[0042] 5, the fourth fixing portion 24b has a sixth through hole 24e penetrating the fourth fixing portion 24b in the vertical direction Z. The sixth through hole 24e is a circular hole when viewed in the vertical direction Z. The inner diameter of the sixth through hole 24e is larger than the inner diameter of the third through hole 24c and the inner diameter of the fourth through hole 24d. The sixth through hole 24e is located between the two fourth through holes 24d in the front-rear direction X. The sixth through hole 24e does not necessarily have to be provided.

[0043] Of the left-right direction Y surfaces of the side wall main body portion 21 of the first side wall member 20a, the surface opposite to the side to which the fixing member 23, the second fixing member 24, the rail member 22 and the drawer rail unit 90 are attached has no other components such as metal fittings attached thereto.

[0044] The drawer rail unit 90 is cantilevered on a surface facing the right side of the first side wall member 20a of the side wall member 20. As shown in FIG.

[0045] The pair of rail members 91A, 91B each have a rectangular parallelepiped shape extending in the X direction, which is the front-rear direction. The pair of rail members 91A, 91B are disposed apart in the Y direction, which is the left-right direction. The rail member 91A is disposed on the left side, which is one side in the left-right direction Y. The rail member 91B is disposed on the right side, which is the other side in the left-right direction Y.

[0046] The pair of support members 92A, 92B each extend in the Y direction, which is the left-right direction. The pair of support members 92A, 92B are arranged apart in the X direction, which is the front-rear direction. The rail member 91A is arranged on the front side. The rail member 91B is arranged on the rear side. The pair of support members 92A, 92B each support the pair of rail members 91A, 91B. The drawer rail unit 90 is cantilevered on the surfaces of the pair of rail members 91A, 91B facing the right side of the first side wall member 20a.

[0047] 8 and 9, the locking member 93 is fixed to the first side wall member 20a. The locking members 93 are provided at positions facing the pair of support members 92A, 92B in the left-right direction. The locking member 93 has an embedded portion 93A, a shaft portion 93B, and a first locking portion 93C. The shaft portion 93B and the first locking portion 93C protrude to the right from the first side wall member 20a.

[0048] The embedded portion 93A is embedded in the surface of the first sidewall member 20a facing the right side. The shaft portion 93B is provided at the tip of the embedded portion 93A and is cylindrical and protrudes from the first sidewall member 20a to the right. The diameter of the shaft portion 93B is larger than the diameter of the embedded portion 93A. The first locking portion 93C is provided at the tip of the shaft portion 93B and is disk-shaped with a diameter larger than that of the shaft portion 93B. When the embedded portion 93A is embedded in the first sidewall member 20a, the shaft portion 93B engages with the surface of the first sidewall member 20a facing the right side, thereby forming a gap 93D between the first locking portion 93C and the first sidewall member 20a.

[0049] The first side wall member 20a has fitting holes 94 on both vertical sides sandwiching the locking member 93. The fitting holes 94 are circular recesses recessed to the left from the surface of the first side wall member 20a facing the right side.

[0050] The pair of support members 92A, 92B have the same configuration, and therefore the following description will representatively focus on the support member 92A. The support member 92A has a first structural wall 95A, a second structural wall 95B, and a third structural wall 95C.

[0051] The first structural wall 95A is located on the left side in the left-right direction and extends in the up-down direction. The second structural wall 95B is located on the right side in the left-right direction and extends in the up-down direction. The third structural wall 95C connects the lower end of the first structural wall 95A and the lower end of the second structural wall 95B and extends in the left-right direction. The cross-sectional area of ​​the third structural wall 95C perpendicular to the left-right direction increases from the right side to the left side in the left-right direction. By increasing the cross-sectional area of ​​the third structural wall 95C perpendicular to the left-right direction from the right side to the left side in the left-right direction, the moment of inertia becomes large, and even when the support member 92A is cantilevered by the first sidewall member 20a, the deflection of the second structural wall 95B can be suppressed.

[0052] The first structural wall 95A is supported by the first side wall member 20a. The first structural wall 95A has a second locking portion 96 and a holding portion 97.

[0053] The second locking portion 96 is located at the left end of the first structural wall 95A. The second locking portion 96 contacts the surface of the first side wall member 20a facing the right side. The second locking portion 96 is provided on the first structural wall 95A via a gap 95D. The second locking portion 96 has a left-right dimension smaller than the left-right dimension of the gap 93D. As shown in FIG. 10, the second locking portion 96 has an insertion hole 96A, a locking hole 96B, and a protrusion 96C.

[0054] The insertion hole 96A is a circular through-hole that penetrates the second locking portion 96 in the left-right direction. The insertion hole 96A communicates with the gap 95D. The diameter of the insertion hole 96A is larger than the diameter of the first locking portion 93C of the locking member 93. As shown in FIG. 11, the first locking portion 93C can be inserted into the gap 95D from the left side through the insertion hole 96A.

[0055] The locking hole 96B is a circular through-hole that penetrates the second locking portion 96 in the left-right direction. The locking hole 96B is located in the center of the second locking portion 96 in the front-rear direction. The locking hole 96B communicates with the gap 95D. The locking hole 96B is located above the insertion hole 96A and communicates with the insertion hole 96A. The locking hole 96B has a minimum dimension t in a direction perpendicular to the direction in which it is connected to the insertion hole 96A that is larger than the diameter of the shaft portion 93B of the locking member 93 and smaller than the diameter of the first locking portion 93C.

[0056] As shown in Fig. 12, the shaft portion 93B can move from the insertion hole 96A to the locking hole 96B with the first locking portion 93C inserted into the gap 95D. When the shaft portion 93B is positioned in the locking hole 96B, the second locking portion 96 is inserted into the gap 93D as shown in Fig. 9. When the second locking portion 96 is inserted into the gap 93D, it locks with the first locking portion 93C from the left side in the left-right direction. By locking the second locking portion 96 with the first locking portion 93C from the left side, it is possible to prevent the support member 92A having the first structural wall 95A from coming off the first side wall member 20a.

[0057] In the drawer rail unit 90 of the embodiment, the first locking portions 93C of the two locking members 93 provided on the first side wall member 20a are inserted into the insertion holes 96A in the pair of support members 92A, 92B, and then the pair of support members 92A, 92B are moved until the shaft portion 93B is positioned in the locking hole 96B, thereby easily supporting the pair of support members 92A, 92B in a cantilevered manner on the first side wall member 20a.

[0058] If the insertion hole 96A and the locking hole 96B are in the same position in the up-down direction, friction generated when the third drawer portion 43 described below moves in the front-rear direction may cause the pair of support members 92A, 92B to move in the front-rear direction, causing the first locking portion 93C to be positioned in the insertion hole 96A and releasing the locked state of the second locking portion 96. By locating the locking hole 96B above the insertion hole 96A, it is possible to prevent the locking state of the second locking portion 96 from being released due to friction generated when the third drawer portion 43 moves in the front-rear direction.

[0059] The insertion hole 96A is positioned offset from the locking hole 96B in the front-rear direction. If the insertion hole 96A and the locking hole 96B were in the same position in the front-rear direction, for example, when the support member 92A tilts downward, the support member 92B moves upward, and the first locking portion 93C is positioned in the insertion hole 96A, which may release the locked state of the second locking portion 96. By positioning the insertion hole 96A offset from the locking hole 96B in the front-rear direction, it is possible to prevent the locking state of the second locking portion 96 from being released even if the support member 92A tilts downward.

[0060] The protrusions 96C are provided on both vertical sides of the locking hole 96B. The protrusions 96C protrude to the left from the second locking portion 96. The protrusions 96C are fitted into the fitting holes 94 when the shaft portion 93B is positioned in the locking hole 96B. By fitting the protrusions 96C into the fitting holes 94, the pair of support members 92A, 92B can be positioned in the vertical and front-rear directions relative to the first side wall member 20a.

[0061] The holding portion 97 holds the rail member 91A. The holding portion 97 of the first structural wall 95A is symmetrical in the left-right direction with the holding portion 97 that is provided on the second structural wall 95B and holds the rail member 91B, so only the holding portion 97 of the first structural wall 95A will be described below.

[0062] As shown in FIG. 13, the holding portion 97 has a first holding wall 97A, a second holding wall 97B, a third holding wall 97C, a first claw portion 97D, and a second claw portion 97E.

[0063] The first retaining wall 97A is located inside the second locking portion 96 in the left-right direction and extends in the up-down direction. The first retaining wall 97A retains the rail member 91A from the outside in the left-right direction. The second retaining wall 97B extends inside in the left-right direction from the upper end of the first retaining wall 97A. The second retaining wall 97B retains the rail member 91A from above. The second retaining wall 97B is elastically deformable in the up-down direction. The third retaining wall 97C extends inside in the left-right direction from the lower end of the first retaining wall 97A. The third retaining wall 97C retains the rail member 91A from below.

[0064] The second claw portion 97E protrudes upward from an inner end portion in the left-right direction of the third retaining wall 97C. The second claw portion 97E engages with the rail member 91A from the inner side in the left-right direction. The first claw portion 97D protrudes downward from an inner end portion in the left-right direction of the second retaining wall 97B. The first claw portion 97D engages with the rail member 91A from the inner side in the left-right direction.

[0065] The rail member 91A held by the holding portion 97 is inserted from the right side into a space surrounded by a first holding wall 97A, a second holding wall 97B, and a third holding wall 97C that open to the right side. When the rail member 91A is attached to the holding portion 97, the second holding wall 97B elastically deforms upward, causing the first claw portion 97D to move upward, so that the rail member 91A can be attached without any problems. The rail member 91A is held in the up-down direction by the second holding wall 97B and the third holding wall 97C. The rail member 91A is held in the left-right direction by the first holding wall 97A, the first claw portion 97D, and the second claw portion 97E.

[0066] 14, the second retaining wall 97B viewed from below is divided into a first portion A1, a second portion A2, and a third portion A3 by a concave-shaped first slit SL1 and a concave-shaped second slit SL2. The first portion A1, the second portion A2, and the third portion A3 are each elastically deformable independently from one another in the up-down direction on the right-hand tip side starting from the first retaining wall 97A connected to the left end portion.

[0067] A plurality of first claws 97D are provided. The first claws 97D include a third claw 97F, a fourth claw 97G, and a fifth claw 97H. The third claw 97F is provided at the right end of the first portion A1 and extends in the front-rear direction. The fourth claw 97G is provided at the right end of the second portion A2 and extends in the front-rear direction. The fifth claw 97H is provided at the right end of the third portion A3 and extends in the front-rear direction.

[0068] The third claw portion 97F has the shortest distance in the left-right direction Y from the first retaining wall 97A, and the fourth claw portion 97G and the fifth claw portion 97H have successively longer distances. Since the third claw portion 97F, the fourth claw portion 97G, and the fifth claw portion 97H have different distances in the left-right direction Y from the first retaining wall 97A, the rail member 91A having a width according to the distance in the left-right direction Y from the first retaining wall 97A can be arbitrarily selected and used. For example, when the rail member 91A having a width that engages with the fifth claw portion 97H is attached to the retaining portion 97, the first portion A1 and the second portion A2 are elastically deformed upward independently of the third portion A3, so that the third claw portion 97F and the fourth claw portion 97G move upward, and the rail member 91A can be attached without any hindrance.

[0069] Each of the pair of support members 92A, 92B has either a second protrusion portion that protrudes in the left-right direction or a second fitting hole portion that is recessed in the left-right direction and into which the second protrusion portion fits, and each of the pair of rail members 91A, 91B has the other of the second protrusion portion and the second fitting hole portion.

[0070] 9 and 13, in the drawer rail unit 90 of the embodiment, the support member 92A has a second protrusion 97J, and the rail member 91A has a second fitting hole 91C. Alternatively, the rail member 91A may have the second protrusion, and the support member 92A may have the second fitting hole.

[0071] The second protrusion 97J protrudes to the right from the first retaining wall 97A of the first structural wall 95A. The second protrusion 97J has an elliptical shape extending in the vertical direction. The second fitting hole 91C is provided at a position facing the second protrusion 97J in the left-right direction. The second fitting hole 91C has an elliptical shape extending in the vertical direction. The second fitting hole 91C penetrates the rail member 91A in the left-right direction. When the rail member 91A is held by the retaining portion 97, the second protrusion 97J fits into the second fitting hole 91C, thereby positioning the support member 92A and the rail member 91A in the vertical and front-rear directions.

[0072] As shown in FIG. 3, the second sidewall member 20b has the same configuration as the first sidewall member 20a, except that the drawer rail unit 90 is not provided and the second sidewall member 20b has a shape symmetrical to the first sidewall member 20a in the left-right direction Y. The rear end of the sidewall main body portion 21 of the third sidewall member 20c, which is on the -X side, contacts the front surface of the support portion 10, which is on the +X side.
