Description

Technical Field

[0001] The present invention relates to a vehicle body structure of a vehicle such as an automobile, and more particularly to a vehicle body side structure at the front of the vehicle.

Background Art

[0002] As an example of a vehicle body structure of this type, the vehicle body structure described in Patent Document 1 is known. The vehicle body structure described in Patent Document 1 has a hinge pillar extending in the vertical direction. The hinge pillar has a pillar outer member having a substantially hat-shaped cross section and a plate-shaped pillar inner member that cooperates with the pillar outer member to form a substantially rectangular closed cross section extending upward. The pillar outer member and the pillar inner member are made of high-tensile steel or ultra-high-tensile steel. The pillar outer member is composed of a main body portion formed convexly outward in the vehicle width direction and a pair of front and rear flange portions extending forward and backward from the front end portion and the rear end portion of the main body portion, respectively. On the upper and lower portions of the main body portion, a pair of upper and lower hinge attachment portions bulging outward in the vehicle width direction are respectively formed for attaching a door hinge. Thus, the vehicle body structure disclosed in Patent Document 1 has a hinge pillar made of high-tensile steel or ultra-high-tensile steel, and a structure in which a door hinge is attached to the hinge pillar.

[0003] Generally, the vehicle width varies for each segment of a vehicle. However, in order to commonize the platform for different segments, the platform is designed based on the segment with a small vehicle width. Therefore, in order to accommodate a segment with a large vehicle width, it is necessary to cope with the increase in the vehicle width direction on the hinge pillar side.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, since the hinge pillar of the vehicle body structure disclosed in Patent Document 1 is made of high-tensile steel or ultra-high-tensile steel, when dealing with the increase in the vehicle width direction on the hinge pillar side, the difficulty level of formability increases. Therefore, it was not easy to deal with the increase in the vehicle width direction on the hinge pillar side. This is the same for the front door hinge reinforcement that is made of high-tensile steel and is arranged between the pillar outer member and the pillar inner member. On the other hand, although it is conceivable to change the platform for each different segment, the platform cannot be made common and the cost increases.

[0006] The present invention has been made in view of the above actual situation, and its object is to provide a vehicle body side structure that can easily cope with the increase in the vehicle width direction for a large vehicle width segment even when using a platform made common for different segments.

Means for Solving the Problems

[0007] One aspect of the present invention is a vehicle body side structure having a hinge pillar that constitutes the front peripheral edge of a door opening opened and closed by a front door and extends in the vertical direction. The hinge pillar includes a side body inner panel, a front door hinge reinforcement located outside the side body inner panel in the vehicle width direction, and a side body outer panel located outside the front door hinge reinforcement in the vehicle width direction. The vehicle body side structure has a hinge bracket provided with an attachment surface portion to which a door hinge of the front door is attached. The hinge bracket is fixed to the front door hinge reinforcement such that the attachment surface portion is located outside the front door hinge reinforcement in the vehicle width direction, and the door hinge is configured to be attached to the attachment surface portion from the outside in the vehicle width direction together with the side body outer panel.

Effects of the Invention

[0008] According to one aspect of the present invention, it is possible to provide a vehicle body side structure that can easily cope with an increase in the vehicle width direction for a large vehicle width segment even when using a platform that is commonized for different segments.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing the front side of the vehicle side portion 2 on the right side of the vehicle 1 according to an embodiment of the present invention from the outside, and FIG. 2 is a perspective view showing from the outside the state of the right side portion of the vehicle body of the vehicle 1 excluding the front door 8 to be described later. The vehicle 1 according to the present embodiment includes an engine room (not shown) in which an engine (not shown) is disposed in front of the vehicle 1, and a passenger compartment in which passengers get on and off behind the engine room and a cargo compartment behind the passenger compartment. Hereinafter, in the drawings, the direction of arrow Fr is defined as the front in the front-rear direction of the vehicle 1 (hereinafter referred to as the front-rear direction), the direction of arrow R is defined as the right in the vehicle width direction of the vehicle 1 (hereinafter referred to as the vehicle width direction), and the direction of arrow U is defined as the upper in the up-down direction of the vehicle 1 (hereinafter referred to as the up-down direction). Also, since the vehicle 1 has a symmetric structure, hereinafter, the vehicle side portion 2 on the right side will be described unless otherwise specified. Also, unless otherwise specified, "inside the vehicle width direction" or "inside the vehicle compartment" refers to the inside of the passenger compartment 3, and "outside the vehicle width direction" or "outside the vehicle compartment" refers to the outside of the passenger compartment 3.

[0011] Referring to FIGS. 1 and 2, the vehicle 1 will be described. The vehicle 1 includes a steel vehicle body 4. The vehicle body 4 includes left and right vehicle side portions 2 that constitute the left and right sides of the vehicle body 4, a floor panel 5 that constitutes the vehicle compartment floor surface, and a dash panel 6 that partitions the passenger compartment 3 and an engine room disposed in front of the passenger compartment 3. A door opening 7 for passengers to get on and off is provided in each of the left and right vehicle side portions 2, and the front side of the door opening 7 is opened and closed by a front door 8. The outer periphery of the door opening 7 is constituted by a peripheral edge portion 9, and the peripheral edge portion 9 includes a front peripheral edge portion 10 disposed on the front side of the door opening 7 and a lower peripheral edge portion 11 disposed on the lower side of the door opening 7.

[0012] Further, the vehicle body 4 includes a pair of left and right side sills 15 and a pair of left and right hinge pillars 16 extending upward from the front end portions of the pair of side sills 15. The side sill 15 constitutes the lower peripheral edge portion 11 of the door opening 7, and the hinge pillar 16 constitutes a part of the front peripheral edge portion 10 of the door opening 7. Further, the vehicle body 4 includes a pair of left and right front side members 17 extending forward from the lower part of the dash panel 6 and a pair of left and right cowl side members 18 extending forward from the upper end portions of the pair of hinge pillars 16. The cowl side member 18 has a cowl side member outer 18a disposed on the outer side in the vehicle width direction and a cowl side member inner 18b disposed on the inner side in the vehicle width direction (see FIG. 3). Door hinges 12 for opening and closing the front door 8 are vertically disposed on each of the pair of hinge pillars 16.

[0013] Next, the hinge pillar 16 will be described with reference to FIG. 3. FIG. 3 is a horizontal cross-sectional shape of the hinge pillar 16 viewed from above. The hinge pillar 16 has a side body inner panel 25, a front door hinge reinforcement 26, and a side body outer panel 27. The side body inner panel 25, the front door hinge reinforcement 26, and the side body outer panel 27 are arranged at intervals in the vehicle width direction in the order of the side body inner panel 25, the front door hinge reinforcement 26, and the side body outer panel 27 from the inner side to the outer side in the vehicle width direction. That is, the hinge pillar 16 has a configuration including a side body inner panel 25, a front door hinge reinforcement 26 positioned outside the side body inner panel 25 in the vehicle width direction, and a side body outer panel 27 positioned outside the front door hinge reinforcement 26 in the vehicle width direction.

[0014] The side body inner panel 25 has a flat horizontal cross-section. The front door hinge reinforcement 26 has a convex horizontal cross-section that protrudes outward in the vehicle width direction, and includes a vertical wall portion 26a, front and rear leg portions 26b that extend inward in the vehicle width direction from both ends in the front-rear direction of the vertical wall portion 26a, and front and rear flange portions 26c that bend and extend from the inner ends in the vehicle width direction of the front and rear leg portions 26b to the opposite side of the vertical wall portion 26a. The side body outer panel 27 protrudes outward in the vehicle width direction and has a convex horizontal cross-section that protrudes outward in the vehicle width direction, but does not have a front flange portion. In the perspective view shown in FIG. 2, in order to explain the front door hinge reinforcement 26, a state in which the side body outer panel 27 is removed is shown.

[0015] As shown in FIG. 3, the front and rear flange portions 26c of the front door hinge reinforcement 26 located on the outer side in the vehicle width direction are spot-welded to the side body inner panel 25 located on the inner side in the vehicle width direction, so that the side body inner panel 25 and the front door hinge reinforcement 26 are integrally formed, and the hinge pillar 16 forms a closed cross-section extending in the vertical direction. The cowl side member inner 18b is joined by being spot-welded to the side body inner panel 25 together with the front flange portion 26c of the front door hinge reinforcement 26. Since the front door hinge reinforcement 26 is a member to which a door hinge 12 for opening and closing the front door 8 is attached via a hinge bracket 30 described later, it is a member that requires strength. Therefore, the material of the front door hinge reinforcement 26 is high-tensile steel (high-tensile material), and the plate thickness is 1.4 mm. Note that the material of the front door hinge reinforcement 26 may be ultra-high-tensile steel.

[0016] Next, with reference to FIGS. 2 to 5, a hinge bracket 30 to which a door hinge 12 of a front door (not shown) is attached will be described. FIG. 4 is an enlarged side view showing a vehicle side portion 2 on the right side of the vehicle 1 according to the present embodiment. FIG. 5 is an enlarged side view showing a state in which a cowl side member outer 18a in the enlarged side view of FIG. 4 is removed. The hinge bracket 30 has an attachment surface portion 31 to which the door hinge 12 for opening and closing the front door 8 is attached. As shown in FIG. 3, the hinge bracket 30 is disposed between the front door hinge reinforcement 26 and the side body outer panel 27 in the vehicle width direction, and the attachment surface portion 31 is disposed outside the vehicle width direction with respect to the vertical wall portion 26a of the front door hinge reinforcement 26. More specifically, the attachment surface portion 31 is fixed to the front door hinge reinforcement 26 so as to be disposed outside the vehicle width direction with respect to the vertical wall portion 26a with a predetermined interval therebetween.

[0017] Generally, the vehicle width varies for each segment. However, in order to make the platform common for different segments, the platform is designed based on the segment with a smaller vehicle width. Therefore, in order to accommodate the segment with a larger vehicle width, the increase in the vehicle width direction needs to be addressed on the hinge pillar 16 side including the front door hinge reinforcement 26. However, since the front door hinge reinforcement 26 is made of high-tensile steel, it is difficult to easily address the increase in the vehicle width direction with the front door hinge reinforcement 26 because the difficulty of formability increases. On the other hand, although it is conceivable to change the platform for each different segment, the platform cannot be made common and the cost increases. Therefore, in the present embodiment, in order to accommodate the segment with a larger vehicle width and eliminate the need to address the increase in the vehicle width direction with the front door hinge reinforcement 26, the hinge bracket 30 is fixed to the front door hinge reinforcement 26 such that the attachment surface portion 31 to which the door hinge 12 is attached is located outside the vehicle width direction compared to the front door hinge reinforcement 26. Thereby, even when using a common platform for different segments, a vehicle body side structure can be provided that can easily address the increase in the vehicle width direction for the segment with a larger vehicle width.

[0018] Next, with reference to FIGS. 6 and 7, the structure of the hinge bracket 30 will be described. FIG. 6 is a perspective view of the hinge bracket 30 when viewed from the front side on the outside in the vehicle width direction. FIG. 7 is a three-view drawing of the hinge bracket 30, where (a) is a front view when viewed from the outside in the vehicle width direction, (b) is a bottom view thereof, and (c) is a front view thereof. Note that the directions in FIGS. 6 and 7 represent the directions when the hinge bracket 30 is fixed to the front door hinge reinforcement 26.

[0019] The hinge bracket 30 has a flat plate-shaped attachment surface portion 31 to which the door hinge 12 is attached, a cylindrical peripheral wall portion 33 having one end connected to the periphery 32 of the attachment surface portion 31, and a joint portion 34 connected to the other end of the peripheral wall portion 33 and joined to the front door hinge reinforcement 26.

[0020] The peripheral wall portion 33 is inclined so as to spread from the peripheral edge 32 of the mounting surface portion 31 as it extends from one end connected to the peripheral edge 32 of the mounting surface portion 31 toward the other end. The peripheral wall portion 33 includes a flat front peripheral wall portion 33a disposed on the front side of the mounting surface portion 31, a flat rear peripheral wall portion 33b disposed on the rear side of the mounting surface portion 31, a flat upper peripheral wall portion 33c disposed above the mounting surface portion 31 and connected to the front peripheral wall portion 33a and the rear peripheral wall portion 33b, and a flat lower peripheral wall portion 33d disposed below the mounting surface portion 31 and connected to the front peripheral wall portion 33a and the rear peripheral wall portion 33b in a state where the hinge bracket 30 is fixed to the front door hinge reinforcement 26.

[0021] The joint portion 34 includes a front joint portion 34a connected to the other end of the front peripheral wall portion 33a and joined to the front leg portion 26b of the front door hinge reinforcement 26, a rear joint portion 34b connected to the other end of the rear peripheral wall portion 33b and joined to the rear leg portion 26b of the front door hinge reinforcement 26, an upper joint portion 34c connected to the other end of the upper peripheral wall portion 33c and joined to the vertical wall portion 26a of the front door hinge reinforcement 26, and a lower joint portion 34d connected to the lower peripheral wall portion 33d and joined to the vertical wall portion 26a of the front door hinge reinforcement 26.

[0022] As shown in FIGS. 3 and 5, in a state where the hinge bracket 30 is fixed to the front door hinge reinforcement 26, the mounting surface portion 31 is located outside the peripheral wall portion 33 in the vehicle width direction, and the peripheral wall portion 33 extends from the mounting surface portion 31 toward the front door hinge reinforcement 26 and is formed in a convex shape on the outside in the vehicle width direction. The peripheral wall portion 33 is inclined so as to spread from the peripheral edge 32 of the mounting surface portion 31 as it extends from the mounting surface portion 31 toward the front door hinge reinforcement 26.

[0023] The material of the hinge bracket 30 is high-tensile steel (Hi-Ten material), and the plate thickness is 1.8 mm. Incidentally, the material of the hinge bracket 30 may be ultra-high-tensile steel. The hinge bracket 30 is formed by press-molding a high-tensile steel plate material so that the mounting surface portion 31, the peripheral wall portion 33, and the joint portion 34 are integrated. Therefore, the mounting surface portion 31, the front peripheral wall portion 33a, the rear peripheral wall portion 33b, the upper peripheral wall portion 33c, the lower peripheral wall portion 33d, the front joint portion 34a, the rear joint portion 34b, the upper joint portion 34c, and the lower joint portion 34d are integrated. The hinge bracket 30 has a ridge line 35 formed by connecting the respective members of the mounting surface portion 31, the front peripheral wall portion 33a, the rear peripheral wall portion 33b, the upper peripheral wall portion 33c, and the lower peripheral wall portion 33d. The ridge line 35 includes at least a ridge line formed by the mounting surface portion 31 and the peripheral wall portion 33 and a ridge line formed by the peripheral wall portions 33a to 33d.

[0024] On the front peripheral wall portion 33a, at the center in the vertical direction, a convex portion 36 is provided which is formed to protrude outward in the vehicle direction from one end connected to the periphery 32 of the mounting surface portion 31 to the other end. As shown in FIG. 4, the rear end side of the cowl side member outer 18a is connected to the front peripheral wall portion 33a. The vertical width of the rear end side of the cowl side member outer 18a is substantially the same as the vertical width of the front peripheral wall portion 33a and is within the vertical width of the front peripheral wall portion 33a. Further, the rear end side of the cowl side member outer 18a is formed along the shape of the front peripheral wall portion 33a, and a rear end side convex portion 18c formed to protrude outward in the vehicle direction is provided on the rear end side of the cowl side member outer 18a.

[0025] As shown in FIGS. 5 to 7, two first through-holes 37 for fixing the rear end side of the cowl side member outer 18a are provided side by side in the vertical direction on the front peripheral wall portion 33a. Of the two first through-holes 37, the upper first through-hole 37 is disposed at a position closer to the upper peripheral wall portion 33c side. That is, the upper first through-hole 37 is disposed adjacent to the ridge line 35 formed by the connection of the front peripheral wall portion 33a and the upper peripheral wall portion 33c. Further, the lower first through-hole 37 is disposed at a position closer to the lower peripheral wall portion 33d side. That is, the lower first through-hole 37 is disposed adjacent to the ridge line 35 formed by the connection of the front peripheral wall portion 33a and the lower peripheral wall portion 33d. A through-hole (not shown) corresponding to the two first through-holes 37 is formed in the rear end side of the cowl side member outer 18a, and the rear end side of the cowl side member outer 18a is fixed to the front peripheral wall portion 33a by bolts and nuts passed through the through-hole and the two first through-holes 37. Incidentally, the two first through-holes 37 are connection points between the front peripheral wall portion provided on the front peripheral wall portion in the present invention and the cowl side member outer.

[0026] The cowl side member 18 is a member that supports the load when the vehicle 1 collides forward, and the load (collision load) is received by the front peripheral wall portion 33a via the cowl side member 18. However, since the convex portion 36 is provided on the front peripheral wall portion 33a, deformation of the front peripheral wall portion 33a due to the collision load is suppressed. Further, since the vertical width of the rear end side of the cowl side member outer 18a is substantially the same as the vertical width of the front peripheral wall portion 33a, the collision load received by the front peripheral wall portion 33a via the cowl side member 18 is transmitted to each of the upper peripheral wall portion 33c and the lower peripheral wall portion 33d, and the upper peripheral wall portion 33c and the lower peripheral wall portion 33d receive the collision load, thereby suppressing deformation of the hinge bracket 30. Further, each of the two first through-holes 37 is disposed adjacent to each of the upper peripheral wall portion 33c and the lower peripheral wall portion 33d. Therefore, the collision load received by the front peripheral wall portion 33a via the cowl side member 18 is transmitted to each of the upper peripheral wall portion 33c and the lower peripheral wall portion 33d, and the upper peripheral wall portion 33c and the lower peripheral wall portion 33d receive the impact load, thereby suppressing deformation of the hinge bracket 30.

[0027] On the mounting surface portion 31, two second through holes 38 for fixing the door hinge 12 are provided side by side in the horizontal direction. As shown in FIG. 3, the door hinge 12 is attached by being bolted together with the side body outer panel 27 to the mounting surface portion 31 of the hinge bracket 30 from the outside in the vehicle width direction. Incidentally, in a state where the hinge bracket 30 is fixed to the front door hinge reinforcement 26, since the inside of the hinge bracket 30 is not accessible to the operator's hand, a female screw-formed part or a nut is welded and fixed to the inside of the mounting surface portion 31 as shown in FIG. 3.

[0028] Next, with reference to FIGS. 3 and 5, the structure in which the hinge bracket 30 is fixed to the front door hinge reinforcement 26 will be described. The hinge bracket 30 is disposed between the front door hinge reinforcement 26 and the side body outer panel 27 in the vehicle width direction, and the mounting surface portion 31 is disposed outside the longitudinal wall portion 26a of the front door hinge reinforcement 26 in the vehicle width direction. The hinge bracket 30 is fixed to the front door hinge reinforcement 26 by joining the front joining portion 34a connected to the other end of the front peripheral wall portion 33a to the front leg portion 26b of the front door hinge reinforcement 26, joining the rear joining portion 34b connected to the other end of the rear peripheral wall portion 33b to the rear leg portion 26b of the front door hinge reinforcement 26, joining the upper joining portion 34c connected to the other end of the upper peripheral wall portion 33c to the longitudinal wall portion 26a of the front door hinge reinforcement 26, and joining the lower joining portion 34d connected to the other end of the lower peripheral wall portion 33d to the longitudinal wall portion 26a of the front door hinge reinforcement 26.

[0029] When the hinge bracket 30 is fixed to the front door hinge reinforcement 26, since the front joint portion 34a connected to the other end of the front peripheral wall portion 33a is joined to the front leg portion 26b of the front door hinge reinforcement 26, the other end of the front peripheral wall portion 33a is located at the connection portion between the vertical wall portion 26a, which is the front edge of the vertical wall portion 26a of the front door hinge reinforcement 26, and the front leg portion 26b. Also, since the rear joint portion 34b connected to the other end of the rear peripheral wall portion 33b is joined to the rear leg portion 26b of the front door hinge reinforcement 26, the other end of the rear peripheral wall portion 33b is located at the connection portion between the vertical wall portion 26a, which is the rear edge of the vertical wall portion 26a of the front door hinge reinforcement 26, and the rear leg portion 26b. Therefore, the other ends of the upper peripheral wall portion 33c and the lower peripheral wall portion 33d extend from the front edge to the rear edge of the vertical wall portion 26a of the front door hinge reinforcement 26. That is, the ridge line 35 formed by the front peripheral wall portion 33a and the upper peripheral wall portion 33c and the ridge line 35 formed by the front peripheral wall portion 33a and the lower peripheral wall portion 33d extend to the connection portion between the vertical wall portion 26a, which is the front edge of the vertical wall portion 26a, and the front leg portion 26b. Also, the ridge line 35 formed by the rear peripheral wall portion 33b and the upper peripheral wall portion 33c and the ridge line 35 formed by the rear peripheral wall portion 33b and the lower peripheral wall portion 33d extend to the connection portion between the vertical wall portion 26a, which is the rear edge of the vertical wall portion 26a, and the rear leg portion 26b.

[0030] Thus, the other end of the front peripheral wall portion 33a is located at the connection portion between the vertical wall portion 26a, which is the front edge of the vertical wall portion 26a of the front door hinge reinforcement 26, and the front leg portion 26b. Also, the other end of the rear peripheral wall portion 33b is located at the connection portion between the vertical wall portion 26a, which is the rear edge of the vertical wall portion 26a of the front door hinge reinforcement 26, and the rear leg portion 26b. Therefore, since the load received by the door hinge 12 is received by the front and rear leg portions 26b of the front door hinge reinforcement 26, deformation of the front door hinge reinforcement 26 can be suppressed by the load received by the door hinge 12. That is, the ridge line 35 formed by the front peripheral wall portion 33a and the upper peripheral wall portion 33c and the ridge line 35 formed by the front peripheral wall portion 33a and the lower peripheral wall portion 33d extend to the connection portion between the vertical wall portion 26a, which is the front edge of the vertical wall portion 26a, and the front leg portion 26b. Also, the ridge line 35 formed by the rear peripheral wall portion 33b and the upper peripheral wall portion 33c and the ridge line 35 formed by the rear peripheral wall portion 33b and the lower peripheral wall portion 33d extend to the connection portion between the vertical wall portion 26a, which is the rear edge of the vertical wall portion 26a, and the rear leg portion 26b. Therefore, deformation of the front door hinge reinforcement 26 can be suppressed by the load received by the door hinge 12.

[0031] In the present embodiment, in a state where the hinge bracket 30 is fixed to the front door hinge reinforcement 26, the hinge bracket 30 has an attachment surface portion 31 to which the door hinge 12 is attached, and a cylindrical peripheral wall portion 33 having one end connected to the peripheral edge 32 of the attachment surface portion 31 and extending toward the front door hinge reinforcement 26, and is formed in a convex shape toward the outside in the vehicle width direction. The peripheral wall portion 33 is inclined so as to expand from the peripheral edge 32 of the attachment surface portion 31 as it goes from the attachment surface portion 31 toward the front door hinge reinforcement 26. With this configuration, the hinge bracket 30 supports the load from the door hinge 12, but deformation of the hinge bracket 30 due to the load from the door hinge 12 can be suppressed.

[0032] As described above, some embodiments of the present invention have been described. It should be added that the present invention is not limited to the above embodiments, and various modifications and changes are possible within the scope of the present invention.

[0033] For example, in the present embodiment, the peripheral wall portion 33 of the hinge bracket 30 includes a flat front peripheral wall portion 33a disposed on the front side of the mounting surface portion 31, a flat rear peripheral wall portion 33b disposed on the rear side of the mounting surface portion 31, a flat upper peripheral wall portion 33c disposed on the upper side of the mounting surface portion 31 and connected to the front peripheral wall portion 33a and the rear peripheral wall portion 33b, and a flat lower peripheral wall portion 33d disposed on the lower side of the mounting surface portion 31 and connected to the front peripheral wall portion 33a and the rear peripheral wall portion 33b. However, it is not necessarily limited to this. As long as the peripheral wall portion 33 is configured to incline so as to expand from the peripheral edge 32 of the mounting surface portion 31 as it extends from one end connected to the peripheral edge 32 of the mounting surface portion 31 to the other end, each of the front peripheral wall portion 33a, the rear peripheral wall portion 33b, the upper peripheral wall portion 33c, and the lower peripheral wall portion 33d may be formed in a curved surface shape instead of a flat plate shape. Further, the peripheral wall portion 33 of the present embodiment is composed of four peripheral wall portions, namely, the front peripheral wall portion 33a, the rear peripheral wall portion 33b, the upper peripheral wall portion 33c, and the lower peripheral wall portion 33d. However, it is not necessarily limited to this. As long as the peripheral wall portion 33 is configured to incline so as to expand from the peripheral edge 32 of the mounting surface portion 31 as it extends from one end connected to the peripheral edge 32 of the mounting surface portion 31 to the other end, the peripheral wall portion 33 may be composed of three flat plate-shaped peripheral wall portions or five or more flat plate-shaped peripheral wall portions.
