  The upper plate portion 46 and the lower plate portion 47 are provided such that the left end portion or the right end portion of the shaft 42 is located therebetween. The upper plate portion 46 extends linearly in the front-rear direction from the rear side region 45c to the front side region 45a.

  The lower plate portion 47 includes a first extending portion 47a, an inclined portion 47b, and a second extending portion 47c. The first extending portion 47a extends linearly in the front-rear direction in the front region 45a. In the intermediate region 45b, the inclined portion 47b is inclined so that the distance W from the upper plate portion 46 in the vertical direction decreases toward the rear. The second extending portion 47c extends linearly in the front-rear direction in the rear side region 45c. The second extending portion 47c is located above the first extending portion 47a.

  In the rear side region 45c, the vertical distance between the upper plate portion 46 and the lower plate portion 47 is narrow, and the rotation of the shaft 42 is limited, and only sliding movement is possible. In the rear side region 45 c, the shaft 42 slides in conjunction with the sliding movement of the drawer door 4 regardless of whether the lock mechanism 50 is locked. Moreover, since the rotation of the shaft 42 is restricted, the drawer door 4 maintains the state in the first posture.

  Thus, the rotation restricting portion 49 is configured by the upper plate portion 46 and the second extending portion 47c located in the rear region 45c. The rotation limiting unit 49 maintains the state where the drawer door 4 is in the above-described first posture by limiting the rotation of the shaft 42. The rotation restricting portion 49 extends forward from the rear surface (inner surface of the rear wall portion 6b) side of the storage chamber 6.

  In the intermediate region 45b, the lower plate portion 47 is inclined so that the distance W between the lower plate portion 47 and the upper plate portion 46 in the up-down direction increases toward the front. For this reason, in the intermediate region 45 b, when the lock by the lock mechanism 50 is released, the shaft 42 can rotate within a range until it comes into contact with the lower plate portion 47.

  In the front side region 45 a, the vertical distance between the upper plate portion 46 and the lower plate portion 47 is wide. Also in the front region 45a, when the lock by the lock mechanism 50 is released, the shaft 42 can be rotated in a range until it comes into contact with the lower plate portion 47. In the front side region 45a, the space in the vertical direction between the upper plate portion 46 and the lower plate portion 47 is wider than that in the intermediate region 45b, and the rotation range is widened.

  As described above, the rotation allowing portion 48 is configured by the upper plate portion 46, the first extending portion 47a, and the inclined portion 47b located in the front side region 45a and the intermediate region 45b. The rotation permission part 48 allows the drawer door 4 to take the second posture by allowing the shaft 42 to rotate. The rotation permission unit 48 is located on the front side of the rotation restriction unit 49.

  In the rotation allowing portion 48, the shaft 42 abuts on the lower plate portion 47, and the rotation of the shaft 42 is restricted, whereby the rotation of the drawer door 4 is restricted.

  FIG. 11 is a cross-sectional view showing a state before the drawer door is pulled out in the refrigerator according to the present embodiment. FIG. 12 is a cross-sectional view illustrating a state where only the drawer operation of the drawer door is completed in the refrigerator according to the present embodiment. FIG. 13 is a cross-sectional view showing a state in which the drawer door pulling operation and the pivoting operation are finished in the refrigerator according to the present embodiment. With reference to FIGS. 11 to 13, the drawer operation and the pivoting operation of the drawer door 4 will be described.

  As shown in FIG. 11, in a state before the drawer door 4 is pulled out, the drawer door 4 has a first posture parallel to the front opening 6a of the storage chamber 6 and is located at the rear end position P1. The front opening 6 a of the storage chamber 6 is blocked by the drawer door 4. In this state, the storage case 10 is stored in the storage chamber 6. The shaft 42 is located in the rear region 45c.

Thereby, it is possible to easily take out the stored items from the front side of the drawer door 4 and store them in the storage case.

  Furthermore, the storage case 10 can be taken out by allowing the storage case 10 to be attached to and detached from the pair of frames 21 in a state where the rotation operation and the pull-out operation of the drawer door 4 have been completed. Thereby, cleaning, maintenance, etc. in the storage case 10 and the storage chamber 6 can be easily performed.

  Next, when the drawer door 4 is moved rearward toward the rear end position P1 from the state where the pivoting operation and the drawer operation of the drawer door 4 are completed, the drawer door 4 is slid by being pushed backward. In this case, both ends of the shaft 42 move rearward while sliding on the lower plate portion 47.

  In the intermediate region 45b, both ends of the shaft 42 move rearward while sliding on the inclined portion 47b as the rotation forcing portion, thereby, as described above, the pair of rotational force transmission portions 43 are By transmitting the rotational force to the drawer door 4 in conjunction with the rotation of the shaft 42, the drawer door 4 rotates rearward.

  When both ends of the shaft 42 move rearward from the intermediate region 45b and reach the rear side region 45c, the rear door 4 is restricted from rotating to the rear side, and the drawer door 4 is placed in the storage chamber. 6 is in a first posture parallel to the front opening 6a.

  In the above description, the case where the drawer door 4 is moved rearward toward the rear end position P1 from the state where the pivoting operation and the drawer operation of the drawer door 4 are finished has been described as an example. In the case where the drawer door 4 is moved backward toward the rear end position P1 from the state where the rotation is not completed and only the rotation operation is completed, the shaft 42 is similarly rotated backward by the inclined portion 47b. Thus, the drawer door 4 is in the first posture.

  As described above, when the drawer door 4 is in the second posture, the inclined portion 47b causes the drawer door 4 to move to the first position by forcibly turning the shaft 42 when moving the drawer door 4 rearward. Forcibly rotate from the second position to the first position.

  Thereby, when the drawer door 4 reaches the rear end position P1, the drawer door 4 is in the first posture, so that the front opening 6a of the storage chamber 6 can be reliably closed by the drawer door 4.

  As described above, in the drawer device 100 for a refrigerator according to the present embodiment, when the drawer door 4 is in the second posture, the rotation allowing portion 48 moves the drawer door 4 rearward. In this case, there is an inclined portion 47b that forcibly rotates the drawer door 4 from the second position to the first position by forcibly rotating the shaft 42 that is interlocked with the rotation operation of the drawer door 4. By setting it as a structure, the front opening 6a of the storage chamber 6 can be reliably closed by the drawer door 4.
