As a result, the space inside the lower buffer section 23 is also used as a space for routing various piping materials connected to the in-vehicle device 12.
  • the lower buffer section 23 is provided with a lower left surface section 35, a lower rear surface section 36, and a lower right surface section 37.
  • the lower left surface section 35, the lower rear surface section 36, and the lower right surface section 37 are each disposed substantially vertically.
  • the horizontal cross-sectional shape of the lower buffer section 23 can be considered to be a shape combining three linear portions (e.g., a U-shape, a C-shape, or a channel shape).
  • the lower left surface portion 35 is a flat portion that is welded and fixed to the third surface portion 34 of the fixing portion 22 in surface contact therewith.
  • the lower rear surface portion 36 is a planar portion formed so as to extend rightward from the rear end portion of the lower left surface portion 35, and is formed substantially perpendicular to the lower left surface portion 35.
  • the position of the lower rear surface portion 36 in the front-rear direction is set rearward of the rear auxiliary portion 57 when viewed from above the in-vehicle device 12, as shown in FIG.
  • the lower right surface portion 37 is a planar portion formed to extend forward from the right end portion of the lower rear surface portion 36, and is formed substantially perpendicular to the lower rear surface portion 36.
  • the left-right position of the lower right surface portion 37 is set to the right of the right auxiliary portion 55 when viewed from above the in-vehicle device 12, as shown in FIG.
  • the right rear surface 40 of the right enclosing portion 18 and the second surface 32 of the fixing portion 22 are welded to the left rear surface 43 of the left enclosing portion 19 so as not to overlap.
  • the dashed line in FIG. 4 is the contour line of the second surface 32 fixed to the left rear surface 43
  • the dashed line in FIG. 4 is the contour line of the right rear surface 40 fixed to the left rear surface 43.
  • the lower end of the left rear surface 43 which is fixed to the second surface 32, extends to a position close to the ridge 38 of the first surface 31 and the second surface 32.
  • the rigidity of the second surface 32 side is relatively high and the rigidity of the first surface 31 side is relatively low, with the ridge 38 of the first surface 31 and the second surface 32 as the boundary.
  • the portion on the first surface 31 side is more likely to bend and deform than the ridge 38 of the first surface 31 and the second surface 32. Therefore, the bending deformation of the portion on the left rear surface 43 side to which the second surface 32 is fixed is relatively suppressed, and the protection performance of the in-vehicle device 12 is improved.
  • Action 6 is a diagram for explaining the deformation of the accommodation chamber 1 and the protector 15 due to an external force indicated by a white arrow.
  • these members move rearward together with the side member 2 and the front subframe 7, and the fender shield 10 may be deformed into a folded state.
  • the protector 15 of the on-vehicle device 12 fixed to the fender shield 10 also moves rearward with the deformation of the fender shield 10.
  • the upper buffer portion 20 of the protector 15 abuts against the cowl top panel 9.
  • the cowl top panel 9 is pushed rearward and upward, and the upper buffer portion 20 itself deforms to absorb the impact, thereby effectively protecting the on-vehicle device 12.
  • the protector 15 is provided with a fixing portion 22 having a first surface portion 31 and a second surface portion 32.
  • the first surface portion 31 is fixed to the fender shield 10 (base portion 11), and the second surface portion 32 is fixed to the body portion 16 of the protector 15 with a shape that stands upright relative to the first surface portion 31.
  • the fixing portion 22 is easier to deform so that the angle formed by the first surface portion 31 and the second surface portion 32 increases, improving the effect of suppressing the rearward tilt of the vehicle-mounted device 12.
  • the fixed state of the first surface portion 31 relative to the fender shield 10 is easier to maintain, and the effect of suppressing the forward tilt of the vehicle-mounted device 12 is also improved. Therefore, the posture of the vehicle-mounted device 12 is maintained almost vertically, and it is easier to ensure a buffer space between the dash panel 8 and the vehicle-mounted device 12.
  • a deformation inducer 33 is formed between the first surface 31 and the second surface 32. This ensures appropriate rigidity for the fixing portion 22, and promotes deformation in the portion closer to the first surface 31 than the ridge line 38 of the first surface 31 and the second surface 32 when the leg 17 is deformed by an external force.
  • a left rear surface 43 is fixed to the back side of the second surface 32, extending to a position close to the ridge line 38 of the first surface 31 and the second surface 32. This makes the second surface 32 side closer to the ridge line 38 more rigid than the first surface 31 side. Therefore, as shown by the dashed line in FIG. 7, bending deformation is more likely to occur at the bend line portion 60 located closer to the first surface 31 than the ridge line 38, and bending deformation on the second surface 32 side is suppressed.
  • the above mounting structure is a mounting structure for an on-vehicle device 12 that is mounted to the fender shield 10 while being surrounded by a protector 15.
  • the protector 15 includes a body portion 16 that is attached to the on-vehicle device 12 so as to cover the periphery of the on-vehicle device 12, and a leg portion 17 that is provided on a lower portion of the body portion 16 and fixed to the fender shield 10.
  • the leg portion 17 has a first surface portion 31, a second surface portion 32, and a deformation inducing portion 33.
  • the first surface portion 31 is fixed to the fender shield 10.
  • the second surface portion 32 is formed in a shape that stands upright relative to the first surface portion 31 and is fixed to the body portion 16.
  • the deformation inducing portion 33 induces deformation on the first surface portion 31 side relative to a ridge line 38 that forms a boundary between the first surface portion 31 and the second surface portion 32 when the leg portion 17 is deformed by an external force.
  • the deformation inducing portion 33 may be disposed, for example, at the end of the ridge line 38 (i.e., one end), or may be formed in a surface that intersects with both the first surface portion 31 and the second surface portion 32.
  • This configuration provides a simple shape that is easy to process and form, and provides appropriate rigidity in the vicinity of the ridge line 38, and can more reliably induce deformation on the first surface portion 31 side of the ridge line 38. This improves the protective performance of the in-vehicle device 12 while stabilizing its mounting state.
  • the deformation inducing portion 33 may be provided at both ends of the ridge line 38.
  • the fold line portion 60 can be made approximately parallel to the ridge line 38, and bending deformation on the second surface portion 32 side can be more reliably prevented.
  • the overall shape of the protector 15 can be designed after predicting the position and shape of the leg portion 17 after the fold line portion 60 is bent, making it easier to control the deformation state of the protector 15.
  • the first surface 31 may be formed to be substantially flat. This configuration can create a gap in the bending rigidity of the first surface 31 relative to the second surface 32, and can promote deformation on the first surface 31 side relative to the ridge line 38. This can improve the protection performance of the in-vehicle device 12.
  • a portion of the body 16 (left rear surface 43) to which the second surface 32 is fixed may be extended to a position close to the ridge line 38 of the first surface 31 and the second surface 32, as shown in FIG. 4.
  • the second surface 32 side of the ridge line 38 has higher rigidity than the first surface 31 side. Therefore, as shown by the dashed line in FIG. 7, bending deformation at the fold line portion 60 on the first surface 31 side of the boundary portion between the first surface 31 and the second surface 32 can be promoted, and bending deformation on the second surface 32 side can be suppressed. Therefore, deformation or damage to the filter body 13 caused by deformation of the second surface 32 or the left rear surface 43 can be prevented, and the protective performance of the in-vehicle device 12 can be improved.
  • the body 16 of the protector 15 may be disposed in front of the cowl top panel 9 in a side view and have an upper buffer section 20 that protrudes toward the rear of the vehicle in a top view.
  • the upper buffer section 20 can be brought into contact with the cowl top panel 9 quickly. This prevents interference between the in-vehicle device 12 and the cowl top panel 9, and enhances the effect of suppressing the rearward tilt of the in-vehicle device 12.
  • cowl top panel 9 can be pushed rearward and upward, improving the protective performance of the on-board device 12.
  • deformation of the upper buffer section 20 itself can absorb the impact, improving the protective performance of the on-board device 12.
  • routing the piping connection section 14 and various piping materials inside the upper buffer section 20 damage to these items can be effectively prevented.
  • the legs 17 of the protector 15 may have a shape that protrudes toward the rear of the vehicle when viewed from above, and may have a lower buffer section 23 that is arranged to overlap the upper buffer section 20.
  • the inside of the upper buffer section 20 and the lower buffer section 23 can be easily used as a space for routing the pipe connection section 14 and various pipe materials, and damage to these can be effectively prevented.
  • the in-vehicle device 12 may be disposed to the side of the vehicle's drive source.
  • the body portion 16 may have a right enclosing portion 18 (enclosing portion) that separates the in-vehicle device 12 from the drive source in a top view and extends above the upper end of the in-vehicle device 12. This configuration can prevent interference between the piping connection portion 14 and the drive source, improving the protective performance of the in-vehicle device 12.
  • the components constituting the protector 15 in the above embodiment can be modified as appropriate and can be partially omitted.
  • the upper buffer section 20, the lower buffer section 23, and the auxiliary section 21 can be omitted, or an integrated member corresponding to the right enclosing section 18 and the left enclosing section 19 can be provided as the body section 16.
  • a protector 15 having at least the body section 16 and the legs 17 a structure that provides the same effect as the above embodiment can be realized by providing the legs 17 with the first surface section 31, the second surface section 32, and the deformation inducing section 33.
  • the fender shield 10 in the above embodiment may be a planar member that forms part of the bottom surface of the accommodation chamber 1 inside the vehicle's fender panel, and may be, for example, part of the bottom surface of the rear power unit room inside the rear fender panel.
  • the accommodation chamber 1 is disposed at the rear of the vehicle cabin.
  • a protector 15 that is fixed to such a fender shield 10 a structure that provides the same effect as the above embodiment can be realized by providing a first surface portion 31, a second surface portion 32, and a deformation inducing portion 33 on the leg portion 17.
  • This invention can be used as a mounting structure for vehicle-mounted devices, and can be used in the vehicle manufacturing industry where vehicle-mounted devices are mounted via the mounting structure.
