Abstract

PROBLEM TO BE SOLVED: To provide a storage cabinet in which drawers can be smoothly moved.SOLUTION: A storage cabinet 1 includes a cabinet body 2 and drawers 3A (3B, 3C). A rotary roller 51 is arranged in the rear end part of the drawers 3A (3B, 3C) and, on a rail 6B on the cabinet side, there is installed through the entire extending direction a fall prevention piece 62e that prevents the rotary roller 51 from falling from the rail 6B on the cabinet side. Then, on the left side face of the drawers 3A (3B, 3C), there is installed a movement regulation member 8 that comes into contact further forward than the rotary roller 51 suspended on the rail 6A on the cabinet side. As a result, the drawers 3A (3B, 3C) are restricted from rotational movement backward, with the rotary roller 51 suspended on the rail 6A on the cabinet side as the center.

Description

  The present invention relates to a storage cabinet, and more particularly to a drawer structure.

  Conventionally, with respect to the cabinet side rail that is provided with a rotating roller in the front and fixed to the side plates of the left and right cabinets, the drawer side rail that is provided with the rotating roller at the rear and provided on the left and right sides of the drawer slides back and forth. A storage cabinet configured to open and close the drawer has been proposed (see Patent Document 1).

  In this storage cabinet, one cabinet-side rail is provided with a roller fall-off prevention piece, but the other cabinet-side rail is not provided with a roller fall-off prevention piece. This is to absorb the dimensional tolerance between the cabinet inner dimension and the drawer outer dimension. In such a structure, when the drawer is to be closed by pushing only the other side from a state where the drawer is pulled out to some extent, the direction of rotation with respect to the drawer around the rotating roller suspended on one cabinet side rail Power is added to.

  Therefore, in the storage cabinet described in Patent Document 1, a guide member is provided in a part of the rear side of the front side of the cabinet side plate, and a guided member that engages with the guide member is provided in the drawer. Then, with the drawer being pulled out, the guide member is engaged with the guided member, whereby the drawer is pressed toward the other cabinet side rail. This prevents the rotating roller from falling off from the other cabinet side rail when the drawer is pulled out.

Japanese Patent No. 5171048

  However, in such a structure, at least two members, that is, a guide member provided on the side plate of the cabinet and a guided member provided on the drawer side are indispensable, and the number of parts increases accordingly.

  Further, when the drawer is pulled out to a position where the guide member and the guided member are not engaged (so-called drawer is in a half-open state), the drawer is not pressed against the other cabinet side rail. Therefore, in this state, the rotating roller falls off from the other cabinet side rail, and there is a possibility that the drawer cannot be smoothly moved back and forth with respect to the cabinet body.

  This invention is made | formed in view of the said reason, and it aims at providing the storage cabinet which can move drawer | drawer smoothly, aiming at reduction of a number of parts.

(1) A storage cabinet according to the present invention has a cabinet body in which a pair of left and right rails extending in the front-rear direction are arranged inside, and a rotation roller suspended on each of the pair of rails. A drawer that can be pulled forward by rolling on each of the rails. One of the pair of left and right rails is provided with a drop-off preventing piece that prevents the rotating roller from falling off the rail in the extending direction, and is suspended on one of the pair of left and right rails on the other side of the drawer. The cabinet main body is provided with a movement restricting member that restricts the other side portion of the drawer from rotating rearward about the rotating roller by contacting the front side of the rotating roller.

  Here, for example, it is assumed that, in a state where the drawer is pulled out, the user presses the other rail side different from the one provided with the drop-off preventing piece in the drawer toward the rear of the cabinet body. A force is applied to the drawer in a direction in which it is rotated backward about one rotating roller suspended on one rail provided with a drop-off preventing piece.

  On the other hand, according to the present configuration, the drawer rotates forward with respect to the rotating roller by contacting the front side of the other side surface of the drawer with respect to the rotating roller suspended on one of the pair of rails. A movement restricting member for restricting the movement is provided. As a result, even when the force is applied in a state where the drawer is pulled out, the movement restricting member restricts the drawer from rotating backward about the rotating roller suspended on the one rail. Accordingly, when the force is applied in a state where the drawer is pulled out, the other rotating roller can be prevented from falling off from the rail, so that the drawer can be moved smoothly.

  In addition, since the movement restricting member only needs to be provided in the cabinet body, compared to the configuration in which the rotational movement of the drawer is restricted by providing a guide member and a guided member on both the cabinet body and the drawer and engaging them. Thus, the number of parts can be reduced.

(2) Further, in the storage cabinet according to the present invention, the movement restricting member is attached to the movement restricting rotating roller whose rotation axis is directed in the vertical direction, and the cabinet main body, and rotates the movement restricting rotating roller. And a support member that is freely supported, and the movement restricting rotary roller may be disposed in a state of being substantially in contact with the outer surface of the side plate of the drawer.
According to this configuration, the movement restricting rotation roller is arranged in contact with the outer surface of the drawer side plate. Thereby, it is possible to suppress the drawer from rotating about the one rotation roller suspended on the rail provided with the drop-off preventing piece while maintaining smoothness when the drawer is moved with respect to the cabinet body. .

(3) Moreover, the storage cabinet which concerns on this invention may be arrange | positioned so that the said movement control member may not protrude outside the said cabinet main body.
According to this configuration, since the movement restricting member is arranged so as not to protrude outside the cabinet body, the movement restricting member is not conspicuous when the storage cabinet is viewed from the outside. Can be planned.

(4) In the storage cabinet according to the present invention, the cabinet body has a rectangular box shape having left and right side walls, the pair of rails are attached to the left and right side walls, and the movement restricting member is The left and right side walls may be provided at the front end portion of the side wall to which the other rail different from the one rail provided with the drop-off preventing piece is attached.
According to this configuration, since the movement restricting member is provided at the front end portion of the side wall of the cabinet body, it is possible to increase the effect of preventing the rotary roller from falling off. In addition, for example, the movement restriction member can be attached relatively easily as compared with the configuration in which the movement restriction member is provided behind the front end of the cabinet body. Therefore, it is relatively easy to attach the movement restricting member to the cabinet body.

(5) Further, in the storage cabinet according to the present invention, the cabinet body has a rectangular box shape having left and right side walls, the pair of rails are attached to the left and right side walls, respectively, and the drawer is When formed in a rectangular box shape having left and right side plates, each of the left and right side plates is arranged facing the rail, and the movement restricting member is in a state where the side plate of the drawer is parallel to the rail, The tip portion may be constituted by a protruding member spaced from the outer surface of the drawer side plate.
According to this structure, since the structure of the movement control member is simplified, there exists an advantage that manufacture of a movement control member is easy. Further, since the distal end portion of the movement restricting member is separated from the outer surface of the drawer side plate, when the drawer is moved relative to the cabinet body, the drawer side plate is less likely to be caught by the distal end portion of the movement restricting member. . Thereby, the drawer can be moved smoothly.

  According to the present invention, it is possible to smoothly move the drawer while reducing the number of parts.

Here, a gas stove 104 is installed on the upper side of the storage cabinet 1A. A sink 105 is installed on the upper side of the storage cabinet 1C. Hereinafter, the storage cabinet 1B will be described.

FIG. 2 is a perspective view of the storage cabinet 1 (1B) according to the present embodiment. Hereinafter, the storage cabinet 1B in FIG. 1 will be described as “storage cabinet 1”.
The storage cabinet 1 includes a cabinet body 2, an upper drawer 3A, a middle drawer 3B, and a lower drawer 3C.
The cabinet body 2 is formed in a rectangular box shape. Cabinet-side rails 6A and 6B extending in the front-rear direction are attached to the inside of the left and right side walls 2a and 2b of the cabinet body 2. These cabinet side rails 6A and 6B can be attached to the side walls 2a and 2b by screws or the like, for example.

The drawer 3A (3B, 3C) includes a rectangular plate-like bottom plate 3a, a rectangular plate-like front plate 3b provided at the front end of the bottom plate 3a, and an upper surface side in the thickness direction of the bottom plate 3a from the rear end of the bottom plate 3a. And a rectangular plate-like rear plate 3c. Further, the drawer 3A (3B, 3C) has rectangular plate-like side plates 3d, 3e that are erected on the upper surface side in the thickness direction of the bottom plate 3a from both left and right ends of the bottom plate 3a. That is, the drawer 3A (3B, 3C) includes a bottom plate 3a, a front plate 3b, a rear plate 3c, and side plates 3d, 3e, and is formed in a rectangular box shape having an opening 2c on the front surface. The height of the front plate 3b is set higher than the height of the rear plate 3c and the side plates 3d and 3e.
The drawers 3A (3B, 3C) are arranged in a state where a part of each of the two side plates 3d, 3e arranged to face each other faces the cabinet side rails 6A, 6B.

  A handle 31 is attached to each of the drawers 3A to 3C. The user can move the drawers 3 </ b> A to 3 </ b> C from the cabinet body 2 in the front-rear direction by holding the handle 31.

  Furthermore, drawer side rails 5A and 5B extending in the front-rear direction are attached to upper ends of the side plates 3d and 3e of the drawer 3A (3B and 3C). The drawer-side rails 5A and 5B can be attached to the side plates 3d and 3e by screws or the like, for example.

FIG. 3 is a perspective view showing a part of the cabinet side rails 6A and 6B and the drawer 3A according to the present embodiment. Moreover, FIG. 4 is sectional drawing which looked at the storage cabinet which concerns on this embodiment from the front. Note that the drawer structure related to the drawers 3B and 3C is the same as that of the drawer 3A, and therefore detailed description thereof is omitted here.
The drawer-side rail 5A is composed of an elongated projecting piece projecting leftward from the upper end edge of the side plate 3d of the drawer 3A. The drawer-side rail 5A is continuous with a portion of the upper end edge of the side plate 3d excluding a part on the rear end side.

  The drawer-side rail 5B is elongated and protrudes rightward from the upper end of the side plate 3e of the drawer 3A. The drawer-side rail 5B is continuous with a portion of the upper edge of the side plate 3e excluding a part on the rear end side.

  Moreover, the rotation roller 51 is attached to the outer surface side in each of a part of said rear end side of the side plates 3d and 3e. Here, the drawers 3A (3B, 3C) can be drawn forward by rolling the two rotating rollers 51 with the cabinet-side rails 6A, 6B, which will be described later, from the state of being housed inside the cabinet body 2. It is possible.

  The cabinet-side rail 6A has an elongated rectangular shape in plan view, and includes a fixed piece 61a, an upper protruding piece 61b, and a lower protruding piece 61c. Here, the fixing piece 61a is fixed to the side wall 2a of the cabinet body 2 with screws or the like. The upper protruding piece 61b protrudes rightward from the upper end edge of the fixed piece 61a. The lower protruding piece 61c protrudes to the right from the lower end edge of the fixed piece 61a. A cabinet-side rotating roller 61d that can rotate about the thickness direction of the fixed piece 61a as a rotation axis is provided at the front end of the cabinet-side rail 6A.

The cabinet-side rail 6B has an elongated rectangular shape in plan view, and includes a fixed piece 62a, an upper protruding piece 62b, a lower protruding piece 62c, and a drop-off preventing piece 62e. Here, the fixed piece 62a is fixed to the side wall 2a of the cabinet body 2 with screws or the like. The upper protruding piece 62b protrudes leftward from the upper end edge of the fixed piece 62a. The lower protruding piece 62c protrudes from the lower end edge of the fixed piece 62a to the left side. Further, a cabinet-side rotating roller 62d that can rotate around the thickness direction of the fixed piece 62a is provided at the front end of the cabinet-side rail 6B. The drop prevention piece 62e protrudes downward from the leading edge of the upper protruding piece 62b.
As described above, the left cabinet-side rail 6A does not have a drop-off prevention piece, but the right cabinet-side rail 6B has a drop-off prevention piece 62e.

Here, as shown by the arrows in FIG. 3, in the drawer 3A, the left and right drawer side rails 5A and 5B are fitted between the upper protruding pieces 61b and 62b and the lower protruding pieces 61c and 62c of the cabinet side rails 6A and 6B. Include.
In this case, as shown in FIG. 4, the rotating roller 51 of the drawer 3A is placed on the lower protruding pieces 61c and 62c of the cabinet side rails 6A and 6B so as to be able to roll. The drawer side rail 5A and the drawer side rail 5B are placed on the cabinet side rotating rollers 61d and 62d of the cabinet side rails 6A and 6B.

  Then, the cabinet side rotation rollers 61d and 62d of the cabinet side rails 6A and 6B rotate and the rotation roller 51 on the drawer 3A side rolls so that the drawer side rails 5A and 5B become the cabinet side rails 6A and 6B. On the other hand, it can move back and forth. Thereby, the drawer 3A can be opened and closed with respect to the cabinet body 2 in the front-rear direction.

Incidentally, as shown in FIG. 4, in the storage cabinet 1, the drawer 3 </ b> A is restricted from rotating around the rotation roller 51 suspended on the cabinet side rail 6 </ b> B at the front end of the left side wall 2 a of the cabinet body 2. A movement restricting member 8 is provided.
The movement restricting member 8 includes a movement restricting rotating roller 81 and a roller support member 82 that rotatably supports the movement restricting rotating roller 81. Here, as for the rotation roller 81 for movement control, the rotating shaft J has faced the up-down direction. The roller support member 82 is attached to the side wall 2a of the cabinet body 2 with screws, an adhesive, or the like. The roller support member 82 may be provided integrally with the side wall 2a of the cabinet body 2, for example.

  Here, the sum of the radius of the rotation roller 81 for restricting movement and the distance from the inner surface of the side wall 2b of the cabinet body 2 to the rotation axis J is the outer surface of the side plate 3d of the drawer 3A and the inner surface of the side wall 2b of the cabinet body 2. Is approximately equal to the distance between. Thereby, the rotation roller 81 for movement control is arrange | positioned in the state contact | abutted to the outer surface of 3 d of side plates of drawer 3A.

  Thereby, the smoothness at the time of moving drawer 3A with respect to the cabinet main body 2 is maintainable. Further, in the case where the drawer 3A is present at the position where it is pulled out, the drawer 3A rotates rearward around the rotating roller 51 suspended on the cabinet side rail 6B provided with the drop-off preventing piece 62e. Can be suppressed.

5A and 5B show a part of the storage cabinet 1 according to the present embodiment, in which FIG. 5A shows a state where the drawer 3A is removed, and FIG. 5B shows a state where the drawer 3A is pulled out.
As shown in FIG. 5A, the movement restricting member 8 is attached to the front end of the left side wall 2 a of the cabinet body 2. As shown in FIG. 5B, the storage cabinet 1 is used in a state in which the rotation roller 81 for movement restriction is in contact with the outer surface of the side plate 3d of the drawer 3A.

  As described above, the movement restricting member 8 is provided at the front end portion of the left side wall 2 a of the cabinet body 2. Thereby, the fall prevention effect of the rotation roller 51 can be enlarged. In addition, for example, the movement restriction member 8 can be attached relatively easily as compared with a configuration in which the movement restriction member is provided behind the front end portion of the cabinet body 2. Therefore, the attachment of the movement restricting member 8 to the cabinet body 2 is relatively easy.

<2> About the effect of preventing the rotation of the rotating roller Next, the effect of preventing the rotation of the rotating roller in the storage cabinet 1 according to this embodiment will be described in comparison with a comparative example.
FIG. 6 is a schematic diagram of a storage cabinet 1001 according to a comparative example.
The storage cabinet 1001 according to the comparative example is different from the storage cabinet 1 according to the embodiment in that the movement restriction member 8 is not provided. In addition, about the structure similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted suitably.
Similarly to the storage cabinet 1 according to the embodiment, the storage cabinet 1001 according to the comparative example is not provided with the drop-off preventing piece on the left cabinet-side rail 6A. Accordingly, as shown in FIG. 6A, the drawer 3A has an angle until the side plate 3d contacts the front end T1 of the side wall 2a of the cabinet body 2 with the rotating roller 51 held by the right cabinet side rail 6B as an axis. It can be rotated by θ. At this time, the center position P1 of the rotation roller 51 on the left side of the drawer 3A is shifted to the right side when viewed from the front-rear direction.

When the amount of deviation at this time is ΔW, the interval between the two rotating rollers 51 of the drawer 3A is D, and the inclination angle of the drawer 3A is θ, the following relational expression (1) is established.

The angle θ increases as the distance D2 between the position P0 of the rotation roller 51 on the right side of the drawer 3A and the front end T1 of the side wall 2a of the cabinet body 2 decreases, and the shift amount ΔW also increases. Become.

6B, when the position P0 of the rotation roller 51 on the right side of the drawer 3A is in the vicinity of the front end T2 of the side wall 2b of the cabinet body 2, the front end T1 of the side wall 2a and the rotation The distance D2 from the position P0 of the roller 51 is the shortest. At this time, the shift amount ΔW is the largest.
Here, the shift amount ΔW is the distance W2 between the center position P1 of the left rotation roller 51 of the drawer 3A and the right edge of the cabinet side rail 6A when the drawer 3A is not inclined (FIG. 6A). Larger than the reference), the rotating roller 51 on the left side of the drawer 3A falls off.
Accordingly, as shown in FIG. 6B, it is assumed that the user presses the left side of the drawer 3A to move the drawer 3A into the cabinet body 2 (see arrow AR1 in FIG. 6B). In this case, a force is applied in the direction in which the drawer 3A is rotated about the center position P0 of the right rotation roller 51 of the drawer 3A, and the drawer 3A rotates (see arrow AR2 in FIG. 6B). . And when deviation | shift amount (DELTA) W is larger than the distance W2, the rotation roller 51 on the right side of drawer 3A will fall off.

  On the other hand, in the storage cabinet 1 according to the present embodiment, a movement restricting member that restricts the drawer 3A from rotating around the rotating roller 51 suspended from the cabinet side rail 6B at the front end of the side wall 2a of the cabinet body 2. 8 is provided.

FIG. 7 is a schematic diagram of the storage cabinet 1 according to the present embodiment.
In the storage cabinet 1 according to the present embodiment, the movement restricting member 8 is provided on the side wall 2 a of the cabinet body 2. The movement restricting member 8 is in contact with the outer surface of the side plate 3d of the drawer 3A (see point PC in FIG. 7). That is, the movement restricting member 8 is located in front of the rotating roller 51 (center position P0) suspended from the cabinet side rail 6B in the drawer 3A (see the one-dot chain line L0 in FIG. 7). When the drawer 3A attempts to rotate about the rotation roller 51 on the right side of the drawer 3A as a rotation axis, the movement restricting member 8 works to restrict the rotation. Therefore, in the storage cabinet 1, the drawer 3 </ b> A does not move the rotation roller 51 on the right side of the drawer 3 </ b> A regardless of the distance between the position P <b> 0 of the rotation roller 51 on the right side of the drawer 3 </ b> A and the front end T <b> 1 on the side wall 2 a of the cabinet body 2. It is possible to suppress rotational movement as the center. Thereby, it can suppress that the rotation roller 51 on the left side of drawer 3A falls off from cabinet side rail 6A.

  Further, as shown in FIG. 7, in the storage cabinet 1 according to the present embodiment, the movement restricting member 8 is arranged so as not to protrude to the outside of the cabinet body 2.

  Thereby, since the movement control member 8 is not conspicuous when the storage cabinet 1 is seen from the outside, the designability of the storage cabinet 1 can be improved.

<3> Summary For example, in a state where the drawer 3A (3B, 3C) is pulled out, the user can connect the other cabinet side rail 6A side different from the one provided with the drop-off prevention piece 62e in the drawer 3A (3B, 3C). Suppose that it pressed toward the back of the cabinet body 2. FIG. A force is applied to the drawers 3A (3B, 3C) in a direction in which the drawers 3A (3B, 3C) are rotationally moved rearward around one rotating roller 51 suspended from one cabinet side rail 6B provided with the drop-off preventing piece 62e. When the drawer 3A (3B, 3C) is pulled out, the two rotary rollers 51 are located at the front end of the left side wall 2a of the cabinet body 2, and the rotation radius of the drawer 3A (3B, 3C) is The smallest. In this case, the inclination angle θ of the drawer 3A (3B, 3C) becomes the largest in the configuration not including the movement restricting member (configuration related to the comparative example).

  On the other hand, in the storage cabinet 1 according to the present embodiment, the cabinet body 2 is moved to restrict the drawer 3A (3B, 3C) from rotating around the rotating roller 51 suspended on the cabinet side rail 6B. A regulating member 8 is provided. The movement restricting member 8 restricts the rotational movement of the drawer 3A (3B, 3C) by coming into contact with the front of the rotating roller 51 suspended on the cabinet side rail 6B in the drawer 3A (3B, 3C). As a result, in the state where the drawer 3A (3B, 3C) is pulled out, even if a force in the direction in which the drawer 3A (3B, 3C) is rotated backward is applied, the movement restricting member 8 is The rotational movement to the back centering on the rotating roller 51 suspended on the back is restricted. Accordingly, in the state where the drawer 3A (3B, 3C) is pulled out, when the force in the direction of rotational movement is applied, the dropping of the rotating roller 51 suspended from the cabinet side rail 6A from the cabinet side rail 6A is suppressed. can do. Thereby, drawer 3A (3B, 3C) can be moved smoothly.

  Further, the movement restricting member 8 need only be provided in the cabinet body 2. Therefore, for example, by providing a guide member and a guided member on both the cabinet body 2 and the drawers 3A (3B, 3C) and engaging them, the number of parts can be reduced compared to a configuration in which the rotational movement of the drawer is restricted. Can be achieved.

<Modification>
(1) In the embodiment, the configuration in which the movement restricting member 8 includes the rotation roller 81 for restricting movement has been described, but the configuration is not necessarily limited to the configuration having the rotation roller 81 for restricting movement. For example, it may be composed of a protruding member that prevents the drawer 3A (3B, 3C) from rotating more than a predetermined angle in a state where the drawer 3A (3B, 3C) is pulled out.

FIG. 8 is a perspective view showing a part of the storage cabinet 201 according to this modification. In addition, about the structure similar to embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted suitably.
In the storage cabinet 201, a movement restricting member 208 composed of a protruding member is provided at the front end portion of the side wall 2 a of the cabinet body 202. The movement restricting member 208 may be attached to the side wall 2a by a screw or the like, an adhesive, or the like, or may be formed integrally with the cabinet body 202.

FIG. 9 is a schematic diagram of a storage cabinet 201 according to this modification.
As shown in FIG. 9, the movement restricting member 208 is constituted by a protruding member. When the side plate 3d (3e) of the drawer 3A is in a state parallel to the cabinet side rail 6A (6B) (see the broken line portion in FIG. 9), the movement restricting member 208 has its tip T3 as the side plate 3d of the drawer 3A. Is spaced from the outer surface by a specified distance W3. Note that the drawer structure related to the drawers 3B and 3C can be configured in the same manner as the drawer structure related to the drawer 3A.

Here, the distance between the center position P1 of the rotating roller 51 suspended from the cabinet side rail 6A and the edge of the cabinet side rail 6A opposite to the side wall 2a is defined as W2. In this case, when the drawer 3A is present at the position where it is pulled out, the following relational expression (2) is established for the distance W2.

Here, D1 indicates the interval between the center positions P0 and P1 of the two rotating rollers 51. D3 is the shortest distance between the center position P0 of the rotation roller 51 suspended on the cabinet side rail 6B and the front end T3 of the movement restricting member 208.
φ indicates an angle formed by the first straight line L1 and the second straight line L2. Here, the first straight line L1 corresponds to a straight line connecting the center position P0 of the rotating roller 51 suspended from the cabinet side rail 6B and the specified position C1. Here, the specified position C1 corresponds to a position of a part separated by a distance D3 from the center position P0 of the rotating roller 51 on the outer surface of the side plate 3d when the side plate 3d (3e) of the drawer 3A is parallel to the cabinet side rail 6A. To do.
The second straight line L2 corresponds to a straight line connecting the tip end portion T3 of the movement restricting member 208 and the center position P0 of the rotating roller 51 suspended from the cabinet side rail 6B.

  In the state in which the drawer 3A is pulled out, the rotating roller 51 suspended from the cabinet side rail 6B provided with the drop-off preventing piece 62e is located at the front end of the left side wall 2a of the cabinet body 2.

  Then, as shown in FIG. 9, when the rotary roller 51 suspended on the cabinet side rail 6B is located at the front end of the left side wall 2a of the cabinet body 2, the drawer 3A moves to the side plate 3d. Suppose that the tip of 208 is tilted so that it abuts. At this time, the inclination (angle φ) of the drawer 3A is maximized. Even in this case, the center position P1 of the rotating roller 51 suspended from the cabinet side rail 6A is present on the side wall 2a side of the edge of the cabinet side rail 6A opposite to the side wall 2a side. Therefore, the rotating roller 51 suspended on the cabinet side rail 6A does not fall off the cabinet side rail 6A when the drawer 3A is inclined regardless of the position of the drawer 3A.

  According to the storage cabinet 201 described above, since the structure of the movement restricting member 208 is simplified, there is an advantage that the movement restricting member 208 is easily manufactured. Further, the distal end portion T3 of the movement restricting member 208 is separated from the outer surface of the side plate 3d of the drawer 3A (3B, 3C). As a result, when the drawer 3A (3B, 3C) is moved relative to the cabinet body 2, the side plate 3d of the drawer 3A (3B, 3C) is less likely to be caught by the tip T3 of the movement restricting member 208. Thereby, drawer 3A (3B, 3C) can be moved smoothly.

  Further, as described above, by determining the size of the movement restricting member 208 based on the relational expression (2), the size of the movement restricting member 208 can be accurately determined.

(2) In the embodiment and the modified example (1) described above, the example in which the movement restricting members 8 and 208 are attached to the side wall 2a of the cabinet body 2 with screws or the like has been described. However, the mounting structure of the movement restricting members 8 and 208 to the cabinet body 2 is not limited to these.
