According to the present invention, in an attached protective cover to which the engaged portion of the base and the engaging portion of the lid are assembled, by ensuring a large amount of bending deformation of each side wall of the lid, A tool insertion space into which a tool can be inserted is formed between the side wall of the attached protective cover and the side wall of another linear portion protective cover connected to the attached protective cover, thereby facilitating the release of the engagement. The challenge is to make it possible to do

A first aspect of the invention for solving the above-mentioned problems comprises a flat plate-like base and a lid body having a ceiling wall and a pair of side walls arranged opposite to each other, which are assembled to each other and have wiring and piping inside. An attached protective cover in which a material installation path is formed, and another straight part protection cover is inserted and connected to a connection port formed at one end of the installation path,
An engaging portion that is assembled by engaging with the engaged portion of the base is provided inside the pair of side walls of the lid, and the engagement is released by separating the pair of side walls from each other. is,
In the assembled state of the base and the cover, a contact is provided on the inner side of the engaged portion of the base along the connection direction of the connection port and on the inner side of the side wall of the cover on the outside. A bending deformation permissible space is formed that allows the side wall to bend and deform inward due to pressure from the
In a state where the side wall is pressed from the outside, the front side along the connection direction of the connection port from the pressed portion of the side wall that is flexurally deformed inward contacts the fulcrum portion of the base, thereby causing the flexural deformation. It is characterized in that the edge portion of the portion of the connecting port of the side wall that is formed is flexurally deformed outward.

According to the invention of claim 1, in a state in which another protective cover is connected to the connecting port of the attached protective cover, in the state in which the base and the lid are assembled, along the connecting direction of the connecting port, the A bending deformation permissible space is formed on the inner side of the side wall of the lid body behind the engaged portion of the base to allow the side wall to be bent and deformed inward by pressure from the outside. Therefore, when the opening ends (end edges) of the opposite side walls of the lid body that are apart from the top wall are pressed inward to cause the side walls to bend inward, the side walls will bend inward. The front side of the deformed side wall along the connection direction of the connection port contacts the fulcrum portion of the base, so that the edge of the connection port portion of the flexurally deformed side wall is pushed outward. and a tool insertion space into which a tool can be inserted is formed between the protective cover and the outer surface of the separate protective cover.

When the tool inserted from the tool insertion space is pried outward while being in contact with the outer surface of the engaged portion of the base, the portion of the side wall of the lid extending from the fulcrum portion to the connection port is bent. , the engaging portion of the lid is further deformed outward to move the engaging portion of the lid outward, thereby separating the engaging portion of the lid from the engaged portion of the base. , By slightly lifting the lid upward with respect to the base, two engaging structure portions (the engaged portion of the base and the engagement of the lid) facing each other along the width direction orthogonal to the connection direction refers to the structure itself that engages each other) to release said engagement.

Thus, according to the first aspect of the invention, by providing the flexural deformation allowance space for excessively deforming the side wall of the lid of the attached protective cover, the excessive deformation of the side wall causes the connection opening of the side wall to be deformed. Only by inserting a tool into the tool insertion space formed between the side wall of the separate straight part protective cover and prying it, the engagement between the base of the attached protective cover and the lid body can be released. Easy to do. Moreover, since the space for allowing bending deformation can be secured by, for example, removing a portion of the base that interferes with the large bending deformation of the side wall of the lid, a tool insertion groove is provided near the engaged portion of the base. The structure is much simpler than the structure provided with , and the missing part of the base is covered with the lid and is not visible from the outside, so that the aesthetic appearance can be maintained. In addition, due to the flexural deformation of the side wall of the lid, the side wall of the lid of the connection port portion of the attached protective cover and the side wall of the lid of another protective cover connected to the attached protective cover will not be attached. Since the tool insertion space is formed by the bending deformation of the side wall of the cover of the protective cover, the tool can be inserted without damaging the outer wall of another straight part protective cover, and the side wall of the other protective cover is damaged. not.

According to the invention of claim 2, when the installation path of the attached protective cover is bent, each bending deformation is performed at the portion inside the bend, and when it is branched, at the branched portion. Since the permissible spaces communicate with each other, it is possible to increase the amount of flexural deformation when each side wall of the lid body is flexurally deformed inward, thereby increasing the opening of the tool insertion space.

The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, the bending deformation permissible space is formed between the side edge of the base and the inner surface of the side wall of the lid. there is

According to a third aspect of the invention, each side wall of the lid body is arranged outside each edge of the base, and the end face of the side wall on the opening side farthest from the top wall is in contact with the wall surface, A bending deformation permissible space is formed between the side edge of the base and the inner surface of the side wall of the lid. For this reason, the flexural deformation permissible space can be formed by, for example, partially removing the specific portion of the base so that the side edge of the specific portion of the base is separated from the inner surface of the side wall.

The invention of claim 4 is based on the invention of claim 1 or 2, wherein the base has a polymerized wall that overlaps with the side wall of the lid along the inner and outer directions when assembled with the lid. The overlapping wall is cut off at a portion facing the pressing portion of the side wall on the base to form the bending deformation permissible space, and the overlapping wall on the base The edge of the side wall of the lid is in contact with the portion where the is missing.

According to the invention of claim 4, since the entire inside portion of the missing overlapping wall in the base becomes a wide bending deformation permissible space, there is an advantage that the side wall can be deformed inward to the maximum.

According to the invention of claim 5, in the invention of claim 4, the base has a flange portion that protrudes outward from the outer surfaces of the pair of side walls of the lid body, and the side walls of the lid body are opposed to the ceiling wall. A part of the side edge is arranged on the flange portion, and by pressing the side wall on the flange portion inward, the side wall that is flexurally deformed inward is pushed forward along the connection direction of the connection port.

The engaged portion is characterized in that it has a structure that allows the engaging portion engaged with the engaged portion to slide to the rear side of the connection port in the connection direction.

When the side wall of the lid is bent inward, the engaging portion of the lid may move along the connection direction of the connection port with respect to the engaged portion of the base. According to the present invention, the side wall of the lid body is flexurally deformed inward without hindrance because of the structure that allows the movement. In addition, by permitting the movement, the amount of outward deflection of the edge of the connection port can be increased.

The invention according to claim 7 is the invention according to any one of claims 1 to 6, wherein the wall thickness of the pressed portion of the side wall is such that bending deformation due to pressing at the pressed portion is It is characterized in that it is formed so thick that it can reach the edge on the front side as it is.

In each invention of claims 1 to 6, the bending deformation inward due to the pressing of the side wall causes the side wall on the front side along the connection direction to be bent outward by the fulcrum portion of the base. By specifying the thickness of the side wall as in the seventh aspect of the invention, the flexural deformation of the pressed portion of the side wall extends directly to the end edge on the front side along the connection direction of the side wall. become. As a result, a tool insertion opening having a size necessary for inserting a tool can be formed in the connecting port portion of the side wall with a minimum amount of inward bending deformation of the side wall of the lid.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail with reference to several best examples. Here, the accessory protective cover according to the present invention, together with the straight part protective cover for protecting the straight part of the wiring/piping material, is once assembled with the wiring/piping material accommodated inside, and then, for some reason, , when it becomes necessary to release the engagement between the engaged portion of the base and the engaging portion of the lid constituting the attached protective cover, the structure is characterized in that the engagement can be easily released. Therefore, in the explanation of the bases V ₁ to V ₅ and the lids L ₁ to L ₅ in the following embodiments, only the parts related to the above matters will be explained in detail, and the unrelated parts will be briefly explained. Explain or omit the explanation.

The attached protective cover of Example 1 is a bending protective cover C ₁ used to connect two straight part protective covers C ₁₁ by bending (bending) 90° on the wall surface W ₁ , and the wall surface W ₁ , and a _lid body _L1 integrally attached to the base _V1 by an engaging structure. Both the base V ₁ and the lid L ₁ are L-shaped in plan view, and are formed by resin injection molding. The L-shaped base _V1 is both ends of the L-shaped base 1 along the arrangement direction _Q1 of the piping material P, and both ends in the width direction and the outer corners are measured. Standing walls 2 are partially erected at five locations, respectively, and as a result, the standing wall missing portions 8 are formed between adjacent standing walls 2 . Engaged portions E ₁₁ each having a concave shape are formed at the lower ends of the outer sides of the respective vertical walls 2 , and the upper half portions of the outer sides of the respective vertical walls 2 are engaged with the lids L ₁ , which will be described later. A sliding inclined surface 2a is formed for slightly bending and deforming the side wall 12 outward while sliding the joining portion _E12 . In FIG. 4-A, the protruding width from the side end face 1a of the base portion 1 of the standing wall protruding portion 2b protruding from the side end face 1a (see FIG. 5) of the base portion 1 in the standing wall 2 is "D".

Of the five standing walls 2 in total, the length of the two standing walls 2 located outside along the bending direction and at both ends along the arrangement direction _Q1 is the same as that of the remaining three standing walls 2. It is formed longer than it is long. Each engaged portion E ₁₁ is a portion to be engaged with an engaging portion E ₁₂ described later of the lid L _{1 .} It is conceivable that the engaging portion _E12 of the lid body _L1 moves in the arrangement direction _Q1 with respect _to the engaged portion E11 of 1, so that the movement of _the engaging portion _E12 is not hindered. The engaged portion _E11 of the base _V1 has the same cross-sectional shape over its entire length, and the engaging portion _E12 has a structure in which it can slide freely with respect to the engaged portion _E11 . It has become.

Both end portions of the base portion 1 along the arrangement direction _Q1 are formed thicker than other portions in order to increase the strength of the engaged portion _E11 formed in the portion. . Screw insertion holes 3 are formed at a total of three locations, ie, both end portions and the central portion along the arrangement direction Q ₁ in the central portion in the width direction of the base portion 1 . In the part of the base 1 that connects the screw insertion holes 3 in a straight line, the piping material P bent inside the bending protection cover _C1 is arranged in the center of the width direction of the base _V1. An arrangement confirmation line 4 for confirmation is formed. 1 to 3, 5 protrudes from both ends of the base 1 in the arrangement direction Q ₁ along the arrangement direction Q ₁ to protect the straight portion of the bending protection cover C ₁ from the base V ₁ . A pair of positioning pieces for positioning the base _V11 of the cover _C11 in the width direction.

1, 2 and 5, particularly in FIG. 5, the outer side of the bending of the base portion 1 of the base V ₁ is shown in longitudinal section in relation to each side wall 12 of the lid L ₁ . , rectangular cutouts 6 are formed along the arrangement direction _Q1 near the vertical walls 2 provided at both ends in the arrangement direction _Q1 , and the inner side of the base 1 In the corner portion, each notch 6 connected along the arrangement direction _Q1 is formed at a predetermined interval with each vertical wall 2 on the inner side of the bend. In this way, by forming the long rectangular notch 6 along the arrangement direction _Q1 , the portion of the base 1 where the notch 6 is formed has an outer edge (outer end surface) and an inner The edge (inner end surface) is retracted toward the center in the width direction of the base 1, so that the lid present in each notch 6 in a state where the base V ₁ and the lid body L ₁ are assembled. The amount of bending deformation inward of the side wall 12 of the body L ₁ can be increased.

As shown in FIGS. 4-A and 5, when _the base V ₁ and the lid L 1 are assembled, the inner and outer side end faces 1a of the base V ₁ and the side walls 12 of the lid L ₁ are separated from each other. An assembly gap 14 corresponding to the protrusion width D of the standing wall protrusion 2b is formed between the inner surface and the inner surface. Therefore, in the assembled state of the base _V1 and the lid _L1 , the spaces formed by the assembly gaps 14 and the notches 6 of the base 1 are flexed to the inside of the side wall 12 of the lid _L1 . A flexural deformation permissible space _K1 that allows deformation is formed. Of the four cutouts 6 formed in the base 1, the two cutouts 6 facing each other inside and outside the bend extend in a direction perpendicular to the arrangement direction _Q1 (the width direction of the base 1). Therefore, when the base V ₁ and the lid L ₁ are assembled, the opposing portions of the side walls 12 of the lid L ₁ are pinched between the fingertips and pressed strongly inward. Each side wall 12 is flexurally deformed inward by pressing the side walls 12 to the inside.

On the other hand, the lid _L1 has a shape in which an L-shaped flat plate-shaped top wall 11 and each side wall 12 vertically installed toward the base ₁ in an assembled state with the base V1 are continuously continuous. Inside the end edges of the side walls 12 facing each other at a predetermined interval on the side of the assembly opening 13, the outside of the engaged portions _E11 of the base _V1 in the curved direction is provided. A linear engaging portion _E12 engaged with each of the remaining four engaged portions _E11 , excluding only the engaged _portion E11 provided on the upright wall 2, protrudes into the internal space. formed by Both ends of the inner space of the lid body L ₁ along the arrangement direction Q ₁ are partially covered with the outer side of the lid body L ₁₁ of the linear part protective cover C ₁₁ , respectively, so that the protective cover C ₁₁ Connection openings _J1 to be connected are formed respectively. The "direction of connection" between the bend protection cover C ₁ and the straight part protection cover C ₁₁ is the same as the "arrangement direction Q ₁ (Q ₂ to Q ₅ )" of the piping material P.

Then, as shown in FIGS. 2 and 3, the base V ₁ of the bending protection cover C ₁ is fixed to the wall surface W ₁ using screws B, and both connection portions of the base V ₁ are connected to the straight portion protection After connecting the base V ₁₁ of the cover C ₁₁ and connecting each piping material P arranged on each base V ₁₁ with an elbow U on the base V ₁ , each base of the straight part protection cover C ₁₁ The base V ₁₁ is covered with the lid L ₁₁ . In this state, the bases _V11 of the two straight part protection covers _C11 are covered with the lid bodies _L11 , respectively, and then the bases of the bending protection covers _C1 fixed to the wall surface _W1 first. When the lid L ₁ is pressed against the table V ₁ , the opposing engaging portions E ₁₂ of the lid L ₁ engage the outer sliding inclined surfaces 2 a of the opposing vertical walls 2 of the base V ₁ . By sliding along, each side wall 12 of the lid L ₁ is slightly flexed outwardly and then restored to its original shape, so that each engaged portion E 11 of the base V 1 and each side wall ₁₂ of the base V ₁ are restored. The engaging portions E ₁₂ of the lid L ₁ are engaged with each other, and the base V ₁ and the lid L ₁ are assembled together. As a result, the two straight portion protection covers C ₁₁ are bent while the ends of the lids L ₁₁ of the straight portion protection covers C ₁₁ are covered from the outside by the lids L ₁ of the bending protection cover C ₁ . The piping material P connected through the protective cover C ₁ and bent 90° in the middle is housed and protected by the respective protective covers C ₁ and C ₁₁ .

4-A(a) and FIG. 5 show a cross-sectional view and a vertical cross-sectional view of the engaging structure E ₀ [see FIG. 4-A(a)] in this state. In this way, the base V ₁ and the lid L ₁ of the bending protection cover C ₁ are located at both ends in the arrangement direction Q 1 and along a direction substantially orthogonal to the arrangement direction _{Q 1 .} Since the two pairs of the engaging structure portions _E0 are firmly engaged with each other, it is not easy to release the engagement. In addition, in the bending protection cover _C1 of Example 1, the vertical wall 2 provided on the outer side of the corner portion of the base _V1 functions only as a fulcrum portion when the lid body _L1 is flexurally deformed. By providing an engaging portion _E12 corresponding to the engaged portion _E11 provided on the standing wall 2 outside the corner portion of the base _V1 of the lid _L1 , a total of five engaging structure portions are formed. It is also possible to provide

Then, when it becomes necessary to release the engagement between the base V ₁ of the bent protective cover C ₁ and the lid L ₁ for some reason, as shown in FIG. 4-A(b) and FIG. Then, the ends of the side walls 12 of the lid L ₁ on the side of the assembly opening 13, and the inner portions of the side walls 12 of the lid L 1 , which are flexural deformation permissible spaces K ₁ formed by the cutouts 6, are strongly pressed inward to apply a pressing force F is applied, the portion to which the respective pressing force F is applied is provided with a notch 6 in the base portion 1 of the base V ₁ on the inner side, and a flexural deformation allowable space K ₁ is formed, so that the outer In the side wall 12, the outer edge of the inner end of the engaged portion _E11 on the connection port _J1 side serves as the first fulcrum portion _R11 , and the engaged portion E11 of the outer corner portion of the base portion 1 has the first fulcrum portion _R11 . The outer edge portion on the first fulcrum portion R ₁₁ side becomes the second fulcrum portion R ₁₂ and both ends are supported by the first and second fulcrum portions R ₁₁ and R ₁₂ . , the outer edge of the inner end of the engaged portion E ₁₁ on the side of the connection port J ₁ serves as a fulcrum R ₁₁ ' and is supported by a cantilever. Beyond the side end surface 1a, the side wall 12 of the lid _L1 can be flexurally deformed inward. The flexural deformation of the pressed portion of each of the outer and inner side walls 12 is transmitted as it is to the end of each side wall 12 on the side of the connection port _J1 , thereby protecting the side walls 12 of the bending protection cover _C1 and the straight portion protection. Tool insertion spaces A ₁ and A ₁ ' are formed between the cover C ₁₁ and the side wall 101 of the lid L ₁₁ .

Here, as shown in FIG. 5, the straight portion protective cover _C11 is inserted into the connecting port _J1 of the lid _L1 of the bend protective cover _C1 , thereby forming the side wall 101 of the straight portion protective cover _C11 . Since the side wall 12 of the lid _L1 and the side wall 12 of the lid _L1 have a predetermined overlapping length M, the bending deformation of the pressed portion of the side wall 12 of the lid _L1 is greatly expanded at the connection port J1. Since the clearance between the side walls ₁₀₁ and 15 of the straight portion protection cover C11 and the curved protection cover _C1 , that is, the opening of the tool insertion space _A1 is formed large, the tool T can be easily inserted. Here, the pressed portions corresponding to the notches 6 of the base V ₁ at the ends of the side walls 12 of the lid L ₁ on the assembly opening 13 side have the same thickness as the other portions. Therefore, the bending deformation of the pressed portion of the side wall 12 is transmitted as it is to the end portion of the side wall 12 on the side of the connection port _J1 . The flexural deformation of the side wall 12 shown in FIG. 6 is deformation of the side wall 12 only within the assembly gap 14 generated by assembling the base _V1 and the lid _L1 , forming the tool insertion space _A1. Fig. 3 is an example of bending deformation of the side wall 12 which is applied. Further, since the side wall 101 of the straight portion protection cover C ₁₁ and the side wall 12 of the lid L ₁ have the overlapping length M, the side wall 12 of the lid L ₁ is bent outward by the tool T. When deforming, the tool T presses the side wall 101 of the straight portion protection cover C ₁₁ inward, and there is _a risk of damage. Since it is covered with the side wall 12 and does not appear in the external appearance, the appearance does not deteriorate.

In the above state, a tool T such as a slotted screwdriver is inserted into the tool insertion space _A1 between the outer side wall 12 and the side wall 101 of the straight section protection cover _C11 , and the tip of the tool T is inserted into the straight section protection cover. When the tool T is pried while being in contact with the outer surface of the side wall 101 of C ₁₁ , the side wall that is flexurally deformed by the insertion of the tool T as shown in FIGS. 4-B(c) and 7 . 12 is _flexurally deformed further outward to disengage the engaging structure _E0 , and as shown in _{FIG .} are separated.

In addition, the bending deformation of the side wall 12 of the lid _L1 described above is deformation of the side wall 12 only within the assembly gap 14 generated by assembling the base _V1 and the lid _L1 . When the pressure F is relatively higher than the above, it increases in proportion to the bending deformation amount of the side wall 12 . The bending deformation example of the side wall 12 shown in _{FIG .} Thus, the advantage of forming the notch 6 in the base 1 of the base V ₁ and forming the bending deformation permissible space K ₁ directly above it is that the pressing force F against the side wall 12 is large, and the side wall 12 is bent. It is possible to avoid interference with the base portion 1 and to be flexurally deformable when the amount of deformation becomes large.

In addition, as shown in FIG. 9, it is also possible to insert a tool T between the inner side wall 12 and the side wall ₁₀₁ of the straight portion protection cover C11 to release the engagement of the engaging structure portion _E0 . is.

Next, with reference to FIGS. 10 to 13, the branch protective cover _C2 , which is the accessory protective cover of the second embodiment of the present invention, will be described. The branch protection cover C ₂ is used to branch one pipe material P into two pipes on the wall surface W ₁ , or vice versa, to merge two pipe materials P into one pipe. By arranging a cheese joint (also called a T-shaped joint, a branch joint, or a three-way joint) N inside the cover _C2 , a total of three connection ports _J2 are formed, and the above branching or merging is performed. . In addition, in the bending protection cover _C1 of the first embodiment, the principle of disengagement of the engaging structure _E0 between the base _V1 and the lid _L1 using the flexural deformation of the side wall 12 of the lid _L1 will be detailed. , and the disengagement principle of the engaging structure E ₀ is the same in each of the protective covers C ₂ to C ₅ of the following Examples 2 to 5, including the present Example 2. Corresponding parts of the curved protective cover C ₁ of Example 1 are denoted by corresponding reference numerals, and _redundant parts are _omitted . Only the basic configuration of the cover that differs from the first embodiment and the portions that differ from the first embodiment in the bending deformation of the side wall of the lid will be described.

Since the branch protection cover C ₂ is used to branch one pipe material P into two pipes, or conversely, to merge two pipe materials P into one pipe, the bend protection cover C of the first embodiment ₁ is L-shaped in plan view, but _the basic shape is T _{- shaped} . Identical to the cover _C1 . That is, at both ends in the linear arrangement direction _Q2 of the linear connection portion where the two piping members P are linearly connected in the T-shaped base portion 21, the two pipe members P are opposed along the width direction. A short standing wall 22 having the same length is erected, and a long standing wall 22 is formed on the outer edge of the linear connection portion of the base V ₂ in the arrangement direction Q ₂ , and further, The straight connecting portions of the base portion 21 are perpendicular to each other, and at the branch portion of which the length is approximately half, a short standing wall 22 is provided at the end portion along the arrangement direction _Q2 to face in the width direction. is erected. As a result, a vertical wall missing portion 28 is formed between the adjacent vertical walls 22 in the peripheral portion of the base portion 21, and an assembly with the lid L ₂ is formed between the adjacent vertical wall missing portions 28 in the base portion 21. Rectangular cutouts 26 are respectively formed along the arrangement direction _Q2 for forming the flexural deformation permissible space _K2 of the side wall 32 right above it. In FIG. 10, reference numerals 23, 24 and 25 denote screw insertion holes, arrangement confirmation lines and positioning pieces, respectively.

On the other hand, similarly to the base V ₂ , the lid L ₂ is T-shaped in plan view, and can be viewed from both ends in the width direction of the T-shaped top wall 31 in the assembled state with the base V ₂ . , and a side wall 32 extending vertically toward the base 21 thereof, thereby providing a total of three connection ports J ₂ . 10, 33 denotes an assembly opening, and in FIG. 13, 34 denotes an assembly gap.

Then, as shown in FIG. 12(a), a total of three linear portions for each connection portion provided with each positioning piece 25 of the base V ₂ of the branch protection cover C ₂ fixed to the wall surface W ₁ After connecting each base V ₁₁ of the protective cover C ₁₁ , each base _{V 11} of the straight section protective cover C ₁₁ is connected via a cheese joint _N arranged on the base V ₂ of the branch protective cover C 2 . By connecting the piping material P placed on each of the straight portion protective covers C ₁₁ , each lid body L ₁₁ is made to cover each base V ₁₁ of each straight portion protection cover C 11 . Finally, as shown in FIG. 12(b), the branch pipe ends when the cover _L2 is placed over the base _V2 of the branch protection cover _C2 . As a result, flexural deformation permissible spaces _K2 are formed in portions corresponding to the assembly gaps 34 inside the lid _L2 and the notches 26 of the base portion 21, respectively.

The operation of releasing the engagement between the base V ₂ of the piped branch protection cover C ₂ and the lid body L ₂ is the same as that of the bend protection cover C ₁ of the first embodiment. That is, as shown in FIG. 13, the portion corresponding to the notch 26 of the base 21 in the portion near the assembly opening 33 of each of the inner and outer side walls 32 of one of the linear connecting portions of the branch protective cover _C2 is pressed. When the pressure F is applied, the outer side wall 32 is supported at both ends by the first and second fulcrum portions _R21 and _R22 , and the inner side wall 32 is cantilevered at the fulcrum portion _R21 . , are flexurally deformed due to the presence of the flexural deformation permissible space K ₂ , thereby forming tool insertion spaces A ₁ and _{A 1 '} respectively outside and inside the connection port J ₂ of the lid L 2 .

However, an engaging portion E22 is provided in the portion of the lid _L2 corresponding to the engaged portion _E21 of the standing wall 22 which is provided in the intermediate portion _of the linear connecting portion and is longer than the other portions. Instead, the vertical wall 22 at the intermediate portion of the linear connecting portion may function only as a fulcrum portion during bending deformation of the lid _L2 .

Next, with reference to FIGS. 14 to 16, the wall protection cover _C3 , which is the attached protection cover of Example 3 of the present invention, will be described. The wall protective cover _C3 is a protective cover used to cover and protect, together with the wall hole H, the bent portion of the piping material P drawn out to the wall surface through the wall hole H. It consists of a flat plate-like base _V3 fixed to the wall surface _W1 while covering H, and _a cover body _L3 integrally assembled to the base _V3 by engagement. Only one.

The flat plate-like base portion 41 that constitutes the base V ₃ has a total of three portions on both sides in the width direction and on the side opposite to the connection port J ₃ in a state where the lid body L ₃ is assembled to the base V ₃ . A pair of the side flange portion 41a and the opposite side flange portion 41b are protrudingly formed in each portion, so that the base portion 41 is wider than the narrow width portion 41c on the connection port _J3 side. A through hole 42 through which the piping material P is inserted is formed in the central portion. Standing walls 43a are formed at both end portions of the base portion 41 in the width direction of the entire base _V3 , and recessed engaged portions E are formed on the outer surface side of the base portion 41 on the outer surface of each standing wall 43a. ₃₁ are formed. Further, another vertical wall 43b is formed in a portion of the base portion 41 slightly inside the opposite flange portion 41b, and another engaged portion _E31 is formed on the outer surface of the vertical wall 43b. As a result, the base portion 41 of the base _V3 has a planar shape with no upward protrusions except for the three standing walls 43a and 43b. Screws B for fixing the base _V3 to the wall surface _W1 are inserted between the pair of vertical walls 43a and on both sides of the vertical wall 43b in the base 41, respectively. A hole 44 is formed.

On the other hand, the lid body _L3 is formed in a U-shaped cross section with the same width over the entire length, and is attached to both ends of the ceiling wall 51 in the width direction and attached to the base 41 of the base _V3 . A pair of side walls 52 are provided in series with each other, and the portion facing the connection port _J3 is closed with an opposing side wall 53 . Engagement portions _E32 to be engaged with the engaged portions _E31 of the base _V3 are formed on the inner side surfaces of the pair of side walls 52 and the opposing side wall 53, respectively, facing the assembly opening 54. there is Further, when the base _V3 and the lid _L3 are assembled, the predetermined length portion of each end surface 52a of the pair of side walls 52 of the lid _L3 on the connection port _J3 side is the base of the base _V3 . 41 and contacts the wall surface W ₁ , but the remaining end faces 52 a of the side walls 52 and the end face 53 a of the opposite side wall 53 both contact the upper surface of the base portion 41 directly. structure. In order to cope with this, a step portion 55 corresponding to the plate thickness of the base portion 41 of the base _V3 is provided on the end face 52a of each side wall 52 of the lid _L3 .
