Description

[Technical Field]The present invention relates to a structure of a resin front end portion of a vehicle.[Background of Technique]On a front part of a conventional vehicle, front side members extending in the vehicle front-rear direction on both left and right sides, a support member having a frame structure, an engine assembly, a bumper member, and the like are disposed, and heat exchangers such as a radiator, a condenser, and the like are suspended at upper and lower parts of the support member (see, for example, JP H10-18843 A). A support member having such a frame structure has a frame formed of a rigid sheet metal member, and has a function of withstanding a load applied to heat exchangers such as a radiator which is rather heavy and maintaining accurate mounting of a head lamp and the like.Recently, a resin front end portion made using a resin material is used rather than a support member made of a sheet metal structure to reduce weight and improve functions. Such a resin front end portion is formed with a square frame structure having an upper member portion, left and right side side support portions, and a lower member portion, in order to secure rigidity and component fixing performance similar to that of a support member having a sheet metal structure. The side support portions on the left and right sides are suspended from a front end portion of the front side member, and the upper and lower parts of the heat exchanger are suspended from the resin front end portion.In a conventional vehicle, moreover, the heat exchanger such as a radiator, a condenser, an intercooler, and the like and the resin front end portion are raised from below and mounted as a unit on a vehicle body together with the engine assembly such as an engine, a transmission, an assist motor, and the like in a production process in an integrally mounted state, and are integrally fixed to a body frame.[Prior Art]Furthermore, resin front end sections of the above-mentioned type are known, for example, from the documents EP 2 014 501 A1, US 2010 / 0 060 039 A1, U.S. Pat. No. 8 485 295 B2 and WO 99 / 54 187 A1.[Summary of the Invention][Problem to be Solved by the Invention]However, the above-described resin front end portion having a conventional structure tends to have a lower rigidity than the support member having the sheet metal structure, and therefore, the rigidity needs to be secured by forming a large cross-sectional area of the resin front end portion. However, when the cross-sectional area of the resin front end portion is formed large to ensure rigidity, an outer end portion of the structure around this portion projects outward from the vehicle, and peripheral components such as a head lamp to be installed on the outside of the structure must be put on the outside of the vehicle, which might result in an increase in the vehicle size.On the other hand, particularly in a compact vehicle, it is required that the structure for suspending the heat exchanger does not become large and a space on the front part of the vehicle can be used similarly to the support member having the sheet metal structure, and the use of the conventional resin front end portion is not appropriate for a suspension structure for the heat exchanger. Moreover, in the case of a compact vehicle, the engine room is small, and when the resin front end portion, engine assembly, and heat exchanger assembly is lifted from below the vehicle body, the assembly is close to the peripheral members such as a front side member, an instrument panel, and the like, and therefore, in the lifting, interference with the peripheral members must be avoided by holding the assembly obliquely or rotating instead of simply lifting, and particularly, in a portion where there is only a short distance from the peripheral members or interference should be avoided, positioning of the assembly must be regulated by separately using a guide device in the lifting, thereby making assembly work cumbersome.The present invention has been made in view of the above-described circumstances, and has an object of providing a resin front end portion structure with which assembly of the resin front end portion, the engine assembly, and the heat exchanger to the vehicle body can be performed quickly and reliably in the production process while avoiding deterioration of the peripheral components by molding a guide portion or the like and achieving weight reduction and achieving rigidity of the resin front end portion by utilizing the property of a resin material having flexibility in shape for reducing the manufacturing cost and improving the fuel cost of the vehicle.[Means for Solving Problems]In order to solve the above-described problems of the conventional technologies, the present invention is configured such that, in a structure of a resin front end portion in which the resin front end portion, an engine assembly, and a heat exchanger are disposed on a front part of a vehicle, the resin front end portion is formed of a square frame structure having an upper member portion, left and right side support portions, and a lower member portion, the resin front end portion, the engine assembly, and the heat exchanger are raised from below in an integrally assembled state as an assembly, the left and right side support portions are suspended from a front side member extending in a vehicle front-rear direction and assembled to a vehicle body, wherein an upper block portion having a trapezoidal shape in a side view of the vehicle, Further, in the embodiment of the present invention, the inclined surface is provided on a side surface at each of the left and right side support portions and protrudes outward in a vehicle width direction, wherein an inclined surface extending diagonally downward toward the rear side of the vehicle is formed at an upper end portion of the upper block portion, so that when the assembly is mounted to the vehicle body, the inclined surface is brought into contact with a front end portion of the front side member and an upper part of the assembly is moved toward the front side of the vehicle.Moreover, in an advantageous aspect of the present invention, the upper block portions provided on each of the left and right side support portions have shapes different from each other by making at least a position of the inclined surface, an inclination angle, a length of the inclined surface, and a height and / or a length of the block portion different from each other.In an advantageous aspect of the present invention, a fixing portion including a reinforcing bracket for fixing the resin front end portion to the front side member and a first fixing portion of a headlight are further provided on the upper block portion.In an advantageous aspect of the present invention, moreover, the first mounting portion and a second mounting portion provided separately from the first mounting portion are used for mounting the headlight, and the second mounting portion and the first mounting portion are vertically disposed over a part of the upper block portion.Moreover, in an advantageous aspect of the present invention, the upper member portion of the resin front end portion is formed with a lattice structure sandwiched between upper and lower horizontal plane portions, and the upper part of the upper block portion is provided at a location overlapping with a space between the upper and lower horizontal plane portions of the upper member portion in a vehicle side view.[Advantageous Effects of the Invention]As described above, in the structure of the resin front end portion according to the present invention, the resin front end portion, the motor assembly, and the heat exchanger are disposed at the front part of the vehicle, the resin front end portion has the square frame structure including the upper member portion, the left and right side support portions, and the lower member portion, the resin front end portion, the motor assembly, and the heat exchanger are lifted as a sub-assembly in an integrally assembled state, the left and right side support portions are suspended from the front side members extending in the vehicle front-rear direction and assembled to the vehicle body, the upper block portion having a trapezoidal shape in the vehicle side view is provided on the side surface of each of the left and right side support portions, and protrudes outward in the vehicle width direction, the inclined surface, The upper portion of the assembly extending diagonally downward toward the rear side of the vehicle is formed on an upper end portion of the upper block portion so that the inclined surface is brought into contact with the front end portion of the front side member, and the upper part of the assembly can be moved toward the vehicle front side when the assembly is mounted on the vehicle body, so that the rigidity of the left and right side support portions can be improved by the upper block portion, and also a weight reduction of the resin front end portion and an improvement in the fuel cost of the vehicle can be achieved.Moreover, in the construction of the resin front end portion according to the present invention, when the assembly assembled by integrally assembling the resin front end portion, the engine assembly, and the heat exchanger is to be assembled, since the upper block portion performs a guiding function in cooperation with the front side member, interference of an engine bracket, an instrument panel, and components of the instrument panel, and the like constituting peripheral components of the assembly can be avoided by gradually inclining the upper part of the assembly, the assembly to the vehicle bodies in the production process can be performed quickly and reliably, productivity can be improved, and manufacturing cost can be lowered.Since the upper block portions provided on each of the left and right side support portions are formed differently by making at least a position of the inclined surface, an inclination angle and / or a length of the inclined surface, and a height and length of the block portion different, the assembly can be moved not only in the vehicle front-rear direction and in the left-right direction and in the vertical direction upon mounting to the vehicle body, but can also be moved in a rotational direction in a side view and plan view, and even if the assembly and a space in the engine compartment overlap and upright raising of the assembly results in deterioration of the peripheral components, the assembly can be raised and mounted while ensuring a distance from the peripheral components.Thereby, distances from the peripheral components only required for assembling the assembly can be reduced and the required minimum distances can be secured after completion of the assembly, so that the flexibility of the design layout of the front part in the vehicle can be increased. Moreover, by reducing wasteful distances, a space in the engine room can be used as a contribution to improvement in engine performance and collision safety by ensuring improvement in layout of intake pipes and exhaust pipes and height and width of the engine. Then, since the distance between the engine, radiator, and the like and the front side member can also be minimized, a distance between the left and right front side members can be kept small, whereby the collision safety can be improved. Moreover, since a distance between the front wheel and the front side member can be made large, a turning angle of the front wheel can be designed large, a minimum turning radius of the vehicle can be kept small, and a vehicle having a small turning circle can be developed. Moreover, since a space of the engine room can be used with play for the suspension mechanism, the steering stability of the vehicle can be improved.In an advantageous aspect of the present invention, moreover, a fixing portion including the reinforcing bracket for fixing the resin front end portion to the front side member and the first fixing portion of the headlamp are provided on the upper block portion, so that the rigid reinforcing bracket is fixed as a member for suspending the resin front end portion from the front side member, and the mounting rigidity of the resin front end portion at the time of finishing the vehicle can be improved. Moreover, the attachment of the headlight in which assembly rigidity is necessary for stability of an optical axis can also be reliably performed.Then, in an advantageous configuration of the present invention, the first mounting portion and the second mounting portion provided separately from the first mounting portion are used for mounting the headlamp, and since the second mounting portion and the first mounting portion are vertically disposed over a part of the upper block portion, the upper block portion contributes to securely mounting the headlamp besides its guiding function, and the headlamp can be reliably mounted in a state in which mounting rigidity is secured.In an advantageous aspect of the present invention, moreover, the upper member portion of the resin front end portion is formed with a lattice structure sandwiched between upper and lower horizontal plane portions, and the upper part of the upper block portion is provided at a location overlapping with a space between the upper and lower horizontal plane portions of the upper member portion in a vehicle side view, so that the upper part of the upper block portion is disposed in a corner of the resin front end portion with the frame structure, whereby the frame rigidity of the resin front end portion can be improved. By improving the frame rigidity of the resin front end portion, the upper block portion performs the guiding function and deformation of the resin front end portion is suppressed, and thus even when tilting or rotating the assemblies during assembly, positions of the entire assemblies can be maintained and stably controlled, and the assembly can be smoothly and reliably mounted on a predetermined control path on the vehicle body.[Brief Description of Drawings][FIG. 1 ] FIG. 1 is a perspective view of a resin front end portion, a heat exchanger, and a front side member to which a structure according to an embodiment of the present invention is attached, as viewed from diagonally above the front of a vehicle, in a state in which an engine assembly is not shown.[FIG. 2 ] FIG. 2 is a side view of the resin front end portion, the heat exchanger, and the front side member to which the structure according to the embodiment of the present invention is attached in a state where the engine assembly is not shown.[FIG. 3] FIG. 3 shows a first method in which the resin front end portion to which the structure according to the embodiment of the present invention is mounted on a front side member in a state in which the engine assembly and the heat exchanger are not shown, FIG. 3( a) is a side view thereof, and FIG. 3( b) is a perspective view thereof.[FIG. 4] FIG. 4 shows a method in the means of assembling the resin front end portion to which the structure according to the embodiment of the present invention is assembled to the front side member in the state where the engine assembly and the heat exchanger are not shown, FIG. 4( a) is a side view thereof, and FIG. 4( b) is a perspective view thereof.[FIG. 5 ] FIG. 5 shows a state in which the resin front end portion to which the structure according to the embodiment of the present invention is mounted on the front side member is in the state in which the engine assembly and the heat exchanger are not shown, FIG. 5( a) is a side view thereof, and FIG. 5( b) is a perspective view thereof.[FIG. 6 ] FIG. 6 is a perspective view of a state in which the resin front end portion to which the structure according to the embodiment of the present invention is mounted on the front side member through a reinforcement bracket, as viewed from the front side of the vehicle.[FIG. 7 ] FIG. 7 is a perspective view of a point in a portion A-A in FIG. 2 as viewed from the front of the vehicle.[FIG. 8] FIG. 8 is a perspective view of a state in which a headlight is attached to the resin front end portion to which the structure according to the embodiment of the present invention is attached, as viewed from the front side of the vehicle.[Mode for Carrying Out the Invention]The present invention will be described in detail below based on an illustrative embodiment. FIGS. 1 to 8 show a construction of a resin front end portion according to the embodiment of the present invention. In FIGS. 1 and 2, the direction of an arrow F points toward the front side of the vehicle.As shown in FIGS. 1 and 2, in a vehicle front part 1 to which the structure according to the embodiment of the present invention is attached, a pair of left and right front side members 2 extending in the vehicle front-rear direction and spaced apart on the right and left sides of the vehicle width direction, a resin front end portion 3 disposed on a front side of the vehicle on the front side members 2, heat exchangers (radiator, condenser, intercooler, and the like) 4 each having a planar shape on a front view of the vehicle and suspended from the resin front end portion 3, a bumper member 5 disposed on the front side of the vehicle of the resin front end portion 3, a lower bracket 6, and a lower member 7, an engine assembly (engine, transmission, and the like are provided, An assist motor and the like) which is not shown and is disposed on the rear side of the vehicle of the resin front end portion 3, and the like are provided. The front side member 2 is a rigid member constituting a main frame of the vehicle front part 1, and a crash box 8 is disposed between a front end portion 2 aof the front side member 2 and the bumper member 5.Moreover, the resin front end portion 3, the engine assembly (not shown), and the heat exchanger 4 are treated in a integrally assembled state to improve production efficiency, and are lifted from below and assembled to the vehicle body and assembled together to a vehicle body frame in a production process.The resin front end portion 3 of the embodiment is, as shown in FIGS. 1 to 8, formed of a square frame structure having an upper member portion (lamp support member) 9, side support portions (lamp supports) 10 on the left and right sides, and a lower member portion (radiator support member) 11, and the resin front end portion 3 is suspended from the front side member 2 by fixing the side support portions 10 on both the left and right sides to a front end portion 2 aof the front side member 2. The upper member portion 9 is, as shown in FIGS. 1 and 7, disposed on the upper part of the resin front end portion 3 extending in the vehicle width direction, and is formed with a lattice structure having a space S sandwiched between the upper and lower horizontal plane portions 9 aand 9 b. Moreover, the lower member portion 11 is disposed on a lower part of the resin front end portion 3 and extends in the vehicle width direction. Further, the side support portion 10 is disposed on both left and right sides in the vehicle width direction of the resin front end portion 3 and extends in a vertical direction of the vehicle, and the upper member portion 9 and the lower member portion 11 are connected to each other via the side support portions 10.A central support portion 12 extending in the vehicle vertical direction is disposed in the vicinity of the vehicle width direction central part of the resin front end portion 3, and upper and lower end portions of the central support portion 12 are connected to the upper member portion 9 and the lower member portion 11.The heat exchanger 4 is suspended and supported at upper and lower suspension positions on the left and right sides of the upper member portion 9 and the lower member portion 11, respectively, as shown in FIG. 1, being disposed in a space surrounded by the upper member portion 9, the left side support portion 10, the lower member portion 11, and the middle support portion 12. That is, it is configured such that the suspension to the upper member portion 9 is performed by an engagement between an upper heat exchanger holding member 4 adisposed on an upper part of the heat exchanger 4 and an upper heat exchanger holding portion 9 cprovided on a lower side of the upper member portion 9. Moreover, it is configured such that the suspension to the lower element portion 11 is performed by an engagement between the one heat exchanger lower holding portion (not shown) provided on the left and right sides on a lower side of the heat exchanger 4 and one heat exchanger lower holding portion (not shown) of the lower element portion 11.In the construction of the resin front end portion 3 of the embodiment, moreover, on an upper part of an outer side of each of the side support portions 10 on the left and right sides as shown in FIGS. 2 to 7, an upper block portion 13 of trapezoidal shape in a side view of the vehicle is provided protruding outward in the vehicle width direction. That is, an outer peripheral wall of the upper block portion 13 is formed in a trapezoidal shape in a lateral arrangement, the front and rear portions of the wall extend parallel substantially vertically downward and upper and lower portions thereof extend at an inclination, and an inner side surrounded by the outer peripheral wall is divided into a plurality of (four in the embodiment) chambers which are juxtaposed in the vertical direction by arranging a plurality of planar ribs 23, thereby improving the rigidity.Thus, an inclined surface 13 aextending diagonally downward toward the rear side of the vehicle is formed on the upper end portion of the upper block portion 13, and is configured such that when assembling assemblies such as the resin front end portion 3 or the like into the vehicle body, the inclined surface 13 ais brought into contact with the front end portion 2 aof the front side member 2, and upper parts of the assemblies such as the resin front end portion 3 or the like are inclined toward the front side of the vehicle. Therefore, the upper block portion 13 functions as a guide portion, and by raising the assemblies to be mounted to bring the inclined surface 13 aof the upper block portion 13 into contact with a lower surface of the front end portion 2 aof the front side member 2, and by further raising the assemblies to the above state, the upper parts of the assemblies are gradually inclined toward the front of the vehicle along the inclined surfaces 13 aof the upper block portion 13, and interference with the peripheral components disposed in the periphery of the assemblies is avoided.Moreover, the upper block portions 13 are provided to have trapezoidal shapes different from each other on each of the left and right side support portions 10. The left and right upper block portions 13 are thus formed trapezoidally, and at least a position of the inclined surface, an inclination angle and a length of the inclined surface 13 a, and a protruding height and a length of the block portion are different, respectively. By making the left and right upper block portions 13 different in trapezoidal shapes from each other, even if raising the assembly such as the resin front end portion 3 to an upright position results in deterioration of the peripheral components of the engine room upon mounting to the vehicle body, by selecting the left and right upper block portions 13, respectively, and by bringing the upper part of the assembly into contact with the inclined surface 13 aof the selected upper block portion 13, the assembly can be moved in the vehicle front-rear direction and in the left-right direction and in the vehicle vertical direction, or it can be moved in a rotational direction in a side view and a plan view to change the direction of the assembly, and the assembly can be raised and mounted while ensuring a distance from the peripheral components.As a result, only a required minimum distance can be secured after the assembly of the assembly is completed, and improvement of engine performances and improvement of collision safety are effectively achieved by utilizing the small space in the engine room. On the lower part of the outer side of each of the side support portions 10 on the left and right sides, as shown in FIGS. 2, 3 and 5, a square lower block portion 14 that protrudes outward in the vehicle width direction is provided in the side view of the vehicle.Moreover, in the upper block portion 13 of the embodiment, as shown in FIGS. 3 to 8, a fixing portion 16 having a reinforcing bracket 15 for fixing the side support portion 10 of the resin front end portion 3 to the front end portion 2 aof the front side member 2 and a first fixing portion 18 of a headlight 17 are provided. The reinforcement bracket 15 is fixed to the side support portion 10 side in a state of being disposed on the front side of the vehicle in the upper block portion 13. The brackets are rigid members for improving the mounting rigidity of the resin front end portion 3 when the vehicle is completed.Thus, the reinforcement bracket 15 has a length in the vertical direction that extends from a position on a lower half of the upper block portion 13 to an upper position of the lower block portion 14 and is formed by being folded over and has a substantially L-shaped cross section and a fastening surface that can be overlapped with the side surface of the side support portion 10, the vertical surface 13 bon the front side of the upper block portion 13, and the surface of the front end portion 2 aof the front side member 2. Upper and lower fastening surfaces 15 aand 15 bof the reinforcement bracket 15 are formed with long lengths in the vehicle front-rear direction and the vertical direction, and are configured to be fixed by a bolt to the side surface of the side support portion 10. Moreover, the fixing surface on the rear side of the upper part of the reinforcing bracket 15 is formed with a long length in the width direction, and is fixed with a bolt to the vertical surface 13 bon the front side of the upper block portion 13 as the fixing portion 16. Moreover, an intermediate fixing surface 15 cof the reinforcement bracket 15 is formed with long lengths in the vertical direction and the width direction and is fixed with a bolt to the surface of the front end portion 2 aof the front side member 2 in a state of being overlapped in the vehicle front-rear direction.In the construction of the embodiment, the mounting portion 16 and the first mounting portion 18 are configured as the same portion, and the reinforcement bracket 15 and the headlight 17 are connected to the vertical surface 13 bon the front side of the upper block portion 13 at the mounting portion 16 and the first mounting portion 18.In the attachment of the headlight 17, moreover, as shown in FIGS. 2 and 8, a second attachment portion 19 provided separately from the first attachment portion 18 is used, and the second attachment portion 19 is provided on the upper part of the side support portion 10 above the first attachment portion 18. Thus, the headlight 17 is provided with a lamp portion 17 bon a main body portion 17 aand the vehicle front side of the main body portion 17 a, and horizontally widthwise extending support members 20 and 21 are disposed on the side of the main body portion 17 alocated at the side support portion 10 at a vertical interval. Therefore, the headlight 17 is fastened and fixed to the side support portions 10 by being fastened with a bolt in a state in which distal end portions 20 aand 21 aof these support pieces 20 and 21 are disposed on the corresponding first fastening portion 18 and the second fastening portion 19.Moreover, the second mounting portion 19 and the first mounting portion 18 are vertically disposed over a part of the upper block portion 13, and are configured such that the upper block portion 13 contributes to mounting the headlight 17. Thereby, the headlight 17 is reliably fixed by the side support portions 10 while ensuring the required mounting rigidity.On the other hand, in the embodiment, as shown in FIGS. 2, 7, and 8, the upper part of the upper block portion 13 is provided in a position overlapping a space S of upper and lower horizontal plane portions 9 aand 9 bof the upper member portion 9 in the side view of the vehicle. That is, in the construction of the embodiment, the upper part of the upper block portion 13 is disposed at the corner of the resin front end portion 3 having the frame construction, and the frame rigidity of the resin front end portion 3 is improved by inserting the upper block portion 13. Moreover, by improving the frame rigidity of the resin front end portion 3, deformation of the resin front end portion 3 by loads of the assembled motor assemblies and the heat exchanger 4 is suppressed, and even if the assemblies are tilted or rotated during assembly, the positions of the entire assemblies can be stably held and assembled on a predetermined control path on the vehicle body.In the structure according to the embodiment of the present invention configured as above, a method of assembling the assembly of the resin front end portion 3, the engine assembly, and the heat exchanger 4 will be described with reference to FIGS. 3 and 5. However, the engine assembly and the heat exchanger 4 have been omitted in Figs. 3 to 5, and only the resin front end portion 3 is shown.First, as shown in FIG. 3, the assembly of the resin front end portion 3 and the like is held and arranged such that the upper block portions 13 of the side support portions 10 on the left and right sides are located on the lower side of the front end portion 2 aof the front side member 2. Then, the assembly of the resin front end portion 3 and the like is raised to an upper part in an arrow direction to an upright position, and the inclined surface 13 aof the upper block portion 13 is brought into contact with the lower part of the front end portion 2 aof the front side member 2.In this state, by further raising the assembly of the resin front end portion 3 and the like along the inclined surface 13 aof the upper block portion 13, as shown in FIG. 4, the upper part of the assembly is guided by the inclined surface 13 aof the upper block portion 13 and inclined toward the vehicle front side. Thus, the assembly can be moved while avoiding interference with the peripheral components disposed in the periphery of the assembly. Moreover, at this time, since the left and right upper block portions 13 have different trapezoidal shapes, one of the left and right upper block portions 13 is selected considering positions in which the peripheral members are arranged, and the assembly is moved in the vehicle front-rear direction and in the left-right direction and in the vehicle vertical direction, or is moved in the rotational direction in a side view and a plan view to change the direction of the assembly.Subsequently, the upper part of the assembly is raised along the perpendicular surface 13 con the rear side of the upper block portion 13, and the intermediate fixing surface 15 cof the reinforcing bracket 15 is fitted to the surface of the front end portion 2 aof the front side member 2 and fastened to the front end portion 2 aof the front side member 2 with a bolt, so that as shown in FIG. 5, both left and right side support portions 10 are suspended from the front end portion 2 aof the front side member 2 by the reinforcing bracket 15, and the assembly such as the resin front end portion 3 is mounted to the vehicle body (see FIG. 2 ).In the structure of the resin front end portion 3 according to the embodiment of the present invention, since the upper block portions 13 having a trapezoidal shape in a vehicle side view protrude in the vehicle width direction on the side surfaces of the side support portions 10 on the left and right sides and constitute the frame structure, the rigidity of the side support portions 10 can be improved by the upper block portions 13. Moreover, the inclined surface 13 aextending diagonally downward toward the rear of the vehicle is formed on the upper end portion of the upper block portion 13, and since it is configured such that the inclined surface 13 aof the upper block portion 13 is brought into contact with the front end portion 2 aof the front side member 2 and the upper part of the assembly is moved toward the front of the vehicle when the assembly of the resin front end portion 3 and the like is to be mounted on the vehicle body, the upper block portion 13 performs the function of guiding the assembly, and the assembly can be raised while changing its direction to avoid interference with peripheral components in the engine room disposed in the periphery of the assembly.Therefore, according to the construction of the resin front end portion 3 of the embodiment, assembly of the assembly to the vehicle body in the production process can be performed quickly and reliably, and improvement in productivity and reduction in manufacturing cost can be achieved.The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention.For example, in the above-described embodiment, the fixing portion 16 and the first fixing portion 18 are configured as the same portion, and the reinforcing bracket 15 and the headlight 17 are joined to the vertical surface 13 bon the front side of the upper block portion 13 in the fixing portion 16 and the first fixing portion 18, but the fixing portion 16 and the first fixing portion 18 may also be separately provided, and the reinforcing bracket 15 and the headlight 17 may be fixed and fixed at separate locations.[List of Reference Numerals]1 Vehicle front 2 Front side member 2 a Front end portion 3 Resin front end portion 4 Heat exchanger 9 Upper member portion 9 a, 9 b Horizontal plane portion 10 Side support portion 11 Lower member portion 13 Upper block portion 13 a Schräge surface 15 Reinforcing bracket 15 a, 15 b, 15 c Surface 16 Mounting portion 17 Headlight 18 First mounting portion 19 Second mounting portion 20, 21 Support member S Space
