And the glass frame 20 guides the raising / lowering of the door glass 18 by the raising / lowering apparatus (illustration omitted) arrange | positioned inside the side door 10 for vehicles.

  The door inner panel 16 is formed of a substantially rectangular plate material, and is a substantially flat general portion (flat portion) 16B disposed at the center in the vehicle vertical direction (a portion excluding the vicinity of the end edge portion 16A). And a wall portion 16D bent outward from the peripheral edge portion 16C of the general portion 16B in the vehicle width direction. That is, the peripheral edge portion 16 </ b> C is a ridge line between the substantially planar general portion 16 </ b> B and the wall portion 16 </ b> D of the door inner panel 16.

  As shown in FIGS. 2 to 5, the door inner panel 16 has a substantially triangular shape in a vehicle side view by locally bending the plate material of the door inner panel 16 toward the door outer panel 14 in the plate thickness direction. The seating surface 30 is formed. When viewed from the side of the vehicle, the seat surface 30 is formed of a substantially isosceles triangle, the apex angle 30B sandwiched between the two sides 30A having the same length is disposed on the vehicle front side, and the base 30C facing the apex angle 30B is the vehicle rear side. (Refer to FIG. 4). In other words, the seat surface 30 of the “substantially isosceles triangle” of the present embodiment is not limited to the corner portion (vertical angle 30B or base angle 30D) of the seat surface 30, but the corner portion of the seat surface 30. A shape in which (vertical angle 30B or base angle 30D) is curved in an R shape is also included.

  A substantially circular fastening surface 32 is formed in the center of the seat surface 30 of the door inner panel 16 in a side view of the vehicle. The fastening surface 32 is formed in a substantially planar shape along the vehicle vertical direction, and an attachment hole 32A is formed at the center of the fastening surface 32 (see FIG. 5). Then, a bolt 34 is inserted from the vehicle width direction inner side of the mounting hole 32A of the fastening surface 32, and a nut 36 is screwed to the bolt 34, whereby the bracket 38 is fastened and fixed to the fastening surface 32 (see FIG. 3). ). A washer 37 is interposed between the bolt 34 and the fastening surface 32.

  The bracket 38 is bent from the rear end of the mounting surface 38A obliquely outward in the vehicle width direction to the mounting surface 38A disposed in surface contact with the fastening surface 32 when viewed in the vehicle vertical direction (in plan view of the vehicle). An intermediate portion 38B, and an outer wall portion 38C bent substantially outward in the vehicle width direction from the rear end of the intermediate portion 38B. The glass frame 20 is joined to the front surface of the outer side wall portion 38C by welding or the like.

  In the present embodiment, the seat surface 30 and the fastening surface 32 of the door inner panel 16 and the bracket 38 are provided on the glass frame 20 on the vehicle rear side as viewed from the side of the vehicle.

As shown in FIG. 10, when the vehicle side door 10 is closed with the door glass 18 fully opened, the inertia force F ₀ of the door glass 18 acts in the vehicle inner direction. Since the bracket 38 includes an intermediate portion 38B bent from the rear end of the mounting surface 38A to the diagonally rearward outside in the vehicle width direction, the bracket 38 is fastened and fastened to the fastening surface 32 by the bolt 34 and the nut 36. The part is offset by a distance L with respect to the force acting from the glass frame 20. Therefore, the bending moment M resulting from the offset by the distance L with respect to the input point acts on the fastening portion, and the bracket 38 falls to the vehicle rear side as indicated by the arrow B. For this reason, stress may concentrate on the peripheral edge 30E of the seating surface 30 of the door inner panel 16 on the side where the bracket 38 is offset, particularly the peripheral edge 30E of the seating surface 30 on the vehicle rear side as viewed from the fastening surface 32. There is.

  For example, as shown in FIG. 11, in the glass frame fastening portion structure 100 shown in the first comparative example, the door inner panel 102 is locally bent toward the glass frame 20 (see FIG. 10) in a vehicle side view. A circular seating surface 104 and a circular fastening surface 106 to which a bracket 38 (see FIG. 10) is fastened and fixed in the seating surface 104 are provided. In the glass frame fastening portion structure 100, when the vehicle side door is closed, the vehicle rear side of the peripheral edge portion 104A of the seat surface 104 of the door inner panel 102 on the side where the bracket 38 is offset, in particular, gravity Due to the influence, there is a possibility that stress concentrates at the lower rear portion 104B of the vehicle.

  12, in the glass frame fastening part structure 110 shown in the second comparative example, the door inner panel 112 is locally bent toward the glass frame 20 (see FIG. 10) in a vehicle side view. A substantially triangular seat surface 114 and a substantially triangular fastening surface 116 to which the bracket 38 (see FIG. 10) is fastened and fixed in the seat surface 114 are provided. The fastening surface 116 is formed in a substantially triangular shape that is slightly smaller than the seating surface 114, and the corner portion is curved in an R shape. In the glass frame fastening part structure 110, when the vehicle side door is closed, the shape of the R is a sudden change part at the peripheral edge 114A of the seating surface 114 of the door inner panel 112 on the side where the bracket 38 is offset. There is a possibility of stress concentration near the corner 114B.

  Further, in the glass frame fastening part structure 110, when the substantially triangular fastening surface 116 is provided, it is necessary to widen the fastening surface 116 in order to secure a plane on which the washer 37 abuts, and the surface rigidity of the fastening surface 116 is reduced. there's a possibility that.

  As shown in FIG. 4 and the like, in the glass frame fastening part structure 12 of the present embodiment, the seat surface 30 is formed of a substantially isosceles triangle as described above, and the apex angle 30B and the base angle 30D (corner part) are R-shaped. It is formed to be curved. Further, the base 30C facing the apex angle 30B is formed longer than the two sides 30A having the same length forming the apex angle 30B. Further, the apex angle 30B is preferably, for example, 80 degrees or more, and more preferably 90 degrees or more. Further, the upper limit value of the apex angle 30 </ b> B may be in a range where the fastening surface 32 can be formed on the seat surface 30. In the present embodiment, the apex angle 30B is, for example, preferably 120 degrees or less, and more preferably 110 degrees or less.

  As shown in FIG. 6A, when the angle of the apex angle 30B of the seating surface 30 is large, as shown in FIG. 6B, compared to the case where the angle of the apex angle 200B of the seating surface 200 is small. The base 30C facing the apex angle 30B is longer than the two sides 30A having the same length forming the apex angle 30B. That is, the base 30C of the seating surface 30 shown in FIG. 6 (A) is longer than the base 200C of the seating surface 200 shown in FIG. 6 (B). This makes it possible to move the base angle 30D of the seating surface 30 away from the load point at which the bracket 38 (see FIG. 3) is fastened and fixed to the fastening surface 32, and stress is concentrated near the base angle 30D of the seating surface 30. Can be suppressed.

  4 and the like, in the glass frame fastening part structure 12 of the present embodiment, the base 30C of the isosceles triangle on the seating surface 30 of the door inner panel 16 and the peripheral edge of the general part 16B of the door inner panel 16 are used. The portion (ridge line) 16C is arranged so as to be substantially parallel. As shown in FIG. 7B, when the extension line of the bottom side 210C of the seating surface 210 of the door inner panel 16 and the peripheral edge portion 16C of the general portion 16B of the door inner panel 16 are arranged to intersect each other. One base angle 210D of the seat surface 210 is closer to the peripheral edge portion 16C of the general portion 16B of the door inner panel 16 than the other base angle 210D, and stress is concentrated in the vicinity of the one base angle 210D of the seat surface 210. there is a possibility. On the other hand, as shown in FIG. 7A, when the bottom side 200C of the seating surface 200 of the door inner panel 16 and the peripheral edge portion 16C of the general portion 16B of the door inner panel 16 are arranged substantially in parallel. The one bottom angle 210D of the seating surface 200 does not approach the peripheral edge portion 16C, and stress can be prevented from concentrating near the one bottom angle 200D.

  As shown in FIG. 4 and the like, in the glass frame fastening part structure 12 of the present embodiment, the fastening surface 32 of the door inner panel 16 is a round seat having a diameter that is slightly larger than the diameter of the washer 37. That is, the fastening surface 32 is a circle having a necessary minimum size slightly larger than the diameter of the washer 37. For example, as shown in FIG. The diameter is slightly larger than the diameter (the diameter of the washer 37 + about 5 mm). By making the fastening surface 32 of the door inner panel 16 a round seat that is slightly larger than the diameter of the washer 37, for example, the washer 37 abuts against the case where the fastening surface has a substantially triangular shape (see FIG. 12). The fastening surface 32 can be reduced, and the surface rigidity of the fastening surface 32 can be improved.

  Moreover, in the glass frame fastening part structure 12 of this embodiment, it is preferable that the fastening surface 32 of the door inner panel 16 is formed at a position closer to the apex angle 30B than the centroid of the isosceles triangle in the seating surface 30. . In other words, the fastening surface 32 of the door inner panel 16 is arranged close to the apex angle 30B facing the base 30C from the centroid of the seating surface 30, and the distance between the fastening surface 32 and the base 30C is set to the fastening surface 32 and the apex angle 30B. It is preferable to make it longer than the distance. The centroid means the center of gravity of an isosceles triangle (planar figure) on the seating surface 30 in a vehicle side view. For example, as shown in FIG. 8A, when the fastening surface 220 of the door inner panel 16 is formed at a position closer to the apex angle 200B than the centroid of the isosceles triangle on the seating surface 200, FIG. B) As shown in FIG. 5B, the seat surface from the load point that fastens and fixes the bracket 38 to the fastening surface 220 as compared with the case where the fastening surface 222 of the door inner panel 16 is formed at a position far from the apex angle 200B of the seat surface 200. The base angle 200D and the base side 200C of 200 can be moved away. For this reason, it can suppress that stress concentrates on the base angle 200D of the seating surface 200, and base 200C vicinity.

  In the present embodiment, for example, as shown in FIG. 5, when the distance between the centroid of the seating surface 30 of the door inner panel 16 and the bottom side 30 </ b> C of the seating surface 30 is about 18.5 mm, The distance L2 between the center point of the attachment hole 32A of the fastening surface 32 and the bottom side 30C of the seat surface 30 of the door inner panel 16 is preferably set to about 21 mm or less. As a contradiction to increase the distance L2 between the center point of the attachment hole 32A of the fastening surface 32 and the bottom side 30C of the seating surface 30, there is a possibility that distortion at the end of the washer 37 may increase. In FIG. 9, when the distance between the centroid of the seating surface 30 and the base 30 </ b> C of the seating surface 30 is a reference length (18.5 mm), the center point of the mounting hole 32 </ b> A of the fastening surface 32 and the seating surface 30. The relationship between the value obtained by subtracting the reference length from the distance L2 from the base 30C and the strain generated at the end of the washer 37 is shown. As shown in this figure, when the value obtained by subtracting the reference length from the distance L2 between the center point of the mounting hole 32A of the fastening surface 32 and the bottom 30C of the seat surface 30 exceeds 2.5 mm, the seat surface 30 It can be seen that the strain at the end of the washer 37 is larger than the strain at the bottom 30C portion. For this reason, it is preferable to set the distance L2 between the center point of the mounting hole 32A of the fastening surface 32 of the door inner panel 16 and the base 30C of the seat surface 30 of the door inner panel 16 to about 21 mm or less.

  Next, the operation and effect of this embodiment will be described.

  As shown in FIG. 3 and FIG. 4 and the like, the door inner panel 16 has a substantially isosceles triangular seating surface 30 in a vehicle side view so as to be convex toward the bracket 38 side for fixing the glass frame 20. In addition to being formed, a substantially circular fastening surface 32 is formed on the seat surface 30 in a side view of the vehicle. The mounting surface 38A of the bracket 38 is fastened and fixed to the fastening surface 32 by bolts 34 and nuts 36, so that the glass frame 20 is fixed to the fastening surface 32 of the door inner panel 16 via the bracket 38. . By providing the door inner panel 16 with a substantially triangular seat surface 30 and a substantially circular fastening surface 32, the edge of the fastening surface 32 and the base angle 30D of the seat surface 30 where stress tends to concentrate ((the bottom 30C The sharp corners on both sides) can be separated from each other, and stress concentration in the vicinity of the base angle 30D of the seating surface 30 can be reduced.

  In addition, the seat surface 30 is a substantially isosceles triangle as viewed from the side of the vehicle, and a base 30C facing the apex angle 30B of the substantially isosceles triangle is formed longer than the other two sides 30A. Accordingly, the length of the base 30C is made sufficiently longer than the other two sides 30A, and the base angle 30D of the seating surface 30 (the acute angle portions on both sides of the base 30C) is fastened to the fastening surface 32 (load) It is possible to reduce the concentration of stress on the base angle 30D portion of the substantially isosceles triangle on the seating surface 30.

  In the present embodiment, the apex angle 30B of the seating surface 30 of the door inner panel 16 is 80 degrees or more. Thereby, the length of the base 30C facing the apex angle 30B of the seating surface 30 can be made sufficiently long, and the concentration of stress on the base angle 30D portion of the seating surface 30 can be further reduced.

Thereby, it can avoid that one of the base angles 30D of the substantially isosceles triangle in the seat surface 30 approaches the peripheral part 16C of the general part 16B of the door inner panel 16 from the other of the base angles 30D. For this reason, it is possible to reduce the local concentration of stress on one base angle 30D portion of the seating surface 30 or the bottom side 30C of the seating surface 30.

  The fastening surface 32 of the door inner panel 16 is a round seat having a diameter that is slightly larger than the diameter of the washer 37. Accordingly, for example, the fastening surface 32 can be made smaller than when the fastening surface 116 has a substantially triangular shape slightly smaller than the seating surface 30 (see FIG. 12), and the surface rigidity of the fastening surface 32 is improved. be able to.

  Further, the fastening surface 32 of the door inner panel 16 may be formed at a position closer to the apex angle 30 </ b> B than the centroid of the isosceles triangle on the seat surface 30. Thereby, the base 30C of the seating surface 30 can be moved away from the fastening surface 32 (loading point) to which the bracket 38 is fastened and fixed, and locally on the bottom angle 30D portion of the seating surface 30 or the base 30C of the seating surface 30. The concentration of stress can be reduced.

  In the above-described embodiment, the apex angle 30B and the base angle 30D of the seat surface 30 made of a substantially isosceles triangle are curved in an R shape, but the apex angle 30B and the base angle 30D are formed in this shape. It is not limited, It is good also as changing the curvature of an R-shaped curved part, or making it the shape close | similar to a cusp.

  Moreover, in the said embodiment, although the seat surface 30 is a substantially isosceles triangle, it is not limited to this, It is good also as a substantially triangular seat surface. That is, the “triangle” and “isosceles triangle” of the present invention include those in which corners (vertical angle, base angle, etc.) are curved in an R shape within a range where the effect is obtained.

  Moreover, in the said embodiment, although it has arrange | positioned so that the base 30C of the seat surface 30 of the door inner panel 16 and the peripheral part 16C of the general part 16B of the door inner panel 16 may become substantially parallel, it is completely parallel. It does not have to be. For example, with respect to the peripheral portion 16C of the general portion 16B of the door inner panel 16 as long as stress can be prevented from locally concentrating in the vicinity of the base 30C and the base angle 30D of the seat surface 30 of the door inner panel 16. The base 30 </ b> C of the seating surface 30 of the door inner panel 16 may be inclined. For example, the angle between the extension line of the bottom 30C of the seat surface 30 and the peripheral edge 16C of the general portion 16B of the door inner panel 16 is preferably set to 10 degrees or less. That is, in the “parallel” of the present invention, the base 30C of the seat surface 30 of the door inner panel 16 is inclined with respect to the peripheral edge 16C of the general portion 16B of the door inner panel 16 within a range where the effect is obtained. Is also included.

  Moreover, in the said embodiment, although the fastening surface 32 is circular shape, it is not limited to this, For example, it is good also as a shape which made one part noncircular, an ellipse, an ellipse, a regular polygon more than a pentagon, etc. . That is, the “circular shape” of the present invention includes a non-circular shape as long as the effect is obtained.
