Description

[Technical Field]

[0001] The present disclosure relates to a load retention device and a load movement restriction method. [Background technology]

[0002] A technique for fastening cargo inside a container using a locking ring provided inside the container is known (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2016-074472 Summary of the Invention [Problem to be solved by the invention]

[0004] Some containers do not have the locking rings. Furthermore, because the locking rings are fixed at several fixed locations within the container, the ends of the belts used to secure the cargo are positioned at these fixed locations, limiting the flexibility of how the cargo is secured, and sometimes preventing the cargo from being securely secured. Furthermore, installing a large-scale device inside the container reduces the efficiency of the lashing work.

[0005] In view of the above circumstances, there is a need for a cargo retention device and a method for restricting cargo movement that can improve the flexibility of how cargo is secured within a container while also improving the ease of securing the cargo. [Means for solving the problem]

[0006] A first aspect of the present disclosure is a cargo retention device capable of restricting the movement of cargo inside a container in the longitudinal direction of the container, comprising a beam member attached to the interior of the container by pressing one end and the other end against a pair of walls aligned in the width direction of the container, and a flexible fastening member having a first end and a second end attached to the beam member, and retaining the cargo surrounded by the beam member and the fastening member having the first end and the second end attached to the beam member.

[0007] A second aspect of the present disclosure is a method for restricting cargo movement inside a container, capable of restricting the movement of cargo in the longitudinal direction of the container, comprising: attaching a beam member to the interior of the container by pressing one end and the other end of the beam member against a pair of walls aligned in the width direction of the container; and holding the cargo surrounded by the beam member and the fastening member by attaching first and second ends of a flexible fastening member to the beam member.

[0009] A load retaining device 1 according to one embodiment will be described below with reference to the drawings. The cargo retaining device 1 of this embodiment is attached to a container 10 as shown in Figures 1 to 4. As shown in Figure 1, the container 10 has a longitudinal direction that is a substantially horizontal direction, a width direction that is a substantially horizontal direction perpendicular to the longitudinal direction, and a vertical direction that is a substantially vertical direction. The width direction can also be said to be the extension direction of beam members 20 and beam bodies 24 attached to the container 10 as described below.

[0010] As shown in Figures 1 to 3, the container 10 has walls 12 on both sides of its width, each wall 12 having a corrugated shape. In other words, each wall 12 has an uneven shape. In one example, the thickness of the plate members constituting each wall 12 is several millimeters. Therefore, each wall 12 has a plurality of convex portions 12A spaced apart along the longitudinal direction of the container 10, each extending vertically. Each convex portion 12A protrudes toward the inside of the container 10. Between two adjacent convex portions 12A, a concave portion 12B extending vertically is formed. As shown in Figure 5, the concave portion 12B has a pair of sloped portions 12D and a bottom portion 12C, and can be said to have a groove shape extending vertically. The container 10 has a wall 13 at one longitudinal end, a wall (not shown) at the other longitudinal end having, for example, a door, a floor plate 14, and a top plate (not shown). The load retaining device 1 may also be used with containers 10 of other specifications.

[0011] The containers 10 in circulation do not have owners and are used by various people, companies, etc. For this reason, a container 10 that has been used once is often used again by another person, another company, etc.

[0012] The cargo holding device 1 of this embodiment is capable of restricting movement of cargo 100 in the longitudinal direction of the container 10 inside 11 of such a container 10. The cargo holding device 1 has a beam member 20 that is attached to the interior 11 of the container 10 by having one end and the other end pressed against a pair of walls 12 aligned in the width direction of the container 10. As shown in Figures 6 to 8, the beam member 20 has a beam main body 24 that is tubular, such as a rectangular cylindrical shape, or tubular, or that has a pipe shape. It is possible to use other members that are long in the width direction as the beam member 20.

[0013] For example, the beam body 24 is formed by extrusion molding of aluminum. Furthermore, as shown in FIGS. 6 to 8, the beam member 20 has pressing portions 25 attached to both ends of the beam body 24, and each pressing portion 25 has a pressing surface 26 facing the wall 12. In this embodiment, the pressing surface 26 is configured to be pressed against the recess 12B via a buffer member 27 (FIGS. 5 and 9) made of a material with rubber-like elasticity. The pressing surface 26 has a shape that conforms to the recess 12B and is slightly smaller than the recess 12B. As shown in FIG. 5, the pressing surface 26 has a planar top surface 26A that extends in the longitudinal direction along the bottom 12C of the recess 12B, and a pair of planar inclined surfaces 26B that are disposed on both sides of the top surface 26A in the longitudinal direction and extend along the pair of inclined surfaces 12D of the recess 12B, respectively.

[0014] Examples of materials having rubber-like elasticity that can be used include rubber, urethane, and urethane foam. The buffer member 27 has a sheet shape with a thickness of, for example, several millimeters, and is fixed to the pressing surface 26 with an adhesive or the like. In this embodiment, the buffer member 27 is fixed to the top surface 26A and the pair of inclined surfaces 26B, respectively. In another aspect, the entire pressing surface 26 or the entire pressing portion 25 may be covered with the buffer member 27. This configuration has the effects of preventing damage to the container 10 due to a collision of the pressing surface 26 or the pressing portion 25, preventing rust on the pressing surface 26 or the pressing portion 25, and the like.

[0015] In this embodiment, one pressing portion 25 is attached to one end of the beam body 24 so as to be movable in the extension direction of the beam body 24, and the other pressing portion 25 is fixed to the other end of the beam body 24, for example, by bolting, welding, etc. The other pressing portion 25 may be fixed to the other end of the beam body 24 by another method, or the other pressing portion 25 may be movable in the extension direction of the beam body 24 like the one pressing portion 25.

[0016] 9, the base end side of a movable member 40 such as a shaft extending in the width direction is fixed to one of the pressing portions 25, and a holding mechanism 50 for holding the movable member 40 is provided at one end of the beam body 24. In this embodiment, the base end side of the movable member 40 is attached to the pressing portion 25 so as not to move in the extension direction. The movable member 40 may rotate around its central axis relative to the pressing portion 25.

[0017] 9, the holding mechanism 50 has an inner member 51 fixed to the inner circumferential surface of one end side of the beam main body 24, and an outer member 52 fixed to the outer circumferential surface of one end side of the beam main body 24. The inner member 51 has a hole 51A through which the tip side of the movable member 40 is inserted. The inner member 51 may be any member that can support the tip side of the movable member 40 in the longitudinal direction and the up-down direction.

[0018] The outer member 52 has a hole 52A through which an intermediate position of the movable member 40, which is a position between the pressing portion 25 and the hole 51A, is inserted. The inner member 51 may be any member that can support the intermediate position in the longitudinal direction and the vertical direction. In another example, a part of the pressing portion 25 may be supported by the outer member 52 in the longitudinal direction and the vertical direction instead of the intermediate position. In yet another example, instead of the outer member 52, a part of the beam member 20, such as one end side of the beam main body 24, may perform the same function as the hole 52A.

[0019] In this embodiment, the inner member 51 is formed by cutting, bending, drilling, etc., from a metal plate material, and has a substantially U-shape. The side wall portion of the inner member 51 contacts the inner peripheral surface of one end of the beam main body 24, and a hole 51A is formed in the bottom surface portion of the inner member 51. This configuration contributes to the effect of reducing the weight of the beam member 20 while ensuring that a large force, described below, applied to the beam member 20 is received by the movable member 40 and the pressing portion 25.

[0020] In this embodiment, the outer member 52 is formed by cutting, bending, drilling, etc., from a metal plate material, and has a substantially U-shape. The side wall portion of the outer member 52 contacts the outer peripheral surface of one end of the beam main body 24, and a hole 52A is formed in the bottom surface portion of the outer member 52. This configuration contributes to the effect of reducing the weight of the beam member 20 while ensuring that a large force applied to the beam member 20 is received by the movable member 40 and the pressing portion 25.

[0021] 6, 9, etc., the side walls of the inner member 51 and the outer member 52 are fixed to the beam body 24 by bolts 53 extending in the longitudinal direction. Two bolts 53 may be arranged so as to contact both the upper and lower sides of the movable member 40, and this configuration can contribute to the effect of ensuring that large forces applied to the beam member 20 are received by the movable member 40 and the pressing portion 25.

[0022] As shown in FIGS. 8 and 9 , the beam member 20 is provided with a pressing adjustment mechanism 28. The pressing adjustment mechanism 28 of this embodiment has a male threaded portion 28A provided on the outer peripheral surface of the movable member 40 and a rotating member 28B that screws into the male threaded portion 28A. The rotating member 28B of this embodiment is a plate with a through hole, and the through hole is provided with a female thread. The rotating member 28B is disposed between the pressing portion 25 and the outer member 52, and the rotating member 28B contacts the beam main body 24 from the outside in the width direction, or the rotating member 28B contacts the outer member 52 in the same direction. Therefore, by rotating the rotating member 28B, the pressing portion 25 moves in the width direction away from the beam main body 24.

[0023] A female screw member such as a nut may be threaded onto the male screw portion 28A between the pressing portion 25 and the rotating member 28B, and the female screw member may be able to come into contact with the rotating member 28B. Alternatively, a restriction mechanism may be provided on the end side of the beam main body 24 to restrict rotation of the rotating member 28B so that the rotating member 28B does not rotate around the movable member 40. The restriction mechanism may be, for example, a retractable member that retracts from the end side of the beam main body 24 in the extension direction of the beam main body 24, and a hole provided in the rotating member 28B into which the retractable member is inserted. The restriction mechanism and the female screw member function as a rotation restriction means that restricts the rotation of the rotating member 28B. Note that, as the pressing adjustment mechanism 28, it is also possible to use other mechanisms that can press the pressing portion 25 against the wall 12.

[0024] As shown in FIG. 6 and other figures, metal mounting portions 23 are attached to one end and the other end of beam member 20. Specifically, one end of a pair of flexible connecting members 23A is fixed to one end and the other end of beam member 20, respectively, and mounting portions 23, such as a metal ring, are attached to the other end of connecting member 23A. In this embodiment, connecting member 23A is a belt-shaped member such as a belt made of synthetic fiber, but other flexible members can also be used. This allows mounting portions 23 to move flexibly relative to beam member 20. Note that, as shown in FIG. 6, if the width direction of the belt-shaped member at one end of connecting member 23A extends vertically, the vertical position of mounting portions 23 is more likely to be stable. This contributes to facilitating the work described below, and this effect is useful.

[0025] As shown in FIG. 6 and other figures, in the attachment portion 23 of this embodiment, the opening of the metal ring is widest on the side of the connecting member 23A and gradually narrows as it moves away from the connecting member 23A. The opening of the metal ring can also be described as being mountain-shaped, approximately triangular, or drop-shaped. This configuration has the effect of ensuring that the first end 61 or the second end 62 stably contacts the metal ring at a position on the metal ring that is away from the connecting member 23A when the lashing member 60 lashes the luggage 100, as described below. In this embodiment, the lashing member 60 is a belt-like member such as a synthetic fiber belt. However, other flexible members can also be used, as long as the lashing member 60 has the flexibility to flex along the luggage 100 or other object.

[0026] As shown in FIG. 2 etc., the cargo retaining device 1 of this embodiment has two or more positioning members 70. In one example, a pair of positioning members 70 is provided for one beam member 20. Each positioning member 70 can be attached to the interior 11 of the container 10 so as to extend in the vertical direction along the corresponding wall 12. In this embodiment, a part or all of each positioning member 70 is disposed within the recess 12B. A configuration in which a larger portion of the positioning member 70 is disposed within the recess 12B contributes to the effect of improving workability within the interior 11 of the container 10, the capacity to accommodate cargo 100, and the like. "A larger portion" means 70% or more of the volume occupied by the positioning member 70, more preferably 80%, and even more preferably 90% or more.

[0027] In this embodiment, the positioning member 70 has a long portion 71 made of metal, plastic, or the like, and a magnet 72 attached to the long portion 71. The configuration in which the positioning member 70 is attached to the recess 12B by the magnet 72 contributes to improving workability. In this embodiment, the positioning member 70 has a grip portion 73 fixed to the middle portion of the long portion 71 in the extension direction. This configuration also contributes to improving workability.

[0028] A method for restricting movement of the luggage 100 using the luggage holding device 1 of this embodiment will be described. First, as shown in Figure 2, the user attaches a pair of positioning members 70 to the interior 11 of the container 10, and then positions one end and the other end of the beam member 20 at positions corresponding to the positioning members 70. At this time, the user can position the beam member 20 so that one end is supported by the upper end of one positioning member 70 and the other end is supported by the upper end of the other positioning member 70. This leads to the effect that the user can easily and reliably adjust the height positions of both ends of the beam member 20.

[0029] The positioning member 70 may have a structure that allows the height position of its upper end to be adjusted. An example of such a structure may be a double-tube structure that forms the long portion 71, with a hole and a plunger for adjusting the relative positions of the two tubes. The structure may also be any other known structure.

[0030] After the beam member 20 has been placed as described above, the user rotates the rotating member 28B to move the pressing portions 25 in a direction away from the beam main body 24, and presses one pressing portion 25 and the other pressing portion 25 against the pair of walls 12, respectively. This attaches the beam member 20 to the interior 11 of the container 10.

[0031] In this embodiment, the pressing portion 25 has a pressing surface 26 shaped to conform to the recess 12B. This configuration has the effect of firmly attaching both ends of the beam member 20 to the pair of walls 12. Furthermore, the pressing surface 26 shaped to conform to the recess 12B has the effect of preventing an unintended decrease in the pressing force with which the pressing portion 25 presses against the wall 12. The dimension of the pressing portion 25 in the longitudinal direction may be smaller than the dimension of the bottom 12C of the recess 12B by, for example, 3 cm or more, and the pressing portion 25 may be rectangular in plan view, as indicated by the two-dot chain line 29 in FIG. 9 . In this case, when a large force is applied to the beam body 24 in the longitudinal direction, the position of one of the pair of pressing portions 25 may be shifted by, for example, 3 cm in the longitudinal direction. This shift leads to a decrease in the pressing force.

[0032] If the difference between the longitudinal dimension of the top surface 26A and the longitudinal dimension of the bottom portion 12C is 2 cm or less, the decrease in the pressing force is suppressed. Preferably, the difference is 1.5 cm or less, and more preferably, 1 cm or less. Note that, depending on the conditions, etc., there may be no problem even if the difference is 3 cm or more, and this embodiment does not exclude such cases.

[0033] In this embodiment, the pressing portion 25 is provided with a slope 26B, which is aligned with the slope 12D of the recess 12B. In this embodiment, the angle formed between the extension direction of the slope 26B and the extension direction of the recess 12B in a plan view is 10° or less, more preferably 8° or less, and even more preferably 6° or less. The pressing surface 26 is pressed against the recess 12B via the buffer member 27. The slope 26B contributes to preventing a decrease in the pressing force as described above, and this effect is useful. Note that, depending on the conditions, there may be cases where the angle exceeds 10° without causing any problems, and this embodiment does not exclude such cases.

[0034] In one example, the container 10 is transported with the pair of positioning members 70 used to adjust the height positions of both ends of the beam member 20 as described above attached in that position. In this case, the pair of positioning members 70 have the effect of preventing the beam member 20 from moving due to a downward force. In another example, the pair of positioning members 70 used to adjust the height positions of both ends of the beam member 20 as described above are removed from that position and placed in a position for the next adjustment of the height positions of both ends of the beam member 20. This leads to the effect of reducing the number of positioning members 70.

[0035] 1, 2, etc., another pair of positioning members 70 are attached at a position spaced apart in the longitudinal direction from the first pair of positioning members 70 in order to adjust the height positions of both ends of the next beam member 20. Here, each positioning member 70 is provided with a support portion 74 that supports a part of the fastening member 60. The support portion 74 includes a plate, a magnet, etc.

[0036] In this embodiment, the plate is a metal plate such as a partially or fully bent metal sheet, a plastic plate, or the like. As shown in FIG. 2 , one end of the support portion 74 in this embodiment is fixed to the surface of the positioning member 70 by a fastening means such as a bolt, rivet, or welding, and the other end is not fixed to the surface. Furthermore, the support portion 74 in this embodiment extends vertically from one end to the other end and follows the surface. Furthermore, the other end of the support portion 74 in this embodiment has a bent portion bent in a direction away from the surface. This bent portion may be provided in another part of the support portion 74. Furthermore, one end of the support portion 74 may be slightly bent so that the support portion 74 gradually moves away from the surface.

[0037] 2 and other figures, the fastening member 60 has a first flexible member 63 and a second flexible member 64, with a first end 61 provided at one end of the first flexible member 63 and a second end 62 provided at one end of the second flexible member 64. The first end 61 and the second end 62 are metal hooks or the like, and are attached to the corresponding attachment portions 23, respectively.

[0038] The other end of the first flexible member 63 and the other end of the second flexible member 64 are connected to each other by a first connecting member 63A and a second connecting member 64A. Known fastening connecting components for connecting belt-shaped members to each other can be used as the first connecting member 63A and the second connecting member 64A. A tension adjustment mechanism 65 such as a ratchet buckle is provided midway on the first flexible member 63 or the second flexible member 64.

[0039] After attaching both ends of the beam member 20 to the pair of walls 12, the user places the luggage 100 near the beam member 20. In this embodiment, the luggage 100 is a plurality of carts arranged in two rows in the longitudinal direction. Such carts are sometimes called basket carts. By folding some or all of the carts, they are arranged compactly in the longitudinal direction as shown in FIG. 1. In this embodiment, the cart arranged closest to the beam member 20 is arranged so as to contact the beam main body 24 in the longitudinal direction. This restricts movement of the luggage 100 toward the beam member 20.

[0040] As described above, when placing the cargo 100 near the beam member 20, the first connecting member 63A and the second connecting member 64A attached to the beam member 20 can become an obstacle to the work. If necessary, the user can attach the other ends of the flexible members 63 and 64 to the support portions 74 of the pair of positioning members 70, respectively, as shown in FIG.

[0041] When the support portion 74 is a plate, the user sandwiches the flexible members 63, 64 between the surface of the long portion 71 constituting the positioning member 70 and the support portion 74. In this case, it is preferable that the surface faces inward in the width direction of the container 10. When the support portion 74 is a magnet, the user attaches metal parts such as the connecting members 63A, 64A to the magnet. This holds the other ends of the flexible members 63, 64 in a position close to the wall 12. This configuration has the effect of improving the user's ability to secure the luggage 100.

[0042] Next, the user connects the connecting members 63A and 64A together and applies tension to the lashing members 60 using the tension adjustment mechanism 65. When lashing down 10 carts as described below, the tension is preferably 2000 to 2700 N or more. The tension can vary depending on factors such as the weight of the cargo 100 to be lashed down. However, since containers 10 are often loaded with a considerable amount of cargo in order to improve transport efficiency, the tension is preferably 1000 N or more, or 1500 N or more, taking into account the weight of the cargo 100. This restricts movement of the cargo 100, which is surrounded by the beam members 20 and the lashing members 60, away from the beam members 20. In this embodiment, the beam members 20 and the lashing members 60 also restrict movement of the cargo 100 in the width direction.

[0043] In Figure 4, ten trolleys (first load group) are surrounded by one beam member 20 and its securing member 60. The mass of one trolley is approximately 100 kg. The maximum deceleration (negative acceleration) when a truck brakes is thought to be 0.4 G, 0.5 G, etc. For example, if an excessive force of 1 G is applied to the ten trolleys when braking, the beam member 20 will be subjected to a force of 10 kN. At this time, the beam body 24, movable member 40, etc. of the beam member 20 will bend within the elastic deformation range, and the holding mechanism 50 of the movable member 40 will also bend within the elastic deformation range, shortening the beam member 20 by the amount of bending. Depending on how the force is applied, some plastic deformation may occur in the beam body 24, movable member 40, etc.

[0044] Even in this case, the configuration in which the slopes 26B are aligned along the slopes 12D of the recesses 12B is useful for maintaining the pair of pressing portions 25 in the corresponding recesses 12B. This configuration leads to effects such as safe transportation of the cargo 100, prevention of damage to the cargo 100, and prevention of damage to the interior 11 of the container 10 caused by the cargo 100 that has come undone.

[0045] In addition, the inclined surface 26B contacts the inclined surface portion 12D via the buffer member 27. This configuration is useful for maintaining the pair of pressing portions 25 in the corresponding recesses 12B. The buffer member 27 is also useful for preventing damage to the interior 11 of the container 10. Taking the above-mentioned circumstances into consideration, the movable member 40 is, for example, a metal cylindrical member having a diameter of 15 mm or more, and more preferably, the diameter of the cylindrical member is 20 mm or more.

[0046] As described above, the user adjusts the positions of the pair of attached positioning members 70 as needed so that the first connecting member 63A and the second connecting member 64A do not interfere with the work. Then, after attaching both ends of the beam member 20 to the pair of walls 12 using the pair of positioning members 70 as described above, the user secures the second group of luggage in the same manner as securing the first group of luggage. Specifically, the second group of luggage also consists of multiple carts or the like, and the user places luggage 100 near the attached beam members 20 and secures the second group of luggage using the lashing members 60 in the same manner as securing the first group of luggage. The next group of luggage, the third group of luggage, can also be secured in the same manner.

[0047] In this way, the beam members 20 of the cargo retaining device 1 of this embodiment can be attached at any position in the longitudinal direction of the container 10, and the user can align and attach multiple beam members 20 at any interval in the longitudinal direction. This configuration can achieve the effect of improving the degree of freedom in the securing manner according to the shape, quantity, weight, etc. of the cargo 100, and can achieve the effect of stably securing the cargo 100 without modification as described above in situations where it is not possible to continue using the same container 10. The cargo 100 may be a pallet on which various parts, products, and other articles are placed, or a box containing various parts, products, and other articles.

[0048] Furthermore, the wall 12 of the container 10 may have deformed portions that protrude toward the interior 11, for example, due to contact with other containers 10. The user can install the beam members 20 while avoiding recesses 12B or height positions where such deformed portions exist, which leads to the effect of securely securing the cargo.

[0049] In this embodiment, the beam member 20 is disposed on the side of the wall 13 at one end in the longitudinal direction of the container 10, and the lashing members 60 are disposed on the side of the wall at the other end in the longitudinal direction of the container 10 relative to the beam member 20. Since a door or the like is provided on the wall at the other end, this configuration can be said to have the effect of facilitating the above-mentioned lashing and lashing release operations by the user.

[0050] Unlike this embodiment, a structure in which the attached portion 23 is directly attached to the beam member 20 is also conceivable. For example, the attached portion 23, such as a metal ring, is attached to the surface of the beam body 24 facing the longitudinal direction so as to be swingable, for example, in the width direction or up and down direction. If the attached portion 23 is not swingable, it may get in the way when storing the beam member 20, or the attached portion 23 may damage the cargo 100, etc.

[0051] When the fastening member 23 is directly attached to the beam member 20 in this manner, it is not uncommon for the fastening member 23 to become pinched between the cargo 100 and the metal portion of the beam member 20. In this state, even if the user attaches the first end 61 or the like of the lashing member 60 to the fastening member 23 and applies tension to the lashing member 60 using the tension adjustment mechanism 65, the pinched state of the fastening member 23 may not be released. In this case, if the pinched state is released due to vibrations or the like caused by the container 10 being moved, the tension of the lashing member 60 will decrease.

[0052] In this embodiment, the attached portion 23 is attached to the beam member 20 via a flexible connecting member 23A. This configuration has the effect of preventing any of the above undesirable situations.

[0053] In the state shown in Fig. 2, the positioning member 70 may be attached to one end of the beam member 20. Alternatively, the positioning member 70 may be attached to one end of the beam member 20 by a hinge (not shown), and the positioning member 70 may be able to swing in the extending direction of the beam member 20 as shown by the dashed-dotted arrow in Fig. 2. This configuration leads to the effects of facilitating the storage of the beam member 20 and the positioning member 70 when not in use, and facilitating the installation of the beam member 20 to the container 10 using the positioning member 70.

[0054] In the first modified example, it is also possible to use a pressing portion 25' that has a different shape from the pressing portion 25, as shown in Figure 10. The other structures are the same as those of the above embodiment. The pressing surface 26 of the pressing portion 25' has a bottom surface 26C instead of the top surface 26A of the pressing portion 25, and the slopes 26B-bottom surface 26C-slope 26B are arranged in this order in the longitudinal direction. In this case, the bottom surface 26C of the pressing portion 25' faces the top of the convex portion 12A, and the slope 26B faces the slope portion 12D, as in the above embodiment. Even in this case, because the slope 26B faces the slope portion 12D, the same effect as in the above embodiment can be achieved.

[0055] In the second modified example, it is also possible to use a pressing portion 25'' that has a different shape from the pressing portion 25, as shown in FIG. 11. The other structures are the same as those of the above embodiment. The pressing surface 26 of the pressing portion 25" differs from the pressing portion 25 in the arrangement of the top surface 26A, the inclined surface 26B, and the bottom surface 26C. On the pressing surface 26 of the pressing portion 25", the arrangement is in the order of inclined surface 26B-top surface 26A-inclined surface 26B-bottom surface 26C-inclined surface 26B-top surface 26A-inclined surface 26B. Even in this case, since the inclined surface 26B faces the inclined surface portion 12D, the same effect as in the above embodiment can be achieved. Other types of pressing portions can also achieve the effects of the above embodiments.
