JP7572924B2 - Pillar garnish - Google Patents

Description

This specification discloses a pillar garnish, which is an interior component that is attached to a pillar.

Vehicles are provided with pillars, which are window pillars. For example, front pillars are provided at both ends of the windshield glass in the vehicle width direction. A pillar garnish is attached to such pillars as an interior component. The pillar garnish is also called a pillar cover, and is attached to the pillar from the passenger compartment side. The pillar garnish prevents the pillar from being exposed inside the passenger compartment.

For example, a conventional pillar garnish is configured with a generally C-shaped cross section surrounding the pillar, with a portion of it facing the windshield glass. In Patent Document 1, for example, of the surfaces of the pillar garnish exposed to the passenger compartment, at least the surface facing the windshield glass is made into a low-reflection surface that does not easily reflect light. For example, this low-reflection surface is colored black or similar. By making the surface facing the windshield glass a low-reflection surface, the reflection of the low-reflection surface on the windshield glass is suppressed.

On the other hand, the surfaces of the pillar garnish exposed to the passenger compartment, other than the non-reflective surfaces, that face the passenger compartment are painted a white color such as ivory. By painting the surfaces that face the passenger compartment a light color, the interior of the vehicle can be kept bright.

By the way, it is possible to expand the field of view in front of the vehicle interior by changing the shape of the pillar garnish from a roughly C-shaped cross section to a polyhedral structure with multiple faces. For example, part of the pillar garnish, particularly the part near the windshield glass, can be made into a concave section that is recessed toward the center of the pillar, suppressing the protrusion inward in the vehicle width direction, thereby expanding the field of view in front of the vehicle interior.

This specification discloses a pillar garnish that can make the pillar garnish appear visually slimmer by improving the three-dimensional effect of the polyhedral pillar garnish.

The pillar garnish disclosed in this specification is attached to the front pillar from the passenger compartment side. Here, the front pillar is a pillar member provided at both ends of the windshield glass in the vehicle width direction and supporting the windshield glass. The pillar garnish has a concave portion and a convex portion. The concave portion has at least a part of its exposed surface facing the windshield glass and has a cross-sectional concave shape that is concave toward the center of the front pillar. The convex portion has a front end connected to the rear end of the concave portion and has a cross-sectional convex shape that surrounds the front pillar and protrudes outward from the center of the front pillar. In addition, a high-brightness color is applied to one of the exposed surfaces of the concave portion and the convex portion, and a low-brightness color is applied to the other. Furthermore, a colored boundary line that is a boundary line between the high-brightness color and the low-brightness color is provided in the boundary region between the concave portion and the convex portion.

According to the above configuration, the exposed surfaces of the concave and convex portions are colored in low and high brightness colors. This color scheme enhances the apparent difference in brightness between the concave and convex portions, and produces a visual effect of darkening the shadows, particularly on the surfaces that are colored in low brightness. This produces a visual effect that enhances the three-dimensional effect, making the angle between the concave and convex portions appear smaller (tighter) than it actually is.

In the above configuration, the boundary region may have an arc-shaped cross section. In this case, a groove is formed in the boundary region as a color boundary line.

According to the above configuration, when the boundary area between the concave and convex portions is a so-called R-curved surface and the boundary area has a specified width, the groove indicates where within that width the color boundary line should be set. If the color boundary line is indicated by paint instructions such as color markings, there is a risk that the color boundary line will be overpainted during the painting process of the concave and convex portions and disappear, but by indicating the color boundary line by the groove, which is a three-dimensional shape, the boundary line can be recognized even during the painting process.

In the above configuration, the exposed surface of the concave portion may be colored with a low brightness, while the exposed surface of the convex portion may be colored with a high brightness. In this case, a groove is formed in the boundary region rearward of the outermost end that protrudes most inward in the vehicle width direction.

With the above configuration, a high-brightness color is applied to the rear of the vehicle from the outermost end of the boundary area, making it possible to suppress reflection of the high-brightness color on the windshield glass.

In the above configuration, the pillar garnish may include a skin material having an exposed surface and a base material on which the skin material is laminated. In this case, the groove is formed by separating the skin material to which a low-brightness color is applied and the skin material to which a high-brightness color is applied.

The above configuration makes it possible to omit the process of forming color boundary lines on the surface by cutting or the like.

In the above configuration, the concave portion and the convex portion may be formed from separate parts. In this case, the concave portion is formed from a resin containing a paint of a low brightness color, and the convex portion is formed from a resin containing a paint of a high brightness color.

The above configuration makes it possible to omit the process of painting the high-brightness and low-brightness surfaces. If the high-brightness and low-brightness surfaces have been subjected to a surface treatment such as embossing, there is a risk that the unevenness of the surface will be filled in by painting. However, by avoiding painting, it is possible to maintain the surface treatment of the high-brightness and low-brightness surfaces in good condition.

In the above configuration, the convex portion may be formed with a flange that supports the concave portion. In this case, a plurality of bosses, which are a plurality of protrusions, are provided on the back surface of the concave portion that faces the flange. A plurality of boss holes into which the bosses are inserted are formed on the front surface of the flange of the convex portion that faces the back surface. Furthermore, the bosses and boss holes are arranged in a staggered manner along the longitudinal direction of the concave portion and the convex portion, with their widthwise positions differing front to back. After the bosses are inserted into the boss holes, they are fixed by ultrasonic welding.

When the pillar garnish houses a curtain shield airbag, the pillar garnish is deformed when the airbag deploys. In this case, by arranging the boss holes in a staggered pattern, compared to a linear arrangement, it is less likely that breaks will occur in the welded portions between the staggered boss holes and the bosses, and it is possible to suppress the progression of cracks that occur between the staggered boss holes. As a result, it is possible to suppress the separation of the concave portion from the convex portion.

The pillar garnish disclosed in this specification makes it possible to visually make yourself appear slimmer by improving the three-dimensional effect of the polyhedral structure.

FIG. 13 is a diagram illustrating an example of a front view of a vehicle interior on which a pillar garnish according to a third modified example of the present embodiment is mounted. FIG. 13 is a perspective view illustrating a pillar garnish according to a third modified example of the present embodiment (in an assembled state). FIG. FIG. 13 is a perspective view (disassembled) illustrating a pillar garnish according to a third modified example of the present embodiment. This is a cross-sectional view taken along line B-B of FIG.

Figure 1 shows a perspective view illustrating the configuration of the front of the passenger compartment and the outer side in the vehicle width direction. Figure 2 shows a cross-sectional view taken along line A-A in Figure 1. Note that in Figure 2, the door glass of the door 56 and its frame are omitted for the sake of simplicity. In Figure 2, the front direction of the vehicle is indicated by the FR axis, and the right direction of the vehicle width is indicated by the RH axis.

Note that Figures 1 and 2 only show the front pillar 10 and its surrounding structure located on the right side of the vehicle interior, but due to the symmetry of the vehicle structure, the left side also has the same structure as Figures 1 and 2, or more precisely, a line-symmetric structure.

A windshield glass 54 is provided at the front end of the vehicle compartment across the entire width of the vehicle. Front pillars 10 (see FIG. 2), which are window pillar members that support the windshield glass 54, are provided at both ends of the windshield glass 54 in the vehicle width direction.

In FIG. 1, the front pillar 10 is covered by a pillar garnish 30, but it extends from the front of the vehicle to the rear, slanting upward. The front pillar 10 functions as a framework for the passenger compartment, and its lower end is connected to a cowl side panel (not shown). The upper end of the front pillar 10 is connected to a roof rail (not shown), which is a framework for the passenger compartment ceiling. In FIG. 1, the roof rail is covered by a roof head lining 52, which is an interior component for the passenger compartment ceiling.

In addition, instead of the example shown in FIG. 1, for example in an open-top car with no roof inside the vehicle, the upper end of the front pillar 10 is not connected to other frame members and supports the windshield glass 54 independently.

Referring to FIG. 2, the front pillar 10 is a hollow pillar with a closed cross-sectional structure in which an inner panel 20 and an outer panel 22 are joined. Furthermore, a reinforcement member 24 is provided between the inner panel 20 and the outer panel 22. The inner panel 20, the outer panel 22, and the reinforcement 24 are made of a highly rigid material such as high tensile steel.

The outer end of the windshield glass 54 in the vehicle width direction is fixed to the flange 22A provided on the inner side of the outer panel 22 in the vehicle width direction via adhesive 28. In addition, a weather strip 26 is fixed to the flange 10A at the rear end of the front pillar 10. The weather strip 26 is sandwiched between the front pillar 10 and the front end of the door 56 (see Figure 1) and seals the gap between them.

The pillar garnish 30 is an interior component that is attached to the front pillar 10 from the passenger compartment side and covers the front pillar 10. With reference to the dashed-dotted circle in FIG. 2, for example, the pillar garnish 30 has a multi-layer structure in which a skin material 48 is laminated onto a base material 46. The surface of the skin material 48, i.e., the surface opposite the surface that contacts the base material 46, is the exposed surface that is exposed to the passenger compartment.

The base material 46 is the base part that maintains the shape of the pillar garnish 30, and is formed, for example, by injection molding a resin material. The skin material 48 is a member that has an exposed surface that is a design surface, and is composed, for example, of a sheet-like synthetic leather made of a resin material. The skin material 48 is fixed to the base material 46, for example, by using an adhesive.

2, the pillar garnish 30 has a generally J-shaped cross section, and its front end of the front pillar 10 is adjacent to the windshield glass 54 with a small gap. The outer end of the pillar garnish 30 in the vehicle width direction is connected to the flange 10A of the front pillar 10 via a weather strip 26. The pillar garnish 30 is fastened to the front pillar 10 via a fastening member such as a clip (not shown).

As shown in FIG. 2, a gap is provided between the pillar garnish 30 and the inner panel 20, which is the component of the front pillar 10 facing the passenger compartment. A curtain shield airbag 60 and wiring (not shown) are arranged in this gap. For example, the wiring extends from a battery provided in the engine compartment to electrical equipment such as a map lamp and center lamp provided on the passenger compartment ceiling.

The pillar garnish 30 according to this embodiment has a polyhedral structure including a concave portion 32 and a convex portion 34. At least a portion of the exposed surface of the concave portion 32 faces the windshield glass 54, and has a cross-sectional concave shape that is concave toward the center C1 of the front pillar 10.

The center C1 of the front pillar 10 conceptually refers to the central portion of the hollow front pillar 10. More specifically, in the cross section of FIG. 2, the center C1 is the center (centroid or geometric center) of the surface surrounded by the inner panel 20 and the outer panel 22.

For example, the concave surface 32 extends from its rear end to its front end outward in the vehicle width direction, with a cross-sectional arc shape. In other words, the concave surface 32 is positioned so that when the pillar garnish 30 is viewed from the vehicle interior, the field of view through the windshield glass 54 is expanded from the front to the back.

The front end of the convex portion 34 is connected to the rear end of the concave portion 32. The convex portion 34 has a convex cross-sectional shape that surrounds the front pillar 10 and protrudes outward from the center C1 of the front pillar 10. For example, the convex portion 34 extends from its front end in a curve toward the rear of the vehicle and outward in the vehicle width direction. The outer end of the convex portion 34 in the vehicle width direction abuts against the weather strip 26.

Figure 2 shows the vehicle longitudinal direction lengths L2, L3 of the concave surface portion 32 and the convex surface portion 34. The ratio L2:L3 of these lengths L2, L3 may be set between 4:6 and 6:4. In other words, the vehicle longitudinal direction lengths L2, L3 of the concave surface portion 32 and the convex surface portion 34 may be approximately equal.

Here, one of the exposed surfaces of the concave portion 32 and the convex portion 34 is painted with a high-brightness color, and the other is painted with a low-brightness color. For example, in the example of FIG. 1, the exposed surface of the concave portion 32 is the low-brightness surface 42, and the exposed surface of the convex portion 34 is the high-brightness surface 44. For example, black is used as the low-brightness color, and ivory or off-white is used as the low-brightness color.

By color-coding the concave surface 32 and the convex surface 34 into a low-brightness surface 42 and a high-brightness surface 44, the apparent difference in brightness between the concave surface 32 and the convex surface 34 is enhanced. This provides a visual effect in which the shadows of the low-brightness surface 42 are particularly darkened, and this provides a visual effect that enhances the three-dimensional effect, such as making the angle between the concave surface 32 and the convex surface 34 appear narrower than it actually is.

In addition, by making the exposed surface of the concave portion 32 that faces the windshield glass 54 a low-brightness surface 42, reflection from the concave portion 32 onto the windshield glass 54 is suppressed. In addition, by making the exposed surface of the convex portion 34 a high-brightness surface 44 that gives a feeling of lightness, the visual feeling of oppression felt by the occupants is reduced.

An enlarged view of the boundary region 35 between the concave portion 32 and the convex portion 34 is illustrated in the dashed-dotted circle on the left side of Figure 2. The front end 34A of the convex portion 34 is connected at an angle to the rear end 32A of the concave portion 32. For example, the angle formed by the rear end 32A of the concave portion 32 and the front end 34A of the convex portion 34 is an obtuse angle. The bent portion between the rear end 32A of the concave portion 32 and the front end 34A of the convex portion 34 forms the boundary region 35.

In other words, the concave surface portion 32 and the convex surface portion 34 are not connected in an angular manner, but are connected in a so-called rounded state. The rounded portion of this arc-shaped cross section becomes the boundary region 35. For example, this rounded portion is specified in the drawing, and this specified region becomes the boundary region 35.

A color boundary line is provided in this boundary region 35, which is a boundary line between the low-brightness surface 42 and the high-brightness surface 44. In the pillar garnish 30 according to this embodiment, a groove 36 is formed in the skin material 48 as this color boundary line.

For example, when the color boundary line is drawn with paint or the like, there is a risk that the color boundary line will be overpainted with high- and low-brightness paints and disappear when painting the low- and high-brightness surfaces 42 and 44. By forming the color boundary line as a groove 36, which has a three-dimensional shape, as in this embodiment, it is possible to prevent the color boundary line from disappearing during the painting process.

The width of groove 36 is determined to be shorter than the cross-sectional arc length of boundary region 35. For example, groove 36 is formed so that the groove width is 20% or less of the cross-sectional arc length of boundary region 35. For example, the width of groove 36 is determined to be 5 mm or less. By forming groove 36, it becomes clear where within boundary region 35, which has an extent equal to the cross-sectional arc length, the color boundary line is to be.

For example, in the example of FIG. 2, grooves 36 are cut into the surface (exposed surface) of skin material 48 with a tool or the like. Also, in the example of FIG. 3, a convex protrusion is provided on a mold for molding skin material 48, and grooves 36 are formed in skin material 48 by transferring this.

In addition, in FIG. 4, two types of skin materials 48, a low-brightness skin material 48A and a high-brightness skin material 48B, are produced in advance, and their ends are separated to form the groove 36. For example, when attaching the low-brightness skin material 48A and the high-brightness skin material 48B to the substrate 46, a spacer having a thickness equal to the width of the groove 36 is placed, and the ends of the low-brightness skin material 48A and the high-brightness skin material 48B are abutted against the spacer. The spacer is then removed to form the groove 36 between the low-brightness skin material 48A and the high-brightness skin material 48B.

In this case, the exposed surface (to the vehicle interior) of the low-brightness skin material 48A may be rougher than the exposed surface of the high-brightness skin material 48B. By roughening the exposed surface of the low-brightness skin material 48A, the so-called gloss value (luster level) is reduced, making it possible to further suppress reflections on the windshield glass 54.

Returning to FIG. 2, in the pillar garnish 30 according to this embodiment, the groove 36, which is the color boundary line, is formed rearward of the outermost end 31 of the pillar garnish 30. Here, the outermost end 31 of the pillar garnish 30 refers to the portion of the pillar garnish 30 that protrudes furthest inward in the vehicle width direction. As illustrated in FIG. 2, the tangent L1 of the outermost end 31 is parallel to the vehicle longitudinal axis FR.

By providing a groove 36, which is a color boundary line, in the rear portion of the outermost end 31, the high-brightness surface 44 is formed in the rear portion of the outermost end 31. The tangent line L1 of the outermost end 31 is parallel to the vehicle longitudinal axis FR, and the high-brightness surface 44 behind that faces away from the windshield glass 54, for example, toward the inside and rear of the vehicle width direction. As a result, reflection of the high-brightness surface 44 on the windshield glass 54 is suppressed.

As illustrated in FIG. 2, the groove 36 is formed near the rear end of the boundary region 35. In general, it is considered to provide a color boundary line at the midpoint of the boundary region 35. In contrast, in the pillar garnish 30 according to this embodiment, the groove 36, which is the color boundary line, is formed at a position offset from the midpoint of the boundary region 35 in order to suppress reflection of the high-brightness surface 44 on the windshield glass 54.

<Another example of pillar garnish 1>
Fig. 5 illustrates a pillar garnish 30 according to another example of the present embodiment. Compared to the example in Fig. 1, in the pillar garnish 30 in Fig. 5, the exposed surface of the concave portion 32 is a high-brightness surface 44, and the exposed surface of the convex portion 34 is a low-brightness surface 42. The other structures may be similar to those in Figs. 1 to 4.

Even with this structure, the apparent difference in brightness between the concave surface 32 and the convex surface 34 is enhanced by color-coding the concave surface 32 and the convex surface 34 into low brightness surfaces 42 and high brightness surfaces 44. This provides a visual effect that enhances the three-dimensional effect, making the angle between the concave surface 32 and the convex surface 34 appear narrower than it actually is.

Here, the exposed surface of the concave portion 32 becomes the high-brightness surface 44, and the high-brightness surface 44 is reflected on the windshield glass 54. However, as shown in FIG. 2, the concave portion 32 is positioned so as to be pulled outward in the vehicle width direction, and since the exposed surface is concave, the reflection on the windshield glass 54 is limited to the outer portion of the glass in the vehicle width direction, and the reduction in the driving field of vision is suppressed.

<Another example of pillar garnish 2>
2 to 4, the pillar garnish 30 has a two-layer structure including the substrate 46 and the skin material 48, but the pillar garnish 30 according to this embodiment may have a single-layer structure of the substrate 46. For example, during molding, the low-lightness surface 42 of the substrate 46 that is exposed to the vehicle interior is roughened relative to the high-lightness surface 44. Furthermore, a groove 36 is formed as a color boundary line between the low-lightness surface 42 and the high-lightness surface 44. Using the groove 36 as a mark, a low-lightness paint such as black is applied to the low-lightness surface 42, and a high-lightness paint such as ivory or white is applied to the high-lightness surface 44.

<Pillar Garnish Example 3>
6 to 9 show another example of the pillar garnish according to the present embodiment. In this example, the concave portion 32 and the convex portion 34 of the pillar garnish 30 are formed as separate parts and are assembled together.

Figure 7 shows an assembly diagram of the pillar garnish 30 alone, and Figure 8 shows an exploded diagram of the pillar garnish 30 alone. In this example, a flange 34G that supports the concave portion 32 is formed on the convex portion 34, with the convex portion 34 functioning as a main plate and the concave portion 32 functioning as a separate plate.

The concave surface portion 32 and the convex surface portion 34 may each have a single-layer structure made of a single layer of substrate. The substrate is then colored in such a way that the concave surface portion 32 is made of a resin containing a low-brightness paint, and the convex surface portion 34 is made of a resin containing a high-brightness paint.

For example, when forming the concave surface portion 32, a low-brightness paint such as black is mixed into the resin, and then the resin is molded. As a result, the entire concave surface portion 32, including the low-brightness surface 42, is colored a low-brightness color. Similarly, when forming the convex surface portion 34, a high-brightness paint such as white or ivory is mixed into the resin, and then the resin is molded. As a result, the entire convex surface portion 34, including the high-brightness surface 44, is colored a high-brightness color.

In this way, by mixing low- or high-brightness paint into the base resin, the process of painting the low-brightness surface 42 and the high-brightness surface 44 can be omitted. Furthermore, if surface treatment such as embossing is applied to the low-brightness surface 42 and the high-brightness surface 44 when molding the concave surface 32 and the convex surface 34, the spraying of the paint may flatten the surface irregularities and create a smooth surface. In contrast, in the example of Figures 6 to 9, painting the low-brightness surface 42 and the high-brightness surface 44 is avoided, making it possible to maintain the surface treatment such as embossing.

The flange 34G of the convex portion 34 is a flat plate that supports the concave portion 32, which is a separate plate. The flange 34G is formed so as to be recessed from the high-brightness surface 44 toward the rear side. The side wall 34D, which is the boundary between the flange 34G and the high-brightness surface 44 and connects the step between them, is formed in a shape that follows the side wall 32C of the concave portion 32.

The side wall 34D also has a number of claw holes 34F drilled along its longitudinal direction. As described below, the claws 32D provided on the side wall 32C of the concave portion 32 are inserted into the claw holes 34F.

Furthermore, a plurality of pedestals 34B are provided on the surface of the flange 34G that faces the concave portion 32 (its back surface). A boss hole 34C is drilled in the thickness direction in the top surface of each pedestal 34B. As described later, a boss 32F provided on the back surface of the concave portion 32 that faces the flange 34G is inserted into the boss hole 34C.

The pedestals 34B (and boss holes 34C) are formed in multiple locations along the longitudinal direction of the flange 34G. Here, the pedestals 34B are arranged in a staggered manner such that their widthwise positions differ between the front and rear along the longitudinal direction of the flange 34G. As described below, this staggered arrangement prevents the concave surface portion 32 from breaking and separating from the convex surface portion 34 when the curtain shield airbag 60 (see FIG. 9) is deployed.

The concave portion 32 is a flat-plate-shaped component, and a plurality of bosses 32F, which are protrusions protruding from the back surface that faces the flange 34G, are provided on the back surface. The bosses 32F are arranged in a manner that corresponds to the boss holes 34C of the convex portion 34, and are arranged in a staggered manner along the longitudinal direction of the concave portion 32, with their widthwise positions differing between the front and rear.

Also, side wall 32C (hidden surface in FIG. 8) that faces side wall 32B visible in FIG. 8 has multiple claws 32D provided along its longitudinal direction. These claws 32D are provided at positions corresponding to claw holes 34F of convex portion 34.

When assembling the pillar garnish 30, first the claws 32D of the concave portion 32 are inserted into the claw holes 34F of the convex portion 34, while the boss 32F is inserted into the boss hole 34C. The base 34B and the boss 32F are then welded together by ultrasonic welding or the like. This fixes the concave portion 32 to the convex portion 34.

Referring to Figures 8 and 9, in the boundary region 35 between the concave portion 32 and the convex portion 34, a groove 36, which is a color boundary line, is formed by the gap between the ridge line of the side wall 32C of the concave portion 32 and the ridge line of the side wall 34D of the convex portion 34.

As shown in FIG. 9, the pillar garnish 30 houses a curtain shield airbag 60 therein. When the curtain shield airbag 60 deploys, it detaches the pillar garnish 30 from the front pillar 10 and deploys into the vehicle cabin. Specifically, the outer end of the convex portion 34, which is sealed by the weather strip 26, in the vehicle width direction passes over the seal of the weather strip and expands toward the vehicle cabin, forming a gap. The curtain shield airbag 60 deploys through this gap into the vehicle cabin. At this time, the pillar garnish 30 is held away from the front pillar 10 by a preset stroke by a tether clip (not shown), preventing the pillar garnish 30 from scattering into the vehicle cabin.

To prevent the pillar garnish 30 from separating into the concave portion 32 and the convex portion 34 when the curtain shield airbag 60 is deployed, the concave portion 32 is provided with a tab 32D and a boss 32F, and the convex portion 34 is provided with a boss hole 34C.

When the curtain shield airbag 60 is deployed, the pillar garnish 30 is biased in its thickness direction. The claws 32D extend in the width direction, which is approximately perpendicular to the biasing direction, and when the pillar garnish 30 is biased in the thickness direction, the claws 32D are caught in the claw holes 34F. This prevents the concave portion 32 from coming off the convex portion 34.

When the curtain shield airbag 60 is deployed, the pillar garnish 30 is deformed. If the deformation amounts of the convex portion 34 and the concave portion 32 are different, a load is applied to the base 34B, which is the fixed point of the convex portion 34 with the concave portion 32. If this load becomes excessive, the base 34B breaks. By arranging the boss holes 34C and the bosses 32F in a staggered manner, compared to the case of a linear arrangement, it is less likely that breaks will occur in the welded portions between the staggered boss holes 34C and the bosses 32F, and the progression of cracks that occur between the staggered boss holes 34C, 34C can be suppressed. As a result, it is possible to suppress the detachment of the concave portion from the convex portion.

For example, if the boss holes 34C are arranged in a straight line on the flange 34G, there is a risk that a fracture of one pedestal 34B will cause a linear crack to form, resulting in a chain reaction of fracture of the other pedestals 34B. On the other hand, by arranging the pedestals 34B in a staggered arrangement, the extension direction of a crack that occurs between adjacent pedestals 34B, 34B differs from the extension direction to the adjacent pedestal 34B, making it difficult for the cracks to link together. As a result, fracture of the flange 34G is suppressed, and further separation of the concave portion 32 from the convex portion 34 is suppressed.
