  Hereinafter, modes for carrying out the present invention will be described.

  FIG. 1 shows an example of a protruding corner member 1 of the present embodiment. The protruding corner member 1 is formed in a substantially L-shaped cross section by connecting a pair of substrates 2. Here, the substantially L-shaped cross section means that the angle (recess angle) between the back surfaces of the pair of substrates 2 is 60 to 120 °. The angle between the back surfaces of the pair of substrates 2 (inferior angle) is preferably 80 to 100 °, and more preferably 90 °.

  An uneven pattern 15 is formed on the surface of the substrate 2. As shown in FIG. 2, the concave / convex pattern 15 is formed by adjoining a convex pattern 3 formed so as to protrude from the surface of the substrate 2 and a concave pattern 4 formed concavely on the surface of the substrate 2. Yes. The substrate 2 is formed in a rectangular shape. For example, the substrate 2 is formed in a strip shape in which the long side 17 is relatively long with respect to the short side 18. The substrate 2 is formed of an inorganic board containing cement, a wooden board, a resin board, or the like. In addition, it is preferable that the back surface of the board | substrate 2 is formed in the flat surface.

  Of the two side end surfaces, the substrate 2 has at least one side end surface formed as an inclined surface 6. Here, the side end surface of the substrate 2 can be an end surface substantially parallel to the long side 17 of the substrate 2. The inclined surface 6 is formed to be inclined at a substantially constant angle with respect to the thickness direction of the substrate 2. The inclined surface 6 is formed such that the width dimension of the front surface of the substrate 2 is larger than the width dimension of the back surface of the substrate 2. That is, the angle (dominant angle) formed by the surface of the substrate 2 and the inclined surface 6 is formed larger than the angle (dominant angle) formed by the back surface of the substrate 2 and the inclined surface 6. The inclination angle of the inclined surface 6 with respect to the thickness direction of the substrate 2 can be appropriately set according to the size of the angle between the back surfaces of the pair of substrates 2 as described above. The inclination angle of the inclined surface 6 is 45 °.

  The pair of substrates 2 are connected by joining the inclined surfaces 6 to each other. The inclined surface 6 is bonded and bonded with an adhesive containing a polymerizable compound such as a urethane prepolymer, for example. And after connecting and unifying a pair of board | substrates 2, the projecting corner member 1 is made by coating over the full length of the connection part (corner part of the projecting corner side) 10 of a pair of board | substrate 2 as needed. Is formed.

  The protruding corner member 1 includes a contact 25 of the tangent line 8 on the ridge line 7 of one substrate 2, a vertical line 26 passing through the contact 25, and the other substrate 2 over substantially the entire length of the connection portion 10 of the pair of substrates 2. The distance L from the intersection 27 with the ridge line 7 is 5 mm or less. The ridge line 7 is formed by a boundary line between the surface of the substrate 2 and the inclined surface 6. That is, the ridge line 7 is a line formed by the edge of the long side 17 on the surface of the substrate 2. Since the uneven pattern 15 is formed on the surface of the substrate 2, the ridge line 7 is not formed in a straight line over the entire length.

  FIG. 3 illustrates a part of the connecting portion 10. In this case, in a certain section, the ridge line 71 of the first substrate (one substrate) 21 is located on the inner side (lower side) than the ridge line 72 of the second substrate (other substrate) 22. That is, the ridge line 72 of the second substrate 22 is located on the outer side (upper side) of the ridge line 71 of the first substrate 21. Further, in another section, the ridge line 71 of the first substrate (one substrate) 21 is located on the outer side (upper side) of the ridge line 72 of the second substrate (the other substrate) 22. That is, the ridge line 72 of the second substrate 22 is located on the inner side (lower side) than the ridge line 71 of the first substrate 21. In the vicinity of the center of the portion, the ridgeline 72 of the second substrate 22 is formed between the adjacent convex patterns 3 of the first substrate 21, and the outer side (upper side) of the concave pattern 4 of the first substrate 21. The ridgeline 72 of the second substrate 22 is located at the top. A tangent line 81 to the ridge line 71 of the first substrate 21 is assumed, a vertical line 26 passing through the contact point 25 of the tangent line 81 is assumed, and an intersection point 27 between the vertical line 26 and the ridge line 72 of the second substrate 22 is defined. Assuming that the distance L between the contact point 25 and the intersection point 27 is 5 mm or less. Also, in the vicinity of both sides near the center of the part, a tangent line 82 to the ridge line 72 of the second substrate 22 is assumed contrary to the vicinity of the center, and a vertical line 29 passing through the contact 28 of the tangent line 82 is assumed. Assuming an intersection 30 between the vertical line 29 and the ridge line 71 of the first substrate 21, the distance L between the contact 28 and the intersection 30 is formed to be 5 mm or less.

  Further, the projecting corner member 1 has an intersection 11 between an arbitrary parallel line 9 with respect to the short side 18 of the substrate 2 and the ridge line 7 of one substrate 2 and the parallel in the entire length of the connection portion 10 of the pair of substrates 2. The distance S between the line 9 and the intersection 12 of the ridge line 7 of the other substrate 2 is formed to be 5 mm or less. The ridge line 7 is formed by a boundary line between the surface of the substrate 2 and the inclined surface 6. That is, as described above, the ridge line 7 is a line formed by the edge of the long side 17 on the surface of the substrate 2. Since the uneven pattern 15 is formed on the surface of the substrate 2, the ridge line 7 is not formed in a straight line over the entire length.

  FIG. 4 illustrates a part of the connection portion 10 of the pair of substrates 2. In this case, in a certain section, the ridge line 71 of the first substrate (one substrate) 21 is located on the inner side (lower side) than the ridge line 72 of the second substrate (other substrate) 22. That is, the ridge line 72 of the second substrate 22 is located on the outer side (upper side) of the ridge line 71 of the first substrate 21. Further, in another section, the ridge line 71 of the first substrate (one substrate) 21 is located on the outer side (upper side) of the ridge line 72 of the second substrate (the other substrate) 22. That is, the ridge line 72 of the second substrate 22 is located on the inner side (lower side) than the ridge line 71 of the first substrate 21. In the vicinity of the center of the portion, the ridgeline 72 of the second substrate 22 is formed between the adjacent convex patterns 3 of the first substrate 21, and the outer side (upper side) of the concave pattern 4 of the first substrate 21. The ridgeline 72 of the second substrate 22 is located at the top. Then, assuming an arbitrary parallel line 9 with respect to the short side 18 of the first substrate 21 or the short side 18 of the second substrate 22, the intersection 11 of the parallel line 9 and the ridge line 71 of the first substrate 21, Assuming the intersection 12 of the parallel line 9 and the ridgeline 72 of the second substrate 22, the distance S between the intersection 11 and the intersection 12 is formed to be 5 mm or less. Further, in the vicinity of both sides near the center of the portion, the ridgeline 71 of the first substrate 21 is located outside (upper) the concave handle 4 of the second substrate 22, contrary to the vicinity of the center. Then, assuming an arbitrary parallel line 9 with respect to the short side 18 of the first substrate 21 or the short side 18 of the second substrate 22, the intersection 11 of the parallel line 9 and the ridge line 71 of the first substrate 21, Assuming the intersection 12 of the parallel line 9 and the ridgeline 72 of the second substrate 22, the distance S between the intersection 11 and the intersection 12 is formed to be 5 mm or less.

  The distance L and the distance S do not have to be constant over the entire length of the connection portion 10 of the pair of substrates 2 and may be in the range of 0 mm or more and 5 mm or less. When the distance L and the distance S are 0 mm over the entire length of the connection portion 10, the ridge line 71 of the first substrate 21 and the ridge line 72 of the second substrate 22 coincide with each other over the entire length of the connection portion 10. . Here, it is preferable that the positional relationship between the ridge line 71 of the first substrate 21 and the ridge line 72 of the second substrate 22 is not constant. That is, it is preferable that the ridge line 71 of the first substrate 21 is not located outside (upper side) of the ridge line 72 of the second substrate 22 over the entire length of the connection portion 10 of the pair of substrates 2. Conversely, it is preferable that the ridge line 71 of the first substrate 21 is not located on the inner side (lower side) of the ridge line 72 of the second substrate 22 over the entire length of the connection portion 10 of the pair of substrates 2. That is, it is preferable that the inner and outer (upper and lower) positional relationships between the ridge line 71 of the first substrate 21 and the ridge line 72 of the second substrate 22 are partially switched at the connection portion of the pair of substrates 2. When the positional relationship between the ridge line 71 and the ridge line 72 is partially switched in this way, both the ridge line 71 of the one substrate 21 and the ridge line 72 of the other substrate 22 appear in the connection portion 10. Thus, both the ridge line 71 and the ridge line 72 are simultaneously recognized from both sides of the protruding corner member 1 across the connection portion 10 of the pair of substrates 2, and the connection portion 10 is unlikely to be a monotonous uneven pattern 15. The appearance of the protruding corner member 1 is unlikely to deteriorate.

  The protruding corner member 1 may be joined with the inclined surfaces 6 of the pair of substrates 2 being slightly shifted from each other. However, when the distance L or the distance S is 5 mm or less, the inclined surfaces 6 are connected to each other. The misalignment (positional misalignment) can be made inconspicuous. Therefore, even if the chamfering operation is not performed or hardly performed on the connection portion 10 of the pair of substrates 2 after the pair of substrates 2 are connected, the design of the appearance of the protruding corner member 1 is not easily impaired. Moreover, the production efficiency of the protruding corner member 1 is improved by performing no or almost no chamfering work on the connecting portion 10. In addition, when the distance L or the distance S is 5 mm or less, the projected corner member 1 loses the sense of unity between the uneven pattern 15 on the surface of one substrate 2 and the uneven pattern 15 on the surface of the other substrate 2. It is difficult and the design of the appearance is not easily impaired.

  As mentioned above, after connecting and integrating a pair of board | substrates 2, it coats over the full length of the connection part 10 of a pair of board | substrate 2, and may form the protrusion corner member 1. FIG. For example, when the surfaces of the pair of substrates 2 before connection are preliminarily coated, the connection portion 10 is coated with the same color as the surface of the base material 2 that has been preliminarily painted as an auxiliary coating. can do. And it is preferable that the coating film 13 formed by such auxiliary | assistant coating is formed over the surface side of the board | substrate 2 via the ridgeline 7 of a pair of board | substrate 2 from the exposed part 61 of the inclined surface 6. FIG. The exposed portion 61 of the inclined surface 6 is, for example, a part of the inclined surface 6 of the second substrate 22 located between the adjacent convex patterns 3 of the first substrate 21. Further, the exposed portion 61 of the inclined surface 6 is, for example, a part of the inclined surface 6 of the first substrate 21 located between the adjacent convex patterns 3 of the second substrate 22. The coating film 13 is formed so as to extend from the exposed portion 61 to the surface of the first substrate 21 beyond the ridge line 71 of the first substrate 21. The coating film 13 is formed so as to extend from the exposed portion 61 to the surface of the second substrate 22 beyond the ridge line 72 of the second substrate 22. Moreover, it is preferable that the coating film 13 is formed in the substantially strip | belt shape with the width dimension R being 3 mm or less on the basis of the ridgeline 7. FIG. That is, as shown in FIG. 5, a tangent line 8 to the ridge line 7 of the substrate 2 is assumed, and a perpendicular line 14 extending from the tangent line 8 to the surface side of the substrate 2 is assumed, and the length of the perpendicular line (that is, the width dimension of the coating film 13). Within a range where R) is 3 mm or less, the coating film 13 is preferably formed by auxiliary coating. By forming the coating film 13 by auxiliary coating in this way, the coating film 13 becomes difficult to be formed in a wide range, the coating film 13 becomes less conspicuous, and the appearance deterioration of the protruding corner member 1 can be reduced. Since the coating film 13 by auxiliary coating is also formed on the exposed portion 61 of the inclined surface 6 exposed at the connection portion 10, the waterproofness of the connection portion 10 can be improved. Further, after the vicinity of the boundary between the ridge line 7 located on the inner side and the inclined surface 6 exposed at the connection portion 10 is previously treated with putty, the coating film 13 by auxiliary coating may be formed.

  Hereinafter, the manufacturing method of the above-mentioned protruding corner member 1 is demonstrated.

  The protruding corner member 1 has a step in which the side end surface of the rectangular substrate 2 is formed on the inclined surface 6, and a step in which the adhesive 30 is applied from the application surface 32 of the coating device 31 to the inclined surface 6. And a step of bonding the inclined surfaces 6 of the pair of substrates 2 with the adhesive 30.

  As shown in FIG. 6, the pair of substrates 2 is preferably formed from a single original plate 5. In this case, it is easy to align the size of the pair of substrates 2 such as the plate thickness. In addition, it is easy to obtain a sense of unity in the uneven pattern 15 of the pair of substrates 2. As the original plate 5, it is preferable to use the same type of outer wall material as the outer wall material constructed together with the protruding corner member 1. In this case, it is easy to obtain a sense of unity between the concave / convex pattern 15 on the surface of the protruding corner member 1 and the concave / convex pattern 15 of the constructed outer wall material. For example, the plurality of substrates 2 are formed by cutting the strip-shaped original plate 5 along a cutting line 16 substantially parallel to the short side.

  Next, as shown in FIG. 7, at least one of the two side end surfaces of the substrate 2 is formed as the inclined surface 6. Here, the side end surface of the substrate 2 can be an end surface substantially parallel to the long side 17 of the substrate 2. When the substrate 2 is formed as shown in FIG. 6, the cut surface of the substrate 2 is the side end surface. The inclined surface 6 is formed to be inclined at a substantially constant angle with respect to the thickness direction of the substrate 2. The inclined surface 6 is formed such that the width dimension of the front surface of the substrate 2 is larger than the width dimension of the back surface of the substrate 2. That is, the angle (dominant angle) formed by the surface of the substrate 2 and the inclined surface 6 is formed larger than the angle (dominant angle) formed by the back surface of the substrate 2 and the inclined surface 6. The inclination angle of the inclined surface 6 with respect to the thickness direction of the substrate 2 can be appropriately set according to the size of the angle between the back surfaces of the pair of substrates 2 as described above. For example, the inclination angle of the inclined surface 6 with respect to the thickness direction of the substrate 2 is 45 °. The inclined surface 6 is formed by performing a cutting process or a cutting process on the side end surface of the rectangular substrate 2 so that a corner portion on the back surface side of the substrate 2 is cut off. The inclination angle of the inclined surface 6 of one substrate 2 and the inclination angle of the inclined surface 6 of the other substrate 2 may be the same or different.

  After the inclined surface 6 is formed as described above, the adhesive 30 is applied to the inclined surface 6 as shown in FIG. The adhesive 30 preferably contains a polymerizable compound such as a urethane prepolymer. The adhesive 30 is applied by a coating device 31. Examples of the coating device 31 include a coating roll 33. The coating device 31 has a coating surface 32 to which the adhesive 30 is attached. A substantially cylindrical or columnar application roll 33 has a peripheral surface formed as an application surface 32. The coating roll 33 is formed to be rotatable about a shaft 35. The supply of the adhesive 30 to the application surface 32 is performed, for example, by immersing the lower part of the application roll 33 in the adhesive 30 stored in the container 36.

  And application | coating of the adhesive agent 30 to the inclined surface 6 is performed as follows. First, the substrate 2 is disposed above the coating roll 33 with the inclined surface 6 in proximity to or in contact with the coating surface 32. At this time, the substrate 2 is held between the front and back by the holder 39. In addition, the substrate 2 and the coating roll 33 are arranged so that the longitudinal direction of the substrate 2 and the axis 35 of the coating roll 33 are substantially orthogonal to each other. Next, while the coating roll 33 rotates around the shaft 35, either one or both of the substrate 2 and the coating roll 33 are moved substantially parallel to the longitudinal direction of the substrate 2 (direction parallel to the long side 17). . Thereby, the adhesive 30 adhering to the application surface 32 is transferred and applied over the entire length in the longitudinal direction of the inclined surface 6 (the same as the longitudinal direction of the substrate 2). In addition, in a state where the plurality of substrates 2 are arranged in a direction parallel to the long side 17 and are held by the holder 39, either one or both of the substrate 2 and the coating roll 33 are placed in the longitudinal direction of the substrate 2 (parallel to the long side 17). May be moved substantially parallel to the other direction. In this case, the adhesive 30 can be applied to the inclined surfaces 6 of the plurality of substrates 2 by one movement.

  As shown in FIG. 9A, the application roll 33 is formed of a protrusion 34a and a groove 34b. The protrusion 34 a and the groove 34 b are formed over the entire circumference in the circumferential direction of the application roll 33. The plurality of protrusions 34 a and the plurality of grooves 34 b are formed alternately in the axial direction of the application roll 33 (longitudinal direction of the shaft 35). The outer peripheral surface 50 of the protrusion 34a is formed to protrude outward from the bottom surface 51 of the groove 34b. Therefore, the application surface 32 is formed as an uneven surface. The diameter of the application roll 33 at the protrusion 34a is substantially constant. The diameter of the application roll 33 at the groove 341 is also substantially constant. By forming the application surface 32 on the uneven surface, the adhesive 30 is easily held in the groove 34, and the adhesive 30 is more easily attached to the application surface 32 than the flat application surface 32. Easy to apply.

  Then, when applying the adhesive 30 to the inclined surface 6, as shown in FIG. 9B, the interval S1 between the tip 61 of the inclined surface 6 and the outer peripheral surface 50 of the protrusion 34a is the rear end 62 of the inclined surface 6 and the protrusion. The inclined surface 6 is inclined with respect to the outer peripheral surface 50 of the protrusion 34a so as to be narrower than the interval S2 with the outer peripheral surface 50 of 34a. Here, the tip 61 of the inclined surface 6 is a boundary portion between the surface of the substrate 2 and the inclined surface 6 and is a portion of the long side 17 on the inclined surface 6 side of the surface of the substrate 2. The rear end 62 of the inclined surface 6 is a boundary portion between the back surface of the substrate 2 and the inclined surface 6, and is a portion of the long side 17 on the inclined surface 6 side of the back surface of the substrate 2. The uneven pattern 15 is formed on the surface of the substrate 2 as described above, and the back surface of the substrate 2 is formed as a substantially flat surface.

  When the interval S1 between the tip 61 of the inclined surface 6 and the outer peripheral surface 50 of the protrusion 34a is smaller than the interval S2 between the rear end 62 of the inclined surface 6 and the outer peripheral surface 50 of the protrusion 34a, The amount of the adhesive 30 entering between the tip 61 and the application surface 32 is gradually smaller than the amount of the adhesive 30 entering between the rear end 62 of the inclined surface 6 and the application surface 32. Therefore, the amount of the adhesive 30 adhering to the tip 61 side of the inclined surface 6 decreases, and when the inclined surfaces 6 are joined together, the adhesive 30 protrudes from between the inclined surfaces 6 to the surface side of the substrate 2. Can be almost eliminated. Therefore, even if the corners of the connection portions 10 of the pair of substrates 2 are not chamfered, the adhesive 30 does not protrude or slightly protrudes from the surface side of the substrate 2. Can be suppressed.

  Here, the state in which the inclined surface 6 is inclined with respect to the application surface 32 is preferably that the angle θ between the inclined surface 6 and the outer peripheral surface 50 of the protrusion 34a is 0.3 to 0.9 °. . Thereby, when the inclined surfaces 6 are joined together, it is possible to prevent the adhesive 30 from protruding from between the inclined surfaces 6 to the surface side of the substrate 2. Moreover, it is preferable to set the space | interval S1 between the front-end | tip 61 of the inclined surface 6, and the outer peripheral surface 50 of the protrusion 34a to 0.3-0.9 mm. Thus, when the inclined surfaces 6 are joined, the adhesive 30 is hardly protruded from between the inclined surfaces 6 to the surface side of the substrate 2 without leaving an unbonded portion between the inclined surfaces 6. Can do. The protruding amount of the adhesive 30 is preferably 3 mm or less from the tip 61 of the joined inclined surface 6. In addition, the coating roll 33 may be a smooth one in which the protrusion 34a and the groove 34b are not formed.

  The interval S1 and the interval S2 are preferably formed so as to be adjustable according to the application amount, viscosity, and the like of the adhesive 30. Therefore, it is preferable that the coating roll 33 and the substrate 2 are formed so as to be able to approach and separate in a direction orthogonal to the axis 35 (indicated by an arrow 37 in FIG. 8), and as indicated by an arrow 38 in FIG. The coating roll 33 and the substrate 2 are preferably formed so as to be rotatable about a direction parallel to the long side 17.

  FIG. 10A shows another example of the application roll 33. The application roll 33 is formed such that a plurality of groove portions 34b arranged in a direction parallel to the shaft 35 gradually become deeper in one direction. The diameter of the application roll 33 at the protrusion 34a is substantially constant.

  Then, in applying the adhesive 30 to the inclined surface 6, as shown in FIG. 10B, the interval S1 between the tip 61 of the inclined surface 6 and the outer peripheral surface 50 of the protrusion 34a, the rear end 62 and the protrusion of the inclined surface 6 The inclined surface 6 is parallel to the outer peripheral surface 50 of the protrusion 34a so that the distance S2 between the outer peripheral surface 50 of 34a is the same. Thus, when the interval S1 between the tip 61 of the inclined surface 6 and the outer peripheral surface 50 of the protrusion 34a and the interval S2 between the rear end 62 of the inclined surface 6 and the outer peripheral surface 50 of the protrusion 34a become the same, the groove portion Since the depth of 34 b is shallower at the front end 61 than the rear end 62 of the inclined surface 6, the amount of the adhesive 30 that enters between the front end 61 of the inclined surface 6 and the application surface 32 is the rear end 62 of the inclined surface 6. And gradually less than the amount of adhesive 30 entering between the coating surface 32 and the coating surface 32. Therefore, the amount of the adhesive 30 adhering to the tip 61 side of the inclined surface 6 decreases, and when the inclined surfaces 6 are joined together, the adhesive 30 protrudes from between the inclined surfaces 6 to the surface side of the substrate 2. Can be almost eliminated. Therefore, even if the corners of the connection portions 10 of the pair of substrates 2 are not chamfered, the adhesive 30 does not protrude or slightly protrudes from the surface side of the substrate 2. Can be suppressed.

  The means for adjusting the coating amount of the adhesive 30 is not limited to these. In the application roll 33 having the groove 34b, it can be adjusted by changing the width of the groove, the distance between the grooves, and the like.

  As described above, after the adhesive 30 is applied to the inclined surfaces 6, the inclined surfaces 6 of the pair of substrates 2 are joined together. At this time, it is preferable to use a pedestal 40 having a substantially triangular cross section as shown in FIG. That is, the substrate 2 is placed on each of the two inclined surfaces 41 of the pedestal 40, and the inclined surfaces 6 of the substrate 2 are joined to each other on the upper side 42 of the pedestal 40. Thereby, alignment between the inclined surfaces 6 can be easily performed, and workability can be improved.

  11, after the inclined surfaces 6 of the substrate 2 are joined to each other on the upper side of the top portion 42 of the pedestal 40, the substrate 2 is pressed toward the inclined surface 41 with the pressing tool 43, and in this state, as shown in FIG. Thus, it is preferable to turn the substrate 2 upside down together with the base 40 and the pressing tool 43. As a result, even if the adhesive 30 between the joined inclined surfaces 6 is hardened until the adhesive 30 protrudes from between the inclined surfaces 6, the adhesive 30 tends to hang down from the front end 61 of the substrate 2, and the protrusion 30 protrudes. It becomes difficult for the adhesive 30 to adhere to the surface of the substrate 2. Accordingly, the surface of the substrate 2 is not easily soiled by the protruding adhesive.

  As described above, after the inclined surfaces 6 coated with the adhesive 30 are joined together, the inclined surfaces 6 are bonded together by the adhesive 30 being cured, and the pair of substrates 2 are connected and integrated. . Thereafter, as shown in FIG. 13, the adhesive 30 that has protruded and hardened to the connection portion (corner portion on the protruding corner side) 10 of the pair of substrates 2 is removed by the cutting tool 44 as necessary. As the cutting tool 44, a keren tool, a cutter, or the like can be used. The removal of the adhesive 30 may be performed only in a portion where the adhesive 30 that has protruded and hardened is conspicuous. Thereafter, as shown in FIG. 14, the protruding corner member 1 is formed by applying auxiliary coating to the connection portions 10 of the pair of substrates 2 as necessary. The auxiliary coating is preferably formed from the exposed portion 61 of the inclined surface 6 to the surface side of the substrate 2 via the ridge line 7 of the pair of substrates 2. For the auxiliary coating, a coating tool 45 such as a brush or a roller can be used.

  And in this Embodiment, the protrusion of the adhesive agent 30 can be decreased in the connection part 10 of a pair of board | substrate 2. FIG. Therefore, after connecting the pair of substrates 2, the step of chamfering the connection portion 10 of the pair of substrates 2 to remove the adhesive 30 is performed or is hardly performed. The appearance of 1 is difficult to be damaged. Moreover, the production efficiency of the protruding corner member 1 is improved by not performing the process for chamfering the connecting portion 10 or performing almost no process.
