JP 2008-273587 A JP 2004-42932 A

  However, in the pallet of Patent Document 1, the groove forming portion is not provided in the corner portion of the deck, and the four corners of the lower side portion of the sleeve placed on the pallet are in a suspended state. For this reason, the four corners of the sleeve placed on the pallet cannot be supported, and there is a risk of inconvenience such that the standing state of the sleeve cannot be stably maintained.

  On the other hand, the pallet of Patent Document 2 is also provided with a groove forming portion at the corner portion of the deck, and the four corners of the lower side portion of the sleeve can be reliably supported by the groove forming portion. However, the support leg portion provided corresponding to the corner portion of the deck of the pallet in Patent Document 2 is formed in a corner shape so that the surface on the corner portion side of the deck is recessed toward the inner peripheral side of the deck. . For this reason, for example, when a large load is intensively applied from the sleeve or the like to the groove constituting portion at the predetermined corner portion of the deck, there is a problem that the groove constituting portion is deformed. There is concern about inviting. In addition, since the groove forming portion is also formed in the corner portion of the deck, it becomes difficult to insert the sleeve into the groove forming portion, and the workability when the sleeve is erected on the pallet is reduced. There is a fear.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to stably support a sleeve standing on a deck and improve durability in a nestable configuration. It is to provide a pallet that can be used.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A substantially rectangular plate-like deck on which articles are placed;
A plurality of support legs projecting downward at at least four corners of the lower surface of the deck, and supporting the deck, and these are integrally formed pallets,
The support leg portion has a substantially cylindrical shape that opens upward, and an inner side of the support leg portion is formed with a receiving portion that can receive the support leg portion of the pallet stacked on the upper side when the pallets are stacked one above the other. ,
On the upper surface side of the deck, along the outer peripheral edge of the deck, there is formed a groove constituting part for supporting and standing up a square cylindrical sleeve,
The groove constituting portion includes an outer wall portion and an inner wall portion that face each other in the outer peripheral direction of the deck, and a mounting portion that connects between a lower side portion of the outer wall portion and the inner wall portion, and opens upward. ,
In the corner portion of the deck, the support leg portion is formed to bulge toward the outer peripheral side of the deck to a position directly below the mounting portion, and the inner side surface of the support leg portion that is bulged and formed The pallet is characterized in that the inner wall portion of the groove constituting portion is cut out so that the upper surface of the placement portion is continuous (connected).

  According to the means 1, the placing portion for the groove constituting portion is also provided at the corner portion of the deck. For this reason, the four corners of the lower side of the sleeve erected on the pallet can be supported by the mounting portion, and the erected state of the sleeve can be stably maintained. Further, at the corner portion of the deck, the support leg portion is formed to bulge to the position directly below the placement portion toward the outer peripheral side of the deck, and the inside surface of the bulge-formed support leg portion and the placement portion The upper surface is formed continuously (adjacent). For this reason, a support leg part will be extended below from the lower surface of a mounting part, and, thereby, a mounting part can be supported more suitably in the bulging part of a supporting leg part. That is, when the sleeve is placed on the placement portion, the bending moment acting on the placement portion at the corner portion of the deck can be reduced. Therefore, problems such as deformation and breakage of the placement portion can be suppressed, and the support state of the sleeve placed on the placement portion can be stabilized and the durability of the pallet can be improved.

  Moreover, in the site | part in which the support leg part was bulged and formed on the outer peripheral side of the deck, the inner wall part of the groove | channel structure part was notched so that the inner surface of a support leg part and the upper surface of a mounting part might be continued. For this reason, it is possible to avoid a situation in which the inner wall portion has an undercut shape that protrudes to the inner peripheral side of the support leg portion at the portion where the support leg portion bulges to the outer peripheral side of the deck. Therefore, it is possible to reliably mold the inner side surface (accommodating portion) of the support leg portion while suppressing complication of the mold.

  In addition, since the inner wall portion is omitted at the corner portion of the deck, when the sleeve is erected on the deck, the corner portion of the lower side portion of the sleeve can be easily inserted into the groove constituting portion. Can be improved. In particular, in the case where the sleeve is configured to be foldable, such an effect can be achieved more reliably. Further, since the inner wall portion corresponding to the bulging portion of the support leg portion is omitted, when the pallets are stacked up and down, the bulging portion of the support leg portion provided corresponding to the corner portion of the upper pallet Thus, it is possible to avoid a situation in which the inner wall portion adjacent to the lower pallet housing portion interferes. Therefore, the supporting leg portion provided corresponding to the corner portion of the upper pallet can be securely received in the receiving portion of the lower pallet, and as a result, the supporting leg portion bulges to the outer peripheral side of the deck. Even with such a configuration, nesting of pallets can be more reliably performed.

  Mean 2. 2. The pallet according to means 1, wherein the placing section is provided continuously over the entire circumference of the outer peripheral edge of the deck.

  According to the means 2, the entire lower side of the square cylindrical sleeve can be received and supported by the placing portion of the groove constituting portion, and the sleeve placed on the pallet can be stabilized, and the groove constituting portion and the sleeve can be supported.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIGS. 1 to 4, the pallet 1 has a substantially square plate-like deck 2 on which articles are placed, and projects downward from the lower surface of the deck 2, and the upper surface of the deck 2 is set as an installation surface (floor surface). And a supporting leg portion 3 that is supported substantially in parallel. The pallet 1 of this embodiment is integrally formed of polypropylene by molding.

  The support leg 3 includes corner pillars 4 provided at the four corners of the deck 2, an intermediate pillar 5 provided at an intermediate position on the side of the deck 2, and a central pillar 6 ( 2). Each support leg part 3 of this embodiment is comprised by the some cylindrical part, respectively. That is, in this embodiment, the formation range of each support leg 3 is basically divided into square regions of the same size in plan view of the pallet 1 as shown in FIG. The corner column 4 and the intermediate column 5 are configured by two cylindrical portions whose bottom surfaces are substantially rectangular, and the center column 6 is configured by four cylindrical portions whose bottom surfaces are approximately square (FIG. 2). FIG. 4).

  Furthermore, in the present embodiment, for each intermediate column 5, a pair of cylindrical portions are provided so as to be arranged in the outer circumferential direction of the deck 2, and for each corner column 4, a pair of cylindrical shapes of all the corner columns 4. The parts are arranged in the same direction. Hereinafter, for convenience of explanation, a pair of opposite side portions of the deck 2 is referred to as a “first side portion 2a”, and a pair of opposite side portions extending orthogonally to the first side portion 2a is referred to as a “second side”. This will be referred to as “side portion 2b”. In the present embodiment, the pair of cylindrical portions of each corner post 4 are disposed to face each other in the direction along the first side portion 2a. Further, of the pair of cylindrical portions of the corner post 4, the cylindrical portion on the outer peripheral side (second side portion 2 b side) of the deck 2 is referred to as an “outer cylindrical portion 4 a”, and the inner peripheral side ( The cylindrical portion on the first side portion 2a is referred to as “inner cylindrical portion 4b”.

  Moreover, each support leg part 3 (each cylindrical part which comprises each support leg part 3) has comprised the bottomed cylindrical shape opened upwards, and the pallets 1 are piled up and down inside the said support leg part 3. As shown in FIG. In this case, an accommodating portion 8 into which the support leg portion 3 of the pallet 1 stacked on the upper side is inserted is formed. In addition, a gap (fork insertion portion) into which a fork such as a forklift or a handlift (not shown) can be inserted is formed between each corner column 4, intermediate column 5, and center column 6.

  Further, as shown in FIGS. 1, 5, etc., each corner column 4 and the intermediate column 5 are formed with support convex portions 11 that bulge to the inner peripheral side of the corner column 4 or the intermediate column 5. The upper surface of the support convex portion 11 is located slightly above the center position in the height direction of each corner column 4 and intermediate column 5. Moreover, as shown in FIG. 3, the pallet 1 includes a straight line passing through the center portion of the deck 2 and the longitudinal center portion of the first side portion 2a, and the center portion of the deck 2 and the second side portion 2b. Even though it is centered on any straight line passing through the central portion in the longitudinal direction, it is basically configured in a line symmetrical shape (almost the same shape even if rotated 180 degrees around the central portion of the deck 2). The support protrusion 11 is not necessarily provided at a symmetrical position. For this reason, when the pallets 1 are alternately stacked up and down in a direction rotated by 180 degrees, the lower surface of the support leg portion 3 of the upper pallet 1 contacts the upper surface of the support convex portion 11 of the lower pallet 1. It is configured to be supported (stacking is possible).

  On the other hand, when the pallets 1 are stacked in the same direction, the allowable concave portion 12 (see FIGS. 2 and 9) formed on the outer surface side of the support convex portion 11 of the support leg portion 3 of the upper pallet 1 is used. On the other hand, the support protrusion 11 of the lower pallet 1 is inserted, and the height of the stacked pallets 1 is suppressed as compared with the case where the pallets 1 are stacked as described above (nesting is possible). It has become.

  In addition, as shown in FIG. 2, each support leg part 3 has comprised the taper shape which tapers toward the downward direction. Thereby, it is comprised so that it may be easy to perform nesting and stacking of pallets 1 mutually. In addition, a drain hole 13 is formed in the bottom wall of each support leg 3.

  Now, when goods are conveyed using the pallet 1 of this embodiment, as shown in FIGS. 11 and 12, a rectangular cylindrical sleeve 31 is erected on the pallet 1 (deck 2), and further, In some cases, the lid 31 is put on the opening above the sleeve 31 (a box-shaped container is formed). In this case, since the outer periphery of the article placed on the pallet 1 is held by the sleeve 31, the article is prevented from dropping off, and the article placed on the pallet 1 is covered with the sleeve 31 and the lid member 41. Therefore, the article is prevented from being damaged. In FIG. 11, for the sake of convenience, the illustration of the side wall portion of the sleeve 31 on the front side of the drawing is omitted.

  In order to realize this mode, on the upper surface side of the deck 2, as shown in FIG. 1, FIG. 3, and the like, a groove constituting portion 21 for supporting and standing a square cylindrical sleeve 31 is provided on the deck 2. It is formed along the outer periphery. As shown in FIG. 7, FIG. 9, etc., the groove constituting portion 21 extends to the outer peripheral side of the deck 2 from the inner wall portion 22 that extends downward from the outer peripheral edge of the deck 2 and the lower edge portion of the inner wall portion 22. The mounting portion 23 and an outer wall portion 24 extending upward from the front end edge of the mounting portion 23 are provided, and have a substantially U-shaped cross section that opens upward. The width of the placement portion 23 in the outer circumferential direction of the deck 2 (the distance between the opposed outer wall portion 24 and the inner wall portion 22) is slightly wider than the thickness of the sleeve 31 (see FIG. 13). 11 and 12, by inserting the sleeve 31 into the groove constituting portion 21, the lower side portion of the sleeve 31 is supported in contact with the upper surface of the placement portion 23, and the outer wall portion 24 and The inner wall portion 22 prevents the sleeve 31 from being displaced in the horizontal direction.

And slightly inclined toward the inner peripheral side of the deck 2.

  As shown in FIGS. 5 to 8, etc., in the present embodiment, the deck 2 has an outer cylindrical portion 4 a of the corner post 4 provided corresponding to the corner portion of the deck 2 in the support leg portion 3. A bulging portion 27 that bulges to a position directly below the mounting portion 23 of the groove constituting portion 21 is formed. As shown in FIGS. 6 and 10, the bulging portion 27 is configured to extend downward from the lower surface of the mounting portion 23 at a position on the outer peripheral side of the deck 2 relative to the inner wall portion 22. Further, as shown in FIG. 10 and the like, the inner wall portion 22 corresponding to the bulging portion 27 is formed so that the inner surface of the bulging portion 27 and the upper surface of the placement portion 23 are continuous (connected). Notched (omitted). Therefore, the bulging portion 27 extends downward from the lower surface of the placement portion 23 along the edge of the placement portion 23 on the inner peripheral side of the deck 2.

  On the other hand, the mounting portion 23 and the outer wall portion 24 of the groove constituting portion 21 are continuously provided over the entire circumference of the outer peripheral edge of the deck 2 (see FIGS. 1 and 3). Furthermore, as shown in FIG. 10 and the like, the width of the mounting portion 23 is substantially the same in both the portion connected to the bulging portion 27 and other general portions.

  In the present embodiment, the bulging portion 27 is provided only on the outer cylindrical portion 4 a of the corner post 4, and even if it is the support leg portion 3 provided along the outer peripheral edge of the deck 2, the intermediate post 5 is provided. It is not formed on the inner cylindrical portion 4 b of the corner post 4. Furthermore, the bulging portion 27 does not bulge the outer cylindrical portion 4a as a whole on the outer peripheral side of the deck 2, but bends in an L shape along the groove constituting portion 21 of the outer cylindrical portion 4a. The wall portion is provided in a part including the bent portion of the wall portion bent in an L shape so that the portion connected to the inner wall portion 22 is left on both side portions. In addition, with respect to the portions other than the bulging portion 27 of the intermediate pillar 5, the inner cylindrical portion 4 b, and the outer cylindrical portion 4 a, the groove constituting portion 21 ( It is provided on the inner peripheral side of the deck 2 with respect to the inner wall portion 22).

  Further, as shown in FIGS. 11 and 12, the sleeve 31 of the present embodiment includes four side wall portions 32 to form a square tube shape, and the side wall portions 32 are bendable via hinge portions (not shown). It is connected. Further, a pair of opposing side wall portions 32 among the four side wall portions 32 is configured by two plate-like bodies 33 arranged on the left and right sides being flexibly connected by a hinge portion (not shown). With this configuration, the sleeve 31 can be folded so that the side wall portion 32 formed by the two plate-like bodies 33 is folded inward.

  Further, as shown in FIG. 2, reinforcing ribs 15 extending in a lattice shape are formed on the lower surface side of the deck 2. Further, as shown in FIG. 13, a locking member that can protrude inward of the groove constituting portion 21 is provided at a portion between each corner column 4 and the intermediate column 5 arranged along the first side portion 2 a of the deck 2. 17 is provided so as to be slidable in the outer peripheral direction of the deck 2. On the other hand, a locking hole 37 penetrating in the thickness direction of the sleeve 31 is formed in a portion of the sleeve 31 to be inserted inside the groove constituting portion 21. Then, as shown in FIG. 14, with the sleeve 31 inserted in the groove constituting portion 21, the lock member 17 protrudes into the groove constituting portion 21, so that the tip of the lock member 17 is engaged with the locking hole of the sleeve 31. 37 is inserted. As a result, the sleeve 31 can be more reliably prevented from falling off.

  As described in detail above, according to the present embodiment, the mounting portion 23 of the groove constituting portion 21 is provided also in the corner portion of the deck 2. For this reason, the four corners of the lower side portion of the sleeve 31 erected on the pallet 1 can be supported by the mounting portion 23, and the erected state of the sleeve 31 can be stably maintained. In addition, a bulging portion 27 that bulges to a position directly below the mounting portion 23 toward the outer peripheral side of the deck 2 is provided on the support leg portion 3 (corner column 4) provided corresponding to the corner portion of the deck 2. In addition to being formed, the inner surface of the bulging portion 27 and the upper surface of the placement portion 23 are formed continuously (adjacent). For this reason, the bulging part 27 of the corner post 4 extends downward from the lower surface of the mounting part 23, whereby the mounting part 23 can be more suitably supported by the bulging part 27. That is, when the sleeve 31 is placed on the placement portion 23, the bending moment acting on the placement portion 23 at the corner portion of the deck 2 can be reduced. Accordingly, problems such as deformation and breakage of the placement portion 23 can be suppressed, and the support state of the sleeve 31 placed on the placement portion 23 can be stabilized, and the durability of the pallet 1 can be improved. Can do.

  Moreover, in the formation site | part of the bulging part 27, the inner wall part 22 of the groove | channel structure part 21 is notched so that the inner surface of the bulging part 27 and the upper surface of the mounting part 23 may be continued. For this reason, it is possible to avoid a situation in which the inner wall portion 22 has an undercut shape that protrudes toward the inner peripheral side of the corner post 4 at the site where the bulging portion 27 is formed. Therefore, the inner side surface (accommodating portion 8) of the corner post 4 can be reliably molded while suppressing the complication of the mold.

  In addition, since the inner wall portion 22 is omitted at the corner portion of the deck 2, when the sleeve 31 is erected on the deck 2, the corner portion of the lower side portion of the sleeve 31 is easily inserted into the groove constituting portion 21. And workability can be improved. In particular, in the case where the sleeve 31 is configured to be foldable, this effect can be achieved more reliably. Further, since the inner wall portion 22 corresponding to the site where the bulging portion 27 is formed is omitted, when the pallet 1 is stacked up and down, the support leg portion 3 provided corresponding to the corner portion of the upper pallet 1. Can be reliably accommodated in the corresponding accommodating portion of the lower pallet. Accordingly, nesting of pallets can be more reliably performed even when the support leg portion is configured to bulge to the outer peripheral side of the deck.

  In addition, since the inner wall portion 22 is omitted at the corner portion of the deck 2, when the sleeve 31 is erected on the deck 2, the corner portion of the lower side portion of the sleeve 31 is easily inserted into the groove constituting portion 21. And workability can be improved. In particular, in the case where the sleeve 31 is configured to be foldable, this effect can be achieved more reliably. Further, since the inner wall portion 22 corresponding to the bulging portion 27 is omitted, when the pallets 1 are stacked up and down, the bulging portion 27 of the upper pallet 1 and the accommodating portion 8 of the lower pallet 1 are stored. It is possible to avoid a situation in which the inner wall portion 22 adjacent to is interfered. Therefore, the corner post 4 of the upper pallet 1 can be securely stored in the storage portion 8 of the lower pallet 1, and as a result, the bulging portion 27 is formed in the corner post 4. However, the nesting of the pallets 1 can be performed more reliably.

  In addition, the placement portion 23 of the groove constituting portion 21 is continuously provided over the entire circumference of the outer peripheral edge of the deck 2. For this reason, the entire lower side portion of the rectangular cylindrical sleeve 31 can be received and supported by the mounting portion 23 of the groove constituting portion 21, and the sleeve 31 placed on the pallet 1 can be stabilized or the groove constituting portion 21 can be supported. Further, the durability of the sleeve 31 can be improved. In addition, the inner wall portion 22 has a portion corresponding to the bulging portion 27 and is provided continuously at other portions. For this reason, while being able to prevent the position shift of the side wall part 32 of the sleeve 31 more reliably, the situation where the sleeve 31 will be folded carelessly can be prevented.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above-described embodiment, a part of the outer cylindrical portion 4a of the corner post 4 bulges out at a part of the portion extending in the L shape along the corner portion of the deck 2 (the portion adjacent to the groove constituting portion 21). Although the portion 27 is formed and the inner wall portion 22 in the range corresponding to the bulging portion 27 is omitted, for example, as shown in FIG. 15, at the corner portion of the deck 2 of the outer cylindrical portion 4a of the corner post 4 You may abbreviate | omit the inner wall part 22 in the whole site | part extended in L shape along. In this case, as shown in the figure, the omitted portion of the inner wall portion 22 may not correspond to the formation range of the bulging portion 27, or the forming range of the bulging portion 27 may not correspond to the omitted portion of the inner wall portion 22. You may make it correspond. Further, as shown in FIG. 15, the inner wall portion 22 is omitted so that the inner surface of the inner cylindrical portion 4 b and the upper surface of the mounting portion 23 of the groove forming portion 21 are continuous, or the inner surface of the intermediate column 5 is omitted. Alternatively, the inner wall portion 22 may be omitted so that the upper surface of the mounting portion 23 is continuous.

  (B) In the above embodiment, the width of the mounting portion 23 of the groove constituting portion 21 is configured to be slightly larger than the thickness of the sleeve 31, but the width of the groove constituting portion 21 is not particularly limited. It may be larger than the above embodiment. However, from the viewpoint of positioning the sleeve 31 (preventing displacement in the horizontal direction), it is desirable that the sleeve 31 be configured as narrow as possible (a little larger than the thickness of the sleeve 31).

  Further, the width of the mounting portion 23 is set to the thickness of the sleeve 31 (side wall portion 32) so that the four corners of the lower side portion of the sleeve 31 are securely mounted just above the bulging portion 27 of the corner post 4. It is desirable to make it shorter than the length obtained by adding the thickness of the wall portion constituting the support leg portion 3. Further, the inner dimension of the sleeve 31 and the outer dimension of the inner wall portion 22 extending in a substantially frame shape are substantially the same (the inner surface of a predetermined side wall portion of the sleeve 31 and the outer surface of the corresponding inner wall portion 22 are in contact with each other. In some cases, the distance between the inner surface of the side wall portion facing the predetermined side wall portion and the outer surface of the corresponding inner wall portion 22 is equal to or less than the thickness of the bulging portion 27). Therefore, the same effect can be obtained.

  Furthermore, in the said embodiment, although the width | variety of the mounting part 23 is constant over a perimeter, you may differ for every part. For example, you may comprise so that the site | part corresponding to the corner part of the deck 2 may become narrower than another site | part. In this case, the bulging portion 27 of the corner post 4 can be further bulged toward the outer peripheral side of the deck 2, and the sleeve 31 can be more suitably supported by the bulging portion 27.

  Moreover, the mounting part 23 of the groove | channel structure part 21 does not need to be continuously formed over the perimeter along the outer periphery of the deck 2, and the site | part which may interrupt may exist. However, it is assumed that the placing portion 23 is formed at least at the corner portion of the deck 2, and further, it continues along the entire outer peripheral edge of the deck 2 in order to stabilize the support state of the sleeve 31. It is desirable to be provided. Furthermore, the outer wall portion 24 may not be continuously formed along the outer peripheral edge of the deck 2 and may be interrupted. In addition, not only a portion corresponding to the bulging portion 27 may be formed on the inner wall portion 22 as well. In the above-described embodiment, the deck 2 has a substantially square shape in plan view, but may have a substantially rectangular plate shape.

  (C) In the said embodiment, as shown in FIG. 9, the inner wall part 22 which comprises the groove structure part 21, and the wall part which comprises the support leg part 3 (the corner pillar 4 and the intermediate pillar 5) are comprised separately. However, it may be shared as shown in FIG. Also in this case, as shown in FIG. 16 (b), the support leg portion 3 (corner column 4) bulges outward corresponding to the corner portion of the deck 2 to form the bulging portion 27, and the inner wall portion 22. By omitting, effects similar to those of the above embodiment can be obtained. In this case, the common wall portion (inner wall portion 22) extends in a substantially vertical direction so as not to have an undercut shape, and is accommodated so that the support leg portion 3 can be easily inserted into the accommodation portion 8 during nesting or the like. It is desirable to incline the outer surface of the deck 2 with the surface constituting the portion 8 facing upward. Further, in order to make it easier to insert the sleeve 31 into the groove constituting portion 21, the surface constituting the groove constituting portion 21 is inclined upward toward the inner peripheral side of the deck 2 (the inner wall portion 22 is gradually directed upward). It is more preferable that the cross section is tapered so as to be thin.

  (D) In the above embodiment, the number of support legs 3 is not particularly limited, and it is only necessary that corner pillars 4 corresponding to at least four corners of the deck 2 are provided. Moreover, in the said embodiment, although each support leg part 3 (the corner pillar 4, the intermediate | middle pillar 5, the center pillar 6) is respectively comprised by the some cylindrical part, even if each is comprised by one cylindrical part, Good. In addition, you may abbreviate | omit the support convex part 11 in the said embodiment. Even in this case, the pallet 1 can be nested.

  Moreover, in the said embodiment, you may abbreviate | omit the drain hole 13 formed in the bottom wall of each support leg part 3. FIG. In the case where an assembly-type container is formed by standing the sleeve 31 on the pallet 1 and covering the lid member 41, for example, when rainwater or the like is applied to the assembly-type container, the rainwater travels through the sleeve 31 to form a groove. In the above-described embodiment, the upper surface of the mounting portion 23 of the groove forming portion 21 and the inner side surface of the bulging portion 27 of the corner post 4 are connected in the corner portion of the deck 2. Since the groove constituting portion 21 and the accommodating portion 8 of the corner post 4 communicate with each other, the rainwater that has entered the groove constituting portion 21 is inside the bulging portion 27 of the corner post 4 (the accommodating portion 8). ) Through the drain hole 13 in the bottom wall of the corner post 4.

  (E) In the above embodiment, the locking hole 37 for locking the tip of the locking member 17 is formed in the lower part of the sleeve 31, but the configuration for fixing the lower part of the sleeve 31 to the pallet 1 is particularly limited. It is not something.
