ABSTRACT:
This present invention is related to a key ring for keeping a key. The key ring includes a ring body, which has cut planes at both ends thereof. A concave portion (30) is formed at a predetermined place of the key ring (10) and is curved in a direction and in a body with the key ring (10). One of the cut planes is projected toward an inner side of the concave portion (30), and the key (40) is inserted into the ring body (10). With this configuration, it is easy to keep and take out a key by less force by forming a concave portion at a predetermined position of a ring body made of a metallic material and making one cut plane at one end of the concave portion so as to be projected toward an inner side of the concave portion and the other cut plane so as to correspond to the other end of the concave portion.
