Japanese Utility Model Publication No. 57-174681

  By the way, when performing the work of installing the opening frame in the opening of the building, a force acts in the direction in which the end surface of the opening frame separates from the joining surface of the vertical frame by the transport method when transporting the opening frame. It is conceivable that a force acts in the direction in which the end face of the horizontal frame separates from the joint surface of the vertical frame due to a dimensional error of an element constituting the opening. If the horizontal frame is displaced in the direction of separating from the vertical frame in this way, a gap may be generated between the end face of the horizontal frame and the sealing material. If such a gap is generated, the water stop performance cannot be ensured, and there is a risk of allowing rainwater or the like to enter.

  Note that, here, the joining structure between the end face of the horizontal frame and the joining face of the vertical frame has been described, but the same applies to the joining structure in which a sealing material is interposed between the end face of the vertical frame and the joining face of the horizontal frame. Needless to say, there is a problem, and the same problem may occur in the joining structure of the components of the shoji, not limited to the opening frame.

  In view of the above situation, the present invention provides a joint structure for a shape member that can achieve good water stoppage performance even when the end face of one shape member is displaced in a direction away from the joint surface of the other shape member. And to provide joinery.

Therefore, there is no possibility that the swelling material of the sealing material expands when forming the joint structure and hinders the formation of the joint structure. And since the swelling layer is formed on the surface of the rubber layer, when coming into contact with the end face of the first profile, the swelling material of the swelling layer is exposed at the boundary with the first profile, Even if the end face of the first profile is displaced in a direction away from the joint surface of the second profile and a gap is generated, the swelling material that constitutes the surface of the sealing material that contacts the end face of the first profile Since the water entering the gap is absorbed and expanded, it is possible to suppress water from passing through the gap and ensure water stopping performance.

According to the present invention, in the joint structure of the above-described profiles, the sealing material includes a surface layer that covers a surface of the swelling layer.

Further , the shape joining structure according to the present invention is a shape joining structure in which the end surface of the first shape is joined in a state where the sealing material is interposed between the joining surfaces of the second shape, and the sealing material Is formed by containing a swelling material made of a water-absorbent resin at least in a portion that is pressed and deformed by the first profile, and a swelling layer formed by kneading the swelling material with an unvulcanized rubber member; And a degassing layer for releasing the gas contained in the swelling layer and adjacent to the swelling layer.

According to this invention, water vapor or the like absorbed by the swelling material during the production process of the swelling layer can be released to the outside through the degassing layer.

Moreover, the present invention is characterized in that, in the joining structure of the shape members, the degassing layer is a base material of the sealing material.

According to the present invention, water vapor or the like absorbed by the swelling material during the production process of the swelling layer can be released to the outside through the base material of the sealing material.

Further, in the joining structure of the above-described profiles, the sealing material includes a rubber layer formed on the surface of the swelling layer opposite to the surface adjacent to the base material and made of an unvulcanized rubber member. It is characterized by that.

Moreover, the present invention is characterized in that, in the joining structure of the above-mentioned profiles, the base material is composed of a non-woven fabric or a cold water bottle .

According to the present invention, in the joint structure of the above-described profiles, the end surface of the first profile is a small edge formed by cutting an extruded profile composed of a metal material, a resin material, or a composite material of a metal and a resin. It is characterized by being.

According to the present invention, since the end face of the first profile is a small edge, the end face has a number of sharp portions. Therefore, when the first shape member presses the sealing material, the end surface of the first shape material can damage the surface of the sealing material and can be easily broken.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a shape joining structure and a fitting according to the present invention will be described in detail with reference to the accompanying drawings.

<Embodiment 1>
FIG. 1 is an external view schematically showing a joinery to which a joining structure of shapes according to Embodiment 1 of the present invention is applied, that is, the joinery according to Embodiment 1 of the present invention viewed from the indoor side. is there. The joinery illustrated here is called a sliding window in which the opening frame 10 includes two left and right shojis 20 and the two shojis 20 are opened and closed in the left-right direction with respect to the opening frame 10.

  The opening frame 10 forms a rectangular opening formed by four-frames the upper frame 11, the lower frame (first shape member) 12, and the pair of left and right vertical frames 13 and 14. The upper frame 11, the lower frame 12, and the pair of left and right vertical frames 13 and 14 are extruded shapes made of a metal material such as aluminum, for example. Such an opening frame 10 follows the opening edge of the upper frame 11, the lower frame 12, and the pair of left and right vertical frames 13, 14 with respect to the housing opening 2 formed in the housing 1 such as a wall of a house. It is attached as follows.

  The shoji 20 is obtained by holding a face material 25 inside a scissors formed by assembling an upper scissors 21, a lower scissors 22, and a pair of left and right vertical scissors 23, 24, respectively. The upper rod 21, the lower rod 22, and the pair of left and right vertical rods 23, 24 are extruded shapes made of a metal material such as aluminum.

  By the way, between the left end surface 12a of the lower frame 12 which comprises the opening frame 10 of the said fitting, and the lower side joining surface 13a of the left side vertical frame (2nd shape material, hereafter also called the left vertical frame) 13 As shown in FIG. 2, a sealing material 30 is interposed. In the example of FIG. 2, only the space between the left end surface 12 a of the lower frame 12 and the lower joint surface 13 a of the left vertical frame 13 is shown, but in the joinery described above, the right end surface 12 b of the lower frame 12 and Between the lower joint surface 14a of the right vertical frame (hereinafter also referred to as right vertical frame) 14, between the left end surface 11a of the upper frame 11 and the upper joint surface 13b of the left vertical frame 13, and the upper frame 11 is also interposed between the right end surface 11b of 11 and the upper joint surface 14b of the right vertical frame 14.

  Here, the left end surface 12a and the right end surface 12b of the lower frame 12 and the left end surface 11a and the right end surface 11b of the upper frame 11 are formed by cutting an extruded shape of a metal material in a direction perpendicular to the longitudinal direction. Petite. Further, it is preferable that the fore edge is not subjected to chemical surface treatment such as anodizing or physical surface treatment such as sanding.

  As schematically shown in FIG. 3, the sealing material 30 has a sheet-like form. The sealing material 30 has a rubber layer 32 having an unvulcanized rubber member such as butyl rubber formed on the front and back surfaces of a base material 31 made of, for example, a non-woven fabric or a cold koji, and a swelling material 33 on the surface of one rubber layer 32. Is applied and formed. The swelling material 33 is made of a super absorbent polymer (SAP) and has a function of absorbing and gelling a large amount of water and retaining the water. Such a swelling material 33 is applied to the surface of one rubber layer 32 so as to constitute one surface of the sealing material 30.

  When the upper frame 11, the lower frame 12, and the pair of left and right vertical frames 13, 14 are quadrilaterally framed, as shown in FIG. 4, the left end surface 12 a of the lower frame 12 is inserted into the left vertical frame 13 via the sealing material 30. It joins to the lower joining surface 13a. At this time, the seal material 30 interposed between the left end surface 12a of the lower frame 12 and the lower joint surface 13a of the left vertical frame 13 is compressed and deformed by being pressed by the lower frame 12. In addition, between the right end surface 12b of the lower frame 12 and the lower joint surface 14a of the right vertical frame 14, between the left end surface 11a of the upper frame 11 and the upper joint surface 13b of the left vertical frame 13, and the upper frame. The sealing material 30 interposed between the right end surface 11b of the eleventh and the upper joint surface 14b of the right vertical frame 14 is similarly compressed and deformed.

  When performing the operation of installing the opening frame 10 having the above-described joining structure in the housing opening 2 of the housing 1, the left end surface 12 a is left to the lower frame 12 by the transportation method when the opening frame 10 is transported. The left end surface 12a of the lower frame 12 is set to the left vertical due to a force acting in a direction away from the lower joint surface 13a of the vertical frame 13, or due to a dimensional error of an element constituting the housing opening 2. When a force is applied in a direction away from the lower joint surface 13a of the frame 13, a gap is formed between the left end surface 12a of the lower frame 12 and the sealing material 30 and the swelling material 33 as shown in FIG. May occur.

  When a gap is formed in this way and water such as rainwater enters the gap, the swelling material 33 absorbs the water and expands as shown in FIG. Can be prevented from passing through the gap, and as a result, water stopping performance can be ensured.

  According to the joint structure according to the first embodiment as described above, a gap is generated between the left end surface 12a of the lower frame 12 and the sealing material 30 attached to the joint surface 13a of the left vertical frame 13. However, since the swelling material 33 constituting the surface of the sealing material 30, that is, the surface in contact with the left vertical frame 13, absorbs the water entering the gap and expands, thereby suppressing the passage of water through the gap. Thus, the water stop performance can be ensured, so that the water stop performance can be improved even if the left end surface 12a of the lower frame 12 is displaced in the direction away from the joint surface 13a of the left vertical frame 13. Can do.

  In particular, the left end surface 12a of the lower frame 12 and the like is a small edge formed by cutting an extruded shape of a metal material in a direction perpendicular to the longitudinal direction thereof, and is a chemical surface treatment such as alumite treatment or a file. Since no physical surface treatment such as scribing is applied, the left end surface 12a and the like have a number of sharp portions. Therefore, when the lower frame 12 or the like presses the sealing material 30, the left end surface 12 a or the like of the lower frame 12 or the like can easily damage the surface of the sealing material 30, thereby causing the surface swelling material. 33 can be expressed easily.

<Embodiment 2>
FIG. 7: is an external view which shows simply the case where the joinery to which the joining structure of the profile which is Embodiment 2 of this invention is applied, ie, the joinery which is Embodiment 2 of this invention, is seen from the indoor side. is there. The joinery illustrated here is a sliding window that includes two right and left shojis 50 in the opening frame 40 and moves the two shojis 50 to open and close in the left and right directions with respect to the opening frame 40.

  The opening frame 40 forms a rectangular opening formed by four-frames an upper frame 41, a lower frame (first profile) 42, and a pair of left and right vertical frames 43 and 44. The upper frame 41, the lower frame 42, and the pair of left and right vertical frames 43 and 44 are extruded shapes made of a metal material such as aluminum, for example. Such an opening frame 40 has an upper frame 41, a lower frame 42, and a pair of left and right vertical frames 43, 44 along the edge of the opening with respect to the housing opening 4 formed in the housing 3 such as a wall of a house. It is attached as follows.

  The shoji 50 is obtained by holding a face material 55 inside a scissors formed by assembling an upper scissors 51, a lower scissors 52, and a pair of left and right vertical scissors 53, 54, respectively. The upper rod 51, the lower rod 52, and the pair of left and right vertical rods 53 and 54 are extruded shapes made of a metal material such as aluminum.

  By the way, between the left end surface 42a of the lower frame 42 which comprises the opening frame 40 of the said fitting, and the joining surface 43a of the lower side of the left side vertical frame (2nd shape material, hereafter also called the left vertical frame) 43. As shown in FIG. 8, a sealing material 60 is interposed. In the example of FIG. 8, only the space between the left end surface 42 a of the lower frame 42 and the lower joint surface 43 a of the left vertical frame 43 is illustrated. Between the lower vertical joint surface 44a (hereinafter also referred to as the right vertical frame) 44, between the left end surface 41a of the upper frame 41 and the upper joint surface 43b of the left vertical frame 43, and the upper frame. A sealing material 60 having the same configuration is also interposed between the right end surface 41 b of 41 and the upper joint surface 44 b of the right vertical frame 44.

  Here, the left end surface 42a and the right end surface 42b of the lower frame 42 and the left end surface 41a and the right end surface 41b of the upper frame 41 are formed by cutting an extruded shape of a metal material in a direction perpendicular to the longitudinal direction. Petite. Further, it is preferable that the fore edge is not subjected to chemical surface treatment such as anodizing or physical surface treatment such as sanding.

  Such a sealing material 60 has a sheet-like form as schematically shown in FIG. The sealing material 60 has a rubber layer 62 having an unvulcanized rubber member such as butyl rubber formed on the front and back surfaces of a base material 61 made of, for example, a non-woven fabric or a cold koji, and a swelling material on the surface of one rubber layer 62. A swelling layer 63 in which 64 is kneaded with an unvulcanized rubber member is laminated and formed. The swelling material 64 is made of a super absorbent polymer (SAP) and has a function of absorbing and gelling a large amount of water and retaining the water.

  In such a sealing material 60, the ratio of the thickness of the swelling layer 63 to the total thickness is preferably 0.2 or more, and more preferably 0.2 to 0.5. When the thickness of the swelling layer 63 is 0.2 or more with respect to the total thickness of the sealing material 60, the swelling material 64 included in the swelling layer 63 when the sealing material 60 is pressed against the lower frame 42 and is compressed and deformed. Can be expressed in a sufficient amount.

  Such a sealing material 60 is manufactured as follows. First, as shown in FIG. 10 (a), the unvulcanized rubber member 65 for forming the rubber layer 62 is kneaded with other components 66, and as shown in FIG. 10 (b), the swelling layer An unvulcanized rubber member 65 for forming 63 and a swelling material 64 made of SAP are kneaded.

  Next, as shown in FIG. 11A, while the base material 61 such as a nonwoven fabric is conveyed between the pair of rollers 71 and 72, the unvulcanized rubber member 65 and the other base material 61 are provided on one surface of the base material 61. A rubber layer 62 is formed by applying a kneaded component 66. After forming the rubber layer 62 on one surface of the substrate 61 in this way, as shown in FIG. 11B, the substrate 61 having the rubber layer 62 formed on one surface between a pair of rollers 71 and 72 is formed. A rubber layer 62 is formed by applying a kneaded unvulcanized rubber member 65 and another component 66 to the other surface of the substrate 61 while being conveyed. Thereby, the rubber layer 62 is formed on both surfaces of the base material 61.

  Then, as shown in FIG. 11 (c), the unvulcanized rubber is formed on the surface of one rubber layer 62 while the base material 61 having the rubber layer 62 formed on both surfaces is conveyed between a pair of rollers 71 and 72. A material obtained by kneading the member 65 and the swelling material 64 is applied to form the swelling layer 63. The sealing material 60 is manufactured by cutting the swelling layer 63 thus formed into an appropriate size.

  In the sealing material 60 manufactured in this way, the swelling material 64 constituting the swelling layer 63 is kneaded with the unvulcanized rubber member 65 and thus does not appear on the surface.

  When the upper frame 41, the lower frame 42, and the pair of left and right vertical frames 43, 44 are quadrilaterally framed, as shown in FIG. 12, the left end surface 42 a of the lower frame 42 passes through the sealing material 60 and the left vertical frame 43. It is joined to the lower joining surface 43a. At this time, the seal member 60 interposed between the left end surface 42a of the lower frame 42 and the lower joint surface 43a of the left vertical frame 43 is compressed and deformed by being pressed by the lower frame 42. That is, the rubber layer 62 and the swelling layer 63 are compressively deformed. In addition, between the right end surface 42b of the lower frame 42 and the lower joint surface 44a of the right vertical frame 44, between the left end surface 41a of the upper frame 41 and the upper joint surface 43b of the left vertical frame 43, and the upper frame. The sealing material 60 interposed between the right end surface 41b of 41 and the upper joint surface 44b of the right vertical frame 44 is similarly compressed and deformed.

  As the sealing material 60 is compressed and deformed in this way, a part of the surface of the sealing material 60 is destroyed, that is, a part of the unvulcanized rubber member 65 of the swelling layer 63 is destroyed. That is, the swelling material 64 is exposed at the boundary portion with the lower frame 42.

  When performing the operation of installing the opening frame 40 having the above-described joining structure in the housing opening 4 of the housing 3, the left end face 42 a is left with respect to the lower frame 42 by the transport method when transporting the opening frame 40. The left end surface 42a of the lower frame 42 has a left vertical surface due to a force acting in a direction away from the lower joint surface 43a of the vertical frame 43, or due to a dimensional error of an element constituting the housing opening 4. If a force is applied in a direction away from the joint surface 43a on the lower side of the frame 43, a gap may be generated between the left end surface 42a of the lower frame 42 and the sealing material 60 as shown in FIG. is there.

  In this way, when a gap is generated and water such as rainwater enters the gap, the swelling material 64 that is exposed absorbs the water and expands in the joint structure as shown in FIG. Therefore, it is possible to suppress the water from passing through the gap, and as a result, it is possible to ensure water stopping performance.

  According to the joint structure according to the second embodiment as described above, there is a gap between the left end surface 42a of the lower frame 42 and the sealing material 60 attached to the joint surface 43a of the left vertical frame 43. In addition, since the swelling material 64 constituting the swelling layer 63 of the sealing material 60 absorbs the water entering the gap and expands, it is possible to suppress the passage of water through the gap and ensure the water stop performance. Thus, even if the left end surface 42a of the lower frame 42 is displaced in a direction away from the joint surface 43a of the left vertical frame 43, the water stop performance can be improved.

  In particular, since the swelling material 64 constituting the swelling layer 63 of the sealing material 60 is kneaded with the unvulcanized rubber member 65 and does not appear on the surface in a normal state, the sealing material 60 is used before the sealing material 60 is used for the joining structure. Even if moisture or the like adheres to the material 60, the swelling material 64 can be prevented from expanding. Therefore, there is no possibility that the swelling material 64 of the sealing material 60 expands to form the bonded structure when the bonded structure is formed. And, since the swelling material 64 is exposed to the boundary portion with the lower frame 42 due to the compressive deformation of the sealing material 60 at the time of forming the joint structure, as a result of absorbing the water entering the gap and expanding as described above, the gap is reduced. Water stopping performance can be improved by suppressing the passage of water. Thereby, the water stop performance can be made good while making the handleability of the sealing material 60 good.

  Further, the left end face 42a of the lower frame 42, etc. is a small edge formed by cutting an extruded shape of a metal material in a direction perpendicular to the longitudinal direction thereof, and is a chemical surface treatment such as alumite treatment or a file. Since no physical surface treatment such as scribing is applied, the left end face 42a and the like have a number of sharp portions. Therefore, when the lower frame 42 or the like presses the sealing material 60, the left end surface 42a or the like of the lower frame 42 or the like can damage the swelling layer 63 constituting the surface of the sealing material 60 and can be easily destroyed. Thereby, the swelling material 64 can be easily exposed from the swelling layer 63.

  The preferred embodiment 1 and embodiment 2 of the present invention have been described above, but the present invention is not limited to these, and various modifications can be made.

  In Embodiment 2 described above, the rubber layer 62 constituting the sealing material 60 is configured to contain the unvulcanized rubber member 65. However, in the present invention, the rubber layer constituting the sealing material is, for example, a synthetic material. It may be made of a rubber material or the like, and may be elastically deformed when pressed by the first shape member. Even in this case, when the sealing material is pressed by the first shape member and compressively deformed, a part of the unvulcanized rubber member of the swelling layer is destroyed, so that the swelling material appears at the boundary portion with the first shape member. The water stop performance can be improved.

  In the second embodiment described above, the swelling layer 63 having the swelling material 64 forms one surface of the sealing material 60. However, in the present invention, the sealing material is compressed and deformed by being pressed by the first profile. In this case, the swelling layer may not form the surface of the sealing material as long as the swelling material can be exposed at the boundary with the first shape member. That is, as shown in FIG. 15, the sealing material 80 has a sheet-like form. For example, the rubber layer 62 having an unvulcanized rubber member such as butyl rubber on the front surface and the back surface of the base material 61 made of a nonwoven fabric or the like. Further, a swelling layer 63 formed by kneading a swelling material 64 with an unvulcanized rubber member is laminated on the surface of one rubber layer 62, and a surface layer 81 by painting or coating is further formed on the surface of the swelling layer 63. May be formed.

  Also in the sealing material 80, the ratio of the thickness of the swelling layer 63 to the total thickness is preferably 0.2 or more, and more preferably 0.2 to 0.5. When the thickness of the swelling layer 63 is 0.2 or more with respect to the total thickness of the sealing material 80, the swelling layer is pressed when the sealing material 80 is compressed and deformed by being pressed by the first profile (the lower frame 42 or the like). A sufficient amount of the swelling material 64 contained in 63 can be exposed.

  In the second embodiment described above, the swelling layer 63 having the swelling material 64 forms one surface of the sealing material 60. However, in the present invention, the sealing material is compressed and deformed by being pressed by the first profile. In this case, the swelling layer may not form the surface of the sealing material as long as the swelling material can be exposed at the boundary with the first shape member. That is, as shown in FIG. 16, the sealing material 82 has a sheet-like form. For example, a swelling layer in which a swelling material 64 is kneaded with an unvulcanized rubber member on the surface of a base material 61 made of a nonwoven fabric or the like. 63, a rubber layer 62 having an unvulcanized rubber member such as butyl rubber is formed on the back surface of the substrate 61, and a rubber layer having an unvulcanized rubber member such as butyl rubber on the surface of the swelling layer 63 62 may be laminated.

  Also in the sealing material 82, the ratio of the thickness of the swelling layer 63 to the total thickness is preferably 0.2 or more, and more preferably 0.2 to 0.5. When the thickness of the swelling layer 63 is 0.2 or more with respect to the total thickness of the sealing material 82, the swelling layer 63 is pressed when the sealing material 82 is pressed against the first profile (the lower frame 42, etc.) and is compressed and deformed. A sufficient amount of the swelling material 64 contained in 63 can be exposed.

  In the second embodiment described above, the swelling layer 63 having the swelling material 64 forms one surface of the sealing material 60. However, in the present invention, the sealing material is compressed and deformed by being pressed by the first profile. In this case, the swelling layer may not form the surface of the sealing material as long as the swelling material can be exposed at the boundary with the first shape member. That is, as shown in FIG. 17, the sealing material 83 may be formed only of a swelling layer in which the swelling material 64 is kneaded with the unvulcanized rubber member.

  In the present invention, the sealing material may have the following configuration. That is, as shown in FIG. 18, the sealing material 84 has a sheet-like form. For example, a swelling layer in which a swelling material 64 is kneaded with an unvulcanized rubber member on the surface of a base material 61 made of a nonwoven fabric or the like. 63 may be laminated, and a rubber layer 62 having an unvulcanized rubber member such as butyl rubber may be formed on the back surface of the substrate 61. That is, the swelling layer 63 may be adjacent to the base material 61 as in the example shown in FIG.

  Also in the sealing material 84, the ratio of the thickness of the swelling layer 63 to the total thickness is preferably 0.2 or more, and more preferably 0.2 to 0.5. When the thickness of the swelling layer 63 is 0.2 or more with respect to the total thickness of the sealing material 84, the swelling layer is pressed when the sealing material 84 is compressed and deformed by being pressed by the first profile (the lower frame 42 or the like). A sufficient amount of the swelling material 64 contained in 63 can be exposed.

  According to such a configuration, water vapor or the like absorbed by the swelling material 64 during the manufacturing process of the swelling layer 63 can be released to the outside through the base material 61. Therefore, it can suppress that the water vapor | steam etc. which were absorbed by the swelling material 64 vaporize inside the sealing material 84, for example in a high temperature atmosphere. Here, the case where the swelling layer 63 and the base material 61 are adjacent to each other has been described. However, in the present invention, the swelling layer 63 and a degassing layer made of, for example, a nonwoven fabric may be adjacent to each other. And the substrate 61 are not necessarily adjacent to each other.

  In Embodiment 2 described above, when the left end surface 42a of the lower frame 42 presses the sealing material 60, the swelling layer 63 is divided as shown in FIG. 12, but in the present invention, it is shown in FIG. As described above, even in the region pressed against the lower frame 42, the deformation may be performed while the swelling layer 63 remains. As the sealing material 60 is compressed and deformed in this way, a part of the surface of the sealing material 60 is destroyed, that is, a part of the unvulcanized rubber member 65 of the swelling layer 63 is destroyed. That is, the swelling material 64 is exposed at the boundary portion with the lower frame 42.

  When performing the operation of installing the opening frame 40 having such a joint structure in the case opening 4 of the case 3, the left end surface 42 a of the left frame 42 is set to the left vertical frame 43 with respect to the lower frame 42 by the method of carrying the opening frame 40. The left end surface 42a of the left vertical frame 43 is formed with respect to the lower frame 42 due to a force acting in a direction away from the lower joint surface 43a or due to a dimensional error of an element constituting the housing opening 4 or the like. If a force is applied in a direction away from the lower joint surface 43a, a gap may be generated between the left end surface 42a of the lower frame 42 and the sealing material 60 as shown in FIG. In this way, when a gap is generated and water such as rainwater enters the gap, the swelling material 64 that is exposed absorbs the water and expands as shown in FIG. Therefore, it is possible to suppress the water from passing through the gap, and as a result, it is possible to ensure water stopping performance.

  In Embodiment 2 described above, when the left end surface 42a of the lower frame 42 presses the sealing material 60, the swelling layer 63 is divided as shown in FIG. 12, but in the present invention, only the swelling layer 63 is present. Alternatively, the base material 61 may be greatly compressed and deformed. As the sealing material 60 is compressed and deformed in this way, a part of the surface of the sealing material 60 is destroyed, that is, a part of the unvulcanized rubber member 65 of the swelling layer 63 is destroyed. That is, the swelling material 64 is exposed at the boundary portion with the lower frame 42.

  When performing the operation of installing the opening frame 40 having such a joint structure in the case opening 4 of the case 3, the left end surface 42 a of the left frame 42 is set to the left vertical frame 43 with respect to the lower frame 42 by the method of carrying the opening frame 40. The left end surface 42a of the left vertical frame 43 is formed with respect to the lower frame 42 due to a force acting in a direction away from the lower joint surface 43a or due to a dimensional error of an element constituting the housing opening 4 or the like. If a force is applied in a direction away from the lower joint surface 43a, a gap may be generated between the left end surface 42a of the lower frame 42 and the sealing material 60, as shown in FIG. In this way, when a gap is generated and water such as rainwater enters the gap, the swelling material 64 that is exposed as shown in FIG. 23 absorbs the water and expands. Therefore, it is possible to suppress the water from passing through the gap, and as a result, it is possible to ensure water stopping performance.

  Thus, when not only the swelling layer 63 but also the base material 61 is greatly compressed and deformed, the swelling layer 63 greatly enters the inside of the rubber layer 62 following the pressing of the lower frame 42, The overlapping width with the exposed swelling material 64 is increased, and the water stop performance can be improved.

  In the first embodiment and the second embodiment described above, the upper frame 11 and the like are extruded shapes made of a metal material such as aluminum. However, in the present invention, the first shape material such as the upper frame is a resin. It may be an extruded shape made of a material or a composite material of a metal and a resin.
