As Fig. 8, shown in Figure 9, for connecting part main body 35, link main body diapire 71 and inside and outside binding main body wall 72,74 and form roughly コ word shape of cross section.In addition, for leading section 36, preceding binding diapire 77, preceding madial wall rake 93 and preceding lateral wall rake 95 form roughly コ word shape of cross section.And for rearward end 37, the back links diapire 78, back madial wall rake 94 and back lateral wall rake 96 and forms roughly コ word shape of cross section.
Like this, connecting part main body 35, leading section 36 and rearward end 37 form the cross section respectively roughly " コ " the word shape.
Thus, for left connecting part 34, by binding diapire 34a shown in Figure 11, interior binding sidewall 34b and link sidewall 34c outward and form コ word shape cross-section.
By left connecting part 34 being constituted コ word shape cross-section, can further improve the rigidity (intensity) of left connecting part 34.
Right connecting part 34 is and left connecting part 34 symmetrical parts, following detailed.
As described above, by about connecting part 34 (right connecting part 34 with reference to Fig. 4) the first roof track 32 and the second roof track, 33 one are linked (roughly well type), and, thereby with about the rigidity (intensity) of the connecting part 34 of connecting part 34 about making コ word shape cross-section and improving.
Thus, can make the load (shock load) that inputs to roof track in the first roof track 32 and the second roof track 33, a side via about connecting part 34 be dispersed to the opposing party's roof track well.
That is, can utilize roof track in the first roof track 32 and the second roof track 33, the opposing party to support a side roof track.
Particularly, can make the load that inputs to the first roof track 32 via about connecting part 34 be dispersed to the second roof track 33 well.In addition, can make the load that inputs to the second roof track 33 via about connecting part 34 be dispersed to the first roof track 32 well.
That is, can utilize the second roof track 33 and via about 34 pairs of first roof tracks 32 of connecting part support.In addition, can utilize the first roof track 32 and via about 34 pairs of second roof tracks 33 of connecting part support.
Thus, thus can by about connecting part 34 guarantee that fully the rigidity of the first roof track 32 and the second roof track 33 improves the rigidity (intensity) of roof track element 31 (that is, body construction 12).
Therefore, the space of car chamber 13 shown in Figure 2 be can guarantee, and vibration suppression (vibrationproof), noise suppression (soundproof) guaranteed.
And as shown in Figure 2, the connecting part 34 about first skeleton portion 42 and second skeleton portion 45 are passed through links.Thus, can make the load that inputs to skeleton portion in first skeleton portion 42 and second skeleton portion 45, a side via about connecting part 34 be dispersed to the opposing party's skeleton portion.
That is, the skeleton portion that can utilize the opposing party supports a side's of first skeleton portion 42 and second skeleton portion 45 skeleton portion.
Thus, thus can guarantee fully that the rigidity of first skeleton portion 42 and second skeleton portion 45 improves rigidity, the particularly rigidity on top, vehicle body the place ahead (intensity) of body construction 12.
In addition, as shown in Figure 4, by about connecting part 34 link the first roof track 32 and the second roof track 33 integratedly, thus, by the first roof track 32, the second roof track 33 and about connecting part 34 form the roughly roof track element 31 of well type.
Thus, by utilizing the roof siding track 28 about the working fastening anchor clamps are temporarily fixed on roof track element 31, the roof siding track 28 about first, second roof track 32,33 can being temporarily fixed on by working fastening anchor clamps.
That is, needn't use roof siding track 28 about independent working fastening anchor clamps are temporarily fixed on first track 32 and second track 33 respectively.
Thus, the number of employed working fastening anchor clamps is reduced to one from two in the time of can be with the roof siding track 28 about first, second roof track 32,33 is assembled in.
By reducing the number of working fastening anchor clamps, can improve assembling operation during roof siding track 28 about first, second roof track 32,33 is assembled in.
And, by roof track element 31 being formed integrally as roughly well type, can further improve the rigidity (shape stability) of roof track element 31.
Thus, the operability (processing) during roof siding track 28 about roof track element 31 is assembled in is easier, can further improve assembling operation.
As Figure 10, shown in Figure 12, on left connecting part 34, possess aforesaid yielding 85 at leading section 36.
Possess peristome 86 and bight 87 for yielding 85, bight 87 and peristome 86 are disposed in overall width direction (arrow A direction) and go up position overlapped.
Like this, owing to possess yielding 85 at the leading section 36 of left connecting part 34, near yielding 85 distortion permission portion 101 (with reference to Figure 10) forms with the mode that the rigid portion 38 of left connecting part 34 is compared with easy deformation.
For the 77a of diapire position, be in the preceding binding diapire 77, first diapire 51 and preceding binding diapire 77 link, and inside and outside sidewall slope portion 93,95 position before being positioned at.
This peristome 86, in detail, so that 86b and the mode that gently tilts to vehicle body the place ahead tilt with tiltangle with respect to overall width direction (arrow A direction) outward from inner 86a.
Like this, only by peristome 86 is formed in the mode of extending towards the overall width direction, just can form yielding 85 simply.
And the length dimension L of the peristome 86 that extends towards the overall width direction by change just can change yielding 85 rigidity simply.By changing yielding 85 rigidity, can adjust yielding 85 deformation state (deformation pattern).
Thus, when object bumped from vehicle body the place ahead and anterior wind glass 15, the first roof track 32 etc., near the distortion permission portion 101 (with reference to Figure 10) can making yielding 85 was out of shape as starting point reliably with yielding 85.
Here, inside and outside binding sidewall 34b, 34c extend along the vehicle body fore-and-aft direction.Thus, make under inside and outside binding sidewall 34b, 34c and the situation that first rear wall 54 of the first roof track 32 directly is communicated with, inside and outside binding sidewall 34b, 34c and the binding bight (bight) of the first roof track 32, be elbows, become the position that is difficult for deforming with respect to load (shock load) F1 from vehicle body the place ahead.
Therefore, make first rear wall 54 and inside and outside binding main body wall 72,74 be folded with bight 87, bight 87 is used as a part of yielding 85.
Particularly, bight 87 has: the inside and outside rear wall rake (rear wall rake) 91,92 that first rear wall 54 possesses; The preceding madial wall rake (sidewall slope portion) 93 that interior binding main body wall 72 possesses; The preceding lateral wall rake (sidewall slope portion) 95 that outer binding main body wall 74 possesses.
Inside and outside rear wall rake 91, the 92nd, make the position corresponding with inside and outside binding sidewall 34b, 34c (with reference to Figure 11) in first rear wall 54 to the vehicle body rear side with the position near the mode bending ground inclination of the kernel of section 98 of コ word shape cross-section (connecting part) 34.
Before madial wall rake 93 are modes linking with interior rear wall rake 91, from the front end 72b of interior binding main body wall 72 to vehicle body the place ahead and to from kernel of section 98 away from the position that tilts of a lateral bending curvedly.
Before lateral wall rake 95 are modes linking with outer rear wall rake 92, from the front end 74b of outer binding main body wall 74 to vehicle body the place ahead and to from kernel of section 98 away from the position that tilts of a lateral bending curvedly.
Thus, for bight 87, to tilt to the mode bending ground that first rear wall 54 in vehicle body the place ahead is gently expanded from front end 72b and front end 74b.
Thus, bight 87 forms with respect to the shape from the shock load F1 easy deformation of vehicle body the place ahead, vehicle body front upper place.
Like this, the leading section 36 at left connecting part 34 possesses peristome 86 and bight 87 as yielding 85.
Thus, when object bumps from the anterior wind glass 15 (with reference to Fig. 1) of vehicle body the place ahead and vehicle 10, the first roof track 32 etc., thereby near the distortion permission portion 101 can making yielding 85 is out of shape well as starting point with yielding 85 and absorbs impulsive force F 1.
Thus, thus the impulsive force F1 that can suppress to give object improves the protective value of object (for example, pedestrian).
Particularly, bight 87 tilts in the mode of gently expansion to vehicle body the place ahead, thus, forms with respect to the shape from shock load F 1 easy deformation of vehicle body the place ahead, vehicle body front upper place.
Thus, when object bumps from vehicle body the place ahead and anterior wind glass 15 (with reference to Fig. 1), first roof track 32 etc., bight 87 is out of shape well, thus further the improve object protective value of (for example, pedestrian).
And bight 87 and peristome 86 are disposed in overall width direction (arrow A direction) and go up position overlapped.
Thus, when object from vehicle body the place ahead and anterior wind glass 15 (with reference to Fig. 1) thereby, the first roof track 32 etc. bumps from vehicle body the place ahead, during vehicle body front upper place input shock load F1, can utilize the shock load F 1 of input that bight 87 and peristome 86 are out of shape simultaneously.
Thus, can utilize near the shock load F1 of the input distortion permission portion 101 making yielding 85 is that starting point well is out of shape (reliably) with yielding 85.
Like this, making distortion permission portion 101 is that starting point is out of shape well with yielding 85, can further improve object (for example, pedestrian's) protective value thus.
In addition, possess reinforced rib 83 between the leading section 36 in the binding main body diapire 71 of left connecting part 34 and the rearward end 37, thus, reinforced rib 83 is compared with yielding 85 and is arranged at the vehicle body rear side.
That is, yielding 85 can be compared with reinforced rib 83 and be arranged at the vehicle body front side.
Thus, when object bumps from vehicle body the place ahead and anterior wind glass 15 (with reference to Fig. 1), first roof track 32 etc., can make shock load F 1 input to yielding 85 well.
And, possess reinforced rib 83 between the leading section 36 in the binding main body diapire 71 of left connecting part 34 and the rearward end 37, thus, make the front end 83a of reinforced rib 83 and yielding 85 (that is, peristome 86 and bight 87) be adjacent to configuration.
Thus, when object bumps from vehicle body the place ahead and anterior wind glass 15, first roof track 32 etc., can make stress concentrate on yielding 85.
Like this, make shock load F1 input to yielding 85 well, and make stress concentrate on yielding 85; thus; can make distortion permission portion 101 is starting point good (reliably) distortion with yielding 85, can further improve object (for example, pedestrian's) protective value.
And, as Fig. 8, shown in Figure 10, possessing yielding 85 at the leading section 36 of left connecting part 34, near the distortion permission portion 101 can only making yielding 85 thus is out of shape well.
On the other hand, can suppress the rigid portion 102 of the first roof track 32, the rigid portion 38 of left connecting part 34 deforms.
For rigid portion 102, with rigid portion 38 in the same manner, with yielding 85 near distortion permission portion 101 compare the mode that is difficult to be out of shape and form.
Thus, can deform by the rigid portion 102 of the first roof track 32, the space that the rigid portion 38 of left connecting part 34 suppresses in car chamber 13 (with reference to Fig. 1).Like this, by deforming in the inhibition car chamber 13, can protect the occupant in the car chamber 13 well.
In addition, possess reinforced rib 83 between the leading section 36 in linking main body diapire 71 and the rearward end 37, can further improve the rigidity (intensity) of left connecting part 34 thus by reinforced rib 83.
Thus, thus can by about connecting part 34 guarantee that fully the rigidity of the first roof track 32 and the second roof track 33 fully improves the rigidity (intensity) of body construction 12.
Thus, the space that suppresses in car chamber 13 (with reference to Fig. 1) by body construction 12 deforms, and therefore can further protect the occupant in the car chamber 13 well.
And, by the rigidity of abundant raising body construction 12, can further guarantee vibration suppression (vibrationproof), noise suppression (soundproof).
Below, the front upper part that inputs to body construction 12 from vehicle body top for shock load (namely, track element) 31 example, shock load input to the example of the 28a of front upper side portion (that is, about the front portion of roof siding track 28) of body construction 12 from the vehicle body side, describe according to Figure 13.
As shown in figure 13, consider that following situation: shock load F2 acts on the front upper part (track element) 31 of body construction 12 as shown by arrows from the top.
In addition, consider that following situation: shock load F3 acts on the 28a of the front upper side portion front portion of roof siding track 28 (about) of body construction 12 as shown by arrows from the side.
Therefore, by about front pillar top 25c, about anterior 28a and the first roof track 32 of roof siding track 28 form roughly first skeleton portion 42 of コ word shape.And, form the roughly first cyclic skeleton portion 41 of mouthful word shape by the lower part 25b of first skeleton portion 42, left front post 25, lower part 25b and the floor board 23 of right front post 25.
In addition, by about subpost 25d, about anterior 28a and the second roof track 33 of roof siding track 28 form roughly second skeleton portion 45 of コ word shape.And, form the roughly second cyclic skeleton portion 44 of mouthful word shape by the lower part 25b of second skeleton portion 45, left front post 25, lower part 25b and the floor board 23 of right front post 25.
Thus, the rigidity (intensity) of the roof track element 31 of body construction 12 is improved.
And, by about 34 pairs of first skeleton portion 42 of connecting part and second skeleton portion 45 link, about connecting part 34 possess the reinforced rib 83 of strengthening usefulness.
Thus, shock load F2 as shown by arrows from above input under the situation of roof track element 31, can make the shock load F2 that inputs to skeleton portion in first skeleton portion 42 and second skeleton portion 45, a side via about connecting part 34 be dispersed to the opposing party's skeleton portion.
In addition, under the situation of the anterior 28a of the roof siding track 28 about shock load F3 inputs to from the side as shown by arrows, can make the load that inputs to skeleton portion in first skeleton portion 42 and second skeleton portion 45, a side via about connecting part 34 be dispersed to the opposing party's skeleton portion.
That is, have in input under the situation of shock load F2, shock load F3, skeleton portion that can be by the opposing party supports the skeleton portion of the side in first skeleton portion 42 and second skeleton portion 45.
Thus, can further improve the rigidity (intensity) of the roof track element 31 of body construction 12.
Like this, the rigidity (intensity) of the roof track element 31 by improving body construction 12, input under the situation of roof track element 31 at shock load F2, under the situation of the anterior 28a of the roof siding track 28 of shock load F3 about inputing to, can prevent that roof track element 31 is out of shape to car chamber 13 sides.
Thus, can deform by the space that body construction 12 suppresses in the car chamber 13, therefore can further protect the occupant in the car chamber 13 well.
