For example, some components may be deleted from all the components shown in this embodiment, or components of different embodiments may be combined as appropriate.

(Packaging container)
As shown in FIG. 1, the packaging container 1 according to the embodiment of the present invention includes a pallet 2 having legs 21 and a body provided on the pallets 2 and having bearing grooves 31 on end wall portions 32 facing each other. A frame 3 and a lid portion 4 provided above the body frame 3 are provided. The bearing groove 31 may further include an upper pressing portion 5 for suppressing the movement of the shaft support portion 11 supported by the bearing groove 31. Each member of the packaging container 1 according to the embodiment of the present invention may be made of a material such as wood or plastic, and is more preferably made of corrugated cardboard.

The object 10 to be stored in the packaging container 1 is a roll-shaped object in which various materials such as metal, plastic, paper, synthetic resin and the like, sheets, foils, strips and the like are wound around the axis 12. If so, it is not particularly limited. In particular, in the present embodiment, the case where the copper foil roll in which the copper foil or the copper alloy foil is wound around the axis 12 is used as the accommodation object 10 will be described, but the present invention is not limited to this.

As shown in FIG. 2, the accommodation object 10 includes shaft support portions 11 projecting from both ends in the axial direction of the axial center 12. By supporting the shaft support portion 11 of the object to be accommodated 10 by the bearing groove 31 of the body frame 3, the object to be accommodated 10 can be suspended in the air and accommodated in the body frame 3. As a result, the influence of external force and gravity applied to the roll portion of the contained object 10 can be reduced, and the deformation of the contained object 10 can be suppressed.

As shown in FIG. 3, the pallet 2 rises from the bottom surface 22 on which the body frame 3 is placed, the bottom surface 22, and is continuous with the pair of end wall portions 23 facing each other and the end wall portions 23, and rises from the bottom surface 22. A pair of side wall portions 24 facing each other and leg portions 21 connected to the bottom surface 22 are provided. By arranging the end wall portion 23 and the side wall portion 24 on the pallet 2, the body frame 3 loaded on the pallet 2 can be accommodated at a predetermined position and the misalignment of the body frame 3 can be suppressed.

As shown in FIG. 4, the leg portion 21 is formed on a laminated body portion 21a in which a plurality of corrugated cardboard plates in which a wavy core is bonded between the liners and the liner are laminated and bonded, and on the laminated body portion 21a. It is provided with a sheet-shaped leg reinforcing portion 21b that is bonded to each other. The laminated body portion 21a is typically composed of 5 to 20 corrugated cardboard plates having a thickness of about 5 to 10 mm in the horizontal direction (vertical direction with respect to the vertical direction) with respect to the bottom surface 22 via an adhesive layer. It has a structure that is laminated to some extent. The leg portion reinforcing portion 21b is attached so as to cover the end surface of the laminated body portion 21a to reinforce the bottom surface of the leg portion 21.

By arranging the leg reinforcing portion 21b on the laminated body portion 21a, the hardness of the bottom surface of the leg portion 21 is increased, and problems during transportation due to damage of the leg portion 21 during transportation and deformation such as dents are prevented. Can be done. The load weight on which the pallet 2 can be loaded and the strength of the leg portion 21 can be adjusted by adjusting the material of the liner and core of the corrugated cardboard plate constituting the laminated body portion 21a, or the number of laminated corrugated cardboard plates.

As shown in FIG. 5, the leg portions 21 are arranged inside (center side) of the end wall portion 23 of the pallet 2 at regular intervals S from the end wall portion 23. This interval S functions as a holding surface 26 for hooking and holding the lifting tool on both ends of the packaging container 1. According to the packaging container 1 according to the present embodiment, the packaging container 1 can be transported more smoothly because the packaging container 1 can be lifted and stably transported by bringing a lifting member such as a rope into contact with the holding surface 26. It becomes possible to do.

Further, if a transport method of lifting and transporting the packaging container 1 can be adopted, it is possible to transport the packaging container 1 packed with heavy objects by a crane or the like even in a facility having a structure in which a forklift or the like cannot be inserted. .. By increasing the choices of the transportation means in this way, the restrictions on the delivery destination facility of the storage object 10 which is the content of the packaging container 1 are relaxed. It can also improve the safety of the work site.

It is preferable that a bottom surface reinforcing portion 25 capable of reinforcing the bottom surface 22 of the pallet 2 is arranged between the legs 21 of the bottom surface 22 of the pallet 2. As a result, the bottom surface 22 of the pallet 2 can be reinforced to suppress the deformation of the packaging container 1 and the strength can be improved. Further, when the packaging container 1 is bound by a binding member 71 such as a band described later, even if the binding force of the binding member 71 is strong enough to sink into the bottom surface reinforcing portion 25, the pallet 2 itself is deformed. Can be suppressed. By bringing the binding member 71 into contact with the bottom surface reinforcing portion 25 and binding the binding member 71 so as to be recessed into the bottom surface reinforcing portion 25, the binding strength can also be improved.

As described above, when a lifting member such as a rope is brought into contact with the holding surface 26 to lift the packaging container 1, a load is applied near the center of the packaging container 1, and as a result, the packaging container 1 may be deformed. In response to such a problem, by providing the bottom surface reinforcing portion 25, it is possible to prevent the packaging container 1 from bending near the center when the packaging container 1 is lifted and transported. When the packaging container 1 is transported by using a forklift or the like, damage to the bottom surface 22 of the pallet 2 can be suppressed even when the claws of the forklift are operated incorrectly.

The arrangement position, shape and thickness of the bottom surface reinforcing portion 25 are not particularly limited and can be variously selected depending on the application. By further arranging the bottom surface reinforcing portion 25 on the holding surface 26, damage to the packaging container 1 during transportation can be further suppressed.

The pallet 2 is provided on the side wall portion 24 with four folding curves RL extending diagonally upward from each of the four corner portions C of the rectangular bottom surface 22 of the pallet 2. The folding curve RL is inclined at an inclination of about 45 degrees with respect to the tangent line L1 between the bottom surface 22 and the side wall portion 24 from the point (corner portion C) where the bottom surface 22, the end wall portion 23, and the side wall portion 24 meet. doing. By folding the folding curve RL into a mountain fold, the pallets 2 can be stacked and stored in a folded state of the end wall portion 23 and the side wall portion 24, so that the storage space before assembling as the packaging container 1 can be reduced. When the packaging container 1 is used, it is only necessary to raise the end wall portion 23 and the side wall portion 24 of the pallet 2, so that the pallet 2 can be easily assembled.

As shown in FIG. 1, the body frame 3 includes a body frame main body 30 and at least one auxiliary frame 34, 35 laminated on the body frame main body 30. By forming the body frame 3 with a plurality of members in this way, it is possible to improve the strength of the body frame main body 30 including the bearing groove 31 provided in the body frame 3. Auxiliary frames 34 and 35 may be omitted.

The body frame main body 30 has a pair of end wall portions 32 facing each other and a pair of side wall portions 33 facing each other, and has a side wall portion 33 between the end wall portions 32 facing each other. The body frame main body 30 has a first bearing groove 310 for supporting the shaft support portion 11 of the accommodation object 10 in the end wall portion 32, respectively.

The body frame body 30 becomes a tubular body as shown in FIG. 1 by connecting two body frame body members 37 as shown in FIG. 7A. The body frame main body member 37 includes an end wall portion 32, a side wall portion 33 continuous with the end wall portion 32, and a joint margin portion 36 formed at the end portion of the end wall portion 32. The body frame body 30 is obtained by connecting the joint portion 36 of one body frame body member 37 to the end portion of the side wall portion 33 of the other body frame body member 37.

The first bearing groove 310 is provided with an accommodating portion 311 capable of accommodating the shaft support portion 11 at the lower end portion and an accommodating portion 313 capable of accommodating the upper pressing portion 5 at the upper end portion. On the side surface of the first bearing groove 310, a locking portion 312 protruding toward the inner center of the first bearing groove 310 is provided in order to abut and support the lower end portion 54 (see FIG. 10) of the upper pressing portion 5. Be prepared. When the bottom portion of the lower end portion 54 of the upper pressing portion 5 and the upper surface of the locking portion 312 come into contact with each other, it is possible to prevent the upper pressing portion 5 from slipping down to the lower side of the first bearing groove 310.

The width W1 of the lower end portion of the first bearing groove 310 in the arc horizontal direction of the first bearing groove 310 has a dimension equivalent to the diameter of the shaft support portion 11 of the accommodation object 10. As a result, the shaft support portion 11 protruding from both ends of the accommodation object 10 can be accommodated in the lower end portion of the first bearing groove 310. The horizontal width W2 of the upper end portion of the first bearing groove 310 is larger than W1 of the lower end portion of the first bearing groove 310. As a result, the shaft support portion 11 of the accommodation object 10 can be easily accommodated in the first bearing groove 310 while preventing the end wall portion 32 of the body frame main body 30 from being damaged.

One or a plurality of reinforcing pads 38, as shown in FIG. 7B, may be attached to the first bearing groove 310 of the body frame body 30 on the end wall portion 32 of the body frame body member 37. As a result, the load bearing capacity of the first bearing groove 310 can be improved.

The reinforcing pad 38 includes a bearing groove 318 having accommodating portions 3118, 3138 and locking portions 3128 having substantially the same shape as the accommodating portions 311 and 313 and the locking portions 312, respectively. Since the bearing groove 318 and the first bearing groove 310 have substantially the same shape, rattling when the shaft support portion 11 is placed can be prevented. On the other hand, since the body frame main body 30 and the reinforcing pad 38 are made of corrugated cardboard, the first bearing groove 310 and the bearing are subjected to the weight of the accommodation object 10 loaded on the bearing groove 318 and the first bearing groove 310 via the shaft support portion 11. Since the groove 318 may be deformed, it may be necessary to provide a certain amount of dimensional allowance. Therefore, the shapes of the first bearing groove 310 of the body frame main body 30 and the bearing groove 318 of the reinforcing pad 38 do not have to have exactly the same shape. The number of layers of the reinforcing pad 38 on the end wall portion 32 can be appropriately adjusted in consideration of the weight of the storage object 10 to be stored and the length of the shaft support portion 11 of the storage object 10.

At least one auxiliary frame 34, 35 is laminated on the body frame main body 30. As shown in FIG. 8A, the auxiliary frame 34 includes an auxiliary side wall portion 334 and a first auxiliary end wall portion 324a and a second auxiliary end wall portion 324b arranged at both ends of the auxiliary side wall portion 334. Be prepared. The first auxiliary end wall portion 324a has a second bearing groove 314a including accommodating portions 3114 and 3134 and locking portions 3124 having substantially the same shape as the first bearing groove 310. The second auxiliary end wall portion 324b includes a transport arm insertion groove 314b in which the width W3 in the arc horizontal direction at the lower end portion is smaller than the arc horizontal width W1 at the lower end portion of the first bearing groove 310.

The auxiliary frame 35 may have the same configuration as the auxiliary frame 34. That is, the auxiliary frame 35 includes an auxiliary side wall portion 335, a first auxiliary end wall portion 325a arranged at both ends of the auxiliary side wall portion 335, and a second auxiliary end wall portion 325b. The first auxiliary end wall portion 325a includes a second bearing groove 315a having a housing portion 3115, 3135 and a locking portion 3125 having substantially the same shape as the first bearing groove 310. The second auxiliary end wall portion 325b includes a transport arm insertion groove 315b whose lower end arc horizontal width W3 is smaller than the lower end arc horizontal width W1 of the first bearing groove 310.

The fact that the width W3 is smaller than the width W1 means that the body frame main body 30, the auxiliary frame 34, and the auxiliary frame 35 are laminated, and the first bearing groove 310 and / or the end wall portion 32 and the first auxiliary end wall portion 325a are provided. When the shaft support portion 11 is placed on the second bearing groove 315a, the outside of the shaft support portion 11 comes into contact with the second auxiliary end wall portion 324b, and the second auxiliary end wall portion 324b is one of the shaft centers 12 of the shaft support portion 11. Cover the portion (see FIG. 8B). As a result, the second auxiliary end wall portion 324b can limit the axial movement of the storage object 10 housed in the packaging container 1. As a result, it is possible to reduce the possibility that the shaft support portion 11 falls off from the bearing groove 31 during the transportation of the packaging container 1 and the contained object 10 falls and is damaged.

The width W3 of the transport arm insertion groove 314b may be smaller than the width W1 to the extent that the axial movement of the accommodation object 10 can be restricted. Among them, in a mode in which the shaft center 12 of the shaft support portion 11 has a hollow structure and the transport arm of the transport device of the object to be accommodated 10 is inserted and transported inside the shaft center 12, the mode will be described later. There are preferred embodiments. For example, assuming that the width W3 is wide enough to allow the transfer arm to be inserted, in the case of a roll-shaped object in which the storage object 10 is wound around an axial center 12 having a hollow shape, when the roll-shaped object is placed in the packaging container 1. , A transport device can be used, and the stored object 10 can be efficiently transported by a machine.

On the first auxiliary end wall portion 324a of the auxiliary frame 34, a reinforcing pad 39a having a transport arm groove 391 having a width W3 substantially the same as that of the second auxiliary end wall portion 324b at the lower end portion may be provided. On the second auxiliary end wall portion 324b of the auxiliary frame 34, a reinforcing pad 39b having a transport arm groove 392 having a width W3 substantially the same as that of the second auxiliary end wall portion 324b at the lower end portion may be provided. Like the auxiliary frame 34, the auxiliary frame 35 can also be provided with reinforcing pads 39a and 39b. As a result, the rigidity of the entire packaging container 1 can be increased, and the strength of the packaging container 1 during suspension and transportation can be ensured. Reinforcing pads 39a and 39b may be omitted if necessary.

When assembling the body frame 3, the second bearing groove 315a and the transport arm insertion groove 314b are stacked on the body frame body 30 in this order on one of the first bearing grooves 310 of the body frame body 30. The first auxiliary end wall portion 325a and the second auxiliary end wall portion 324b are laminated.

FIG. 9 is a top view showing a method of superimposing the body frame main body 30 and the auxiliary frames 34, 35 when the reinforcing pads 39a, 39b are attached to the auxiliary frames 34, 35. Auxiliary frames 34 and 35 are superposed on the outer surface of the body frame body 30 so as to face each other with the body frame body 30 in between.

As shown on the right side of the paper surface of FIG. 9, the first auxiliary end wall portion 325a of the auxiliary frame 35 provided with the second bearing groove 315a is laminated on the outer surface of one end wall portion 32 of the body frame main body 30. NS. A reinforcing pad 39a is attached to the outer surface of the first auxiliary end wall portion 325a, and the second auxiliary end wall portion 324b of the auxiliary frame 34 provided with the transport arm insertion groove 314b is laminated on the outer surface. NS. A reinforcing pad 39b is attached to the outer surface of the second auxiliary end wall portion 324b.

As shown on the left side of the paper surface of FIG. 9, the first auxiliary end wall portion 324a of the auxiliary frame 34 provided with the second bearing groove 314a is laminated on the outer surface of the other end wall portion 32 of the body frame main body 30. NS. A reinforcing pad 39a is attached to the outer surface of the first auxiliary end wall portion 324a, and the second auxiliary end wall portion 325b of the auxiliary frame 35 provided with the transport arm insertion groove 315b is laminated on the outer surface. NS. A reinforcing pad 39b is attached to the outer surface of the second auxiliary end wall portion 325b.

By having such a laminated structure, the shaft support portion 11 on the right side of the paper surface of FIG. 9 is supported by the end wall portion 32 and the first auxiliary end wall portion 325a, and is supported on the outer surface of the first auxiliary end wall portion 325a. The inner surface of the reinforcing pad 39a attached by bonding is substantially in contact with the end surface of the shaft support portion 11 of the accommodation object 10, and suppresses the movement of the shaft support portion 11 in the direction parallel to the axial direction. As a result, it is possible to provide a configuration suitable for suspended transportation while suppressing damage and deformation of the packaging container 1.

The materials constituting the body frame main body 30, auxiliary frames 34, 35 and the reinforcing pads 38, 39a, 39b may be of the same type, but when members having different strengths are used, the first bearing groove 310 may be In order to support the shaft support portion 11 of the accommodation object 10 on the innermost side, it is preferable that the body frame main body 30 is formed of a material having higher strength than the auxiliary frames 34 and 35, more specifically, a material having high compressive strength.

It is preferable that the materials of the auxiliary frames 34 and 35 and the reinforcing pads 38, 39a and 39b are the same as those of the body frame main body 30. On the other hand, the use of a material having high compressive strength may increase the material cost. Therefore, depending on the strength required for the packaging container 1, it may be appropriately selected whether or not the materials of the auxiliary frames 34, 35 and the reinforcing pads 38, 39a, 39b are the same as those of the body frame main body 30.

The bearing groove 31 of the body frame 3 that supports the shaft support portion 11 of the object to be accommodated 10 is affected by the weight of the object to be accommodated 10 and an external force during transportation, and is easily deformed or damaged such as crushed. Therefore, it is preferable that the bearing groove 31 of the body frame 3 is arranged in the vertical direction of the leg portion 21.

When the body frame 3 has a three-layer structure of the body frame main body 30 and the auxiliary frames 34 and 35, the shaft of the object 10 to be accommodated is among the first bearing groove 310 and the second bearing grooves 314a and 315a constituting the bearing groove 31. The first bearing groove 310 of the body frame body 30 that supports the branch 11 on the innermost side may be affected by the weight of the object 10 to be accommodated and an external force during transportation. Therefore, at least the leg portion 21 of the pallet 2 is arranged on the vertical line (upward in the vertical direction) between the first bearing groove 310 of the body frame main body 30 and the innermost contact point between the shaft support portion 11 of the accommodation object 10. As described above, it is preferable to configure the packaging container 1.

As an example of such a configuration, the shaft support portion 11 and the first bearing groove 310 with respect to the leg portion 21 are formed by adjusting the number of the body frame main body 30, the auxiliary frames 34, 35, and the reinforcing pads 38, 39a, 39b. The position of the innermost contact point of is adjusted. As a result, the weight of the accommodation object 10 transmitted from the shaft support portion 11 supported by the bearing groove 31 of the body frame 3 can be supported by the legs 21, so that the accommodation object 10 can be transported even for a long period of time. It is possible to prevent deformation and breakage of the packaging container 1 due to the weight of the packaging container 1.

Further, the auxiliary frames 34 and 35 arranged so as to surround the body frame main body 30 are arranged directly above the holding surface 26 for hooking and holding the lifting tool on both ends of the packaging container 1, thereby having a load bearing capacity. It is possible to support the weight of the object 10 to be accommodated without difficulty, so that a stable transport state can be realized.

During storage, both the tubular body frame main body 30 and the auxiliary frames 34 and 35 can be folded and folded, so that the storage area can be saved. At the time of use, the body frame main body 30, the auxiliary frames 34, and 35 can be assembled and used, so that the packaging container 1 can be stored more efficiently without requiring a large storage space as in the conventional wooden container. can.

As shown in FIG. 10, the upper pressing portion 5 includes a base pad 51 and a guide pad 52 laminated near the central portion of the base pad 51. Below the guide pad 52, a curved surface portion 53 having substantially the same shape as the curved surface of the outer peripheral surface of the shaft support portion 11 of the accommodation object 10 and restricting the vertical movement of the accommodation object 10 during transportation is formed. Since the lower end portion 54 of the upper pressing portion 5 comes into contact with and stops on the locking portion 312 of the body frame main body 30, the upper pressing portion 5 is less likely to be displaced due to vibration during transportation, and the upper pressing portion 5 is stabilized in the accommodating portion 313. Can be accommodated for a long period of time.

The guide pad 52 on the base pad 51 has a structure in which a plurality of corrugated cardboard plates are laminated with an adhesive. It is preferable that the laminated height of the guide pad 52 is adjusted so as to match the thickness of the laminated portion laminated on the end wall portion 32 of the body frame main body 30. By arranging the upper pressing portion 5 in the bearing groove 31 of the body frame 3, it is possible to limit the movement of the accommodation object 10 in the body frame 3 during transportation. Further, by arranging the spacer pad 6 provided with the groove 61 as shown in FIG. 11, the gap between the end face of the accommodation object 10 and the body frame main body 30 is filled, thereby moving the accommodation object 10 in the axial direction. Can be suppressed.

As shown in FIG. 12, the lid portion 4 has a top surface 41 that covers the upper part of the body frame 3 and a part of the side wall portion 33 (auxiliary side wall portion 334, 335) of the body frame 3 that extends downward from the top surface 41. A pair of side wall portions 43 that cover the top surface 41, and a pair of end wall portions 42 that extend downward from the top surface 41 and cover a part of the end wall portions 32 (second auxiliary end wall portions 324b and 325b) of the body frame 3. A top surface reinforcing portion 44 arranged on the top surface 41 is provided. During transportation, a binding member 71 is arranged on the top surface reinforcing portion 44 in order to bind the packaging container 1, but the top surface reinforcing portion 44 is cushioned by the arrangement of the top surface reinforcing portion 44. Since it functions as a material, it is possible to suppress deformation and breakage of the lid portion 4 itself.

Notches 45 that are concave in the central direction are formed at both ends of the top surface reinforcing portion 44. Further, the end wall portion 42 is provided with a protruding portion 46 that projects downward from the tip of the end wall portion 42. The notch 45 and the protrusion 46 are formed so as to have substantially the same shape. Since the cutout portion 45 and the protruding portion 46 have substantially the same shape, as shown in FIG. 13, when the lid portion 4 is bent and folded during storage of the lid portion 4, the cutout portion of the top surface reinforcing portion 44 of the lid portion 4 is formed. Since the 45 and the protruding portion 46 of the end wall portion 42 can be overlapped with each other facing each other, the stacking height when the lid portion 4 is laminated and stored in a folded state can be reduced.

The protrusion 46 has a blindfold function. Since the body frame 3 has a first bearing groove 310, a second bearing groove 314a, 315a and a transfer arm insertion groove 314b, 315b, when packaged as it is, the first bearing groove 310, the second bearing groove 314a, 315a and the transfer arm The insertion grooves 314b and 315b are exposed to the outside. This leads to adhesion of dust to the first bearing groove 310, the second bearing groove 314a, 315a, the transport arm insertion groove 314b, 315b, or the object 10 contained therein, which is not preferable. By providing the protruding portion 46 on the end wall portion 42 of the lid portion 4, the first bearing groove 310, the second bearing groove 314a, 315a and the transport arm insertion groove 314b, 315b are covered, and dust from the outside is prevented from entering. be able to.

The periphery of 1 is bound by a band-shaped binding member 71.

Next, the lifting member for lifting and transporting is brought into contact with the holding surface 26 provided between the end wall portion 23 and the leg portion 21 on the bottom surface 22 of the pallet 2 of the packaging container 1 containing the storage object 10. , The packaging container is lifted, a plurality of packaging containers 1 are laminated, a reinforcing member is arranged on the uppermost packaging container 1, the laminated packaging container is bound by using a band-shaped binding member 71, and this is transported. Transport to the ground.

As described above, according to the packaging container, the packaging method, and the method for transporting the metal foil according to the embodiment of the invention, the leg portions 21 of the pallet 2 are located inside the end wall portion 23 of the pallet 2 at regular intervals. By arranging the S to be vacant, the packaging container 1 can be lifted and transported while the storage object 10 is suspended in the air at an appropriate position. That is, it is possible to take a transport mode other than lifting and transporting the packaging container 1 with the claws of a forklift as in the conventional case, which leads to diversification of transport means and improves transport efficiency.

Further, the end wall portion 32 is formed into a laminated structure by the body frame main body 30 and the auxiliary frames 34 and 35, and the bearing groove 31 of the body frame 3 (the first bearing groove 310 of the body frame main body 30) that supports the gravity of the accommodation object 10 is formed. By arranging the legs 21 on the vertical line of the innermost contact point of the accommodation object 10 with the shaft support portion 11, the weight of the accommodation object 10 transmitted through the bearing groove 31 is transmitted by the legs 21. Since it can be directly supported, it is possible to suppress deformation and damage such as crushing of the packaging container 1 during transportation.

In addition, since the packaging container 1 is made of corrugated cardboard, it can be folded and stored during storage, which saves pace and reduces the weight as compared with the conventional wooden container. Therefore, the transportation means CO ₂ It is also expected to reduce the amount of corrugated cardboard, and it is possible to provide more environmentally friendly packaging containers.

Although the present invention has been described in accordance with the above embodiments, the statements and drawings that form part of this disclosure should not be understood to limit the invention. That is, the present disclosure is not limited to the above-described embodiment, and the components can be modified and embodied without departing from the gist thereof.

In the example shown in FIG. 1, an example in which the body frame 3 is composed of three members of the body frame main body 30 and the auxiliary frames 34 and 35 which are overlapped so as to surround the body frame main body 30 is shown. Is not limited to this example. For example, the auxiliary frames 34 and 35 do not necessarily have to have the auxiliary side wall portions 334 and 335. For example, an auxiliary frame having an auxiliary end wall portion having the same shape as the reinforcing pad 38 is laminated on the end wall portion 32 of the body frame body 30 so as to at least face the end wall portion 32 of the body frame body 30. You may. In the example of FIG. 1, an example in which the auxiliary frames 34 and 35 are arranged on the outside of the body frame main body 30 is described, but it is also possible to arrange the auxiliary frames 34 and 35 on the inside of the body frame main body 30.
