Abstract: A refrigerator includes a refrigerator body and a door body. In a case where the door body is opened from a closed state to a first state, a first hinge shaft moves from a first positioning position to a second positioning position along a first positioning trajectory line with respect to a first trajectory slot, and a second hinge shaft moves from a first guiding position to a second guiding position along a first guiding trajectory line with respect to a second trajectory slot. In a case where the door body continues to be opened from the first state to a second state, the first hinge shaft moves from the second positioning position to a third positioning position along a second positioning trajectory line, the second hinge shaft moves from the second guiding position to a third guiding position along a second guiding trajectory line.
