Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the above conventional electrical equipment built-in panel, the number and size of the devices arranged inside vary depending on the installation location, and when the variations in the device configuration increase, the types of cases also increase, which may cause difficulties in storage.

[0005] Therefore, in view of such circumstances, an object of the present invention is to provide an electrical equipment built-in panel that is easy to store.

Means for Solving the Problems

[0006] The electrical equipment built-in panel of the present invention includes electrical equipment arranged in an electric circuit for electrically connecting a power source and a load, a base plate formed in a plate shape having a front surface extending in a first direction and a second direction orthogonal to each other, and the electrical equipment is attached to the front surface, a holding member that can be fixed to an installation location and can hold the base plate, A pair of the retaining members are provided in a disconnected and separated state in one of the first and second directions.

[0007] With the above configuration of the electrical equipment built-in panel, by adjusting the spacing between a pair of retaining members in one direction according to the size of the base plate in one direction, the retention of the base plate by the pair of retaining members can be made to correspond to the size of the base plate. Therefore, the number of types of retaining members can be reduced, making storage easier.

[0008] In the electrical equipment built-in panel of the present invention, The device comprises a base plate held by a pair of the aforementioned holding members, and a cover that covers the electrical equipment from the front side, The cover may be configured to be held in place by being connected to a pair of the retaining members.

[0009] In this way, the cover can be held in place by a pair of retaining members, thereby covering the base plate and electrical equipment from the front.

[0010] In the electrical equipment built-in panel of the present invention, The cover may be configured to allow the length in one of the directions to be changed.

[0011] If you do this, Since the length of one side of the cover can be changed to match the distance between the pair of retaining members in one direction, the number of cover types can be reduced, making storage easier.

[0012] The electrical equipment built-in panel of the present invention is The pair of holding members may be identical in shape and may face each other in the same orientation in one direction, or they may face each other in different orientations.

[0013] This approach, where each pair of retaining members has the same shape, reduces the number of different types of retaining members, making storage easier.

[0014] In the panel with built-in electrical equipment of the present invention, the holding member is a plate-like body that extends in the first direction and the second direction, and can be fixed to the installation location by facing the third direction orthogonal to the first direction and the second direction towards the installation location, a concave portion may be formed on the surface of the holding member that is far from the installation location in the third direction and opens, and the surface closer to the installation location serves as the inner surface, and a screw-through hole for screwing that penetrates in the third direction is formed on the inner surface of the concave portion.

[0015] In this way, a concave portion is formed in the holding member, and when the holding member is screwed and fixed to the installation location by inserting a screw through the through hole on the inner surface from the opening side of the concave portion, chips (such as wood chips and metal chips) generated can be received by the concave portion. Therefore, it is possible to prevent the chips from adhering to the base plate or the electrical equipment.

Advantages of the Invention

[0016] As described above, the panel with built-in electrical equipment of the present invention can achieve an excellent effect of being easy to store.

[Modes for carrying out the invention]

[0018] The following describes an electrical equipment control panel according to one embodiment of the present invention, with reference to the attached drawings.

[0019] The electrical equipment control panel 1 has a box-like appearance, as shown in Figures 1, 2, and 3.

[0020] As shown in Figure 4, the electrical equipment enclosure 1 of this embodiment comprises an electrical device 2 arranged in an electrical circuit that electrically connects a power source and a load, a base plate 3 for mounting the electrical device 2, a pair of holding members 4 that can be fixed to the installation location and can hold the base plate 3, and a cover 5 (see Figures 1, 2, and 3) that covers the base plate 3 and the electrical device 2 held by the pair of holding members 4 from the front.

[0021] When viewing the electrical equipment enclosure 1 from the front, the direction in which the pair of holding members 4 described later are aligned is referred to as the first direction, the direction perpendicular to the first direction when viewing the electrical equipment enclosure 1 from the front is referred to as the second direction, and the direction perpendicular to both the first and second directions is referred to as the third direction.

[0022] The electrical equipment panel 1 contains multiple electrical devices 2. These electrical devices 2 include, for example, changeover switches, circuit breakers, and earth leakage circuit breakers, and constitute a circuit that electrically connects the power source and the load.

[0023] As shown in Figures 5 and 6, the base plate 3 has a plate-shaped base portion 30 having a front surface that extends in a first and second direction perpendicular to each other, a plurality of mounting portions 31 extending outward from both ends in the first direction, and an auxiliary base portion 32 (see Figure 5) that is superimposed and fixed on the base portion 30.

[0024] The base plate 3 is configured so that electrical equipment 2 can be mounted on its front. More specifically, the base plate 3 in this embodiment is configured so that electrical equipment 2 can be mounted on its front via an auxiliary base portion 32.

[0025] In the base plate 3, two mounting portions 31 extend from one end of the base portion 30 in the first direction, and two mounting portions 31 also extend from the other end of the base portion 30 in the first direction.

[0026] In the following description, the two mounting portions 31 extending from one end of the base portion 30 in the first direction, the two mounting portions 31 extending from the left end of the base portion 30 in Figure 6, will be referred to as the one-end mounting portion 31, and the two mounting portions 31 extending from the other end of the base portion 30 in the first direction, the two mounting portions 31 extending from the right end of the base portion 30 in Figure 6, will be referred to as the other-end mounting portion 31.

[0027] The two one-end mounting portions 31 are arranged with a gap between them in the second direction. Similarly, the two other-end mounting portions 31 are also arranged with a gap between them in the second direction.

[0028] Furthermore, one of the two one-end mounting portions 31 corresponds to one of the two other-end mounting portions 31 in terms of their formation position in the second direction, and the other of the two one-end mounting portions 31 also corresponds to the other of the two other-end mounting portions 31 in terms of their formation position in the second direction.

[0029] The auxiliary base section 32 is used in a way that matches the number of electrical devices 2 and their shapes (see Figure 5).

[0030] The pair of retaining members 4 are plate-shaped and have the same shape as each other (see Figures 7 and 8).

[0031] As shown in Figure 9, the holding member 4 includes a base body portion 40 extending along the second direction, a fixed portion 41 formed at the end of the base body portion 40 in the second direction and constituting a fixed portion to the installation location, a debris-stopping wall portion 42 formed on the fixed portion 41, a detachable portion 43 formed on the base body portion 40 and capable of detaching the mounting portion 31 of the base plate 3, and a base-side connecting portion 44 provided on the base body portion 40 and constituting a connecting portion with the cover 5.

[0032] As shown in Figures 10(a) and 10(b), the base body portion 40 has a pair of front and rear surfaces 400a and 400b arranged in a third direction, and an inward-facing surface 400c arranged in a first direction.

[0033] The fixed portion 41 includes a pair of first fixing portions 410a and 410b provided at one end of the base body portion 40 in the second direction, and a pair of second fixing portions 411a and 411b provided at the other end of the base body portion 40 in the second direction.

[0034] In this embodiment, the fixed portion 41 is configured such that a pair of first fixed portions 410a and 410b are positioned above, and a pair of second fixed portions 411a and 411b are positioned below.

[0035] One of the pair of first fixing parts 410a and 410b, the first fixing part 410a, has a recess formed therein that opens to one side in the third direction and also opens outward in the second direction, as shown in Figure 11. Therefore, this recess is formed to open on one of the front and rear surfaces 400a of the base body part 40.

[0036] Furthermore, one of the first fixing parts 410a has a rear surface 410aa that faces the same direction as one of the front and rear surfaces 400a, and a lower surface 410ab that rises from the rear surface 410aa in a third direction and faces outward in a second direction, A recess is formed by a pair of side surfaces 410ac that rise from the back surface 410aa in a third direction and face each other in a second direction.

[0037] A through-hole 410ad is formed in the back surface 410aa, which penetrates in a third direction. A fastener (e.g., a screw) is inserted into this through-hole 410ad to secure the installation location.

[0038] As shown in Figure 12, the other first fixing part 410b of the pair of first fixing parts 410a and 410b has a recess formed therein that opens to the other side in the third direction and also opens outward in the second direction. Therefore, this recess is formed to open on the other front and rear surface 400b of the base body part 40.

[0039] Furthermore, in the other first fixing portion 410b, a recess is formed by a rear surface 410ba that faces the same direction as the front and rear surfaces 400b of the other, a lower surface 410bb that rises from the rear surface 410ba in a third direction and faces outward in a second direction, and a pair of side surfaces 410bc that rise from the rear surface 410aa in a third direction and face each other in a second direction.

[0040] A through-hole 410bd is formed in the back surface 410ba, extending through in a third direction. This through-hole 410bd is a hole into which a fastener (e.g., a screw) for securing the installation location is inserted.

[0041] In the holding member 4, when the other front and rear surface 400b is facing the installation location, one front and rear surface 400a becomes the surface farther from the installation location in the third direction, and the other front and rear surface 400b becomes the surface closer to the installation location in the third direction. At this time, the recess of one of the first fixing parts 410a becomes open on the far side and closed on the close side (see Figure 11).

[0042] Furthermore, when the holding member 4 is positioned with the other front and rear surface 400b facing the installation location, the rear surface 410aa of one of the first fixing parts 410a is screwed to the installation location. At this time, any debris (wood chips, metal chips, etc.) generated can be received by the lower surface 410ab of the recess.

[0043] Furthermore, in the holding member 4 of this embodiment, a debris-stopping wall portion 42 is formed so as to protrude outward in the second direction from the lower surface 410ab of one of the first fixing portions 410a, thereby preventing debris received on the lower surface 410ab from scattering.

[0044] The tip of the debris-blocking wall portion 42 is formed in a concave shape to match the position of the through hole 410ad, so that the front of the through hole 410ad is open. This makes it easier to insert and remove screws into the through hole 410ad, or to turn screws that have passed through the through hole 410ad with a tool.

[0045] Then, in the holding member 4, when one front / rear surface 400a is facing the installation location, the other front / rear surface 400b becomes the surface farther from the installation location in the third direction, and the one front / rear surface 400a becomes the surface closer to the installation location in the third direction. At this time, the recess of the other first fixing part 410a becomes open on the far side and closed on the close side (see Figure 12).

[0046] Furthermore, when the retaining member 4 is positioned with one front / rear surface 400a facing the installation location, the rear surface 410ba of the other first fixing part 410b is screwed to the installation location. Any debris (wood chips, metal chips, etc.) generated at this time is collected on the lower surface 410bb of the recess.

[0047] The tip of this debris-blocking wall portion 42 is also formed in a concave shape to match the position of the through hole 410bd, so that the front of the through hole 410bd is open. This makes it easier to insert and remove screws into the through hole 410bd, or to turn screws that have passed through the through hole 410bd with a tool.

[0048] One of the pair of second fixing parts 411a, 411b, the second fixing part 411a, has a counterbore 411aa that opens to one side in the third direction, and a through hole 411ab that penetrates the counterbore 411aa in the third direction, as shown in Figure 10(a). Therefore, this counterbore 411aa is formed to open on one of the front and rear surfaces 400a of the base body part 40.

[0049] The through hole 411ab formed in the second fixing portion 411a is also a hole into which a fixing device (for example, a screw) to the installation location is inserted.

[0050] As shown in Figure 10(b), the other second fixing part 411b of the pair of second fixing parts 411a and 411b has a counterbore 411ba that opens to the other side in the third direction, and a through hole 411bb that penetrates the counterbore 411ba in the third direction. Therefore, this counterbore 411ba is formed to open on the other front and rear surface 400b of the base body part 40.

[0051] When the holding member 4 is positioned with the other front and rear surface 400b facing the installation location, the counterbore portion 411aa of one of the second fixing portions 411a becomes open on the far side (see Figure 10(a)), and when the holding member 4 is positioned with one of the front and rear surfaces 400a facing the installation location, the counterbore portion 411ba of the other second fixing portion 411b becomes open on the far side (see Figure 10(b)).

[0052] Two attachment / detachment parts 43 are formed on the base body part 40. The two attachment / detachment parts 43 are positioned apart from each other in the second direction.

[0053] As shown in Figure 11, the attachment / detachment portion 43 is formed with an attachment / detachment recess 430 that opens on one front / rear surface 400a and an inward surface 400c, and a fixing groove portion 431 that is continuous with the attachment / detachment recess 430 and allows the attachment portion 31 to be inserted and removed in a second direction.

[0054] The inner surface 4300 of the detachable recess 430 is formed in a stepped shape, and the depth in the third direction is greater on one side in the second direction than on the other end in the second direction.

[0055] The fixing groove 431 is continuous with the attachment / detachment recess 430 and extends straight in the second direction. The fixing groove 431 is also formed to open on the inward-facing surface 400c. Furthermore, since the fixing groove 431 is formed in the center of the retaining member 4 in the third direction, the position in the third direction does not change whether one front / rear surface 400a or the other front / rear surface 400b is facing the installation location.

[0056] As shown in Figure 10, the base-side connecting portion 44 has a plurality of base-side protrusions 440 that extend outward in the second direction from one end of the base body portion 40 in the second direction.

[0057] Furthermore, the multiple base-side protrusions 440 are arranged with gaps between them in the first direction. Therefore, the base-side connecting portion 44 is formed in a comb-like shape.

[0058] As shown in Figure 13, the cover 5 includes a cover body portion 50 that is placed on top of the pair of retaining members 4, a cover-side connecting portion 51 formed on the cover body portion 50 and connectable to the base-side connecting portion 44, and a restricting structure 52 for restricting the movement of the base plate 3 relative to the retaining members 4.

[0059] More specifically, the cover body 50 has a pair of cover ends 500 that are arranged to overlap the holding member 4 from the front side in the third direction, and a cover variable part 501 that connects the cover ends 500 and can change the distance between the pair of cover ends 500 in the first direction (see Figure 2).

[0060] One end of the cover 500 is positioned overlapping one of the retaining members 4, and the other end of the cover 500 is positioned overlapping the other retaining member 4.

[0061] The cover variable portion 501 is configured to allow its length to be changed in the first direction. Therefore, shortening the size of the cover variable portion 501 in the first direction reduces the distance between the pair of cover ends 500 in the first direction, and lengthening the size of the cover variable portion 501 in the first direction increases the distance between the pair of cover ends 500 in the first direction.

[0062] The cover variable section 501 of this embodiment has a plurality of variable connecting members 5010 that can be connected between a pair of cover ends 500 in an aligned state in a first direction.

[0063] Both ends of the variable connecting member 5010 in the first direction (the direction in which they are aligned) are configured to be connectable to the inner end of the cover end 500 (the end that is positioned inward in the first direction) or to the end of another variable connecting member 5010.

[0064] In this embodiment, the variable connecting member 5010 has interlocking parts 5011 with a concave and concave shape formed at one end and the other end. As a result, the cover 5 can connect multiple variable connecting members 5010 in an aligned state in the first direction by combining the interlocking part 5011 at one end of one variable connecting member 5010 with the interlocking part 5011 at the other end of another variable connecting member 5010 in the first direction.

[0065] Furthermore, one end of the variable connecting member 5010 is configured to be combined in a first direction with a recessed fitting portion 5000 formed on the inner end of one cover end 500, and the other end of the variable connecting member 5010 is configured to be combined in a first direction with a recessed fitting portion 5000 formed on the inner end of the other cover end 500.

[0066] The variable connecting member 5010 of this embodiment includes three types of variable connecting members 5010: an upper variable connecting member 5010 positioned at one end in the second direction, a lower variable connecting member 5010 positioned at the other end in the second direction, and a middle variable connecting member 5010 positioned between the upper variable connecting member 5010 and the lower variable connecting member 5010.

[0067] The cover-side connecting portion 51 is formed on one cover end 500 and the other cover end 500.

[0068] The cover-side connecting portion 51 of this embodiment has a plurality of cover-side protrusions 510 that extend inward in a third direction from one end of the cover end portion 500 in a second direction.

[0069] Furthermore, the multiple cover-side protrusions 510 are arranged with gaps between them in the first direction. Therefore, the cover-side connecting portion 51 is formed in a comb-like shape.

[0070] When one retaining member 4 and one cover end 500 are overlapped in the third direction, the base-side connecting portion 44 of one retaining member 4 and the cover-side connecting portion 51 of one cover end 500 are joined together. When the other retaining member 4 and the other cover end 500 are overlapped in the third direction, the base-side connecting portion 44 of the other retaining member 4 and the cover-side connecting portion 51 of the other cover end 500 are joined together. As a result, the pair of retaining members 4 and the cover 5 are connected (see Figure 18).

[0071] The restricting structure 52 includes a front restricting portion 520 for restricting the movement of the base plate 3 in a third direction, and a vertical restricting portion 521 for restricting the movement of the base plate 3 in a second direction.

[0072] The front restricting portion 520 is configured to be inserted into the front of the other side in the second direction of the back surface 4300 within the attachment recess 430 when the cover 5 is placed over the pair of retaining members 4. When the mounting portion 31 is inserted into the fixing groove portion 431 and positioned within the attachment recess 430, and the front restricting portion 520 is inserted into the front of the other side in the second direction of the back surface 4300 within the attachment recess 430, the mounting portion 31 is sandwiched in a third direction by the other side of the back surface 4300 and the front restricting portion 520. This restricts the movement of the mounting portion 31 (base plate 3) in the third direction.

[0073] The vertical restricting portion 521 is configured to be inserted into the front of one side in the second direction of the back surface 4300 within the attachment / detachment recess 430 when the cover 5 is placed over the pair of retaining members 4. When the mounting portion 31 is inserted into the fixing groove portion 431 and positioned within the attachment / detachment recess 430, and the vertical restricting portion 521 is inserted into the front of one side in the second direction of the back surface 4300 within the attachment / detachment recess 430, the mounting portion 31 is sandwiched in the second direction between the bottom surface of the fixing groove portion 431 and the vertical restricting portion 521. This restricts the movement of the mounting portion 31 (base plate 3) in the second direction.

[0074] The configuration of the electrical equipment enclosure 1 according to this embodiment is as described above. Next, the operation of the electrical equipment enclosure 1 will be explained.

[0075] To install the electrical equipment enclosure 1 of this embodiment, first, the pair of retaining members 4 are fixed to the installation location.

[0076] The pair of retaining members 4, fixed to the installation site, are arranged in a first direction with a gap between them that matches the size of the base plate 3.

[0077] Furthermore, the other retaining member 4 is in a reversed state, having rotated in the circumferential direction around the axis extending in the second direction relative to the first retaining member 4.

[0078] Furthermore, one of the retaining members 4 is positioned so that its front and rear surfaces 400b are facing the installation site, while the other retaining member 4 is positioned so that its front and rear surfaces 400a are facing the installation site.

[0079] Next, the base plate 3 is attached to the pair of retaining members 4. The process of attaching the base plate 3 to the pair of retaining members 4 involves a temporary fastening process in which the base plate 3 is temporarily secured to the pair of retaining members 4, and a final fixing process in which the base plate 3 is permanently secured to the pair of retaining members 4.

[0080] When the temporary fastening work is performed, the mounting portion 31 (the other end mounting portion 31 in this embodiment) is temporarily fastened to the attachment / detachment portion 43 of the retaining member 4, which is positioned with one front / rear surface 400a facing the installation location, and the remaining mounting portion 31 (the one end mounting portion 31 in this embodiment) is temporarily fastened to the attachment / detachment portion 43 of the retaining member 4, which is positioned with the other front / rear surface 400b facing the installation location.

[0081] In the following description, a retaining member 4 with one front / rear surface 400a facing the installation location will be referred to as the reverse-facing retaining member 4, and a retaining member 4 with the other front / rear surface 400b facing the installation location will be referred to as the front-facing retaining member 4.

[0082] In the temporary fixing work of this embodiment, first, the entire base plate 3 is tilted by bringing the other end mounting portion 31 closer to the installation location than the one end mounting portion 31, and the other end mounting portion 31 is positioned within the attachment / detachment recess 430 of the reverse-facing holding member 4.

[0083] Next, the mounting portion 31 on one end is brought closer to the installation location and placed inside the attachment / detachment recess 430 of the facing retaining member 4.

[0084] Then, when the entire base plate 3 is slid toward the fixing groove portion 431, the mounting portion 31 on the other end is inserted into the fixing groove portion 431 of the facing retaining member 4, and the mounting portion 31 on the one end is inserted into the fixing groove portion 431 of the facing retaining member 4.

[0085] This temporarily fastens the base plate 3 to the pair of retaining members 4.

[0086] During the fixing process, the cover 5 is placed over the base plate 3 and the pair of retaining members 4, while the front restricting portion 520 and the vertical restricting portion 521 are inserted into the attachment / detachment portion 43 of the retaining member 4 with the front facing outwards.

[0087] In this manner, as the front restricting portion 520 is inserted into the front of the other side in the second direction of the back surface 4300 within the attachment recess 430, the one-end mounting portion 31 is sandwiched in a third direction between the other side of the back surface 4300 and the front restricting portion 520. This restricts the movement of the one-end mounting portion 31 (base plate 3) in the third direction.

[0088] Furthermore, as the vertical restricting portion 521 is inserted into the front of one side in the second direction of the back surface 4300 within the attachment recess 430, the other end mounting portion 31 is sandwiched in the second direction between the bottom surface of the fixing groove portion 431 and the vertical restricting portion 521. This restricts the movement of the other end mounting portion 31 (base plate 3) in the second direction.

[0089] This ensures that the base plate 3 is fully attached to the pair of retaining members 4.

[0090] Then, the cover 5 is placed on top of the pair of holding members 4, the electrical equipment 2, and the base plate 3 from the front side, and when the cover-side connecting part 51 and the base-side connecting part 44 are connected to each other, the cover 5 is fixed to the pair of holding members 4.

[0091] The electrical equipment control panel 1 of this embodiment is installed in the installation location in this manner.

[0092] As described above, in the electrical equipment built-in panel 1 according to this embodiment, a pair of retaining members 4 are provided in a disconnected state and separated in one of the first and second directions. By adjusting the separation distance of the pair of retaining members 4 in one direction according to the size of the base plate 3 in one direction, the retention of the base plate 3 by the pair of retaining members 4 can be made to correspond to the size of the base plate 3. Therefore, the number of types of retaining members 4 can be reduced, which has the excellent effect of making storage easier.

[0093] Furthermore, the electrical equipment enclosure 1 includes a base plate 3 held by a pair of retaining members 4, and a cover 5 that covers the electrical equipment 2 from the front. Since the cover 5 is connected to and held by the pair of retaining members 4, the base plate 3 and the electrical equipment 2 can be covered from the front by holding the cover 5 to the pair of retaining members 4.

[0094] Furthermore, since the cover 5 is configured to have a length that can be changed in one direction, the length of the cover 5 in one direction can be changed to match the distance between the pair of retaining members 4 in one direction, thereby reducing the number of different types of covers 5 and improving ease of storage.

[0095] Furthermore, since the pair of retaining members 4 are identical in shape and configured to face each other in different orientations in one direction, the ease of storage is enhanced by making the pair of retaining members 4 identical in shape and reducing the number of different types of retaining members 4.

[0096] Furthermore, the retaining member 4 has a recess formed on the side furthest from the installation location in the third direction, and a recess that is not open to the side close to the installation location. In addition, through holes 410ad and 410bd for screw fastening are formed in the back surfaces 410aa and 410ba of the recess, penetrating in the third direction. As a result, when the retaining member 4 is screwed to the installation location by inserting screws from the opening side of the recess through the through holes 410ad and 410bd in the back surfaces 410aa and 410ba, the debris generated can be received in the recess. Therefore, it is possible to suppress the adhesion of debris to the base plate 3 and the electrical equipment 2.

[0097] Furthermore, since debris-stopping walls 42 are formed on the lower surfaces 410ab and 410bb of the recesses, debris received on the lower surfaces 410ab and 410bb is less likely to scatter.

[0098] It should be noted that the electrical equipment built-in panel according to the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0099] In the above embodiment, the electrical equipment enclosure 1 was configured such that a pair of holding members 4 were arranged side by side horizontally, but the configuration is not limited to this. For example, the electrical equipment enclosure 1 may be configured such that a pair of holding members 4 are arranged side by side vertically.

[0100] In other words, the pair of holding members 4 may be arranged side by side in the direction referred to as the second direction in the description of the electrical equipment built-in panel 1 of the above embodiment.

[0101] In the above embodiment of the electrical equipment enclosure 1, the cover 5 was configured to allow the length in the first direction to be changed, but the invention is not limited to this configuration. The cover 5 may be configured so that the length in the first direction cannot be changed, for example, as shown in Figure 19.

[0102] In the above embodiment, the cover variable section 501 was composed of three types of variable connecting members 5010: an upper variable connecting member 5010, a lower variable connecting member 5010, and a middle variable connecting member 5010. However, the configuration is not limited to this. The cover variable portion 501 of the above embodiment may consist of, for example, two types of variable connecting members 5010, one arranged on one side in the second direction and the other on the other side in the second direction, or it may consist of only one type of variable connecting member 5010 formed to extend along the entire length of the cover 5 in the second direction.

[0103] In the above embodiment, the cover variable section 501 of the cover 5 was configured to change its length by combining a plurality of variable connecting members 5010 in a first direction, but it is not limited to this configuration. The cover variable section 501 of the cover 5 may, for example, be configured to change its length by sliding using a nested structure.

[0104] In the above embodiment, the pair of retaining members 4 were configured to be spaced apart from each other in the first direction, and fixed to the installation site in a state where the other retaining member 4 was rotated in the circumferential direction around an axis extending in the second direction relative to the first retaining member 4 and reversed. However, the configuration is not limited to this.

[0105] The pair of retaining members 4 may be configured to be fixed to the installation site with a gap between them in the first direction, as shown in Figures 21(a) and 21(b), and with the other retaining member 4 reversed in the circumferential direction around the axis extending in the first direction relative to the other retaining member 4.

[0106] Furthermore, the pair of retaining members 4 may be configured to be fixed to the installation site with a gap between them in the first direction, as shown in Figures 22(a) and 2(b), and with the other retaining member 4 reversed in the circumferential direction around an axis extending in the third direction relative to the first retaining member 4.
