotating more than that, and when the groove is put in a free position, locking is not performed.
