Abstract: A hinge device for a door of a refrigerator, etc. moves the center of rotation of the door by interlocking with the opening/closing operations of the door, while stabilizing the opening/closing operations without any hindrance such as rattling. The hinge device comprises: a shaft member which is mounted on a refrigerator main body and comprises a hinge pin; a bearing member which is mounted on a door and comprises a long hole which is in contact with the hinge pin to be relatively movable or relatively rotatable with respect to the hinge pin; and a cam which is installed on the hinge pin and constitutes a cam unit by contacting a cam follower of the bearing member.

Abstract: The present invention relates to reliably performing an opening portion operation and a closing operation without using a cam and a member sliding on the cam, by including a body-side member fixed to a box body; a door-side member fixed to a door, a link mechanism connecting the body-side member to the door-side member, and a catch mechanism interposed between the link mechanisms, between the body-side member and the link mechanism, or between the door-side member and the link mechanism, and configured to bias the door-side member in a closing direction or an opening portion direction, wherein the catch mechanism includes a coil spring provided on one side of two members that are connected so as to be rotatable relative to each other through a shaft member, and a transfer arm configured to transfer an elastic restoring force of the coil spring to an other side of the two members, and the transfer arm is connected to be rotatable at a point spaced apart from the shaft member on the other side of the two members.
