Description

  The present invention relates to a support structure for a cooling system component for supporting a cooling system component such as a radiator or an air conditioning capacitor in a front part of a vehicle body such as an automobile.

  In a vehicle such as an automobile, a cooling unit in which a radiator and an air conditioning condenser are integrated is disposed in the front part of the engine room. In the conventional support structure of the cooling unit, the locking projection protruding from the lower end of the radiator is inserted into the support hole of the lower cross member of the radiator support, and the upper end of the radiator is connected to the upper member of the radiator support via a bracket. It is supported with respect to the vehicle body. A bumper reinforcement of a front bumper is disposed in front of the cooling unit. The bumper reinforcement is provided so as to bridge the front ends of the left and right side members. At the time of a frontal collision of the vehicle, the bumper reinforcement is displaced backward and absorbs the impact.

  However, in the structure in which the upper and lower ends of the radiator are supported on the radiator support, which is a vehicle body structural member, such that they cannot be displaced as described above, the bumper reinforcement may interfere with the cooling unit and damage the cooling unit during a light vehicle collision. There is. As a countermeasure, if the distance (space) between the cooling unit and the bumper reinforcement along the vehicle front-rear direction is increased, the front overhang of the vehicle cannot be shortened.

  Therefore, a support structure for protecting the capacitor and the intercooler at the time of a collision has been considered (for example, see Patent Documents 1 to 3). In the support structure described in Patent Document 1, air guides are integrally attached to the left and right ends of the capacitor, and a pair of left and right rectangular pins protruding from the lower ends of the air guides are inserted into the rectangular holes of the lower panel of the vehicle body, respectively. At the same time, a pair of left and right circular pins projecting from the upper end of each air guide is inserted into a circular hole in the upper panel of the vehicle body, and the capacitor is sandwiched between the upper panel and the lower panel. The bumper reinforcement of the front bumper is inserted into a notch formed in the middle portion in the vertical direction of the flat plate portion that extends forward in each air guide and introduces air introduced from outside the vehicle to the condenser. Each rectangular pin and each circular pin are located on the inner side in the vehicle width direction from the flat plate portion, and each rectangular pin has a fragile structure.

In the event of a light vehicle collision, the impact load from the bumper reinforcement is input to the flat plate portion of the air guide, and each rectangular pin located on the inner side in the vehicle width direction than the flat plate portion of the air guide is twisted and broken. The lower end of is free to the car body. When the bumper reinforcement moves further rearward, the capacitor is held by the vehicle body via the circular pins of each air guide, and rotates with respect to the vehicle body with the imaginary straight line connecting the left and right circular pins as the axis and retracts backward. This prevents damage.

  By the way, the conventional capacitor support structure as described above has a configuration in which the bumper reinforcement is located in the center of the capacitor in the height direction, and therefore it is difficult to apply a large rotational moment to the capacitor due to the load from the bumper reinforcement. It was. Therefore, in this support structure, in order to enable the capacitor to be retracted backward by a load during a light collision, a rectangular pin that rotates around the vertical axis and breaks must be provided in the air guide. It was complicated and the flat part of the air guide had to have a structure capable of withstanding the load during the light collision. Although not described, in the configuration described in Patent Document 3, the capacitor is not released from the support state to the vehicle body during a light collision with the front bumper, and is not retracted and protected.

  In view of the above facts, an object of the present invention is to obtain a support structure for a cooling system component that can protect the cooling system component in a light collision without increasing the size of the vehicle body with a simple structure.

  In order to achieve the above object, a cooling system component support structure according to the first aspect of the present invention is a cooling system component support structure that supports a cooling system component disposed behind a skeleton member of a front bumper with respect to a vehicle body. A first support portion that supports a portion of the cooling system component positioned above or below the skeleton member so as to be rotatable about an axis along the vehicle width direction with respect to the vehicle body; and in the cooling system component A portion overlapping the rear of the skeleton member or a portion closer to the first support portion than the overlap portion and the vehicle body, and turning the cooling system component around the first support portion relative to the vehicle body And a second support part that is supported in an incapable manner and is released when a backward load of a predetermined value or more acts on the cooling system component from the skeleton member.

  In the cooling system component support structure according to claim 1, the cooling system component is normally supported by the first support portion so as to be allowed to rotate around the axis along the vehicle width direction, and the second support. The part is supported in a state in which the rotation is prevented. When the skeleton member of the front bumper comes into contact with the cooling system component due to the frontal collision of the vehicle and a backward load of a predetermined value or more is applied to the cooling system component, the support state of the cooling system component by the second holding part is released. . Thereafter, the cooling system component rotates around the first support portion with the rotational force input from the skeleton member. Thereby, if the predetermined value of the load for releasing the support state of the second support part is set smaller than the load that damages the cooling system component, the cooling system component is prevented from being damaged. For this reason, even if it arrange | positions so that a frame member and a cooling system component may interfere at the time of a light collision, a cooling system component will not be damaged, and the space | interval along the vehicle body front-back direction of this frame member and a cooling light component is set small. be able to.

  Here, since the second support portion is positioned on the rear side of the skeleton member in the cooling system component, or on the first support portion side with respect to the overlap portion, in other words, in the cooling system component, Since the second support portion is positioned closer to the center of rotation than the load input portion or the load input portion, the support state by the second support portion can be reliably released by a relatively small load during a light collision. Thereby, even if it is a simple structure in which a load is directly input from the skeleton member to the cooling system component, the cooling system component can be reliably protected during a light collision.

  As described above, the cooling system component support structure according to the first aspect of the present invention can protect the cooling system component in a light collision with a simple structure without increasing the size of the vehicle body. In addition, the skeleton member of the front bumper in the present invention is an independent skeleton member, for example, a strength member equivalent part integrated with a cover member or a cushion member (of which the horizontal member moves horizontally to the cooling system part. Abutting part). Further, the overlap portion in the present invention is a portion where the skeletal member in the cooling system component is projected in the horizontal direction (a portion that comes into contact with the skeleton member when it is relatively moved horizontally).

  The cooling system component supporting structure according to claim 2 is the cooling system component supporting structure according to claim 1, wherein the cooling system component has an upper end located behind the skeleton member and a lower end. Is supported by the first support portion with respect to the vehicle body.

  In the cooling system component support structure according to claim 2, the cooling system component whose lower end portion is rotatably supported by the first support portion with respect to the vehicle body has its upper end portion rearward by a skeleton member at the time of frontal collision of the vehicle. Pressed. For this reason, the length of the cooling system component from the first support portion to the load input site, that is, the arm of the moment for rotating the cooling system component around the first support portion is long, and is input from the skeleton member to the cooling system component. The support state by the second support portion can be released by a smaller load.

  A cooling system component support structure according to a third aspect of the present invention is the cooling system component support structure according to the second aspect, wherein the skeleton member is bridged between the front ends of the left and right side members constituting the vehicle body. The second support part supports the upper end of the cooling system component with respect to the side member.

  In the cooling system component support structure according to the third aspect, the second support portion is provided between the left and right side members having a skeleton member spanned at the tip and the upper end of the cooling system component. In other words, the second support portion is disposed in a portion overlapping the rear of the skeleton member, which is positioned farthest in the vertical direction from the first support portion in the cooling system component. For this reason, the arm of the moment which the 2nd support part generates in order to prevent rotation around the 1st support part of a cooling system part at the normal time also becomes long, and the 2nd support part has a side member and a cooling system part. Even when the holding force acting between the cooling parts is small, it is possible to reliably prevent the rotation of the cooling system parts around the first support part. Further, since the side member has high rigidity and has a small displacement (deformation amount) when a load is input from the skeleton member to the cooling system component, the reaction force when the second support portion releases the support state is improved. To support. For this reason, the second support portion reliably releases the support state when a load of a predetermined value or more is input from the skeleton member to the cooling system component. As described above, the second support portion can be configured with a small and simple structure.

  A cooling system component support structure according to a fourth aspect of the present invention is the cooling system component support structure according to the second or third aspect, wherein the upper end of the cooling system component is positioned forward of the lower end. Inclined.

  In the cooling system component support structure according to the fourth aspect, the cooling system component is inclined such that the upper end located behind the skeleton member is located forward of the lower end supported by the first support portion. This makes it possible to secure the rear space of the cooling system component by placing the upper end of the cooling system component close to the skeleton member, or to arrange the cooling system component having a relatively high height.

  A cooling system component support structure according to a fifth aspect of the present invention is the cooling system component support structure according to any one of the first to fourth aspects, wherein the second support portion is provided on the cooling system component. A holding portion provided, and a holding portion that is provided on the vehicle body and holds the held portion, and the holding portion and the holding portion are predetermined from the skeleton member to the cooling system component. It is configured to be detachable so as to be separated without being damaged when a backward load exceeding the value is applied.

  In the cooling system component support structure according to the fifth aspect, normally, the held portion is held (mounted) by the holding portion to prevent the cooling system component from rotating around the first support portion. When a backward load is input from the skeleton member to the cooling system component, the holding portion and the held portion are separated (separated) without being damaged. The cooling system component released from the support state by the second support portion rotates around the first support portion and is protected as described above. Here, since the holding portion and the held portion are separated without being damaged at the time of collision, they can be reused, and the repair cost is suppressed. In particular, it is not necessary to remove the cooling system parts from the vehicle body, which greatly reduces the repair cost.

  A cooling system component support structure according to a sixth aspect of the present invention is the cooling system component support structure according to the fifth aspect, wherein either the held portion or the holding portion is a pin member extending in the vehicle width direction. And the other of the held portion and the holding portion includes a receiving portion that holds the pin member in and holds, and a cutout portion that communicates with the receiving portion and opens in a separating direction from the pin member, It is an elastic holding member that separates the pin member in the housing part from the notch part while elastically deforming when a backward load of a predetermined value or more acts on the cooling system component from the skeleton member.

  In the cooling system component support structure according to the sixth aspect of the present invention, the rotation of the cooling system component around the first support portion is normally prevented by the pin member entering the accommodating portion of the elastic holding member. When a backward load is input from the skeleton member to the cooling system component, the elastic holding member is elastically deformed as the pin member engages with the elastic holding member so as to move relative to the elastic holding member, and the pin member in the elastic holding member The pin member passes through the notch opened in the separating direction. As described above, the second support portion has a simple structure including the pin member and the elastic holding member, and normally prevents the cooling system component from rotating and allows the cooling system component to rotate without being damaged at the time of collision. Function is realized.

  The cooling system component support structure according to claim 7 is the cooling system component support structure according to any one of claims 1 to 6, wherein the first support portion includes the cooling system component and the cooling system component. A shaft member provided on one of the vehicle bodies, and a bearing member provided on the other side of the cooling system component and the vehicle body and rotatably supporting the shaft member.

  The cooling system component support structure according to claim 7, wherein the first support portion includes a shaft member and a bearing member that rotatably supports the shaft member, and the cooling system component is arranged around the shaft member. It is pivotally supported. For this reason, the members provided between the vehicle body and the vehicle body itself do not undergo plastic deformation or breakage due to the rotation of the cooling system components during a light collision. In other words, it is possible to prevent the occurrence of a part or part that requires repair after a light collision.

  The cooling system component support structure according to an eighth aspect of the present invention is the cooling system component support structure according to any one of the first to sixth aspects, wherein the first support portion is the left and right front wheels of the vehicle. And a shaft support portion that is provided at the lower end portion of the cooling system component and is rotatably fitted to the stabilizer.

  In the cooling system component support structure according to claim 8, the first support portion is fitted to a shaft support portion provided at a lower end portion of the cooling system component so that the cooling system component is rotated around the stabilizer relative to the vehicle body. It is pivotally supported. For this reason, the members provided between the vehicle body and the vehicle body itself do not undergo plastic deformation or breakage due to the rotation of the cooling system components during a light collision. In other words, it is possible to prevent the occurrence of a part or part that requires repair after a light collision. In addition, suspension vibration can be suppressed using the mass of the cooling system components.

  As described above, the cooling system component support structure according to the present invention has a simple structure, and has an excellent effect that the cooling system component can be reliably protected in a light collision without increasing the size of the vehicle body.

  A cooling unit support structure 10, which is an example in which the cooling system component support structure according to the first embodiment of the present invention is applied to an automobile, will be described with reference to FIGS. 1 to 4. In the figure, the arrow FR indicates the front direction of the vehicle body, the arrow UP indicates the upward direction of the vehicle body, and the arrow IN indicates the vehicle width inside direction.

  FIG. 1 is a perspective view showing a schematic structure in an engine room constituting a front portion of an automobile body (hereinafter simply referred to as a vehicle body) S to which a cooling unit support structure 10 is applied. As shown in this figure, the vehicle body S includes a cooling unit 12 as a cooling system component. In the first embodiment, the cooling unit 12 includes a radiator 12A, an air conditioning condenser 12B disposed in front of the radiator 12A, and a fan unit 12C attached to the back side of the radiator 12A.

  In front of the cooling unit 12, a bumper reinforcement 16 as a skeleton member constituting the front bumper 14 is disposed. The bumper reinforcement 16 has a longitudinal shape in the vehicle width direction and is configured such that the left and right ends are curved (or bent) toward the rear. For this reason, as shown in FIGS. 2 and 3, the cooling unit 12 is closer to the bumper reinforcement 16 at both ends than at the center in the left-right direction.

  In the bumper reinforcement 16, the left and right side members 20, which are vehicle body skeleton members, are located in the vehicle width direction outer side than the cooling unit 12 (only one side member 20 is shown in each figure). Is fixed directly or via a crush box (not shown) or the like. That is, the bumper reinforcement 16 is spanned between the front ends of the left and right side members 20 and is located at the same height as the side members 20.

  As shown in FIG. 3, in the first embodiment, the bumper reinforcement 16 is positioned so as to overlap in front of the upper end of the cooling unit 12. Therefore, the left and right side members 20 are positioned so as to sandwich the upper end of the cooling unit 12. The bumper reinforcement 16 is covered with a front bumper cover 18 to form a front bumper 14. Further, as shown in this figure, the cooling unit 12 is substantially upright so that the positions of the upper end and the lower end of the cooling unit 12 substantially coincide with each other. The cooling unit 12 of the first embodiment is a type that has a relatively low height along the vertical direction.

  As shown by an imaginary line in FIG. 3, the cooling unit 12 is supported by the first support portion 22 so as to be rotatable about an axis along the vehicle width direction with respect to the vehicle body. Specifically, the first support portion 22 includes a pair of left and right shaft members 24 that are coaxially provided along the vehicle width direction from the vicinity of the lower ends of both left and right sides of the radiator 12A, and a lower skeleton member 26 of the vehicle body. And a pair of left and right bearing members 28 that rotatably support each shaft member 24. Thereby, the cooling unit 12 can be rotated around the axis of the shaft member 24 located in the vicinity of the lower end of the vehicle body. The lower skeleton member 26 of the vehicle body is, for example, a radiator support lower cross member, a well suspension member (well subframe), or the like.

  The cooling unit 12 is supported by the second support portion 30 with respect to the vehicle body, and is normally configured such that the rotation of the shaft member 24 (first support portion 22) about the axis is restricted. Specifically, the second support portion 30 includes a pair of left and right mounting pins 32 as a holding portion or a held portion protruding from the left and right side members 20 along the vehicle width direction, and both left and right sides of the radiator 12A. It comprises a pair of left and right bush members 34 provided in the vicinity of the upper end of the part and allowing the attachment pins 32 to enter.

  As shown in FIG. 4A, the bush member 34 has an accommodating portion 34A in which the inner diameter substantially corresponds to the outer diameter of the mounting pin 32 and allows the mounting pin 32 to enter, and a pin detachment notch portion 34B communicating with the accommodating portion. In the first embodiment, it is formed in a substantially C shape that opens forward as a whole. The bush member 34 is made of an elastic material such as rubber or resin so that the opening width of the notch portion 34 </ b> B for pin separation is slightly smaller than the outer diameter of the mounting pin 32. Thereby, the 2nd support part 30 is set as the structure which controls the rotation around the said shaft member 24 of the cooling unit 12 by making the attachment pin 32 enter in the accommodating part 34A of the bush member 34 normally. .

  On the other hand, the second support portion 30 has a notch for pin detachment due to the relative displacement of the bushing member 34 with the mounting pin 32 engaged with the inner surface of the accommodating portion 34A when a load of a predetermined value or more in the rearward direction acts on the cooling unit 12. The portion 34B is elastically deformed so as to expand, and is detached from the mounting pin 32 as shown in FIG. 4 (B). That is, the bush member 34 and the mounting pin 32 are separated from each other without suffering damage such as breakage or breakage by a backward load (a moment around the shaft member 24 based on a predetermined value or more) acting on the cooling unit 12. It is configured to be removable (reusable). The predetermined value of the load is set as a load that causes no problem in strength of the cooling unit 12 (does not cause breakage).

  Next, the operation of the first embodiment will be described.

  In the automobile to which the cooling unit support structure 10 having the above-described configuration is applied, the normal cooling unit 12 is supported by the first support portion 22 and the second support portion 30 without being displaced with respect to the vehicle body S. For example, cooling of engine coolant or air conditioner refrigerant is performed.

  When a collision object C (see FIG. 2) collides lightly from the front with respect to the front bumper 14 of the vehicle (light collision), the bumper reinforcement 16 is deformed and moves rearward, and the cooling unit 12 contacts the cooling unit 12 while cooling. The unit 12 is pushed backward. At this time, if the backward load acting on the cooling unit 12 is equal to or greater than a predetermined value, the bush member 34 on the cooling unit 12 side is deformed and the second support portion 30 is separated from the mounting pin 32 on the vehicle body S side.

Then, the cooling unit 12 is in a state of being rotatable around the shaft member 24 of the first support portion 22, and is rotated rearward around the shaft member 24 using the load input from the bumper reinforcement 16 as rotational force. That is, the cooling unit 12 is retracted backward. As a result, the cooling unit 12 is protected against impact without applying a load exceeding the predetermined value (actual load when the bush member 34 is separated from the mounting pin 32) due to the collision.
Thus, even if the cooling unit 12 is arranged so that the bumper reinforcement 16 interferes at the time of a light collision, the cooling unit 12 is protected. Therefore, it is possible to reduce the front overhang by reducing these intervals. .

  Here, since the 2nd support part 30 is provided between the vehicle body and the part which overlaps the back of the bumper reinforcement 16 frame | skeleton member in the cooling unit 12, in other words, the backward load in the cooling unit 12 Since the second support part 30 is located at the input part, the support state by the second support part 30 is reliably released by a small load compared to the conventional structure in which a load is input between the upper and lower support parts of the capacitor. can do.

  In particular, the cooling unit 12 is configured such that the vicinity of the lower end thereof is rotatably supported by the first support portion 22 and a load is input from the bumper reinforcement 16 to the upper end thereof. The moment arm for rotating around the member 24 is long. For this reason, the support state by the 2nd support part 30 can be cancelled | released by the still smaller load input into the cooling unit 12 from the bumper reinforcement 16. FIG.

  Further, the side member 20 that supports the upper end of the cooling unit 12 via the second support portion 30 has high rigidity (has sufficient rigidity for a light collision level load), and the bumper reinforcement 16 changes to the cooling unit 12. Since the displacement (deformation amount) when the load is input is small, the second support portion 30 favorably supports the reaction force when the support state is released (the mounting pin 32 and the bush member 34 are separated). For this reason, the second support portion 30 supports the bumper reinforcement 16 when a load exceeding a predetermined value (simply a load required to separate the mounting pin 32 and the bush member 34) is input from the bumper reinforcement 16 to the cooling unit 12. Release the state securely.

  As described above, even with a simple configuration in which a load is directly input from the bumper reinforcement 16 to the cooling unit 12, the cooling unit 12 can be reliably protected during a light collision. That is, the cooling unit 12 is reliably protected against a light collision by a simple structure that does not require the provision of an air guide having a rectangular pin or the like, or the rigid construction of the flat portion of the air guide. be able to. Further, the configuration in which the bumper reinforcement 16 directly presses the cooling unit 12 allows the cooling unit to be applied even in a collision mode in which a load is locally input in the longitudinal direction of the bumper reinforcement 16 such as a pole collision. 12, the support state by the second support portion 30 is reliably released and the shaft 12 rotates around the shaft member 24 and is protected as described above.

  As described above, the cooling unit support structure 10 according to the present embodiment has a simple structure, and can reliably protect the cooling unit 12 during a light collision without increasing the size of the vehicle body.

  Further, since the second support portion 30 is provided between the upper end of the cooling unit 12 and the side member 20, the second support portion 30 prevents the rotation of the cooling unit 12 around the shaft member 24 at the normal time. The moment arm is long. For this reason, even if the holding force to be applied between the side member 20 and the cooling unit 12 (the mounting pin 32 and the bushing member 34) is small, the second support portion 30 normally has the shaft member 24 of the cooling unit 12. The rotation of the surroundings can be reliably prevented. Thereby, in the support structure 10 of this cooling unit, the small and simple structure which comprises the 2nd support part 30 with the attachment pin 32 and the bush member 34 is implement | achieved.

  That is, since the second support portion 30 is configured by the mounting pin 32 and the elastically deformable bush member 34 having the accommodating portion 34A for inserting the mounting pin 32 and the notch portion 34B for pin detachment, the second support portion 30 is a simple structure that normally prevents the cooling unit 12 from rotating, separates during a light collision, allows the cooling unit 12 to rotate, and implements each function of returning to the mounted state again after a light collision. is doing. This reduces the repair cost after a light collision. In particular, the configuration that allows the second support portion 30 to be reused eliminates the need to remove the cooling unit 12 from the vehicle body at the time of repair, which greatly reduces the repair cost.

(Second Embodiment)
Next, the support structure 50 of the cooling unit 12 according to the second embodiment of the present invention will be described with reference to FIG. Note that parts and portions that are basically the same as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.

  As shown in FIG. 5, the support structure 50 of the cooling unit 12 is different from the first embodiment in which the cooling unit 12 is supported in a substantially upright state in that the cooling unit 12 is supported in a forwardly inclined state. Specifically, the cooling unit 12 has its upper end arranged by disposing the attachment position of the attachment pin 32 constituting the second support portion 30 in the side member 20 ahead of the same position in the first embodiment. Is supported in a forward leaning position located forward of the lower end. Therefore, the cooling unit 12 is located closer to the back surface of the bumper reinforcement 16. Other configurations of the support structure 50 of the cooling unit 12 are the same as those of the support structure 10 of the cooling unit according to the first embodiment.

  In the support structure 50 of the present cooling unit 12, by tilting the cooling unit 12 forward as described above, for example, a large space is secured behind the cooling unit 12 to increase the degree of freedom of component layout, There are advantages in that it is possible to reduce the discharge resistance of the air that has passed through and to mount a relatively tall cooling unit 12.

  And since this cooling unit 12 is supported with respect to the vehicle body S by the 1st support part 22 and the 2nd support part 30, the upper end of the cooling unit 12 adjoins to the back surface of the bumper reinforcement 16 as mentioned above. Also in the configuration, similarly to the first embodiment, the cooling unit 12 can be reliably protected during a light collision. In other words, the cooling system component support structure according to the present invention is favorably applied to a configuration in which the cooling unit 12 is tilted forward to obtain the above-described merits.

(Third embodiment)
Next, a support structure 60 for the cooling unit 12 according to a third embodiment of the present invention will be described with reference to FIGS. 6 and 7. Note that parts and portions that are basically the same as those in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.

  As shown in FIG. 6, the support structure 60 of the cooling unit 12 is such that the lower end of the cooling unit 12 is supported by a stabilizer 62 that constitutes the front suspension, and the lower end of the cooling unit 12 is interposed via the first support portion 22. This is different from the first and second embodiments in which the lower skeleton member 26 of the vehicle body S is used. This will be specifically described below.

  The stabilizer 62 includes a twisted portion 62A whose longitudinal direction substantially coincides with the vehicle width direction, and a pair of left and right connecting portions 62B extending substantially rearward from both the left and right sides of the twisted portion 62A. It is formed in a substantially U-shape that opens backward. The distal ends of the connecting portions 62B are connected to the corresponding lower arms (left and right wheels) 64, respectively. Further, the vicinity of the end portion of the twisted portion 62 </ b> A formed in a solid cylindrical shape is supported by a suspension member (subframe) 68 formed in a substantially well shape via a support member 66. Thus, the stabilizer 62 is configured to improve the roll rigidity by twisting the torsion part 62A and generating a reaction force when the left and right wheels move in opposite phases.

  As shown in FIG. 7, the cooling unit 12 is supported by the first support portion 70 so as to be pivotable backward with respect to the vehicle body. Specifically, the first support portion 70 includes a twisted portion 62 </ b> A of the stabilizer 62 and a shaft support portion 72 that protrudes from the lower end of the cooling unit 12. In the third embodiment, one shaft support portion 72 is provided near each of the left and right ends of the cooling unit 12. Each shaft support portion 72 has a pair of front and rear support pieces 74 each having an arcuate guide surface 74A that follows the outer peripheral surface of the stabilizer 62, and is formed in a substantially C-shape that opens downward as a whole.

  Each support piece 74 is elastically deformable so as to expand and contract the interval between the opening ends of each support piece 74, and is configured to be attached to the stabilizer 62 by pressing the opening end against the twisted portion 62A of the stabilizer 62 from above. is there. As a result, the cooling unit 12 is pivotally supported so as to be able to rotate freely with respect to the stabilizer 62 (with respect to the vehicle body) without hindering the elastic torsional deformation of the twisted portion 62A of the stabilizer 62.

  Although not shown, the upper end of the cooling unit 12 is positioned so as to overlap the rear of the bumper reinforcement 16 and is supported by the side member 20 via the second support portion 30. Or it is the same as that of 2nd Embodiment. The cooling unit 12 may be supported in a substantially upright state as in the first embodiment, or may be supported in a forwardly inclined state as in the second embodiment.

  The support structure 60 of the cooling unit 12 has the following effects in addition to the same effects as those of the first or second embodiment.

You may be located in the 1st support part 22 side rather than the overlap part with the bumper reinforcement in the unit 12. FIG. Therefore, for example, the second support portion 30 may be provided between the radiator support side or the like and the left and right side portions of the radiator 12A, and the second support portion 30 may be provided around the shaft member 24. Further, the second support portion 30 is not limited to the configuration composed of the mounting pin 32 and the bush member 34, and various configurations can be adopted, and the second support portion 30 is broken when a load exceeding a predetermined value is input to the cooling unit 12. The supporting state may be released. Even in such a configuration that breaks, for example, by providing the second support portion 30 between the side member 20 and the side surface of the radiator 12A, the cooling unit 12 does not need to be removed from the vehicle body S for repair. Is possible. Needless to say, the second support portion 30 may be configured by providing the bush member 34 on the side member 20 and providing the attachment pin 32 on the radiator 12A.

  Furthermore, in each said embodiment, the cooling unit 12 is the structure supported so that rotation with respect to the vehicle body S is possible by the 1st support part 22 or the stabilizer 62 which consists of the shaft member 24 and the bearing member 28, and the shaft support part 70. However, the present invention is not limited to this, and various structures that support the cooling unit 12 so as to be rotatable with respect to the vehicle body can be employed. Therefore, for example, a structure in which a shaft member attached to the lower skeleton member 26 of the vehicle body S is rotatably inserted into a hole provided in the side wall of the radiator 12A, or a restoring force or attenuation is accompanied with the rotation of the cooling unit 12. A configuration that generates a reaction force such as force can be employed.

  Furthermore, in each said embodiment, although the front bumper 14 showed the example comprised by the bumper reinforcement 16 and the bumper cover 18, this invention is not limited to this, The book is a vehicle to which a name is applied. Any type of front bumper having a member (part) grasped as a skeleton member may be provided.
