Further, since the inside of the bulging portion 381 can be enlarged, electrical components such as the magnets 385, 386, the sensor substrate 388, and the container sensor 389 can be accommodated. In addition, since the electrical components are stored inside the bulging portion 381, it is not necessary to store these electrical components in another space, and the storage capacity of the refrigerator 10 can be increased.

  Further, the lower container 62 is horizontally supported in the front-rear direction by the moving protrusion 632 and the moving leg 635, and can be kept horizontal even when stored in the chilled chamber 42 and pulled out.

  Further, since the moving leg 635 is wider than the groove 384 and swells toward the center, the lower container 62 can be stably maintained horizontally, and the moving leg 635 does not fall into the groove 384.

  In addition, since the front end portion of the movable leg portion 635 has a curved surface shape, the bulging portion 381 is not damaged even if it hits the bulging portion 381 when pulled forward.

  In addition, since a plurality of protrusions 633 protrude on the lower surface of the moving protrusion 634 and the lower ends of these protrusions 633 are in contact with the grooves 384, the friction coefficient becomes small and the protrusions 633 are easy to move.

  In addition, a tube-shaped food container or the like can be stored on the middle bottom surface 628 of the lower container 62. In this case, since there is the partition plate 621, a tube-like container or the like does not fall to the bottom plate 624 of the lower container 62.

  Further, since the moving protrusion 632 is provided on the bottom surface of the lower container 62, the moving protrusion 632 serves as a reinforcing rib, and the bottom plate 624 of the lower container 62 does not curve.

  Further, even when the support protrusions 629 provided on the left and right sides of the lower container 62 are moved along the rail 78 and are pulled out, the rear part of the lower container 62 does not jump upward.

  Further, since the flow path 383 is formed by a recess on the upper surface of the partition plate 38, the cold air returning from the refrigerator compartment 14 can be reliably sucked into the suction port 637 through the flow path 383.
