Problem to be solved: to provide a refrigerator which improves the workability of mounting the lid portion of the storage tank of the refrigerator and the tank body.Solution: the storage tank has a tank body, a lid member, and a locking mechanism.The locking mechanism has an engagement portion and a rotary portion provided in the tank body.The rotating portion has an engaging portion capable of engaging with the engagement portion, and is operated in the state where the lid member is placed in the tank body, and is rotated to the tank body from the outside of the tank main body, and the locking portion is engaged with the engaging portion and the engaging portion. When the user is operated in the locked state to rotate to the outside of the tank body, the engagement between the engaging portion and the engagement portion is released to unlock the lock.The cover member has a regulating portion for restricting the rotation range of the rotary member in contact with the rotary member.The regulating portion maintains the pivoting member in the posture opened to the outside of the tank body in a state in which the lid member is positioned at least vertically above the position of the tank body.Diagram
