Japanese Patent No. 4038461

However, the above storage case has the following dissatisfaction (problems).
(1) As shown in FIG. 10 (b), the storage case 100 stores the drawer 110 in a state of being pulled out from the front opening 124 of the outer frame 120 into the outer frame 120 by being pushed into the outer frame 120. At this time, the peak portion 114 of the drawer-side rail 113 of the drawer 110 is a portion (hereinafter referred to as a peak-shaped portion riding portion 125) located between the front opening 124 and the recess 123 in the bottom plate 121 of the outer frame 120. It gets over and fits into the recess 123 of the outer frame 120. As shown in FIG. 10A, when the drawer 110 is housed in the outer frame 120, a relatively large clearance is provided between the portion of the drawer 110 excluding the front plate 112 and the top plate 126 of the outer frame 120. (Gap) is formed. For this reason, in order to prevent dust from entering and to ensure aesthetic appearance, it is necessary to use a large front plate 112 to hide the clearance.
The drawer 110 of the storage case 100 in the illustrated example has a drawer main body 117 having a configuration in which side plate portions 116 are erected on three sides of the outer periphery of a rectangular plate-like bottom plate 115, and a front plate 112 separate from the drawer main body 117. This is a structure in which a square frame-shaped side wall portion including three side plate portions 116 and a front plate 112 is provided on the bottom plate 115. The front plate 112 is provided in a state of protruding upward (upward in FIGS. 10A and 10B) from the drawer body 117 in order to hide the clearance.
In addition, the storage case 100 includes a case where the drawer main body 117 is stored in the outer frame 120 so that the mountain-shaped portion 114 of the drawer-side rail 113 of the drawer 110 can get over the mountain-shaped portion riding-up portion 125. The front plate 112 is disposed outside the outer frame 120 (on the left side in FIGS. 10A and 10B, hereinafter referred to as the front side). For this reason, in this storage case 100, the design of the front side portion of the drawer 110 is limited, and the design of the entire storage case 100 is also limited (for example, when the drawer body 117 is stored in the outer frame 120, the front plate 112 is also There was a dissatisfaction that the clearance becomes conspicuous when the structure is housed in the outer frame 120.

(2) The handle 111 of the drawer 110 of the storage case 100 illustrated in FIGS. 10A and 10B is provided at the lower end of the front plate 112. When the handle is the upper end of the front plate 112, the user exerts a downward pressing force on the front plate 112 when the user pulls out the drawer 110 housed in the outer frame 120. Tend. When a downward pressing force is applied to the front plate 112, the mountain-shaped portion 114 of the drawer-side rail 113 in the recess 123 of the outer frame 120 becomes difficult to be detached from the recess 123, so that it becomes difficult to pull out the drawer 110. For this reason, the actual situation is that there is a restriction on the installation position of the handle, and this is also the cause of restrictions on design and design.

(3) In the storage case 100, an operation of pushing the drawer 110 into the outer frame 120, except when the mountain-shaped portion 114 of the drawer-side rail 113 in the recess 123 of the outer frame 120 is detached from the recess 123, and It is desirable that the pull-out operation (here, the movement operation of the drawer 110 when the mountain-shaped portion 114 is positioned on the front side (outside) of the outer frame 120) can be performed with as little force as possible. However, when the mountain-shaped portion 114 is on the front side (outer side) of the outer frame 120, if the distance from the mountain-shaped portion riding portion 125 of the outer frame 120 of the mountain-shaped portion 114 is large, the drawer side of the outer frame 120 with respect to the bottom plate 121. Although the contact range of the rail 113 is small, the contact range of the drawer-side rail 113 with respect to the bottom plate 121 of the outer frame 120 increases as the distance from the mountain-shaped portion riding-up portion 125 of the mountain-shaped portion 114 increases, and the mountain-shaped portion When 114 is in the vicinity of the mountain-shaped portion riding-up portion 125, the bottom side 121 of the outer frame 120 extends over a wide range from the mountain-shaped portion 114 of the drawer side rail 113 to the back side (right side in FIGS. 10A and 10B). Since it is inevitable that the movement resistance of the drawer 110 with respect to the outer frame 120 increases, it is difficult to reduce the movement resistance. Was there was dissatisfaction.
In the point which implement | achieves the stable maintenance of the accommodation state of the drawer | drawer 110 accommodated in the outer frame 120 by the mountain-shaped part 114 of the two drawer side rails 113 fitting in the recessed part 123 of the baseplate 121 of the outer frame 120, Although it is sufficient that at least the peak portion 114 is provided in the drawer 110 and the recess 123 is provided in the bottom plate 121 of the outer frame 120, it is not essential to provide the two drawer side rails 113 in the drawer 110, but the drawer side The rail 113 is useful in that the movement stability of the drawer 110 with respect to the outer frame 120 is ensured by being guided by a guide groove provided in the bottom plate 121 of the outer frame 120, and the rail 113 is stored in the outer frame 120. It is not preferable to omit the drawer-side rail 113 because it effectively contributes to prevention of rattling of the drawer 110.
For this reason, the drawer is provided with two drawer-side rails, and the drawer-like rails are fitted into the recesses of the bottom plate of the outer frame so that the drawer is housed in the outer frame. With respect to the storage case having a configuration capable of realizing stable maintenance, development of a technique capable of reducing the movement resistance of the drawer with respect to the outer frame in a state where the mountain-shaped portion is detached from the recess has been demanded.

  In view of the above problems, the present invention can hide the clearance between the drawer housed in the outer frame and the portion of the outer frame located above the drawer, and can further improve the degree of design freedom. Providing a storage case that can also reduce the resistance of the drawer to the outer frame in a state in which the mountain-shaped portion protruding from the rail-shaped projecting piece of the drawer is separated from the recess formed in the guide groove of the outer frame. It is aimed.

In order to solve the above problems, the present invention provides the following configuration.
A first invention is a storage case comprising an outer frame and a drawer that can be pushed into and pulled out from the outer frame, and the drawer projects downward from the bottom surface of the drawer, Two rail-like projecting pieces extending in parallel from the front side to the rear side provided with handles for performing operations of pushing and pulling out the outer frame with respect to the outer frame are provided. Two guide grooves into which the rail-like protruding pieces of the drawer are inserted extend in the front-rear direction and are formed in parallel to each other, and the depth dimensions of the two guide grooves are the peaks of the rail-like protruding pieces. A recess is formed that is smaller than the protruding dimension from the bottom surface of the drawer, except for the ridge, and on the rear side is fitted with a ridge that protrudes from the lower surface on the rear side of the rail-shaped protruding piece. A storage case is provided.
According to a second aspect of the present invention, there is provided the storage case according to the first aspect, wherein the rail-shaped projecting piece is formed in a tapered shape which tapers from the bottom surface of the drawer toward the projecting tip.
According to a third aspect of the present invention, the rear end of the rail-shaped projecting piece is a tapered portion in which the projecting dimension from the bottom surface of the drawer increases toward the front side of the drawer. The storage case of the invention of 2 is provided.

According to the storage case according to the present invention, since the recessed portion into which the mountain-shaped portion protruding on the lower surface on the rear side of the drawer-like rail-shaped protruding piece is fitted on the rear side of the guide groove of the outer frame is formed. It is not necessary to raise the front end portion of the drawer when the mountain-shaped portion fitted in the concave portion is detached from the concave portion and the drawer in a state of being stored in the outer frame is pulled out from the outer frame. For this reason, the design freedom of the front end portion of the drawer and the entire storage case can be improved. For example, the entire drawer is stored in the outer frame, and the drawer stored in the outer frame and the upper portion of the drawer in the outer frame It is also possible to adopt a configuration that can hide the clearance between the portion located in the position.
In addition, the peak portion of the drawer that is in a state of being separated from the concave portion abuts on the groove bottom of the guide groove of the outer frame, and the front side portion of the drawer rail-shaped protruding piece from the peak portion is the groove bottom of the guide groove. By abutting, the drawer is inclined so that the front side is lower than the rear side, so that the contact range of the rail-shaped protruding piece with respect to the inner surface of the guide groove can be suppressed. Thereby, the movement resistance of the drawer with respect to the outer frame can be reduced.

And it has the structure which has the intermediate | middle bridge | bridging part 21c which bridges between the said pair of cross member parts 21b. The guide groove 26 of the rail portion 21a is formed to extend along the longitudinal direction (extending direction) of the elongated rail portion 21a.

However, the rail unit is not limited to the above-described configuration as long as it has a configuration in which the pair of rail portions in which the guide grooves 26 are formed are provided in parallel to each other. For example, for example, a rectangular frame (not including only the frame-shaped portion) that does not include the intermediate bridge portion 21c, a plurality of intermediate bridge portions 21c, and a bridge between a pair of rail portions. It is also possible to employ one having a lateral bridge.
Moreover, as a rail unit, it is good also as a structure by which a pair of rail part 21a is provided in one plate-shaped member. In this case, the pair of rail portions may be either integrated with the plate member or separate.

On the other hand, as shown in FIGS. 1 and 2, the drawer 30 has four side plate portions 321, 322, 333, and 334 erected in a square frame shape on the outer periphery of a square plate-like bottom plate portion 31. It has a container-like configuration in which the side opposite to the bottom plate portion 31 of the square frame-shaped side wall portion constituted by the portions 321, 322, 333, and 334 is opened (the opening portion 33).
One of the four side plate portions 321, 322, 333, and 334 of the drawer 30 is used by the user of the storage case 10 to manually push the drawer 30 with respect to the outer frame 20 and to perform a drawer operation. A handle 34 is provided. Hereinafter, the side plate portion 321 provided with the handle 34 is also referred to as a front plate portion.

Hereinafter, with respect to the drawer 30, the front plate portion 321 side is referred to as “front side”, and the side plate portion 322 (hereinafter referred to as the rear plate portion) located on the opposite side of the front plate portion 321 through the inner space 30 </ b> S of the drawer 30. The “side” is described as “rear side”. For example, in FIGS. 3A and 3B, the left side is the front side and the right side is the rear side. 3A and 3B, the drawer 30 will be described with the upper side being the upper side and the lower side being the lower side.
Further, the drawer 30 in the illustrated example is an integrally molded product made of synthetic resin. However, the drawer 30 is not limited to this. For example, the drawer 30 may have a structure assembled by a plurality of members, such as a structure in which the front plate portion 321 is a separate member from the bottom plate portion 31.

As shown in FIGS. 2, 3 (a) and 3 (b), the bottom surface 35 of the drawer 30 (the surface opposite to the inner space 30 </ b> S of the bottom plate portion 31. The lower surface) is from the front side to the rear side. Two rail-like projecting pieces 36 extending in parallel with each other are provided so as to project. The rail-shaped projecting piece 36 is a plate-like piece erected on the bottom surface 35.
Further, a mountain-shaped portion 37 protruding in a mountain shape from the lower surface of the rail-shaped protruding piece 36 is formed on the rear side (rear end portion) of the two rail-shaped protruding pieces 36.

3A and 3B, the storage case 10 and the outer frame 20 will be described with the left side being the front, the right side being the rear, the upper side being the upper side, and the lower side being the lower side.
As shown in FIGS. 3A and 3B, the drawer 30 can be inserted and removed from the front side of the outer frame 20 to the inner side of the outer frame 20. In the outer frame 20, the drawer 30 is placed on the pair of rail portions 21 a of the rail unit 21 of the outer frame 20 so as to be surrounded by the rail unit 21, the top plate 23, and the four columns 22. The front plate is aligned in the front-rear direction of the outer frame 20 (the left-right direction in FIGS. 3A and 3B) in the drawer storage portion 24 that is a space (the inner space of the outer frame 20). The part 321 is stored in the front side of the outer frame 20, and the rear plate part 322 is stored in a direction arranged on the rear side of the outer frame 20. The front-rear direction dimension of the outer frame 20 is slightly longer than the front-rear direction dimension of the drawer 30, and the entire drawer 30 can be stored in the drawer storage portion 24 of the outer frame 20.

  As shown in FIG. 4, when the drawer 30 is inserted into the drawer storage portion 24 inside the outer frame 20, the abutment protrusions are provided on both the left and right sides (up and down in FIG. 4) of the front plate portion 321. 38 is formed so as to protrude toward the side of the opposite strut 22a facing each other on a pair of struts 22 (struts indicated by reference numeral 22a) arranged on the front side of the outer frame 20 so as to be separated from each other on the left and right. Further movement to the rear side of the outer frame 20 is restricted by abutting against the protruding protrusion 25 having a protruding wall shape. The position where the abutment protrusion 38 abuts against the stopper projection 25 of the outer frame 20 is the insertion limit position with respect to the outer frame 20 of the drawer 30.

As shown in FIG. 5, in the pair of rail portions 21a of the rail unit 21 of the outer frame 20, two guide grooves 26 into which the rail-like protruding pieces 36 of the drawer 30 are inserted extend in the front-rear direction. Thus, they are formed in parallel to each other.
Further, as shown in FIGS. 3A and 3B, on the rear side (rear end portion) of the guide groove 26, when the drawer 30 is stored in the outer frame 20, the rail-shaped projecting piece 36 is provided. A concave portion 27 into which the mountain-shaped portion 37 is fitted is formed.

6A is a sectional view taken along the line AA in FIG. 3A, and FIG. 6B is a sectional view taken along the line BB in FIG.
As shown in FIG. 6 (a), the two guide grooves 26 have a depth dimension d from the bottom plate portion 31 of the drawer 30 at a portion other than the mountain-shaped portion 37 of the rail-shaped projecting piece 36. It is formed smaller than the projecting dimension t (projecting dimension from the bottom surface 35). In other words, in this storage case 10, the protruding dimension t from the bottom surface 35 of the drawer 30 other than the mountain-shaped portion 37 of the rail-shaped protruding piece 36 of the drawer 30 has a guide of the rail portion 21 a of the rail unit 21. It is larger than the depth dimension d of the groove 26. For this reason, as shown in FIG. 3A, the mountain-shaped portion 37 of the rail-like protruding piece 36 of the drawer 30 housed in the outer frame 20 is fitted in the recess 27 of the guide groove 26 (this The position of the drawer 30 is hereinafter also referred to as a stable storage position), and the drawer 30 is disposed such that the bottom surface 35 thereof is spaced upward from the rail portion 21a of the rail unit 21 of the outer frame 20. The

As shown in FIG. 7A, specifically, the concave portion 27 has an inclination angle θ1 of a front inclined surface 272 that is a front inclined surface from the deepest portion 271 (a portion other than the concave portion 27 of the guide groove 26 (main The inclination angle of the groove portion) with respect to the bottom surface 26a) is an inclination angle θ2 of the rear inclined surface 273 that is the inclined surface on the rear side from the deepest portion 271 (an inclination with respect to the bottom surface 26a of the portion other than the recess 27 of the guide groove 26 (main groove portion)). It is formed in a valley shape larger than (angle).
On the other hand, the mountain-shaped portion 37 of the drawer 30 is formed in a mountain shape corresponding to the concave portion 27 and is fitted into the concave portion 27 as shown in FIG. 7A (the drawer 30 is in the stable storage position). At the same time, the inclined surfaces 372 and 373 on both the front and rear sides from the top 371 contact the inclined surfaces 272 and 273 on the front and rear sides via the deepest portion 271 of the concave portion 27, so that the top portion 371 becomes the deepest of the concave portion 27. Positioned on the portion 271. At this time, the front inclined surface (front inclined surface 372) from the top portion 371 of the mountain-shaped portion 37 comes into contact with the front inclined surface 272 of the concave portion 27 so as to come into surface contact with the rear portion from the top portion 371 of the mountain-shaped portion 37. The inclined surface (rear inclined surface 373) comes into contact with the rear inclined surface 273 of the recess 27 so as to make surface contact.

When the drawer 30 in the state of being pulled out forward of the outer frame 20 is housed in the outer frame 20 by a pushing operation (for example, when the drawer 30 is pushed in slowly without being moved suddenly), the mountain-shaped portion 37 of the drawer 30 is drawn. If the top portion 371 of the concave portion 27 reaches the front inclined surface 272 of the concave portion 27, the mountain-shaped portion 37 is caused to move to the front inclined surface of the concave portion 27 by the weight of the drawer 30 even if the user does not perform further pushing operation. 272 is slid into the recess 27. As a result, the drawer 30 is retracted into the outer frame 20 and stored.
Further, the drawer 30 in the stable storage position can keep the storage state with respect to the outer frame 20 stable as long as the mountain-shaped portion 37 fitted in the recess 27 is not pulled out from the recess 27 to the front side.

  As shown in FIG. 7A, the storage case 10 has a crest of the drawer 30 when the abutment protrusion 38 (see FIG. 4) of the drawer 30 abuts against the stopper projection 25 of the outer frame 20. The shaped portion 37 fits into the recessed portion 27 of the outer frame 20 and the top portion 371 of the mountain-shaped portion 37 is positioned on the deepest portion 271 of the recessed portion 27 so that the drawer 30 is stably stored in the stable storage position. It is configured.

  As described above, as the mountain-shaped portion 37 of the drawer 30, the front inclined surface 372 that can be brought into surface contact with the front inclined surface 272 of the concave portion 27 and the rear side that can be brought into surface contact with the rear inclined surface 273 of the concave portion 27. For example, one or both of the front inclined surface and the rear inclined surface may be a curved surface. Also in this case, as the mountain-shaped portion 37, the top portion 371 of the mountain-shaped portion 37 is the deepest portion of the recessed portion 27 by the contact between the inclined surfaces on both the front and rear sides thereof and the inclined surfaces 272 and 273 on both the front and rear sides of the recessed portion 27. It is formed in a chevron that is positioned on 271.

  As shown in FIG. 3B, when the drawer 30 is located at a position slightly pulled out from the stable storage position to the front of the outer frame 20 with respect to the outer frame 20, the drawer is in a detached state from the recess 27. 30 is in contact with the groove bottom of the guide groove 26 of the outer frame 20 (the bottom surface 26a of the guide groove 26), and the front portion of the rail-shaped protrusion 36 of the drawer 30 is guided from the mountain-shaped portion 37. By contacting the groove bottom of the groove 26, the drawer 30 is inclined (hereinafter also referred to as an inclined state) so that the front side is lower than the rear side. In this inclined state, the rail-shaped projecting piece 36 has a mountain-shaped portion 37 and a position near the contact position with the groove bottom of the guide groove 26 on the rail-shaped projecting piece 36 on the front side of the mountain-shaped portion 37. Only two places serve as contact points with the inner surface of the guide groove 26. Therefore, the contact range of the rail-shaped protruding piece 36 with respect to the inner surface of the guide groove 26 can be reduced.

When the drawer 30 in the state of being pulled out from the front side of the outer frame 20 is pushed into the outer frame 20 and when the drawer 30 is pulled out from the stable storage position, the drawer 30 remains in the inclined state while the above-described state of the outer frame 20 is maintained. By sliding and moving along the rail portion 21a of the rail unit 21, the movement resistance of the drawer 30 relative to the outer frame 20 (specifically, the rail portion 21a of the rail unit 21) can be kept low.
In the storage case 100 having the conventional configuration described with reference to FIGS. 10A and 10B, as described above, in the push-in operation and the pull-out operation of the drawer 110 with respect to the outer frame 120, the mountain of the drawer-side rail 113 is described. The portion on the back side (right side in FIGS. 10A and 10B) from the shape portion 114 contacts the bottom plate 121 of the outer frame 120 over a wide range, and the movement resistance of the drawer 110 with respect to the outer frame 120 increases. However, as described above, the storage case 10 according to the present invention has the rail portion 21a of the rail unit 21 of the outer frame 20 while the drawer 30 is kept inclined in the pushing operation and the pulling operation of the drawer 30 with respect to the outer frame 20 as described above. The rail-like protruding piece 36 of the drawer 30 contacts the inner surface of the guide groove 26 over a wide range. The phenomenon 37 does not occur, and the mountain-shaped portion 37 is detached from the recess 27 in the pushing operation of the drawer 30 pulled out from the outer frame 20 with respect to the outer frame 20 and in the drawer operation of the drawer 30 stored in the outer frame 20. The drawer 30 can be moved with a light force.

  Further, as shown in FIGS. 6A and 6B, the rail-shaped protruding piece 36 (including the mountain-shaped portion 37) protrudes from the bottom plate portion 31 of the drawer 30 (FIGS. 6A and 6B). In b), it is a plate-like piece formed in a tapered shape that tapers toward the lower end). The width W1 (see FIG. 6B) of the tip of the top portion 371 of the mountain-shaped portion 37 of the rail-shaped protruding piece 36 is the above-mentioned mountain shape of the rail-shaped protruding piece 36. It is smaller than the width W2 (see FIG. 6A, the thickness dimension of the rail-like protrusion 36 on the lower surface 362) of the tip surface (hereinafter referred to as the lower surface 362) of a portion other than the portion 37 (hereinafter referred to as the main piece portion 361).

The groove width W26 of the guide groove 26 (see FIG. 6B) is such that when the drawer 30 is in the stable storage position, as shown in FIG. The size is set so that the sticking can be made so that little (or no) sticking occurs.
Therefore, as shown in FIGS. 3 (a) and 6 (a), when the drawer 30 is in the stable storage position, there is little (or no) rattling in the drawer 30 and a stable storage state is obtained. can get.

  On the other hand, as shown in FIGS. 3B and 6B, the mountain-shaped portion 361 in a state of being detached from the concave portion 27 is brought into contact with a portion of the guide groove 26 positioned on the front side of the concave portion 27. When the drawer 30 is in the inclined state, the drawer 30 is inserted into the inner wall surface on both sides in the groove width direction of the guide groove 26 and the guide groove 26 of the rail-shaped projecting piece 36 as compared with when the drawer 30 is in the stable storage position. Since the clearance between the guide groove 26 and the rail-shaped projecting piece 36 is increased, the movement resistance of the drawer 30 can be kept low. This effectively contributes to making the movement in the direction along the longitudinal direction (front-rear direction) of the guide groove 26 of the drawer 30 in an inclined state easy with a light force.

As shown in FIGS. 7B and 7C, the rear end of the rail-shaped projecting piece 36, in other words, the rear end of the mountain-shaped portion 37 moves toward the front side of the drawer 30. The tapered portion 363 has a shape in which the projecting dimension from the bottom plate portion 31 increases.
In the storage case 10, the drawer 30 tilts so that the front end portion of the drawer 30 is on the upper side of the rear end portion when the front plate portion 321 is positioned forward (outside) from the outer frame 20. There is a possibility that when the user pushes or pulls out the drawer 30 with respect to the outer frame 20, the user can tilt the drawer 30 so that the front end portion is higher than the rear end portion. There is. If the rear end of the rail-shaped protruding piece 36 is configured as a tapered portion 363, for example, compared to a configuration in which the rear end of the rail-shaped protruding piece 36 is a right-angled edge instead of the tapered portion 363, Even if the user tilts the drawer 30 so that the front end of the drawer 30 is above the rear end, the guide of the rear end of the rail-shaped protruding piece 36 or the rail unit 21 (specifically, the rail portion 21a) is provided. The inconvenience of damaging or deforming the portion forming the groove 26 and the bottom of the groove is less likely to occur, which is advantageous in terms of long-term stable maintenance of a smooth operation feeling. Further, even if the user tilts the drawer 30 so that the front end portion is on the upper side compared to the rear end portion, the push-in operation and the pull-out operation of the drawer 30 with respect to the outer frame 20 are performed compared to when the user does not tilt. There is little (or no) change in the operation feeling, and a smooth operation feeling can be stably secured against variations in the operation direction of the drawer 30 by the user.

In particular, the rear inclined surface 273 of the concave portion 27 of the guide groove 26 of the outer frame 20 slides the mountain-shaped portion 37 when the drawer 30 is pushed into the outer frame 20, so that the guide groove 26 of the mountain-shaped portion 37 has a sliding shape. This is a portion that facilitates the fitting operation with respect to the concave portion 27 and is a portion where the rear end of the rail-shaped protruding piece 36 is likely to collide when the mountain-shaped portion 37 is fitted into the concave portion 27 of the guide groove 26. In the configuration in which the rear end of the protrusion 36 is a tapered portion 363, the rear inclined surface 273 is damaged or deformed compared to the configuration in which the rear end of the rail-shaped protrusion 36 is a right-angled edge. This is particularly advantageous in terms of preventing this, and it is also effective in maintaining a state in which the fitting operation is performed smoothly over a long period of time.
The tapered portion 363 in the illustrated example is a curved portion having a shape in which the protruding dimension of the drawer 30 from the bottom plate portion 31 increases toward the front side of the drawer 30, so This is particularly preferable from the viewpoint of preventing the rear inclined surface 273 from being damaged or deformed.
However, the present invention includes a configuration in which the rear end of the rail-shaped protruding piece 36 is a right-angled edge.

As shown in FIG. 3A, among the four side plate portions of the drawer 30, between the three side plate portions 322, 323, and 324 excluding the front plate portion 321 and the top plate 23 of the outer frame 20, A clearance C that is large enough to avoid contact with the top plate 23 at the rear end of the inclined drawer 30 is secured.
Further, the front plate portion 321 of the drawer 30 has an upper protruding portion 325 that protrudes above the three side plate portions 322, 323, and 324 in order to hide the clearance C when stored in the outer frame 20. Yes. When the drawer 30 is stored in the outer frame 20, the clearance C is hidden by the upper protrusion 32, and the clearance C does not open on the front side of the storage case 10, so that dust can enter the drawer 30 by the upper protrusion 32. Can be prevented.

According to the storage case 10, when the drawer 30 stored in the outer frame 20 is pulled out from the outer frame 20, the mountain portion 37 fitted in the recess 27 is detached from the recess 27. 10 is a configuration in which a concave portion 27 is formed on the rear side of the guide groove 26 of the outer frame 20 and into which a mountain-shaped portion 37 projecting on the lower surface 362 on the rear side of the rail-shaped protruding piece 36 of the drawer 30 is fitted. There is no need to raise the front end of the drawer 30. For this reason, the design freedom degree of the front-end part of the drawer | drawer 30 and the storage case 10 whole can be improved. As illustrated in FIG. 3A, in the storage case 10, the entire drawer 30 is stored in the outer frame 20, and the drawer 30 and the outer frame 30 are formed by the upper protrusion 325 of the front plate portion 321 of the drawer 30. It is possible to employ a configuration in which the clearance C between the top plate 23 and the top plate 23 is hidden. Even in this configuration, it goes without saying that the drawer 30 can be smoothly pushed into and pulled out from the outer frame 20.
Further, according to the storage case 10, it is possible to reduce the movement resistance when the drawer 30 in the inclined state moves in the longitudinal direction of the guide groove 26 during the push-in operation and the drawer operation of the drawer 30 with respect to the outer frame 20. An excellent effect that 30 can be moved with a light force is obtained.

In addition, this invention is not limited to the above-mentioned embodiment, A design change is possible suitably.
For example, as shown in FIGS. 8 and 9, a drawer 30A having a configuration in which the width dimension of the drawer 30 of the above-described embodiment (the direction perpendicular to the front-rear direction on the upper surface of the bottom plate portion 31) is shorter than the front-rear dimension; A storage case 50 having an elongated outer frame 40 for storing the drawer 30A can also be used.
The outer frame 40 of the storage case 50 is erected on both sides of a rectangular frame-shaped rail unit 41 having a pair of rail portions 41a for guiding the drawer 30A, and the width direction (short direction) of the rail unit 41. A pair of side plates 42, a top plate 43 provided in parallel with the rail unit 41 on the pair of side plates 42, and a back plate 44 erected on one end in the longitudinal direction of the rail unit 41, The rail unit 41 is formed in an elongated shape extending along the longitudinal direction. In the longitudinal direction of the outer frame 40, the end (front end) opposite to the end (back end) where the back plate 44 is provided is an opening 45 for insertion / removal of the drawer 30A.
The rail unit 41 has a rectangular frame shape in which the guide groove 26 is formed and the extending direction (longitudinal direction) of the pair of rail portions 41a extending in parallel with each other is the longitudinal direction. The guide groove 26 extends along the longitudinal direction (extending direction) of the elongated rail portion 21a. As shown in FIG. 9, the concave portion 27 of the guide groove 26 is formed at the back end portion (end portion on the back plate 44 side) of the guide groove 26.
