The ice storage case 52 is accommodated in the ice making chamber 5 by pushing the groove 73 backward in conjunction with the closing operation of the ice making chamber door 51.

5 and 6 are views for explaining the open state of the ice making chamber door 51. FIG. 5 is a cross-sectional view taken along the line CC in FIG. 2, and FIG. 6 is a DD arrow in FIG. FIG. In particular, FIGS. 5 and 6 show a state in which the ice making chamber door 51 is opened to a restriction position by the stopper (not shown).
As shown in FIG. 6, the engaging portion 531 of the case arm 53 has two engaging portion pieces 531a and 531b which are arranged to face each other via a gap 531c and can be elastically deformed in the direction of the gap 531c. It has a so-called snap fit shape. Specifically, in the engagement portion 531, each of the engagement portion pieces 531a and 531b is inclined in the direction of the gap 531c due to an external force acting in the direction of the gap 531c. The base is elastically supported so as not to incline toward the gap 531c by being biased in a different direction.
Here, the engaging portion 531 has a distal end portion 531d (see FIG. 6) having an outer diameter D2 (see FIG. 6) larger than the opening dimension D1 (see FIG. 5) of the groove portion 73 in the drawing direction of the ice storage case 52. And a pressing portion 531e (corresponding to the second engaging portion) located under the tip portion 531d and having an outer diameter D3 equivalent to the opening dimension D1 of the groove portion 73. It is. If the outer diameter D3 is exactly the same as the opening dimension D1 of the groove 73, the sliding resistance of the pressing portion 531e in the groove 73 is increased, and smooth sliding of the pressing portion 531e may be hindered. Therefore, the outer diameter D3 is slightly smaller than the opening dimension D1 in order to form a clearance (gap) between the inner edge of the groove 73 so as to realize smooth sliding of the pressing portion 531e. It is desirable that the value be small. At this time, the clearance does not have to be a large clearance as in the case of sliding the ice storage case as in the case of Patent Document 1, and the user does not need to have a large clearance. Small enough that you don't feel rattling (not worried).
The distal end portion 531d is elastically deformed so that the outer diameter thereof is equal to or less than the opening dimension D1 only when the engaging portion pieces 531a and 531b are pressed in the direction of the gap 531c. Further, the pressing portion 531e is fitted into the groove portion 73 to press the groove portion 73 in the drawing direction or rearward of the ice storage case 52 in accordance with the opening operation or closing operation of the ice making chamber door 51. The ice storage case 52 is slid.

In the refrigerator X, the direction (state) of the engaging portion 531 of the case arm 53 attached to the ice making chamber door 51 is changed so as to change as follows with the rotation of the ice making chamber door 51. A relationship has been established.
Specifically, as shown in FIGS. 3 and 4, when the ice making chamber door 51 is not opened to the restriction position by the stopper (not shown), the direction of the engaging portion 531 is the engaging portion. The facing direction of the pieces 531a and 531b and the drawing direction of the ice storage case 52 do not match. For example, in the closed state shown in FIGS. 3 and 4, the engaging portion 531 is in a state in which the opposing direction of the engaging portion pieces 531 a and 531 b is perpendicular to the direction in which the ice storage case 52 is pulled out.
In this case, even if the front end portion of the ice storage case 52 is urged downward or upward and the engaging portion 531 contacts the groove portion 73, the engaging portion pieces 531a, Each of 531b does not receive a force in the direction of the gap 531c. Therefore, the engagement piece pieces 531a and 531b are not elastically deformed, and the outer diameter D3 of the tip portion 531d does not become the opening dimension D1 or less. Therefore, the engagement between the tip portion 531d and the groove portion 73 is caused by contact. Engagement or disengagement between the portion 531 and the groove portion 73 is restricted.

On the other hand, as shown in FIGS. 5 and 6, when the ice making chamber door 51 is opened to the restriction position by the stopper (not shown), the direction of the engaging portion 531 is the engaging portion pieces 531a and 531b. And the direction in which the ice storage case 52 is pulled out coincide with each other.
In this case, when the front end portion of the ice storage case 52 is urged downward or upward and the engaging portion 531 comes into contact with the groove portion 73, the engaging portion piece 531a of the engaging portion 531 is obtained. , 531b receive a force in the direction of the gap 531c. Therefore, the engagement piece 531a, 531b is elastically deformed in the direction of the gap 531c, and the outer diameter D3 of the tip 531d becomes equal to or smaller than the opening dimension D1, and the tip 531d is inserted into the groove 73 or the It is pulled out from the groove 73. Therefore, the pressing portion 531e is fitted into the groove portion 73, or the fitting of the pressing portion 531e and the groove portion 73 is released, and the engaging portion 531 and the groove portion 73 are engaged or disengaged. .

Hereinafter, the attaching / detaching operation of the ice storage case 52 in the refrigerator X configured as described above will be described, and the structure for attaching / detaching the ice storage case 52 in the refrigerator X will be described.
As described above, in a state where the ice making chamber door 51 is not opened to the restriction position by the stopper (not shown), the direction of the engaging portion 531 is the opposite direction of the engaging portion pieces 531a and 531b. The ice storage case 52 is in a state in which it does not coincide with the pulling direction. In this state, even if the front end portion of the ice storage case 52 is urged upward or downward and the engagement portion 531 comes into contact with the groove portion 73, the engagement portion pieces 531 a and 531 b may depend on the contact. Since it is not elastically deformed, engagement and disengagement between the engaging portion 531 and the groove portion 73 are limited.
Therefore, when the user performs the attaching / detaching operation of the ice storage case 52, first, the ice making chamber door 51 is opened to the restriction position by the stopper (not shown).

In a state of being in contact with the contact portion 83, the front end portion of the ice storage case 52 is pushed upward to urge the front end portion upward, thereby detaching the engagement portion 531 from the groove portion 73. . Specifically, by energizing the front end portion of the ice storage case 52 in the upward direction, the engaging portion pieces 531a and 531b receive a force in the direction of the gap 531c from the edge portion of the groove portion 73, and in the direction of the gap 531c. Since the outer diameter D3 of the distal end portion 531d of the engaging portion 531 is smaller than the opening dimension D1 of the groove portion 73, the engaging portion 531 is detached from the groove portion 73.
As a result, when the engaging portion 531 of the case arm 53 and the groove portion 73 of the ice storage case 52 are disengaged, the user then places the ice storage case 52 between the rail portions 81 and 81a in an inclined state. The ice storage case 52 can be removed from the ice making chamber 5 by extracting the protrusion 71 from the gap 81b.

Inserted from the gap 81b between the rail portions 81, 81a of the chamber 5 and supported by the rail portion 81 so as to be slidable, the ice storage case 52 is moved to a position where the protruding portion 71 contacts the contact portion 83. Pull out. Thereby, the groove part 73 of the ice storage case 52 and the engaging part 531 of the case arm 53 are in a state corresponding to the position in the vertical direction.
In this way, the user opens the ice making chamber door 51 to the restriction position by the stopper (not shown), and the protrusion 71 of the ice storage case 52 is slidably supported by the rail 81. In the state of being in contact with the contact portion 83, the front end portion of the ice storage case 52 is moved downward to urge the front end portion downward, thereby engaging the engagement portion 531 with the groove portion 73. (See FIGS. 5 and 6).
Specifically, by urging the front end portion of the ice storage case 52 downward, the engaging portion pieces 531a and 531b receive a force in the direction of the gap 531c from the edge portion of the groove portion 73, and the direction of the gap 531c Therefore, the outer diameter D3 of the tip portion 531d of the engaging portion 531 is smaller than the opening dimension D1 of the groove portion 73, the tip portion 531d passes through the groove portion 73, and the pressing portion 531e is By engaging with the groove 73, the engaging portion 531 and the groove 73 are engaged.

As described above, in the refrigerator X, the ice making chamber door 51 is opened to the restriction position by the stopper (not shown), and the protrusion 71 on the ice storage case 52 side is slidable on the rail portion 81. The ice storage case 52 can be attached and detached only in a specific state in which the ice storage case 52 is supported and in contact with the contact portion 83, and the ice making chamber door 51 is opened to a restricted position by the stopper (not shown).
