The connecting portion 32 is extended toward the first contact surface 40 in the separation direction D3. As a result, the inner width dimension W1 of the insertion recess 71 is expanded to the width dimension W2 of the work 90, and the insertion recess 71 can be inserted into the corner of the work 90. FIG. After that, the worker releases the sandwiching of the protective material 70, so that the inner width W1 of the insertion recess 71 is narrowed, and the first and second contact surfaces 40, 50 contact the opposing surfaces of the workpiece 90. As shown in FIG.

The operator similarly inserts the remaining protective materials 70 into the corners of the workpiece 90 . As a result, as shown in FIG. 1 , the first side portions 12 of the protective member 70 are fitted to the four corners of the work 90 while protruding outward in the width direction of the work 90 .

, the second members 10 and 20 may be subjected to similar loads. On the other hand, the connecting member 30 connecting the first and second members 10 and 20 is composed of first to third connecting portions 31 to 33. Even if a load is applied from any direction, the deformation of the first to third connecting portions 31 and 33 respectively absorbs the positional deviation between the first and second members 10 and 20, and each connecting portion 311 of the protective material 70 , 321 can be made less likely to be damaged.

In the embodiment described above, the following effects can be obtained.
The connecting member 30 that connects the first and second members 10 and 20 has the first to third connecting portions 31 to 31 when a load is applied to the first and second members 10 and 20 from any direction. The deformation of each of the members 33 can absorb the positional deviation between the first member 10 and the second member 20 due to the load. As a result, it is possible to make the protective member 70 less likely to be damaged at the connecting portions 311 and 321 .

The first and second connecting portions 31 and 32 have a pair of bent portions 312 and 322, respectively. As a result, when the workpiece 90 having the width dimension W2 larger than the inner width dimension W1 is inserted into the insertion recess 71 of the protection member 70, the pair of bent portions 312 and 322 are stretched in the separating direction D3. The inner width dimension W1 of the insertion recess 71 in the separating direction D3 can be increased. This makes it easier to insert the workpiece 90 into the insertion recess 71 .

When the insertion recess 71 of the protective member 70 is inserted into a part of the work 90 and the first connecting portion 31 and the second connecting portion 32 are deformed so as to be elongated in the separation direction D3, the first and second extensions are formed. The provision portions 313 and 323 can increase the amount by which the first and second connecting portions 31 and 32 are stretched. As a result, the inner width dimension W1 of the insertion recess 71 in the separation direction D3 can be further increased, and the workpiece 90 can be easily inserted into the insertion recess 71 .

Since the protective member 70 can increase the amount of deformation on the side of the first and second members 10 and 20 where the separation distance L is large, the inner width dimension W1 of the insertion recess 71 can be further widened. This makes it easier to insert an article into the insertion recess 71 .

By deforming the protective member 70 so as to narrow the separation distances LA1 and LB1 on the side of the corner 46 with respect to the first and second connecting members 30A and 30B, the inner width dimension W1 of the insertion recess 71 is: The dimensions on the side of the outer peripheral edge portions 43 and 53 can be widened. This makes it easier to insert the insertion recesses 71 into the four corners of the work 90 .

Since the first and second members 10 and 20 are connected by the first to fourth connecting members 30A to 30D, the amount of deformation of the protective material 70 is not greatly hindered, and the protective material 70 is less likely to be damaged. be able to.

In the protective member 70, when the distance in the separation direction D3 between the contact surfaces 40 and 50 is greatly deformed, the first opposing portion 315 of the first connecting portion 31 contacts the first and second connecting side surfaces 44 and 45. , the second opposing portion 325 of the second connecting portion 32 abuts against the third and fourth connecting side surfaces 54, 55, so that excessive deformation of the first and second connecting portions 31, 32 can be restricted. As a result, the protection member 70 can be made more difficult to break.

(Modified example of the first embodiment)
5A and 5B are diagrams illustrating different usage examples of the protective material 70. FIG. In FIG. 5, a workpiece 91 indicated by a dashed line is smaller in size than the workpiece 90 shown in the above-described embodiment. In this embodiment, the workpiece 91 can be protected by inserting almost the entire workpiece 91 into the insertion recess 71 of the protective material 70 . Moreover, the protection member 70 with the work 91 inserted therein can be housed in the outer container 80 to store or transport the work 91 . The outer container 80 is a rectangular parallelepiped member with an open upper surface, and has a housing recess 81 that matches the shape of the protective member 70 . When using the protective material 70 , after inserting the work 91 into the insertion recess 71 of the protective material 70 , the protective material 70 is housed in the housing recess 81 of the outer container 80 together with the work 91 . Alternatively, after housing the protective material 70 in the housing recess 81 of the outer container 80 , the workpiece 91 is inserted into the insertion recess 71 . As a result, the deformation of the connecting member 30 absorbs and disperses variations in dimensional accuracy and deformation of the outer container 80 or the workpiece 91 , thereby stabilizing the housing state of the protective member 70 in the outer container 80 . Further, for example, by stacking another outer container 80 above another outer container 80, a plurality of works 91 can be aligned and stored or transported.

(Second embodiment)
In the second embodiment, a configuration different from that of the first embodiment will be mainly described. Parts in the second embodiment that are the same as those in the first embodiment are denoted by the same reference numerals, and description thereof will not be repeated.

The first and second connecting portions 31 and 32 of the connecting member 30 are not limited to the shapes shown in FIGS. In the first connecting member 30A shown in FIG. 6, the shape of the first and second connecting portions 31 and 32 on the corner portion 46 side differs from that shown in the first embodiment. Specifically, the first and second connecting portions 31 and 32 on the corner portion 46 side are bent. That is, the bent portion may have a bent shape. The second connecting member 30B may also have the same shape as the first connecting member 30A shown in FIG.

As shown in FIG. 7, in the first and third connecting members 30A and 30C, the first and second extended portions 313 and 323 do not extend linearly between the pair of bent portions 312 and 322. , may be curved. In addition, in the first connecting member 30A, even if the bent shape of the pair of bent portions 312 and 322 on the side of the corner portion 46 in the first direction D1 is gentler than in the above-described embodiment (sharp shape). good. Specifically, the bent portions 312 and 322 may have obtuse angles. That is, the angle of the bent portion of the connecting member 30 may be an acute angle, an obtuse angle, or a right angle. The second connecting member 30B may also have the same shape as the first connecting member 30A shown in FIG. The fourth connecting member 30D may also have the same shape as the third connecting member 30C shown in FIG.

As shown in FIG. 8, in the first and third connecting members 30A, 30C, the bending amount of the pair of bending portions 312, 322 may be steeper than in the above-described embodiment. Specifically, the pair of first bent portions 312 has a large amount of bending toward the first connecting portion 311 side, and the pair of second bending portions 322 has a large amount of bending toward the second connecting portion 321 side. . The second connecting member 30B may also have the same shape as the first connecting member 30A shown in FIG. The fourth connecting member 30D may also have the same shape as the third connecting member 30C shown in FIG.

As shown in FIG. 9, the first and third connecting members 30A and 30C may be curved in a concave shape at the first facing portion 315 and the second facing portion 325 . The second connecting member 30B may also have the same shape as the first connecting member 30A shown in FIG. The fourth connecting member 30D may also have the same shape as the third connecting member 30C shown in FIG.

In the first embodiment, each connecting side surface 44, 45, 54, 55 forms a plane. Alternatively, as shown in FIG. 10, the first connecting side surface 44 and the third connecting side surface 54 may be partially recessed so that they do not form a flat surface. Specifically, a first recessed portion 47 is formed in the first connecting side surface 44 between two connecting portions of the first connecting member 30A (the portion facing the first opposing portion 315). A second indented portion 57 is formed between two connecting portions 321 of the third connecting side surface 54 . As a result, when the protective member 70 is deformed so as to change the separation distance L between the first member 10 and the second member 20 , the first facing portion 315 is moved by the first indented portion 47 to the first connecting side surface 44 . , and the second indented portion 57 makes it difficult for the second opposing portion 325 to contact the third connecting side surface 54 . As a result, the amount of deformation of the first connecting member 30A can be increased, and the inner width W1 of the insertion recess 71 can be easily widened. Moreover, in the usage example of the protective material 70 shown in FIG. 5, the protective material 70 can be easily accommodated in the outer container 80 .
