Description

  The present invention relates to a drawer structure, and more particularly to a drawer structure in which a drawer body is housed in a drawer so as to be freely drawn out by a roller rail.

  15 is a front view showing a drawer state of a conventional drawer structure, FIG. 16 is an enlarged cross-sectional view of the XVI-XVI line shown in FIG. 15, and FIG. 17 is a cross-sectional view of the XVII-XVII line shown in FIG. FIG. 18 is an enlarged end view, and FIG. 18 is an enlarged end view of the XVIII-XVIII line shown in FIG.

  With reference to these drawings, a drawer structure 50 used as a kitchen cabinet includes drawer bodies 60 and 65 aligned vertically, a storage body 70 in which the drawer bodies 60 and 65 are housed, and a drawer body 60. A pair of roller rails 80a and 80b (not shown) are provided between the housing body 70 and allow the drawer body 60 to be pulled out in the drawing direction (left and right direction in FIG. 16) with respect to the housing body 70. . The drawer body 65 is also configured to be freely drawn out from the storage body 70 in the same manner as the drawer body 60.

  The drawer main body 60 has a rectangular door 61 located on the front side on the drawer side (left side in FIG. 16) and a section in the drawer direction having a concave plate shape, and the front surface is connected to the door 61 with screws or the like for storage. A tray 62 extending to the side (right side in FIG. 16), and side plates 63a and 63b (not shown) attached to both ends of the tray 62 in the width direction (left and right direction in FIG. 15) by screws, It is formed in a box shape whose upper surface is open.

  The storage body 70 includes a top plate portion 71 having an IH cooker 75 in which IH cooking portions are arranged in the width direction installed on the upper surface thereof, a bottom plate 72, a side plate 73 a that connects the top plate portion 71 and the bottom plate 72, 73b and a back plate 74 (not shown), and is formed in a box shape whose front surface is open. In addition, since the IH cooker 75 extending in the width direction is installed on the top plate portion 71, the length B in the width direction of the drawer structure 50 shown in FIG. 600 mm, 900 mm, etc.).

  As shown in FIGS. 17 and 18 in particular, the roller rail 80a is attached to the outer surface of the side plate 63a of the drawer body 60 with screws or the like and to the inner surface of the side plate 73a of the storage body 70 with screws or the like. The outer rail 85 is comprised.

  The inner rail 81 extends in the pull-out direction and has a rail section 82 having a cross section in the width direction formed in a substantially inverted L-shaped plate shape, and can be freely rotated via a rotation shaft 83 at the end of the rail section 82 on the storage side. The roller 84 is attached to the roller 84. Note that the upper portion of the rail portion 82 having the inverted L-shaped plate shape is parallel to the axial direction of a rotating shaft 83 (the direction of the dashed line shown on the rotating shaft 87 shown in FIG. 18), and the center portion is turned. It is formed to be perpendicular to the axial direction of the moving shaft 83.

  The outer rail 85 extends along the inner rail 81 in the pull-out direction and has a rail portion 86 formed in a substantially reverse U-shaped cross section in the width direction, and a rotation shaft at the end of the rail portion 86 on the pull-out side. It is comprised from the roller 88 attached rotatably via 87. As shown in FIG. In addition, the upper part and the lower part of the rail part 86 formed in an inverted U-shaped plate shape are parallel to the axial direction of a rotating shaft 87 described later (the direction of the dashed line on the rotating shaft 83 shown in FIG. 17). The central portion is formed to be perpendicular to the axial direction of the rotation shaft 83.

  Each of the inner rail 81 and the outer rail 85 is installed such that the axial directions of the rotation shafts 83 and 87 are horizontal. 17, the upper part of the roller 88 of the outer rail 85 and the upper part of the rail part 82 of the inner rail 81 come into contact with each other, and the upper part of the roller 84 of the inner rail 81 and the outer rail 85 as shown in FIG. The upper part of the rail part 86 is in contact. In addition, gaps 51 and 52 are provided in the width direction between the rollers 84 and 88 and the rail portions 82 and 86, respectively, in order to make the rollers 84 and 88 rotate smoothly. .

  When the drawer body 60 is in the drawer state (the state shown in the figure), the end of the inner rail 81 on the storage side is lifted by a moment about the roller 88 due to the weight of the drawer body 60. Therefore, as described above, the upper portion of the roller 84 of the inner rail 81 and the upper portion of the rail portion 86 of the outer rail 85 abut. On the other hand, when the drawer body 60 is in the retracted state, the moment does not act, so the lower portion of the roller 84 of the inner rail 81 and the lower portion of the rail portion 86 of the outer rail 85 come into contact.

  Since the inner rail 81 and the outer rail 85 are engaged in this manner, the inner rail 81 is slidable in the respective longitudinal directions with respect to the outer rail 85 via the rollers 84 and 88. That is, the drawer body 60 can be pulled out with respect to the storage body 70.

  The roller rail 80b (not shown) is disposed at a symmetrical position with respect to the vertical plane with respect to the roller rail 80a, and each of the inner rail and the outer rail includes a side plate 63b (not shown) of the drawer body 60 and a storage body. It is attached to each of the 70 side plates 73b. The roller rail 80b is a roller rail except that a locking portion 89 (not shown), which will be described later, is formed to prevent the inner rail 81 from moving in the width direction of the roller 84 with respect to the outer rail 85. It is symmetrical with 80a.

  In the conventional drawer structure as described above, a problem may occur when opening and closing the drawer body. This will be described below with reference to the drawings.

  FIG. 19 is a schematic view showing an end face in the width direction of the drawer structure shown in FIG. 15, wherein (1) corresponds to the end face position of FIG. 17, and (2) corresponds to the end face position of FIG. Corresponding.

  Referring to (1) and (2), in the drawer structure 50, as described above, the axial direction of each rotation shaft of the rollers 84 and 88 of the roller rail 80a is the horizontal direction. The upper portions of the rail portions 82 and 86 that are in contact with each other are also installed in the horizontal direction. Further, gaps 51 and 52 are provided in the width direction between each of the rollers 84 and 88 and each of the rail portions 82 and 86. The roller rail 80b is disposed at a symmetrical position with respect to the vertical surface of the roller rail 80a, and has a symmetrical structure except for the engaging portion 89 of the outer rail 85b shown in (2).

  Since the locking portion 89 is formed only on one outer rail 85b, the setting position of the inner rail 81b with respect to the outer rail 85b is stabilized, and the inner rail is connected to the other outer rail 85a corresponding to the setting position. It becomes easy to engage 81a. Therefore, each of the inner rails 81a and 81b can be easily and reliably engaged with each of the outer rails 85a and 85b.

  Here, a problem that occurs when the drawer body 60 is opened and closed will be described.

When opening and closing the drawer body 60, the drawer body 60 is not completely parallel to the longitudinal direction of the roller rails 80a and 80b (through direction in the figure), and the drawer body 60 is pulled slightly obliquely with respect to the longitudinal direction in plan view. May end up. Then, as the component force of the pulling-out force, a force F _{1 in the} width direction indicated by a one-dot chain line arrow in the drawing acts on the pulling main body 60. When the force _{F 1} is applied to the lead body 60, inner rails 81a, 81b will move to the left direction in an amount corresponding diagram of each of the gaps 51 and 52. On the other hand, for example, when the width direction of the force F _2, which is indicated by a dotted arrow in FIG relative to drawer body 60 is applied, the inner rail 81a, 81b is moved to the right direction in an amount corresponding diagram of each of the gaps 51 and 52 End up.

  Thus, when the inner rails 81a and 81b move in the width direction, for example, the flat surface of the roller 88 of the outer rail 85a and the rail portion 82 of the inner rail 81a come into contact with each other. Then, the drawer main body 60 opens and closes while shaking in the width direction due to an impact caused by the contact. For this reason, it becomes difficult to smoothly open and close the drawer main body 60, and in some cases, the rollers 84 and 88 may be removed.

  In addition, when it has an IH cooker in an upper part like a prior art example, it becomes difficult to open and close the drawer main body 60 in parallel with the longitudinal direction of the roller rails 80a and 80b, so that the drawer main body 60 becomes long in the width direction. For this reason, the longer the drawer body 60 is in the width direction, the greater the blur in the width direction of the drawer body 60 during opening and closing, making it difficult to smoothly open and close.

  In order to prevent such a blur in the width direction of the drawer body 60 during opening and closing, there is a method of using a so-called bearing rail that prevents the inner rail from moving in a direction other than the drawer direction. However, since the bearing rail is expensive, it is not preferable in terms of cost.

  The present invention has been made to solve the above-described problems, and provides a drawer structure using a roller rail that prevents a blur in the width direction of the drawer body and exhibits a smooth opening and closing operation. With the goal.

  In order to achieve the above object, the invention according to claim 1 is a drawer structure, which is attached between the drawer body, the storage body in which the drawer body is stored, the drawer body and the storage body, And a pair of roller rails, each of which is arranged symmetrically with respect to the vertical plane, and the axial direction of the rotation shafts of the pair of rollers constituting each roller rail is It is inclined with respect to the horizontal direction.

  If comprised in this way, the movement to the width direction of a drawer | drawing-out main body will always be blocked | prevented by one of the roller rails.

  According to a second aspect of the present invention, in the configuration of the first aspect of the invention, the axial direction of the rotation shaft is located in a direction obliquely upward toward the center of the drawer body.

  If comprised in this way, an inner rail can be set with respect to an outer rail from upper direction.

  According to a third aspect of the present invention, in the configuration of the first or second aspect of the present invention, the axial direction of the rotating shaft is located within a range of 5 to 60 ° with respect to the horizontal direction.

  If comprised in this way, the balance with the movement prevention function to the width direction of a drawer main body and support will improve.

  According to a fourth aspect of the present invention, in the configuration of the invention according to any one of the first to third aspects, the urging means for urging the drawer main body in the pull-out direction is further provided.

  If comprised in this way, a drawer | drawing-out main body will not be laterally shaken also at the time of energizing.

  As described above, according to the first aspect of the present invention, since movement of the drawer body in the width direction is always prevented by one of the roller rails, blurring in the width direction of the drawer body is prevented, resulting in a smooth opening and closing operation. .

  In addition to the effects of the first aspect, the inner rail can be set from above with respect to the outer rail, so that the drawer body can be easily attached to the storage body.

  In addition to the effects of the first or second aspect of the invention, the invention according to the third aspect improves the balance between the movement preventing function in the width direction of the drawer body and the support, thereby realizing a stable drawer operation. To do.

  In addition to the effects of the invention according to any one of claims 1 to 3, the invention according to claim 4 does not cause lateral movement of the drawer body even when energized, so that the automatic drawer operation is stabilized and the usability is improved. To do.

FIG. 3 is a sectional view showing a storage state, FIG. 3 is an enlarged end view of the III-III line shown in FIG. 1, and FIG. 4 is an enlarged end view of the IV-IV line shown in FIG.

  In the description, since it is basically the same as the conventional drawer structure shown in FIG. 15, the difference will be mainly described.

  Referring to these drawings, in the drawer structure 1, the shape of the side plates 63a and 63b (not shown) of the drawer body 60 is different from the shape and arrangement of the roller rails 10a and 10b (not shown). ing. That is, as shown in FIG. 3, a notch 67 whose cut surface is inclined by 45 ° with respect to the horizontal direction is formed at the outer lower end of the side plate 63a of the drawer body 60. The inner rail 11 is attached to the notch 67 with screws or the like, and the outer rail 21 is attached to the inner surface of the side plate 73a of the storage body 70 with screws or the like. The roller rail 10b located on the opposite side of the roller rail 10a in the width direction is arranged in a symmetrical position with respect to the vertical surface of the roller rail 10a and is formed in a symmetrical structure with respect to the vertical surface.

  Here, the detailed shape of the inner rail 11 will be described first.

  5 is a side view of the inner rail shown in FIG. 1 as viewed obliquely from above, FIG. 6 is a view seen from the VI-VI line shown in FIG. 5, and FIG. 7 is a view taken along the line VII- shown in FIG. FIG. 8 is an enlarged sectional view of the VII line, and FIG. 8 is an enlarged sectional view of the VIII-VIII line shown in FIG.

  Referring to these drawings, the inner rail 11 is formed in a substantially inverted L-shaped cross-sectional shape and extends in the pull-out direction (left-right direction in FIG. 5), and the storage side of the rail portion 12 (FIG. 5). And a roller 15 attached to the right side) via a rotating shaft 14. In addition, the upper part in the rail part 12 which has an inverted L-shaped plate shape is parallel to the axial direction of the rotating shaft 14 (the direction of the one-dot chain line on the rotating shaft 14 shown in FIG. 8), and the central part is the rotating shaft. 14 is formed to be perpendicular to the axial direction. Further, a protrusion 17 having a triangular shape in a side view is formed at a position near the storage side in the longitudinal direction in the upper portion of the rail portion 12. Further, a pressing portion 18 for pressing a push latch, which will be described later, is formed at an end of the rail portion 12 on the storage side. The effects of the protrusion 17 and the pressing portion 18 will be described later.

  Next, the detailed shape of the outer rail 21 will be described.

  9 is a side view of the outer rail shown in FIG. 1 as viewed obliquely from above, FIG. 10 is a view as seen from line XX shown in FIG. 9, and FIG. 11 is a view taken along line XI- shown in FIG. FIG. 12 is an enlarged sectional view taken along line XI, and FIG. 12 is an enlarged sectional view taken along line XII-XII shown in FIG.

  Referring to these drawings, the outer rail 21 is formed in an inverted U-shaped cross-sectional shape in which a part of the outer rail 21 protrudes outward, and extends in the pull-out direction (left-right direction in FIG. 9). And a roller 25 attached to the drawer side (left side in FIG. 9) of the rail portion 22 via a rotation shaft 24. In addition, the upper part and the lower part of the rail part 22 are parallel to the axial direction of the rotary shaft 24 (the direction of the alternate long and short dash line on the rotary shaft 24 shown in FIG. 11). It is formed so as to be perpendicular to the axial direction of the rotating shaft 24. Further, as shown in FIG. 11, the virtual plane including the flat surface of the attachment portion 27 to the side plate of the storage body in the rail portion 22 is formed such that the angle θ with respect to the axial direction of the rotating shaft 24 is 45 °. ing.

  Here, referring again to FIGS. 1 to 4, as described above, the inner rail 11 is attached to the notch 67 of the side plate 63 a of the drawer body 60. And since the cut surface of the notch part 67 inclines 45 degrees with respect to a horizontal direction, the upper part of the rail part 12 of the inner rail 11 and the axial direction of the rotating shaft 14 will be in the state inclined 45 degrees. Specifically, the axial direction of the rotation shaft 14 is inclined by 45 ° with respect to the horizontal direction so as to be directed obliquely upward toward the center of the drawer body 60.

  The outer rail 21 has an attachment portion 27 of the rail portion 22 attached to the inner surface of the side plate 73 a of the housing body 70. As described above, the attachment portion 27 of the rail portion 22 is formed to be inclined by 45 ° with respect to the axial direction of the rotation shaft 24. Therefore, by attaching the attachment portion 27 of the rail portion 22 to the side plate 73a, the upper and lower portions of the rail portion 22 of the outer rail 21 and the axial direction of the rotation shaft 24 are inclined by 45 ° with respect to the horizontal direction. . Specifically, like the rotation shaft 14 of the inner rail 11, the axial direction of the rotation shaft 24 is inclined by 45 ° with respect to the horizontal direction so as to go obliquely upward toward the center of the drawer body. It is in a state.

  When the drawer body 60 is in the drawer state, the upper part of the roller 25 of the outer rail 21 and the upper part of the rail part 12 of the inner rail 11 come into contact with each other as shown in FIG. Further, as shown in FIG. 4, the upper portion of the roller 15 of the inner rail 11 and the upper portion of the rail portion 22 of the outer rail 21 come into contact with each other. Further, gaps 19 and 29 are provided between the rollers 15 and 25 in the axial direction of the rotating shafts 14 and 24 and the rail portions 12 and 22 in order to make the rollers 15 and 25 rotate smoothly. Is set to be formed. When the drawer main body 60 is in the retracted state (the state shown in FIG. 2), the moment due to the weight of the drawer main body 60 does not act. Therefore, at the end face position in FIG. The lower part of the rail part 22 of the rail 21 will contact | abut.

  The effects of the roller rails 10a and 10b including the inner rail 11 and the outer rail 21 that are installed and engaged in this way will be described later.

  In the drawer structure 1 according to this embodiment, a push latch 55 as an urging means is installed on the inner rail 11 side of the roller rail 10a. In the housed state shown in FIG. 2, the push latch 55 is in a state in which the urging force is stored by being pressed by the pressing portion of the inner rail 11 described above. Then, when the drawer body 60 is further moved from the storage state to the storage side, a stopper mechanism (not shown) is released, the urging force of the push latch 55 is released, and the drawer body 60 is urged through the inner rail 11 in the drawing direction. Is done. Accordingly, the drawer body 60 automatically moves to the drawer state shown in FIG.

  As shown in FIG. 1, when the drawer main body 60 tries to move further from the drawer state to the drawer side, the protrusion 17 of the inner rail 11 contacts the upper portion of the roller 25 of the outer rail 21. Therefore, excessive protrusion of the drawer body 60 is prevented by the protrusion 17.

  Next, effects of the roller rails 10a and 10b will be described.

  FIG. 13 is a schematic diagram showing an end face in the width direction of the drawer structure shown in FIG. 2, wherein (1) corresponds to the end face position in FIG. 3, and (2) is at the end face position in FIG. (3) corresponds to the end face position in FIG. 4 and shows the case where the drawer structure is in the stored state.

With reference to the drawings, first, an engaged state between each of the inner rails 11a and 11b and each of the outer rails 21a and 21b will be described. At the contact point between each of the inner rails 11a and 11b and each of the outer rails 21a and 21b, the weights W _{1 to} W that are the same as those of the left and right roller rails 10a and 10b at each of the end surface positions (1) to (3). Each of the _three acts. Accordingly, although each of the inner rails 11a and 11b and each of the outer rails 21a and 21b are in contact with each other in an inclined state, since the same weight acts on the roller rails 10a and 10b, they are in a balanced state. . Therefore, each of the inner rails 11a and 11b is stably supported by each of the outer rails 21a and 21b.

Next, Kororeru 10a of the above-described shape and arrangement, in a drawer structure 1 with 10b, with the opening and closing of the drawer body 60, the width direction of the force F ₁ indicated by a one-dot chain line arrow in FIG relative to drawer body 60 The case where it acted is demonstrated.

When the force _{F 1} acts on the drawer body 60, the end in plane position, against movement in the left inner rail 11b of Kororeru 10b, serves roller 25b of the outer rail 21b of stopper (1). That is, since the upper part of the rail part 12b of the inner rail 11b and the upper part of the roller 25b of the outer rail 21b are in contact with each other in an inclined state, when the inner rail 11b tries to move to the left side, at the contact point with the roller 25b. reaction force _{F 1} of the force _{F 1} and the opposite occurs. Therefore, the movement of the inner rail 11b to the left side is prevented. Note that the inner rail 11a located on the left side of the figure is also integrally connected to the inner rail 11b via the drawer body 60, and therefore, movement to the left side is prevented.

On the other hand, in the position of the end face of (2), the roller 15a of the inner rail 11a tends to move to the left, the reaction force F ₁ is generated in the contact point between the upper rail portion 22a of the outer rail 21a, the inner rail 11a Is prevented from moving to the left. Furthermore, in the end surface position of (3), when the roller 15b of the inner rail 11b tends to move to the left, the reaction force F ₁ is generated in the contact point between the lower rail portion 22b of the outer rail 21b, the inner rail 11b Is prevented from moving to the left.

Incidentally, as described above, Kororeru 10a, since 10b are arranged at symmetrical positions with respect to a vertical plane, even when the width direction of the force of the force F ₁ and the opposite direction to the drawer body 60 is applied , as in the case of force F _1, the movement to the right of the drawer body 60 is prevented.

  As described above, in the drawer structure 1 according to this embodiment, the movement of the drawer body 60 in the width direction is always performed by one of the roller rails 10a and 10b regardless of the storage state or the drawer state. Be blocked. Therefore, the drawer main body 60 at the time of opening and closing is completely prevented from shaking in the width direction from the set state, and a smooth opening and closing operation is achieved.

  Further, as described above, the axial directions of the rotation shafts of the rollers 15 a, 15 b, 25 a, 25 b are positioned so as to be directed obliquely upward toward the center of the drawer body 60. Therefore, the distance between the inner rails 11a and 11b in the width direction increases as the distance increases. Therefore, each of the inner rails 11a and 11b can be set from above with respect to each of the outer rails 21a and 21b. Therefore, it becomes easy to attach the drawer body 60 to the storage body 70.

  Furthermore, as described above, the axial direction of each rotation shaft of the rollers 15a, 15b, 25a, 25b is inclined by 45 ° with respect to the horizontal direction. Therefore, the balance between the movement preventing function of the drawer body 60 in the width direction and the support state of the inner rails 11a and 11b by the outer rails 21a and 21b is improved. Therefore, a stable drawer operation is realized.

  Furthermore, as described above, since the push structure as the biasing means is installed in the drawer structure 1, the drawer body 60 is not laterally shaken even when biased in the drawer direction by the push latch. Therefore, the automatic drawer operation of the drawer body 60 is stabilized and the usability is improved.

  FIG. 14 is a schematic view showing an end face in the width direction of the drawer structure according to the second embodiment of the present invention. (1) corresponds to (1) in FIG. 13, and (2) is This corresponds to (2) in FIG.

  In the description, since it is basically the same as the drawer structure according to the first embodiment shown in FIG. 1, the differences will be mainly described.

  With reference to these drawings, in the drawer structure 2 according to this embodiment, the shape of the side plates 63a and 63b of the drawer body 60 is different from the shape and arrangement of the roller rails 30a and 30b. That is, a fixed portion 68 whose surface is inclined by 45 ° with respect to the horizontal direction is formed symmetrically with the notch portion according to the first embodiment at the outer lower end portion of the side plate 63a of the drawer body 60. Yes. The inner rail 31 is attached to the fixed portion 68 with screws or the like, and the outer rail 41 is attached to the inner surface of the side plate 73a of the storage body 70 with screws or the like. In addition, the roller rail 30b located on the opposite side of the roller rail 30a in the width direction is arranged in a symmetrical position with respect to the vertical surface of the roller rail 30a and has a symmetrical structure.

  The inner rail 31 is the same as the inner rail according to the first embodiment, and the rail portion 32 is attached to the fixing portion 68 of the side plate 63 a of the drawer body 60. Accordingly, the axial direction of the rotation shaft of the roller 35 is inclined by 45 ° with respect to the horizontal direction so as to be directed obliquely downward toward the center of the drawer body 60.

  The outer rail 41 is basically the same as the outer rail according to the first embodiment, but the inclined state of the mounting portion 47 of the rail portion 42 is different. In other words, the mounting portion 47 is formed so as to be inclined by 45 ° with respect to the axial direction of the rotating shaft of the roller 45, in contrast to the outer rail according to the first embodiment.

  Then, by attaching such an attachment portion 47 to the side plate 73a of the storage body 70 which is a vertical surface, the axial direction of the rotating shaft of the roller 45 is directed obliquely downward toward the center of the drawer body 60. In addition, the state is inclined by 45 ° with respect to the horizontal direction.

Such Kororeru 30a, In the drawer structure 2 with 30b, when a force _{F 1} in the width direction relative to the drawer body 60 is applied, Kororeru 30a, the reaction force _{F 1} in the contact point of each 30b Occur. That is, the movement of the drawer body 60 in the width direction is always prevented by one of the roller rails 30a and 30b. Therefore, as in the first embodiment, the drawer body 60 is prevented from shaking in the width direction, and a smooth opening / closing operation is achieved.

  Furthermore, as described above, the axial direction of each rotation shaft of the rollers 35 and 45 is inclined by 45 ° with respect to the horizontal direction. Accordingly, as in the first embodiment, the balance between the movement preventing function in the width direction of the drawer body 60 and the support is improved, so that a stable drawer operation is realized.

  In each of the above embodiments, the drawer structure is used as a kitchen cabinet. However, the drawer structure can be similarly applied to other drawer applications such as general furniture and paper storage for a copying machine.

  In each of the above-described embodiments, the drawer main body and the housing body having a specific shape are provided. However, as long as each function can be exhibited, these may have other shapes.

  Furthermore, in each of the above-described embodiments, a pair of roller rails having a specific shape are provided. The roller rails are attached between the drawer main body and the storage body so that the drawer main body can be pulled out with respect to the storage body and each of them is vertical. The pair of roller rails may have other shapes as long as they are arranged symmetrically with respect to the surface and the axial direction of the rotation shafts of the roller pair of roller rails is inclined with respect to the horizontal direction. It does not have to be a completely symmetrical structure. Alternatively, a conventional roller rail may be used while being inclined. In that case, the inner rail and the outer rail may be inclined by attaching each of the inner rail and the outer rail of the conventional roller rail to each of the side plates via a connecting member having a triangular cross section in the width direction, for example.

  Further, in each of the above-described embodiments, the pair of roller rails are attached between each of the side plates of the drawer body and each of the side plates of the storage body. However, the pair of roller rails are, for example, the bottom portion of the drawer body and the storage body. It may be attached between the bottom plate. The term “between the drawer main body and the storage body”, which is a place where a pair of roller rails are used, includes the concept as described above.

  Furthermore, in each of the embodiments described above, the axial direction of the rotation shaft is inclined by 45 ° with respect to the horizontal direction, but in order to improve the balance between the movement preventing function in the width direction of the drawer body and the support, The inclination angle in the axial direction of the rotation shaft is preferably in the range of 5 to 60 ° with respect to the horizontal direction regardless of the direction toward the drawer body. Or as long as the axial direction of the rotating shaft is inclined with respect to the horizontal direction, the angle may exceed the range.

  Further, in each of the above embodiments, a push latch is provided as a biasing means for the drawer body. However, if the drawer body is biased in the pulling direction, the biasing means is other. Also good. Alternatively, the urging means may work in the retracting direction, or there may be no urging means.
