A rotary latch mechanism for releasably securing a first structure relative to a second structure. The rotary latch mechanism includes a housing adapted to be attached to the first structure, an actuator assembly coupled to the housing, a linkage coupled to the actuator assembly and arranged for movement along the housing with movement of the actuator assembly, and a bolt coupled to the housing and to the linkage, the bolt arranged for pivotal movement relative to the housing with movement of the linkage. The bolt is adapted to move between a latched position engaged with the second structure to secure the first structure relative to the second structure and an unlatched position spaced apart from the second structure to allow movement of the first structure relative to the second structure.

A refrigerator includes an opening unit such that, when a second door rotates to open a second storing chamber, the second door is separated from a first door. The opening unit includes: a latch hook to be selectively inserted into a latch slot on the front surface of the first door; a pressing portion provided on a door handle of the second door, the pressing portion comprising a guide protrusion having a sloping surface; and a link portion having a contact portion on one end to contact the sloping surface and move upward/downward along the sloping surface, the other end of the link portion contacting the latch hook. When the pressing portion is pressed, the contact portion moves upward along the sloping surface, and the other end of the link portion pushes the latch hook upward with the contact portion to separate the latch hook from the latch slot.
