[0001] The present invention relates to a through-member set that can be inserted into a wall through-hole that separates the indoor and outdoor spaces for collectively passing, for example, the pipes and drain hoses of an air conditioner.

Background Art

[0002] Conventionally, a substantially cylindrical through-sleeve configured to be insertable into a through-hole provided in a wall that separates the indoor and outdoor spaces for passing pipe members that connect an indoor unit and an outdoor unit of an air conditioner, a drain hose for draining drain water generated in the indoor unit to the outside, etc. is known.

[0003] When constructing such a conventional through-sleeve, usually, in order to prevent the intrusion of rainwater or the like into the indoor side and the backflow of drain water into the indoor side, a predetermined downward gradient is provided in the through-hole formed in the wall, and the through-sleeve is arranged along the downward gradient.

[0004] Further, such a conventional through-sleeve is composed of a substantially cylindrical sleeve body that is inserted into the through-hole with the above-mentioned predetermined downward gradient, and a flange member whose front end side can be inserted into the opening on the indoor side of the sleeve body and a flange portion is formed on the rear end side.

[0005] Engagement holes are formed in the upper and lower parts of the outer peripheral wall on the opening side of the sleeve body, and engagement claws are formed at positions corresponding to the engagement holes in the upper and lower parts of the outer peripheral wall on the front end side of the flange member.

[0006] With the above configuration, the flange member inserted into the opening of the sleeve body can be angle-adjusted with respect to the sleeve body by the engagement claws formed on the upper part of the flange member moving inside the engagement hole formed as a long hole in the upper part of the sleeve body with the engagement part of the engagement hole and the engagement claw formed in each lower part as a fulcrum.

[0007] When installing such conventional through-sleeves into a wall, the preparatory step involves rotating the flange member relative to the sleeve body to adjust its angle to correspond to the predetermined downward slope of the wall penetration hole, before installing it into the wall penetration hole. [Overview of the project] [Problems that the invention aims to solve]

Mode for Carrying Out the Invention

[0018] Hereinafter, as an embodiment of the through-member set of the present invention, a through-member set for attaching to a wall through-hole formed in a wall separating the indoor and outdoor spaces for collectively passing the pipes and drain hoses of an air conditioner, etc. will be described with reference to the drawings.

[0019] First, the through-member set 1 will be specifically described with reference to FIGS. 1 to 5.

[0020] FIG. 1 is an exploded perspective view of the through-member set 1 of the present embodiment.

[0021] Figure 2 is a schematic longitudinal cross-sectional view showing the through-member set 1 shown in Figure 1 installed in a wall through-hole.

[0022] Figure 3 is an enlarged side view of the connecting portion of the through-member set 1.

[0023] The through member set 1 of this embodiment is as shown in Figures 1 and 2,

[0024] (1) A cylindrical first sleeve member 100 (see Figures 1 and 2) that can be inserted into a wall penetration hole 11 (see Figure 2) formed in the wall 10 separating the indoor 10in and the outdoor 10out,

[0025] (2) A second sleeve member 200 having a flange portion 210 on one end (the side exposed to the interior 10in side when the through member set 1 is installed in the wall through hole 11) and a connecting cylindrical portion 220 on the other end that can be rotatably connected to the interior end 101a of the first sleeve member 100, It is composed of.

[0026] As shown in Figure 2, the wall penetration hole 11 in this embodiment is given a predetermined downward slope (see inclination angle θ in Figure 2) relative to the vertically installed wall 10 in order to prevent rainwater and the like from entering the interior 10in side and to prevent drain water from flowing back into the interior 10in side.

[0027] Furthermore, while the first sleeve member 100 and the second sleeve member 200 are molded from a synthetic resin mainly composed of polypropylene, they are not limited to this. For example, the first sleeve member 100 and the second sleeve member 200 may be molded from a synthetic resin mainly composed of polyethylene or polyvinyl chloride, etc.

[0028] Furthermore, when the first sleeve member 100 is inserted into the wall penetration hole 11 and viewed from the interior 10in side, a pair of left and right side communication holes 110L and 110R (see Figures 1 to 5) are provided on both the left and right sides of the interior end 101a of the first sleeve member 100, and a roughly square-shaped lower communication hole 120 is provided on the lower side of the interior end 101a of the first sleeve member 100 (see Figures 1 to 5).

[0029] The left and right pair of side communication holes 110L and 110R are formed, in a side view, generally along a circular arc 110a with radius R1 centered on the central part 121 of the lower communication hole 120 (see Figure 5).

[0030] Furthermore, multiple protrusions 112 and multiple recesses 113 are alternately and continuously formed on the upper edge 111 of the pair of left and right side communication holes 110L and 110R, which are roughly arc-shaped (see Figures 3 and 5).

[0031] Here, Figure 4(a) is a side view of the second sleeve member 200 seen from the right side, and Figure 4(b) is a bottom view of the second sleeve member 200 seen from below.

[0032] Figure 5 is a partial longitudinal cross-sectional view of the first sleeve member 100, and is an enlarged partial longitudinal cross-sectional view showing the indoor end 101a side.

[0033] The shapes and numbers of the protrusions 112 and recesses 113 shown in Figures 3 and 5 are merely examples and are not limited to them. For example, the number of protrusions 112 and recesses 113 shown in Figures 3 and 5 may be fewer or more than those shown.

[0034] Furthermore, when the through member set 1 is inserted into the wall through hole 11 and viewed from the interior 10in side, the connecting cylindrical portion 220 of the second sleeve member 200 is provided with a pair of substantially cylindrical engaging pins 230L and 230R (see Figures 1 to 4(b)) on both the left and right sides, which can be inserted into the left and right side communication holes 110L and 110R of the first sleeve member 100 to engage with them. In addition, the lower side of the connecting cylindrical portion 220 of the second sleeve member 200 is provided with a downwardly protruding lower projection 240 that can be fitted into the lower communication hole 120 of the first sleeve member 100 (see Figures 1 to 4(b)).

[0035] Furthermore, the pin base 231 on which the left and right pair of engagement pins 230L and 230R of the second sleeve member 200 are erected has notches 232 formed on its upper and lower sides when viewed from the side (see Figure 4(a)). As a result, by pressing the tips of the left and right pair of engagement pins 230L and 230R toward the center of the connecting cylindrical portion 220, the pin base 231 moves toward the center of the connecting cylindrical portion 220, so that the connecting cylindrical portion 220 of the second sleeve member 200 can be easily inserted into the indoor end 101a of the first sleeve member 100.

[0036] Furthermore, the notch depth 232D (see Figure 3) of the notch 232 is set such that even when the second inclination angle Φ (see Figure 3), which will be described later, is adjusted to its maximum angle, the opening of the notch 232 is closed by the indoor end 101a of the first sleeve member 100.

[0037] As a result, even when the second inclination angle Φ (see Figure 3) is adjusted to the maximum angle during installation of the through-member set 1 of this embodiment into the wall through-hole 11, it is possible to prevent moisture, dust, etc. present in the gap inside the wall 10 from entering the room 10in through the opening of the notch 232.

[0038] In this embodiment, the rear end edge 231a (see Figure 3) of the pin base 231 is described as being formed so as not to protrude rearward from the outdoor end edge 221 (see Figure 3) of the connecting cylindrical portion 220 of the second sleeve member 200, but the embodiment is not limited to this. That is, even when the second inclination angle Φ (see Figure 3) is adjusted to the maximum angle, the rear end edge 231a of the pin base 231 may be configured to protrude rearward so that the pair of left and right side communication holes 110L and 110R are closed by the outer surface of the pin base 231. This prevents moisture, dust, etc. present in the gap inside the wall 10 from entering the room 10in through the pair of left and right side communication holes 110L and 110R when the second inclination angle Φ (see Figure 3) is adjusted to the maximum angle during installation of the through member set 1 of this embodiment into the wall penetration hole 11.

[0039] Furthermore, the lower projection base 241 on which the lower projection 240 of the second sleeve member 200 is formed has notches 242 formed on both its left and right sides (see Figure 4(b)). As a result, by pressing the lower surface of the lower projection 240 toward the center of the connecting cylindrical portion 220, the lower projection base 241 moves toward the center of the connecting cylindrical portion 220, so that the lower projection 240 of the second sleeve member 200 can be easily fitted and inserted into the lower communication hole 120 of the indoor end 101a of the first sleeve member 100.

[0040] Furthermore, when adjusting the second inclination angle Φ (see Figure 3) of the inner surface of the flange portion 210 with respect to a plane perpendicular to the central axis 100a of the first sleeve member 100, corresponding to the predetermined inclination angle θ (see Figure 2) described above, by fitting the lower projection 240 of the second sleeve member 200 into the lower communication hole 120 of the first sleeve member 100 and rotating the second sleeve member 200 in the direction of arrow A (see Figure 3) using the lower projection 240 as a pivot point, the upper surface 220a of the connecting cylindrical portion 220 is formed to be curved toward the center to such an extent that the upper surface 220a of the connecting cylindrical portion 220 does not interfere with the upper part 101a1 (see Figure 5) of the inner peripheral wall of the indoor end 101a of the first sleeve member 100, thereby preventing the above rotation from being hindered.

[0041] Furthermore, the first sleeve member 100 and the second sleeve member 200 are configured such that the lower projection 240 of the second sleeve member 200 is fitted into the lower communication hole 120 of the first sleeve member 100, and the second sleeve member 200 is rotated in the direction of arrow A (see Figure 3) using the lower projection 240 as a pivot point, thereby moving the pair of left and right engaging pins 230L and 230R along the inside of the pair of left and right side communication holes 110L and 110R, thereby adjusting the second inclination angle Φ described above. In other words, when adjusting the second inclination angle Φ to a desired angle, the upper surfaces 230a (see Figure 4(a)) of the pair of left and right engaging pins 230L and 230R contact (abut) adjacent protrusions 112 formed on the upper edges 111 of the pair of left and right side communication holes 110L and 110R with a predetermined set pressure, and are positioned by the recesses 113 located between them, thereby restricting movement by weak external forces.

[0042] With the above configuration, the second inclination angle Φ can be adjusted by fitting the lower projection 240 of the second sleeve member 200 into the lower communication hole 120 of the first sleeve member 100, and using the lower projection 240 as a pivot point, rotating the second sleeve member 200 in the direction of arrow A (see Figure 3), thereby moving the pair of left and right engaging pins 230L and 230R along the inside of the pair of left and right side communication holes 110L and 110R. The adjusted angle (see the second inclination angle Φ in Figure 3) is maintained in the recess 113 located between the protrusions 112 to which the pair of left and right engaging pins 230L and 230R are positioned.

[0043] As a result, the adjusted angle (see the second inclination angle Φ in Figure 3) is maintained at the contact position with the protrusion 112, and the second sleeve member 200 will not rotate unless a force greater than the set is applied to rotate it. Therefore, if an external force greater than the set is not applied to the second sleeve member 200 during construction, it is possible to prevent the phenomenon of the adjusted angle easily changing due to easy displacement.

[0044] Furthermore, the wall penetration hole 11 in the above embodiment is an example of a wall penetration hole of the present invention. Also, the first sleeve member 100 in the above embodiment is an example of a first cylindrical member of the present invention, and the second sleeve member 200 in the above embodiment is an example of a second cylindrical member of the present invention. Furthermore, the pair of left and right side communication holes 110L and 110R in this embodiment are an example of a hole portion of the present invention, and the pair of left and right engaging pins 230L and 230R in this embodiment are an example of an engaging projection of the present invention. Furthermore, the upper side edge portion 111 of the pair of left and right side communication holes 110L and 110R in this embodiment is an example of a hole portion edge of the present invention, and the convex portion 112 in this embodiment is an example of a convex portion of the present invention.

[0045] An example of installation of the through-member set 1 of this embodiment into the wall through-hole 11 is as follows:

[0046] First, as a preparatory step, the worker rotates the second sleeve member 200 in the direction of arrow A (see Figure 3) relative to the first sleeve member 100 to match the predetermined downward slope (see inclination angle θ in Figure 2) of the wall penetration hole 11 formed in the wall 10, and adjusts the angle so that the second inclination angle Φ (see Figure 3) roughly coincides with the inclination angle θ of the wall penetration hole 11.

[0047] In other words, even when the connecting cylindrical portion 220 of the second sleeve member 200 is inserted into the indoor end portion 101a of the first sleeve member 100 and is in a state where it can rotate with the lower projection portion 240 as a pivot point, as described above, rotation with a weak force is restricted by the resistance generated when the upper surfaces 230a (see Figure 4(a)) of the pair of left and right engaging pins 230L, 230R abut against the protrusions 112 formed on the upper edges 111 of the pair of left and right side communication holes 110L, 110R. Therefore, in order for an operator to adjust the angle of the second inclination angle Φ, movement becomes possible by applying a force greater than the set amount to the second sleeve member 200 and rotating it, and the left and right pair of engaging pins 230L, 230R can be positioned in any recess 113 between adjacent protrusions 112.

[0048] Next, the worker inserts the through-member set 1, whose second inclination angle Φ has been adjusted, into the wall penetration hole 11 of the wall 10 from the room 10in side.

[0049] As a result, as described above, in the through member set 1 of this embodiment, unless an external force exceeding the set value is applied to the second sleeve member 200 during construction, it will not easily shift position and the adjusted second inclination angle Φ will not easily change. Therefore, the entire inner circumference 210a (see Figures 2 and 4(a)) of the flange portion 210 of the second sleeve member 200 can be installed without creating a gap between it and the indoor surface 10a (see Figure 2) of the wall 10 on the indoor side 10in.

[0050] Furthermore, the portion of the first sleeve member 100 that protrudes towards the outdoor side 10out, specifically the outdoor end 101b, can be cut as appropriate using the pre-provided cutting marks 102 (see Figure 1).

[0051] From the above, according to the through member set 1 of this embodiment, if an external force exceeding the set value is not applied to the second sleeve member 200 during construction, it will not easily shift position and the adjusted second inclination angle Φ will not easily change. Therefore, it is possible to prevent a gap from forming between the entire inner surface 210a of the flange portion 210 (see Figures 2 and 4(a)) and the indoor surface 10a of the wall 10 (see Figure 2), and the problem of reduced construction accuracy is unlikely to occur.

[0052] In the above configuration, the thickness of the left and right pair of engaging pins 230L and 230R can be easily increased by covering them with, for example, silicone tubes of different thicknesses. This makes it easy to increase the resistance generated when the left and right pair of engaging pins 230L and 230R contact the protrusions 112 formed in the left and right pair of side communication holes 110L and 110R.

[0053] In the above embodiment, a case was described in which multiple protrusions 112 and multiple recesses 113 are alternately and continuously formed on the upper edge 111 of the pair of left and right side communication holes 110L and 110R (see Figures 3 and 5). However, the invention is not limited to this, and for example, the edges of the pair of left and right side communication holes 110L and 110R may not have any protrusions or recesses formed on them. Compared to the conventional configuration in which the lower engagement hole of the sleeve body is used as a pivot point and position adjustment is performed only by the upper engagement hole, in this case, a pair of left and right side communication holes 110L and 110R that engage with a pair of left and right engagement pins 230L and 230R are provided on both the left and right sides of the first sleeve member 100. As a result, a larger resistance is generated due to the increased number of engagement points, making it less likely for misalignment to occur and reducing the accuracy of construction.

[0054] Furthermore, in the above embodiment, the case in which the first engaging portion of the present invention is a pair of left and right side communication holes 110L, 110R that are substantially arc-shaped (see Figures 1 to 3 and 5) was described, but the shape of the first engaging portion is not limited to this, and for example it may be rectangular, or the rectangular shape may be formed horizontally with respect to the central axis 100a (see Figure 2) in a side view, or it may be formed at an angle, in short, as long as the first engaging portion that engages with the second engaging portion is provided on both the left and right sides of the first cylindrical member.As a result, compared to the conventional configuration in which the position adjustment is performed only by the upper engaging hole with the lower engaging hole of the sleeve body as the pivot point, the first engaging portion that engages with the second engaging portion is provided on both the left and right sides of the first cylindrical member, so that a larger resistance is generated due to the larger number of engaging portions, making it less likely for positional misalignment to occur and reducing the accuracy of construction.

[0055] Furthermore, in the above embodiment, the first engaging portion of the present invention was described as a pair of left and right side communication holes 110L, 110R (see Figures 1 to 3 and 5) that are substantially arc-shaped, and the second engaging portion of the present invention was described as a pair of left and right engaging pins 230L, 230R. However, the invention is not limited to this, and for example, the first engaging portion may be a hole, and the second engaging portion may be an engaging projection that can engage with the hole, and the hole may be formed such that it approaches the pivot point (see reference numeral 240 in Figure 3) as it moves from one end side of the second cylindrical member (see indoor end 101a in Figure 2) to the other end side (see outdoor end 101b in Figure 2).

[0056] Furthermore, in the above embodiment, the first engaging portion of the present invention was described as a pair of left and right side communication holes 110L, 110R (see Figures 1 to 3 and 5) that are substantially arc-shaped, and the second engaging portion of the present invention was described as a pair of left and right engaging pins 230L, 230R. However, the invention is not limited to this, and for example, the first engaging portion may be a pair of left and right recesses formed on both the left and right sides of the inner wall surface of the first cylindrical member, and the second engaging portion may be a pair of left and right engaging protrusions that can engage with the recesses.

[0057] Furthermore, although the above embodiment described the case in which the second engaging portion of the present invention is a pair of substantially cylindrical engaging pins 230L and 230R, it is not limited to this, and for example, the pair of engaging pins 230L and 230R may be rectangular prisms or any other polygonal shape in cross-section. Also, instead of substantially cylindrical engaging pins 230L and 230R, for example, hemispherical engaging protrusions may be used.

[0058] Furthermore, in the above embodiment, a case was described in which a plurality of protrusions 112 and a plurality of recesses 113 are alternately and continuously formed on the upper edge 111 of the left and right pair of side communication holes 110L and 110R (see Figures 3 and 5). However, the invention is not limited to this, and for example, a plurality of protrusions 112 may be provided on the lower edge of the left and right pair of side communication holes 110L and 110R.

[0059] Furthermore, in the above embodiment, a case was described in which multiple protrusions 112 and multiple recesses 113 are alternately and continuously formed on the upper edge 111 of the left and right side communication holes 110L and 110R (see Figures 3 and 5). However, the invention is not limited to this, for example, one protrusion 112 may be formed on the upper edge 111 or the lower edge of the left and right side communication holes 110L and 110R, or one protrusion 112 may be formed on the upper edge 111 and the lower edge of the left and right side communication holes 110L and 110R at different or opposing positions, or one protrusion 112 may be formed on one edge and multiple protrusions 112 may be formed on the other edge.

[0060] Furthermore, in the above embodiment, a case was described in which a plurality of protrusions 112 and a plurality of recesses 113 are alternately and continuously formed on the upper edge 111 of the left and right pair of side communication holes 110L and 110R (see Figures 3 and 5). However, this is not limited to this, for example, a plurality of protrusions 112 may be provided on both the upper edge 111 and the lower edge of the left and right pair of side communication holes 110L and 110R.

[0061] Furthermore, in the above embodiment, a case was described in which a plurality of protrusions 112 and a plurality of recesses 113 are alternately and continuously formed on the upper edge 111 of the left and right side communication holes 110L and 110R (see Figures 3 and 5). However, this is not limited to this, for example, a single protrusion 112 may be provided on both the upper edge 111 and the lower edge of the left and right side communication holes 110L and 110R.

[0062] Furthermore, in the above embodiment, the pin base 231 on which the left and right pair of engaging pins 230L and 230R are erected has notches 232 formed on its upper and lower sides in a side view (see Figure 4(a)), but the embodiment is not limited to this, and for example, the notches 232 may not be formed.

[0063] Furthermore, although the above embodiment describes the case where the lower communication hole 120 of the first sleeve member 100 is a through hole, the invention is not limited to this, and for example, the lower wall surface side of the first sleeve member 100 may be provided with a recess into which the lower projection 240 of the second sleeve member 200 can be fitted and inserted, instead of a through hole.

[0064] Furthermore, in the above embodiment, the case in which the through-member set 1 is applied to a member for passing air conditioner piping, drain hoses, etc. through together was described, but it is not limited to this and may be applied to other uses, for example, a member for passing other pipes or television antenna cables.

[0065] Furthermore, although the above embodiment describes the case where the wall penetration hole 11 has a predetermined downward slope (see the inclination angle θ in Figure 2), the invention is not limited to this case, and the penetration member set 1 of this embodiment can also be applied when the wall penetration hole 11 is provided horizontally. In this case, the penetration member set 1 can be arranged horizontally within the wall penetration hole 11, or, if the diameter of the wall penetration hole 11 is sufficiently large compared to the outer diameter of the penetration member set 1, the penetration member set 1 can be installed on a downward slope. In this case as well, the same effects as described above can be obtained.

[0066] Next, we will explain the through-member set 1 in more detail, mainly referring to Figures 6 to 14.

[0067] As shown in Figure 6, which is an explanatory diagram (part one) of the through-member set 1 of this embodiment, it is conceivable that the entire surface of the ring plate surface Sr from the inner periphery of the ring to the outer periphery of the ring is a flat plate surface Σ. However, as shown in Figures 7 and 8, which are explanatory diagrams (parts two and three) of the through-member set 1 of this embodiment, it is also conceivable that a step δ is provided on the outer periphery of the flat plate surface Σ.

[0068] As shown in Figure 7, it is possible that the center of the adhesive tape member 500 coincides with the center of the flange portion 210. However, as shown in Figure 9, which is an explanatory diagram (fourth) of the through-member set 1 of the embodiment, it is also possible that the center of the adhesive tape member 500 is offset upward from the center of the flange portion 210.

[0069] It is desirable that the adhesive tape member 500 attached to the flat surface Σ of the plate does not extend beyond the area above the step δ.

[0070] In any case, it is essential that the airtightness is improved by the adhesive tape material 500 so that condensation caused by air leakage from gaps is less likely to occur.

[0071] As shown in Figure 10, which is an explanatory diagram (part one) of the adhesive tape member 500 of the through member set 1 of this embodiment, the adhesive tape member 500 is attached to the ring plate surface Sr on the other end side of the flange portion 210, so that it is firmly adhered to the wall 10 with its adhesive surface Sa. Therefore, the occurrence of a gap between the through member set 1 inserted into the wall through hole 11 and the wall 10 is suppressed.

[0072] An adhesive tape member 500, which adheres to the wall 10 with its adhesive surface Sa, is attached to the ring plate surface Sr on the other end side of the flange portion 210.

[0073] A release sheet member 600, which is peeled off when the adhesive tape member 500 is adhered to the wall 10, is attached to the adhesive surface Sa in a way that allows it to be peeled off.

[0074] As shown in Figure 11, which is an explanatory diagram (part two) of the adhesive tape member 500 of the through-member set 1 of this embodiment, when the adhesive tape member 500 is adhered to the wall 10, the release sheet member 600 attached to the adhesive surface Sa is peeled off, so the unintended adhesive phenomenon of the adhesive tape member 500 hardly occurs at all during stages such as storage and sales of the through-member set 1.

[0075] The shape of the adhesive tape member 500 is approximately a ring sheet shape, extending around the entire circumference of the flange portion 210.

[0076] Since the shape of the adhesive tape member 500 extends around the entire circumference of the flange portion 210 ring, the occurrence of gaps in all directions is suppressed.

[0077] A ring-radial cut 610 is formed in the release sheet member 600.

[0078] Since the ring has radial cuts 610, the worker can easily peel off the release sheet member 600 attached to the adhesive surface Sa. Of course, it is conceivable that there be multiple cuts 610 as described above, but as shown in Figures 12 and 13, which are explanatory diagrams (parts three and four) of the adhesive tape member 500 of the through member set 1 of this embodiment, it is also conceivable that there be zero or one cut 610. The number of cuts 610 should be appropriately selected considering the manufacturing cost of the release sheet member 600 and the ease of the peeling operation.

[0079] The adhesive tape member 500 is attached to at least the outer edge of the ring on the ring plate surface Sr.

[0080] Since the adhesive tape member 500 is attached to the outer edge of the ring, even if the insertion position of the penetration member set 1 is misaligned due to the size of the wall penetration hole gap G, which is the play between the penetration member set 1 inserted into the wall penetration hole 11 and the wall penetration hole 11, the adhesive tape member 500 can reliably contact the wall 10 with its adhesive surface Sa.

[0081] The ring width W=Wd of the adhesive tape member 500 on the lower side is greater than the ring width W=Wu on the upper side.

[0082] As shown in Figure 14, which is an explanatory diagram (fifth) of the adhesive tape member 500 of the through member set 1 of this embodiment, the ring width Wd on the lower side is larger than the ring width Wu on the upper side, and the ring width Wu on the upper side is set not to be excessively large. Therefore, even when the size of the wall penetration hole gap G due to the weight of the through member set 1 is relatively large on the upper side, partial exposure of the adhesive tape member 500 from the wall penetration hole 11 is unlikely to occur, and the occurrence of useless, non-functional portions of the adhesive tape member 500 is suppressed.

[0083] The ring width W gradually increases from the top to the bottom.

[0084] Since the ring width W gradually increases from the top to the bottom, the simple shape of the adhesive tape member 500, which facilitates tape cutting and other processes, reduces partial exposure of the adhesive tape member 500 from the wall penetration hole 11 while ensuring reliable contact between the adhesive tape member 500 and the wall 10.

[0085] The first sleeve member 100 and the second sleeve member 200 may be integrally molded. [Industrial applicability]

[0086] The through-member set in the present invention can suppress the occurrence of gaps between the through-member set inserted into a wall through-hole and the wall, and is useful for use as a through-member set that can be inserted into a wall through-hole. [Explanation of Symbols]
