Outer link sidewall 34c crosses over the first rear wall 54 and the second antetheca 62 ground is arranged.

Outside portion 34e (the opposing party) this outer link sidewall 34c sidepiece (counter-lateral quadrents) 34d, 34e inside and outside the overall width direction linking diapire 34a erects.

As shown in Figure 8, Figure 9, for connecting part main body 35, link main body diapire 71 and inside and outside link main body wall 72,74 are formed as roughly U-shaped, cross section.In addition, for leading section 36, front link diapire 77, front madial wall rake 93 and front lateral wall rake 95 are formed as roughly U-shaped, cross section.Further, for rearward end 37, rear link diapire 78, rear madial wall rake 94 and rear lateral wall rake 96 are formed as roughly U-shaped, cross section.

Like this, connecting part main body 35, leading section 36 and rearward end 37 are formed as cross section roughly respectively " コ " shape.

Thus, for left connecting part 34, be formed as U-shaped cross-section by the link diapire 34a shown in Figure 11, interior link sidewall 34b and the outer sidewall 34c that links.

By left connecting part 34 is configured to U-shaped cross-section, the rigidity (intensity) of left connecting part 34 can be improved further.

Right connecting part 34 is and the symmetrical parts of left connecting part 34, following detailed.

As described above, by the connecting part 34 (right connecting part 34 is with reference to Fig. 4) of left and right, the first roof track 32 and the second roof track 33 one (roughly well type) are linked, further, the connecting part 34 of left and right made U-shaped cross-section thus improve the rigidity (intensity) of connecting part 34 of left and right.

Thereby, it is possible to the load (shock load) making to input to roof track in the first roof track 32 and the second roof track 33, a side is dispersed to the roof track of the opposing party well via the connecting part 34 of left and right.

That is, roof track in the first roof track 32 and the second roof track 33, the opposing party can be utilized to support the roof track of a side.

Specifically, the load that can make to input to the first roof track 32 is dispersed to the second roof track 33 well via the connecting part 34 of left and right.In addition, the load that can make to input to the second roof track 33 is dispersed to the first roof track 32 well via the connecting part 34 of left and right.

That is, the second roof track 33 can be utilized and connecting part 34 via left and right supports the first roof track 32.In addition, the first roof track 32 can be utilized and connecting part 34 via left and right supports the second roof track 33.

Thereby, it is possible to fully guarantee the rigidity of the first roof track 32 and the second roof track 33 thus the rigidity (intensity) of raising roof track element 31 (that is, body construction 12) by the connecting part 34 of left and right.

Therefore, it is possible to guarantee the space of the car room 13 shown in Fig. 2, and guarantee vibration suppression (vibrationproof), noise suppression (soundproof).

Further, as shown in Figure 2, the first skeleton portion 42 and the second skeleton portion 45 are linked by the connecting part 34 of left and right.Thereby, it is possible to the load making to input to skeleton portion in the first skeleton portion 42 and the second skeleton portion 45, a side is dispersed to the skeleton portion of the opposing party via the connecting part 34 of left and right.

That is, the skeleton portion of the skeleton portion of the opposing party to a side of the first skeleton portion 42 and the second skeleton portion 45 can be utilized to support.

Thereby, it is possible to fully guarantee the rigidity of the first skeleton portion 42 and the second skeleton portion 45 thus the rigidity (intensity) on rigidity, particularly the vehicle front top of raising body construction 12.

In addition, as shown in Figure 4, link the first roof track 32 and the second roof track 33 integratedly by the connecting part 34 of left and right, thus, formed the roof track element 31 of roughly well type by the connecting part 34 of the first roof track 32, second roof track 33 and left and right.

Thus, the roof siding track 28 about being temporarily fixed on by roof track element 31 by utilizing temporary setting jig, can be temporarily fixed on the roof siding track 28 of left and right by a temporary setting jig by first, second roof track 32,33.

That is, independent temporary setting jig need not be used respectively the first track 32 and the second track 33 to be temporarily fixed on the roof siding track 28 of left and right.

Thereby, it is possible to the number of the temporary setting jig used when first, second roof track 32,33 being assembled in the roof siding track 28 of left and right is reduced to one from two.

By reducing the number of temporary setting jig, when first, second roof track 32,33 being assembled in the roof siding track 28 of left and right, assembling operation can be improved.

And, by roof track element 31 is formed integrally as roughly well type, the rigidity (shape stability) of roof track element 31 can be improved further.

Thus, the operability (treatability) when roof track element 31 being assembled in the roof siding track 28 of left and right is easier, can improve assembling operation further.

As shown in Figure 10, Figure 12, on left connecting part 34, possesses aforesaid yielding portion 85 at leading section 36.

Yielding portion 85 possesses peristome 86 and bight 87, and bight 87 and peristome 86 are configured in overall width direction (arrow A direction) upper overlapping position.

Like this, owing to possessing yielding portion 85 at the leading section 36 of left connecting part 34, the distortion permission portion 101 (with reference to Figure 10) near yielding portion 85 is formed to hold yielding mode compared with the rigid portion 38 of left connecting part 34.

Distortion permission portion 101 is the positions near the yielding portion 85 in the first roof track 32 and left connecting part 34 etc.

Peristome 86 is with the elongated hole that the mode extended towards overall width direction (arrow A direction) is formed on the diapire position 77a in front link diapire 77.

For the 77a of diapire position, be in front link diapire 77, the first diapire 51 and front link diapire 77 link, and the position between sidewall slope portion 93,95 inside and outside before being positioned at.

This peristome 86, in detail, with from inner 86a 86b tilting with tiltangleθ relative to overall width direction (arrow A direction) to the mode that vehicle front gently tilts outward.

Like this, formed in the mode extended towards overall width direction by means of only by peristome 86, just can form yielding portion 85 simply.

Further, the length dimension L by changing the peristome 86 extended towards overall width direction just can change the rigidity in yielding portion 85 simply.By changing the rigidity in yielding portion 85, the deformation state (deformation pattern) in yielding portion 85 can be adjusted.

Thus, when object collides from vehicle front and anterior wind glass 15, first roof track 32 etc., the distortion permission portion 101 (with reference to Figure 10) near yielding portion 85 can be made reliably to be out of shape using yielding portion 85 as starting point.

Here, inside and outside link sidewall 34b, 34c extend along vehicle body fore-and-aft direction.Thus, when making inside and outside link sidewall 34b, 34c directly be communicated with the first rear wall 54 of the first roof track 32, inside and outside link sidewall 34b, 34c and the link bight (bight) of the first roof track 32, for elbows, become the position not easily deformed relative to load (shock load) F1 from vehicle front.

Therefore, make to be folded with bight 87 between the first rear wall 54 and inside and outside link main body wall 72,74, the part of bight 87 as yielding portion 85 is used.

Bight 87 is formed in the mode linked between the first rear wall 54 and inside and outside link main body wall 72,74.

Specifically, bight 87 has: the inside and outside rear wall rake (rear wall rake) 91,92 that the first rear wall 54 possesses; The front madial wall rake (sidewall slope portion) 93 that interior link main body wall 72 possesses; The front lateral wall rake (sidewall slope portion) 95 that outer link main body wall 74 possesses.

Inside and outside rear wall rake 91,92 make with in the first rear wall 54 inside and outside position corresponding to link sidewall 34b, 34c (with reference to Figure 11) to vehicle body rear side with the position that tilts, the mode bending of the kernel of section 98 close to U-shaped cross-section (connecting part) 34 ground.

Front madial wall rake 93 is in the mode that can link with interior rear wall rake 91, from the front end 72b of interior link main body wall 72 to vehicle front and to from kernel of section 98 away from the position that tilts, curving shape ground.

Front lateral wall rake 95 is in the mode that can link with outer rear wall rake 92, from the front end 74b of outer link main body wall 74 to vehicle front and to from kernel of section 98 away from the position that tilts, curving shape ground.

Thus, for bight 87, tilt the mode bending gently expanded with the first rear wall 54 from front end 72b and front end 74b to vehicle front.

Thus, bight 87 is formed as holding yielding shape relative to the shock load F1 from vehicle front, vehicle body front upper place.

Like this, peristome 86 and bight 87 is possessed at the leading section 36 of left connecting part 34 as yielding portion 85.

Thus, when object collides from the anterior wind glass 15 (with reference to Fig. 1), the first roof track 32 etc. of vehicle front and vehicle 10, the distortion permission portion 101 near yielding portion 85 can be made to be out of shape well using yielding portion 85 as starting point thus to absorb impulsive force F1.

Thereby, it is possible to suppress to give the impulsive force F1 of object thus the protective value of raising object (such as, pedestrian).

Particularly, bight 87 tilts to vehicle front in the mode gently expanded, and thus, is formed as holding yielding shape relative to the shock load F1 from vehicle front, vehicle body front upper place.

Thus; when object collides from vehicle front and anterior wind glass 15 (with reference to Fig. 1), the first roof track 32 etc.; bight 87 can be made to be out of shape well, thus to improve the protective value of object (such as, pedestrian) further.

Further, bight 87 and peristome 86 are configured in overall width direction (arrow A direction) upper overlapping position.

Thus, when object collides from vehicle front and anterior wind glass 15 (with reference to Fig. 1), the first roof track 32 etc. thus inputs shock load F1 from vehicle front, vehicle body front upper place, can utilize the shock load F1 of input that bight 87 and peristome 86 are out of shape simultaneously.

Thereby, it is possible to utilize the shock load F1 of input to make the distortion permission portion 101 near yielding portion 85 with yielding portion 85 for starting point well (reliably) is out of shape.

Like this, distortion permission portion 101 is out of shape for starting point well with yielding portion 85, the protective value of object (such as, pedestrian) can be improved thus further.

In addition, possess reinforced rib 83 between the leading section 36 in the link main body diapire 71 of left connecting part 34 and rearward end 37, thus, reinforced rib 83 is arranged at vehicle body rear side compared with yielding portion 85.

That is, yielding portion 85 can be arranged at vehicle front side compared with reinforced rib 83.

Thus, when object collides from vehicle front and anterior wind glass 15 (with reference to Fig. 1), the first roof track 32 etc., shock load F1 can be made to input to yielding portion 85 well.

Further, between the leading section 36 in the link main body diapire 71 of left connecting part 34 and rearward end 37, possess reinforced rib 83, thus, make the front end 83a of reinforced rib 83 and yielding portion 85 (that is, peristome 86 and bight 87) be adjacent to configure.

Thus, when object collides from vehicle front and anterior wind glass 15, first roof track 32 etc., stress can be made to concentrate on yielding portion 85.

Like this; shock load F1 is made to input to yielding portion 85 well; and make stress concentrate on yielding portion 85; thus; distortion permission portion 101 can be made with yielding portion 85 for starting point good (reliably) distortion; the protective value of object (such as, pedestrian) can be improved further.

And, as shown in Fig. 8, Figure 10, possess yielding portion 85 at the leading section 36 of left connecting part 34, can only make the distortion permission portion 101 near yielding portion 85 be out of shape well thus.

On the other hand, the rigid portion 102 of the first roof track 32 can be suppressed, the rigid portion 38 of left connecting part 34 deforms.

For rigid portion 102, identically with rigid portion 38, formed in the mode being difficult to be out of shape compared with the distortion permission portion 101 near yielding portion 85.

Thereby, it is possible to suppress the space in car room 13 (with reference to Fig. 1) to deform by the rigid portion 102 of the first roof track 32, the rigid portion 38 of left connecting part 34.Like this, by suppressing to deform in car room 13, the occupant in car room 13 can be protected well.

In addition, between the leading section 36 linked in main body diapire 71 and rearward end 37, possess reinforced rib 83, the rigidity (intensity) of left connecting part 34 can be improved thus by reinforced rib 83 further.

Thereby, it is possible to fully guarantee the rigidity of the first roof track 32 and the second roof track 33 thus the rigidity (intensity) of fully raising body construction 12 by the connecting part 34 of left and right.

Thus, the space in car room 13 (with reference to Fig. 1) is suppressed to deform, therefore, it is possible to protect the occupant in car room 13 well further by body construction 12.

Further, by fully improving the rigidity of body construction 12, vibration suppression (vibrationproof), noise suppression (soundproof) can be guaranteed further.

Below, (namely the front upper part of body construction 12 is inputed to for shock load above vehicle body, track element) 31 example, shock load input to the front upper sidepiece of body construction 12 (namely from vehicle body side, the front portion of roof siding track 28 of left and right) example of 28a, be described according to Figure 13.

As shown in figure 13, following situation is considered: shock load F2 acts on the front upper part (track element) 31 of body construction 12 as shown by arrows from top.

In addition, following situation is considered: shock load F3 acts on front upper sidepiece (front portion of the roof siding track 28 of the left and right) 28a of body construction 12 as shown by arrows from side.

Therefore, the first skeleton portion 42 of roughly U-shaped is formed by the anterior 28a of the front pillar top 25c of left and right, the roof siding track 28 of left and right and the first roof track 32.Further, the first ring-type skeleton portion 41 of roughly mouth shape is formed by the lower part 25b of the first skeleton portion 42, left front post 25, the lower part 25b of right front post 25 and floor board 23.

In addition, the second skeleton portion 45 of roughly U-shaped is formed by the anterior 28a of the subpost 25d of left and right, the roof siding track 28 of left and right and the second roof track 33.Further, the second cyclic skeleton portion 44 of roughly mouth shape is formed by the lower part 25b of the second skeleton portion 45, left front post 25, the lower part 25b of right front post 25 and floor board 23.

Thus, the rigidity (intensity) of the roof track element 31 of body construction 12 is improved.

And, by the connecting part 34 of left and right, the first skeleton portion 42 and the second skeleton portion 45 are linked, possess the reinforced rib 83 strengthened at the connecting part 34 of left and right.

Thus, when shock load F2 inputs to roof track element 31 as shown by arrows from top, the shock load F2 that can make to input to skeleton portion in the first skeleton portion 42 and the second skeleton portion 45, a side is dispersed to the skeleton portion of the opposing party via the connecting part 34 of left and right.

In addition, when shock load F3 inputs to the anterior 28a of roof siding track 28 of left and right as shown by arrows from side, the load that can make to input to skeleton portion in the first skeleton portion 42 and the second skeleton portion 45, a side is dispersed to the skeleton portion of the opposing party via the connecting part 34 of left and right.

That is, when input has shock load F2, shock load F3, can be supported by the skeleton portion of the skeleton portion of the opposing party to the side in the first skeleton portion 42 and the second skeleton portion 45.

Thereby, it is possible to improve the rigidity (intensity) of the roof track element 31 of body construction 12 further.

Like this, by improving the rigidity (intensity) of the roof track element 31 of body construction 12, when shock load F2 inputs to roof track element 31, shock load F3 is when inputing to the anterior 28a of roof siding track 28 of left and right, and roof track element 31 can be prevented to be out of shape to side, car room 13.

Thereby, it is possible to suppress the space in car room 13 to deform by body construction 12, therefore, it is possible to protect the occupant in car room 13 further well.

Below, for shock load from the front of body construction 12, front upper place inputs to the example of roof track element 31, be described according to Figure 14, Figure 15.

As shown in Figure 14 (a), consider following situation: object from the front of body construction 12, front upper place and anterior wind glass 15 (with reference to Fig. 1), the first roof track 32 etc. collide.

Therefore, as shown in Figure 14 (b), at the leading section 36 of left connecting part 34, as yielding portion 85, peristome 86 and bight 87 are configured in overall width direction (arrow A direction) upper overlapping position.

In addition, make the vehicle body rear side in the front end 83a of reinforced rib 83 and yielding portion 85 adjacent, thus make stress concentrate on yielding portion 85.

Further, bight 87 is tilted with the mode bending gently expanded to vehicle front, thus, bight 87 is formed as hold yielding shape relative to the shock load F4 from vehicle front, vehicle body front upper place.

As shown in Figure 15 (a), object from the front of body construction 12, front upper place and anterior wind glass 15 (with reference to Fig. 1), the first roof track 32 etc. collide, thus, shock load F4 inputs to the first roof track 32 from vehicle front, vehicle body front upper place.

As shown in Figure 15 (b), shock load F4 inputs to the first roof track 32 from vehicle front, vehicle body front upper place, thereby, it is possible to only make the distortion permission portion 101 near yielding portion 85 be out of shape well.

Thus, absorb shock load F4 by the distortion permission portion 101 near yielding portion 85 thus the protective value of object (such as, pedestrian) can be improved further.

On the other hand, when shock load F4 inputs, the rigid portion 102 of the first roof track 32 (with reference to Figure 14 (b)) can be suppressed, the rigid portion 38 of left connecting part 34 deforms.

Thereby, it is possible to suppress the space in car room 13 (with reference to Fig. 1) to deform by the rigid portion 102 of the first roof track 32, the rigid portion 38 of left connecting part 34.Like this, by suppressing to deform in car room 13, the occupant in car room 13 can be protected well.
