Description

  The present invention relates to a wall penetrating member attached to a through hole provided in a wall.

  Conventionally, when, for example, outdoor wiring such as equipment installed outdoors is drawn indoors, it is necessary to insert the wiring into a wall that divides outdoor and indoor. Since it is necessary to prevent the infiltration of water from the penetration portion, the penetration portion is provided with a wall penetration member.

  As such a wall portion penetrating member, for example, there is a method of securing fixation and water repellency by a sealing agent such as a silicone sealant in a state where the bush is disposed in the through hole using a resin bush.

  Moreover, the wall part penetration member which can be easily fixed by the operation | work from one side of a wall part is proposed, without using a sealing agent (patent document 1, 2).

JP, 2013-057406, A JP, 2014-101987, A

  However, in the case of a wet-type wall-penetrating structure using a sealing agent, depending on the skill of the operator, the dispersion such as waterproofness is large, and it is difficult to secure sufficient waterproofness. Moreover, since drying of a sealing agent requires time for 24 hours or more, there exists a problem that installation requires time.

  On the other hand, dry methods such as Patent Document 1 and Patent Document 2 can be performed from one side of the wall, and since no sealing agent is used, the workability is good. In these methods, since the wall portion penetrating member is fixed by sandwiching the wall portion, it is easy to secure the adhesion between the wall surface and the wall portion penetrating member. However, on the outer surface side of the wall portion, a part of the wall portion penetrating member protrudes by the thickness of the flange portion. The presence of such a protrusion on the wall surface hinders the installation of equipment installed on the outer surface of the wall such as an electrical installation or a socket on the outer surface of the wall. However, it is not easy to perform spot facing on the outer surface of the wall portion by the thickness of the flange portion.

  The present invention has been made in view of such problems, and is easy to install, and does not buffer the equipment installed on the outer surface of the wall and secures the adhesion between the wall penetrating member and the inner surface of the through hole. It is an object of the present invention to provide a wall penetration member etc. which can be done.

  In order to achieve the above-mentioned object, according to a first aspect of the present invention, there is provided a main body having a ring member, an external thread portion screwing with the ring member, and a flange portion disposed radially outward of the external thread portion. A sleeve, a first water blocking member disposed rearward of the flange portion of the main body sleeve, and a fixing member disposed rearward of the first water blocking member, relative to the ring member When the main body sleeve is rotated, the first water blocking member and the fixing member are sandwiched between the ring member and the flange portion of the main body sleeve, and the first water blocking member is The wall penetrating member is characterized in that the diameter can be increased by deforming along the fixing member.

  The outer surface of the fixing member has a tapered shape in which the outer diameter gradually increases from the front to the rear, the first water blocking member is a foam, and the fixing member is the first stop. The rubber member may be harder than the water member.

  The outer surface of the fixing member has a tapered shape in which the outer diameter gradually increases from the front to the rear, the first water blocking member is a foam, and the fixing member is the first stop. It may be a hard resin having a hardness higher than that of the water member, and a plurality of slits may be provided in the circumferential direction on the outer peripheral portion of the fixing member.

  The fixing member is divided into a front taper member and a flange member provided behind the taper member, and the taper member has a tapered shape in which the outer diameter gradually increases from the front toward the rear. The first water blocking member may be a foam, the tapered member may be harder than the first water blocking member, and the flange member may be an elastic member.

  The foam preferably has a tensile strength of 390 kPa or more.

  In this case, the foam is preferably a water-expandable urethane foam.

  A groove may be formed on the front surface of the ring member, and a second water blocking member may be disposed in the groove. In this case, the second water blocking member is preferably a water-expandable nonwoven fabric.

  A double-sided tape may be disposed on the front of the ring member.

  According to the first aspect of the invention, the relative movement of the ring member and the main body sleeve can push the first water blocking member along the fixing member. Therefore, the first water blocking member can be in close contact with the inner surface of the through hole. As a result, it is possible to prevent water from infiltrating from the gap between the through hole and the first water blocking member. Moreover, in order to ensure water repellency in the inner surface of a through-hole, it is not necessary to make the flange part of a wall part penetration member project on the outer surface of a wall part. Therefore, when installing an installation etc. in the outer surface of a wall, it does not buffer with a wall penetration member.

  Further, by forming a groove on the front surface of the ring member and arranging the second water blocking member, it is possible to secure higher water repellency. In particular, the edge on the indoor side of the through hole may have large unevenness due to chipping or the like, and it may be difficult to stop water, but if the second water blocking member is a water-expandable nonwoven fabric, such unevenness It is also possible to ensure water-proofing.

  Further, by arranging the double-sided tape on the front surface of the ring member, it is possible to perform temporary fixing when the wall-penetrating member is attached from the inner surface side of the wall.

  In addition, if the first water blocking member is a foam, it can be easily deformed, so that the first water blocking member can be pushed and spread with a small resistance. At this time, if the fixing member is a rubber member having a hardness higher than that of the first water blocking member, deformation of the fixing member is suppressed, and the first water blocking member is efficiently along the tapered shape of the fixing member. Can be expanded.

  In addition, if the fixing member is a hard resin having a hardness higher than that of the first water blocking member, sliding between the fixing member and the first water blocking member is good, and the first water blocking member is spread by small resistance. Can. Also, in this case, by providing a plurality of slits in the circumferential direction on the outer peripheral portion of the fixing member, the tip of the fixing member can be easily deformed and inserted into the through hole.

  In addition, when the fixing member is divided into the taper member and the flange member provided behind the taper member, when the flange member is deformed in contact with the inner surface of the through hole, the taper member is It is possible to suppress deformation such that the tip is opened.

  Further, by setting the tensile strength of the foam constituting the first water blocking member to 390 kPa or more, when inserting the tip of the fixing member into the inner surface of the first water blocking member, the first water stopping is more reliably performed. The diameter of the water member can be expanded. For example, if the tensile strength of the first water blocking member is weak and it is too soft, the first water blocking member is crushed in the front-rear direction, and the diameter can not be sufficiently enlarged.

  According to a second aspect of the present invention, the wall portion penetrating member according to the first aspect is a fixing structure of a wall portion penetrating member fixed to the through hole of the wall portion, wherein the outer diameter of the flange portion is The outer diameter of the fixing member is smaller than the inner diameter, the outer diameter of the fixing member is larger than the inner diameter of the through hole, and the outer diameter of the ring member is larger than the through hole. The end on the part side is inserted, the fixing member is deformed and inserted into the through hole, and the first water blocking member and the fixing member are formed by the ring member and the flange portion of the main body sleeve. Is pinched, the first water blocking member is deformed along the fixing member to expand in diameter, and is pressed against the inner surface of the through hole, and the outer surface side of the wall portion is a flange of the main body sleeve The fixing structure of the wall penetrating member characterized in that the portion does not protrude A.

  According to the second aspect of the present invention, it is possible to obtain a fixing structure of the wall-penetrating member which is excellent in water blocking property and excellent in construction workability. Under the present circumstances, since the flange part of a wall penetration member does not protrude on the outer surface of a wall, when installing an installation etc. on the outer surface of a wall, it does not buffer with a wall penetration member.

  A third invention is a method of fixing a wall penetrating member to a through hole of a wall using the wall penetrating member according to the first invention, wherein the outer diameter of the flange is the same as that of the through hole. The outer diameter of the fixing member is smaller than the inner diameter, the outer diameter of the fixing member is larger than the inner diameter of the through hole, and the outer diameter of the ring member is larger than the through hole. While inserting the end portion side and inserting the fixing member into the through hole while deforming the fixing member, the flange portion of the main body sleeve does not protrude from the outer surface side of the wall portion with respect to the ring member The main body sleeve is rotated, and the first water blocking member and the fixing member are sandwiched between the ring member and the flange portion of the main body sleeve, and the first water blocking member is arranged along the fixing member. To deform and expand the diameter, A method of fixing the wall portions penetrating member, characterized in that to press the inner surface of serial through-hole.

  According to the third invention, the construction work can be performed only from one side of the wall portion. In addition, since the first water blocking member can be expanded in diameter and pressed against the inner surface of the through hole only by rotating the main body sleeve, the water blocking property can be secured, so that the construction workability is good. Furthermore, according to the present invention, the wall penetrating member is fixed to the wall without causing part of the wall penetrating member to protrude to the outer surface side of the wall because the wall is not sandwiched and fixed from both sides of the wall. can do.

  According to the present invention, it does not stick out to the outer surface of the wall, is easy to install, and does not buffer the equipment installed on the outer surface of the wall, and secures the adhesion between the wall penetrating member and the inner surface of the through hole. It is possible to provide a wall penetration member etc. which can be done.

(A), (b) is a figure which shows operation | movement of the ring member 5 and the main body sleeve 3. FIG. (A), (b) is a figure which shows the process of attaching to the wall part 19 of the wall part penetration member 1. FIG. (A), (b) is a figure which shows the process of attaching the wall part penetration member 1 to the wall part 19. FIG. The perspective view of wall penetration member 1a. The top view of wall penetration member 1a. The perspective view of wall penetration member 1b. The top view of wall penetration member 1b. The FF sectional view taken on the line of FIG. The rear view of wall penetration member 1b.

  Hereinafter, the wall penetration member according to the present invention will be described. FIG. 1 is a perspective view showing a wall penetration member 1, FIG. 2 is a plan view showing the wall penetration member 1, and FIG. 3 is a cross-sectional view taken along the line AA of FIG.

  The wall portion penetrating member 1 mainly includes the main body sleeve 3, the ring member 5, the fixing member 9, the water blocking members 15a and 15b, and the like. An external thread 17 is formed in a predetermined range on the outer peripheral surface of the main body sleeve 3. The male screw portion 17 is screwed with a female screw portion formed on the inner peripheral surface of the ring member 5. The flange portion 11 is formed on the tip end side (the left side in FIGS. 2 and 3) of the male screw portion 17. The flange portion 11 protrudes radially outward of the main sleeve 3 substantially perpendicularly to the axial direction of the main sleeve 3 over the entire circumference. The flange portion 11 is formed at a position slightly behind the tip end of the main body sleeve 3. That is, the convex part 4 whose outer diameter is smaller than the flange part 11 protrudes on the tip side of the flange part 11.

  A water blocking member 15b, which is a first water blocking member, is disposed behind the flange portion 11 of the main body sleeve 3 (on the right side in FIGS. 2 and 3). The water blocking member 15 b is substantially cylindrical, and the inner surface of the water blocking member 15 b is in close contact with the outer circumferential surface of the main body sleeve 3. The water blocking member 15b is preferably an elastic body or a water-expandable member, more preferably a foam, and for example, a water-expandable urethane foam.

  The fixing member 9 is disposed behind the water blocking member 15b. The main body sleeve 3 penetrates the fixing member 9. The outer surface of the fixing member 9 has a tapered shape in which the outer diameter gradually increases from the front to the rear. That is, the outer diameter of the fixing member 9 on the water blocking member 15b side is small, and the outer diameter increases toward the rear. The maximum outer diameter portion of the fixing member 9 is larger than the outer diameter of the water blocking member 15 b and the outer diameter of the flange portion 11. The fixing member 9 is, for example, a rubber member having a hardness greater than that of the water blocking member 15b, and is elastically deformable.

  The sliding member 13 is disposed between the water blocking member 15 b and the fixing member 9. In the illustrated example, the sliding member 13 is disposed behind the water blocking member 15b. The sliding member 13 is made of, for example, a sheet made of a resin such as polyethylene, which has been subjected to a release treatment using a silicone coating or the like, release-treated polypropylene, release-treated polyethylene terephthalate, or fluorine resin. It is for improving the slippage between the water blocking member 15b and the fixing member 9 at the time of deformation.

  At the rear of the fixing member 9 of the main body sleeve 3, the male screw portion 17 and the ring member 5 are screwed together. The ring member 5 is formed in a flange shape projecting outward in the radial direction from a screwing portion with the male screw portion 17. The ring member 5 is, for example, circular. The outer diameter of the ring member 5 is larger than the maximum outer diameter portion of the fixing member 9.

  A groove is formed in the circumferential direction on the front surface (the fixing member 9 side) of the ring member 5. A water blocking member 15a, which is a second water blocking member, is disposed in the groove. The water blocking member 15a is preferably an elastic body or a water expansible member, and is, for example, a water expansible nonwoven fabric. Moreover, the double-sided tape 7 is stuck over the circumferential direction on the outer peripheral side of the groove.

  The sliding member 13, the water blocking member 15a and the double-sided tape 7 are not necessarily essential. It may be arranged appropriately according to the required specification and structure. The ring member 5 may be rectangular. Moreover, when arranging the double-sided tape 7 with respect to the ring member 5, the double-sided tape 7 may be arrange | positioned in rectangular other than circular.

  Next, the operation of the ring member 5 and the main body sleeve 3 will be described. When the main body sleeve 3 is rotated with respect to the ring member 5 from the state shown in FIG. 4A, the ring member 5 can be moved relative to the main body sleeve 3. The rear end portion of the main body sleeve 3 is formed, for example, in a hexagonal cross section, and has a flat portion on the outer peripheral surface. The flat portion is a gripping portion that is gripped by a tool. Therefore, the main body sleeve 3 can be easily rotated by a tool or the like.

  When the main body sleeve 3 is rotated relative to the ring member 5 and the main body sleeve 3 is moved back in the backward direction, the ring member 5 is moved forward relative to the main body sleeve 3 (see FIG. Middle arrow B). When the ring member 5 moves to the front of the main body sleeve 3, the front fixing member 9 is pressed by the ring member 5.

  As shown in FIG. 4B, when the main sleeve 3 is further rotated with respect to the ring member 5, the fixing member 9 moves forward together with the ring member 5, and further presses the water blocking member 15b on the front side. That is, the water blocking member 15 b and the fixing member 9 are sandwiched between the ring member 5 and the flange portion 11 of the main body sleeve 3.

  At this time, as described above, the fixing member 9 has high hardness with respect to the water blocking member 15b. For this reason, the water blocking member 15b is largely deformed in a preferential manner. At this time, since the front surface of the fixing member 9 has a tapered shape, the water blocking member 15b can be deformed along the tapered shape of the front surface of the fixing member 9 to be expanded in diameter. As described above, by moving the ring member 5 forward relative to the main sleeve 3 by a predetermined amount, the maximum outer diameter of the water blocking member 15 b is enlarged larger than the maximum outer diameter of the fixing member 9. be able to.

  When the diameter of the water blocking member 15b is expanded along the fixing member 9 while being deformed, if the friction between the water blocking member 15b and the fixing member 9 is large, the rotational resistance of the main sleeve 3 is increased. In particular, when the fixing member 9 is made of rubber, the frictional resistance with the water blocking member 15b is large. On the other hand, in the present embodiment, the sliding member 13 is disposed between the water blocking member 15 b and the fixing member 9 in order to reduce this friction. The sliding member 13 is deformed together with the water blocking member 15 b, and is disposed between the water blocking member 15 b and the fixing member 9 so as to facilitate the sliding of the both, and the rotational resistance of the main sleeve 3 can be reduced.

  Next, a method of fixing the wall through member 1 to the through hole of the wall using the wall through member 1 will be described. First, as shown to Fig.5 (a), the through-hole 21 of a predetermined | prescribed size is formed in the wall part 19. As shown in FIG. At this time, the outer diameter of the flange portion 11 is smaller than the inner diameter of the through hole 21, the outer diameter of the fixing member 9 is larger than the inner diameter of the through hole 21, and the outer diameter of the ring member 5 is larger than the through hole 21. The size of the through hole 21 is determined so as to be larger.

  From this state, the end of the main body sleeve 3 on the flange 11 side is inserted from the indoor side (right side in the figure) of the wall 19 (in the direction of the arrow C in the figure). As shown in FIG. 5B, in the state where the fixing member 9 is positioned inside the through hole 21, the vicinity of the tip of the fixing member 9 is deformed, and the wall through member 1 is inserted into the through hole 21. . At this time, since the fixing member 9 has a tapered shape, it has a function as a guide with respect to the through hole 21, and the central axis of the wall through member 1 substantially matches the central axis of the through hole 21.

  When the fixing member 9 is deformed and inserted into the through hole 21, since the outer diameter of the fixing member 9 is larger than the inner diameter of the through hole 21, the tip of the fixing member 9 is pressed against the inner surface of the through hole 21. Become. Therefore, at the time of insertion, it can be easily inserted into the through hole 21 by the tapered shape of the fixing member 9, but when the wall portion penetrating member 1 is pulled back (inside), the fixing member 9 is a through hole It is caught on the inner surface of 21 and pulling-out of wall penetration member 1 is prevented. That is, the fixing member 9 has a role of fixing the wall portion penetrating member 1 to the through hole 21.

  When the wall portion penetrating member 1 is completely pushed into the through hole 21, the front surface of the ring member 5 contacts the indoor surface of the outer circumferential wall portion 19 of the through hole 21 via the double-sided adhesive tape 7. Therefore, the ring member 5 can be temporarily fixed to the wall portion 19 by the double-sided tape 7. At this time, at least a part of the water blocking member 15 a contacts the indoor surface of the outer circumferential wall 19 of the through hole 21. Moreover, in this state, a part of the flange portion 11 of the main body sleeve 3 may protrude to the outdoor side (left side in the drawing) of the wall portion 19.

  From this state, as shown in FIG. 6A, when the main sleeve 3 is rotated with respect to the ring member 5 (arrow D in the figure), the main sleeve 3 is rotated relative to the ring member 5 as described above. It can be moved backward (arrow E in the figure). That is, the ring member 5 moves forward relative to the main body sleeve 3.

  As shown in FIG. 6B, when the main sleeve 3 is rotated relative to the ring member 5 so that the flange portion 11 of the main sleeve 3 does not protrude from the outer surface side of the wall 19, as described above, The water blocking member 15 b and the fixing member 9 can be sandwiched between the ring member 5 and the flange portion 11 of the main body sleeve 3. At this time, the water blocking member 15 b can be deformed along the fixing member 9 to be expanded in diameter, and can be pressed against the inner surface of the through hole 21. Therefore, the water blocking member 15 b is pressed against the inner surface of the through hole 21, and water blocking can be secured.

  By the above, the wall penetration member 1 is fixed to the wall 19, and the fixing structure to the wall 19 of the wall penetration member 1 can be obtained. Thereafter, the installation is completed by inserting a wire or the like into the wall portion penetrating member 1.

  In addition, as for the tensile strength of the foam which comprises the water stop member 15b, it is desirable that it is 390 kPa or more. If the water blocking member 15b is too soft, the fixing member 9 is moved, and when the water blocking member 15b is sandwiched between the fixing member 9 and the flange portion 11, the water blocking member 15b is crushed in the front-rear direction. The diameter of the member 15b can not be sufficiently increased.

  Actually, when the same test is performed with foams having different tensile strengths, the water blocking member 15b having a tensile strength of 390 kPa could be sufficiently expanded in diameter, but with the water blocking member 15b having a tensile strength of 270 kPa The crushing in the front-rear direction was large, and the diameter expansion amount could not be obtained sufficiently. If the amount of diameter expansion is small, the pressing force on the inner surface of the through hole 21 can not be sufficiently obtained, and the water barrier property may be reduced. The tensile strength of the foam can be measured at a tensile speed of 200 mm / min and a thickness of 15 mm according to JIS K6400-5.

  As described above, according to the present embodiment, when attaching the wall penetrating member 1 to the wall 19, the wall of the wall 19 is rotated by rotating the main sleeve 3 from the indoor side of the wall 19. The penetrating member 1 is fixed. For this reason, it is not necessary to work with the front surface and the rear surface of the wall 19, and the mounting is easy.

  In addition, after the wall portion penetrating member 1 is attached to the wall portion 19, the flange portion 11 of the main body sleeve 3 does not protrude on the outer surface side of the wall portion 19. For this reason, equipment installed on the outer surface of the wall 19 and the main body sleeve 3 do not buffer each other. When the wall portion penetrating member 1 is attached to the wall portion 19, the convex portion 4 may protrude to the outer surface of the wall portion 19 as long as the flange portion 11 does not protrude from the outer surface of the wall portion 19. The convex portion 4 has a small diameter and hardly interferes with the installation of other equipment etc. Further, by making the convex portion 4 project, rain water etc. which is attached to the outer surface of the wall portion 19 is inside the main body sleeve 3 The effect of suppressing entering can also be obtained.

  Moreover, since the water blocking member 15 b is pressed against the inner surface of the through hole 21, the water blocking can be reliably ensured. In particular, when a water-expandable urethane foam is used as the water blocking member 15b, in addition to the effect of pressing the water blocking member 15b against the inner surface of the through hole 21 to stop the water, Yes, it is possible to secure water tightness more firmly. Furthermore, by disposing the water blocking member 15 a on the front surface of the ring member 5, it is possible to suppress water from entering the room even if water enters the gap between the water blocking member 15 b and the through hole 21. it can. In particular, the edge on the indoor side of the through hole 21 is chipped, and the foam can not follow and water blocking may be difficult in some cases, but if the water blocking member 15b is a water-expandable nonwoven fabric, such irregularities On the other hand, it is possible to ensure the waterproofness.

  In addition, by using the double-sided tape 7, the ring member 5 can be easily temporarily fixed to the wall portion 19. For this reason, it is possible to suppress that the ring member 5 is separated from the wall portion 19 or that an axial deviation of the main body sleeve 3 or the like occurs when the main body sleeve 3 is subsequently rotated.

  Further, since the tensile strength of the water blocking member 15b is sufficiently high, it is difficult for the fixing member 9 to be crushed in the front-rear direction, and the diameter of the water blocking member 15b can be expanded more reliably.

  Next, a second embodiment will be described. FIG. 7 is a perspective view showing the wall penetrating member 1a, and FIG. 8 is a plan view showing the wall penetrating member 1a. In the following description, about the composition which plays the same function as wall penetration member 1, the same numerals as Drawing 1-Drawing 6 are attached, and overlapping explanation is omitted.

  The wall penetrating member 1a has substantially the same structure as the wall penetrating member 1 except that the fixing member 9a is used. The fixing member 9a has substantially the same shape as the fixing member 9, but a plurality of slits 23 are provided in the circumferential direction on the outer peripheral portion of the fixing member 9a. Each slit 23 is formed toward the outer peripheral portion of the fixing member 9a. That is, the distal end of the fixing member 9 a in the radial direction is divided into a plurality of pieces in the circumferential direction.

  The fixing member 9a is made of a hard resin having a hardness higher than that of the water blocking member 15b. Therefore, as compared with the rubber fixing member 9, sliding with the water blocking member 15b is good. For this reason, in the present embodiment, the sliding member 13 is unnecessary.

  The wall penetrating member 1 a can be fixed to the wall 19 in the same manner as the wall penetrating member 1. When the wall through member 1 a is inserted into the through hole 21, the tip of the fixing member 9 a is pressed against the inner surface of the through hole 21 to be deformed. Here, the fixing member 9a made of hard resin has a smaller amount of compressive deformation compared to the fixing member 9 made of rubber, but since the tip of the fixing member 9a is divided into a plurality by the slit 23, each portion Thus, the fixing member 9a can be inserted into the through hole 21 by elastic deformation.

  According to the second embodiment, the same effect as that of the first embodiment can be obtained. Moreover, since the slip between the fixing member 9a and the water blocking member 15b is good, the rotational resistance of the main body sleeve 3 can be reduced.

  Next, a third embodiment will be described. FIG. 9 is a perspective view showing the wall penetrating member 1b, FIG. 10 is a plan view showing the wall penetrating member 1b, and FIG. 11 is a cross-sectional view taken along the line F-F in FIG. The wall penetrating member 1b has substantially the same structure as the wall penetrating member 1, but differs mainly in that the fixing member 9b is used.

  The fixing member 9b is divided into a flange member 8a and a taper member 8b. That is, the fixing member 9b is not integral but is configured by combining two members. A taper member 8b is disposed in front of the fixing member 9b. A flange member 8a is disposed behind the taper member 8b.

  The taper member 8 b has a tapered shape in which the outer diameter gradually increases from the front to the rear. The taper member 8 b is made of, for example, a resin, and has a hardness higher than that of the water blocking member 15 b. For example, the taper member 8b is made of resin, can slide well with respect to the water blocking member 15b, and can apply a hard resin with small deformation.

  On the other hand, the flange member 8a is made of an elastic member such as rubber and can be easily deformed. The flange member 8 a has an outer diameter larger than the inner diameter of the through hole 21. Therefore, when inserted into the through hole 21, the vicinity of the outer edge of the flange member 8 a is deformed, and the flange member 8 a (fixing member 9 b) is fixed to the through hole 21 by the repulsive force.

  At this time, since the fixing member 9b is divided into the flange member 8a and the taper member 8b, stress applied to the flange member 8a is not transmitted to the taper member 8b even if the flange member 8a is deformed. For this reason, with the deformation of the flange member 8a, the tip end of the taper member 8b does not open, and the tip end of the taper member 8b is inserted inside the water blocking member 15b more reliably, and the diameter of the water blocking member 15b is enlarged. can do.

  In the wall portion penetrating member 1b, a flat portion is not provided on the outer peripheral surface at the rear of the main body sleeve 3, and a fine uneven shape is formed in the circumferential direction. Since such unevenness has an anti-slip effect, the operator can easily rotate the main body sleeve 3 by hand.

  Moreover, FIG. 12 is a rear view of wall penetration member 1b. In the present embodiment, a mark 25 is formed on the back of the ring member 5 to indicate the direction in which the main body sleeve 3 is rotated at the time of attachment. After the wall portion penetrating member 1 b is inserted into the through hole 21, the main body sleeve 3 is rotated in the direction of the arrow indicated by the mark 25 to securely fix the wall portion penetrating member 1 b to the through hole 21. Water quality can be secured.

  According to the third embodiment, the same effect as that of the first embodiment can be obtained. Further, since the fixing member 9b is divided into the flange member 8a and the taper member 8b, even if the flange member 8a is deformed, the taper member 8b is not affected by this, and the taper end of the taper member 8b is I can not open it. Therefore, the diameter of the water blocking member 15b can be reliably increased along the tapered shape of the tapered member 8b.
