Description

  The present invention relates to a vehicle body front structure of an automobile, and more particularly to a structure of a damper rubber and a seat surface that receive a load when a hood is closed.

  The hood that covers the engine room of the automobile is pivoted so that the rear end is fixed to the vehicle body and the front side moves in the vertical direction to open and close the engine room. A damper rubber that absorbs the load (load, energy) of the hood when the hood is closed is placed on the front side of the engine room of the car body. It is done. Alternatively, the damper rubber may be provided on the hood side and the seat surface may be provided on the vehicle body side. The damper rubber and the seating surface are provided so that the opposing surfaces are parallel to each other when the hood is closed (stationary state), so that the entire load can be received when the hood is closed.

  By the way, hoods in recent years are formed so as to absorb the external force when an external force is applied and relax the force received by the pedestrian, assuming the contact with the pedestrian. For example, there are those in which the rigidity of the hood is suppressed to the minimum necessary so that it can be easily deformed by an external force, and those in which the hood is actively deformed when an external force is applied (for example, see Patent Documents 1 and 2). ).

JP 2011-240815 A JP 2008-74158 A

  However, in the case of a vehicle body having a hood with low rigidity as described above, the hood will bend if a large load is applied during closing, such as when the hood is dropped from a high position and closed. There is. In this case, the opposing surfaces of the damper rubber and the seating surface do not hit in parallel when the hood is closed, and often hit a limited range in front of or behind the vehicle. As described above, when the damper rubber and the seat surface are in contact with each other (front of the vehicle or rear of the vehicle) when the hood is closed, the load concentrates on the portion and the seat surface is deformed, resulting in deterioration of appearance. That is, there is a demand for a structure that can prevent deformation of the seat surface when the hood is closed even if the rigidity of the hood is kept low.

  The present invention has been devised in view of the above problems, and an object of the present invention is to provide a vehicle body front structure that can suppress deformation of the seat surface when the hood is closed. The present invention is not limited to this purpose, and is a function and effect derived from each configuration shown in the embodiments for carrying out the invention described later, and other effects of the present invention are to obtain a function and effect that cannot be obtained by conventional techniques. Can be positioned.

(1) A vehicle body front part structure disclosed herein is provided so as to cover an opening at an upper part on the front side of the vehicle body from above, and a hood capable of opening and closing the opening around a rotation shaft extending in the vehicle width direction at the rear part of the opening. And a damper rubber that is fixed to one of the front lower surface of the hood and the front upper surface of the opening of the vehicle body and absorbs a load when the hood is closed, and is formed on one of the front lower surface and the front upper surface And a seat surface that contacts the damper rubber when the hood is closed. Furthermore, the seat surface, have a bead portion that is recessed and extends linearly in the longitudinal direction of the vehicle, one of said seat surface upper or lower surface and the seat surface opposed to one of the damper rubber has wherein Ru is provided as an inclined surface which is inclined to the vehicle front or vehicle rear upper or lower surface and in the closed state of the hood relative to the other of said seat surface.

(2) It is preferable that the vehicle front-rear direction length of the bead part is longer than the vehicle front-rear direction length of the upper surface or the lower surface of the damper rubber facing the seat surface.
(3) It is preferable that one bead portion is provided at the center of the seat surface in the vehicle width direction .

( 4 ) It is preferable that the seat surface is provided as the inclined surface portion.
( 5 ) It is preferable that the seat surface protrudes or is recessed from the front lower surface or the front upper surface. That is, it is preferable that the seating surface has a step in the plate thickness direction (thickness direction).

According to the disclosed vehicle body front part structure, since the seat surface that receives the damper rubber has the bead portion that extends in the vehicle front-rear direction and is recessed, the rigidity of the seat surface can be increased. Moreover, even if a load concentrates on the vehicle front or rear range of the seat surface when the hood is closed, the range in which the load is concentrated can be reduced by the bead portion. Furthermore, since either the upper surface or the lower surface of the damper rubber facing the seat surface or the seat surface is provided as an inclined surface portion inclined toward the front or rear of the vehicle with the hood closed, the hood is strongly closed. When this occurs, the upper surface or lower surface of the damper rubber and the seating surface come into surface contact with each other over a wide surface. By these, the deformation | transformation of the seat surface at the time of hood closure can be suppressed, and appearance (designability) can be improved.

[1. Constitution]
The vehicle body front structure according to the present embodiment will be described with reference to FIGS. 1A and 1B are longitudinal sectional views passing through a damper rubber 10 at the front of the vehicle body, where FIG. 1A shows a closed state (stationary state) of the hood, and FIG. The state at the time of closing (the moment of closing) is shown. 2 (a) and 2 (b) are modified examples corresponding to the states of FIGS. 1 (a) and 1 (b), respectively, in which the main part is simplified, and FIG. It is a figure when seeing from the front. In FIG. 2C, the upper surface 10a of the damper rubber 10 that contacts the seating surface 33 is indicated by a two-dot chain line. FIG. 3 is a side view of a vehicle to which the vehicle body front structure is applied.

  As shown in FIG. 3, the vehicle body front structure of the present embodiment includes a hood 3 provided so as to cover the opening 2 in the vehicle body front upper portion of the vehicle 1 from above. The opening 2 is an opening opened above an engine room (not shown) located on the front side of the vehicle body. The engine room has left and right front inside panels that extend in the vehicle longitudinal direction on both sides in the vehicle width direction (left and right direction), and a front cross bar (front cross member) that is disposed at the front end of the vehicle and extends in the vehicle width direction. And a space surrounded by a dash panel extending in the vehicle width direction behind the front crossbar.

  As shown in FIG. 3, the hood 3 forms the upper surface of the vehicle body from between the headlights 4 provided on the left and right of the front end of the vehicle body to the rear of the vehicle (hereinafter referred to as the rear). The hood 3 has a rotating shaft C extending in the vehicle width direction at the rear portion (the rear portion of the opening 2), and the front side moves up and down around the rotating shaft C to open and close the opening 2. The rotation axis C is a virtual axis that serves as a rotation center when the hood 3 is opened and closed. For example, the hood 3 is provided via a hinge (not shown) provided at the left and right rear ends (base ends). When fixed to the vehicle body, it corresponds to an imaginary line connecting the axial centers of the left and right hinges.

  A front bumper 5 for absorbing an impact from the front of the vehicle (hereinafter referred to as the front) is provided below the hood 3 and the headlight 4. As shown in FIGS. 1A and 1B, the upper end portion of the front bumper 5 is attached to the front upper surface 6 (for example, the upper surface of the front bar) of the opening 2 of the vehicle body. The front upper surface 6 corresponds to the upper surface of the front part of the frame (opening frame) of the opening 2. A damper rubber 10 that absorbs a load (load, energy) when the hood 3 is closed is fixed to the front upper surface 6.

  The damper rubber 10 is a substantially cylindrical rubber member (elastic body), and is fixed at a plurality of locations (for example, at two locations) at intervals in the vehicle width direction. The damper rubber 10 of the present embodiment is fixed in such a direction that its axis is inclined forward with respect to the vertical direction. The upper surface 10 a of the damper rubber 10 is a circular flat surface, and the normal line extends upward and forward, and is formed so as to be parallel to the axis of the damper rubber 10.

  The hood 3 includes an outer panel 31 that is formed in a curved downward slope toward the front and forms the outer surface of the vehicle 1, and a reinforcing inner panel 32 that is provided on the inner side (lower side) of the outer panel 31. . The inner panel 32 is provided along the outer panel 31 while forming a space between the inner panel 31 and is joined to the outer panel 31 at an outer peripheral edge portion thereof. A bulging portion 32 a that bulges in a direction away from the outer panel 31 is provided at the front end portion of the inner panel 32. The bulging portion 32a is a portion that is curved so that the space between the outer panel 31 and the outer panel 31 is larger than the other portion, and extends in the vehicle width direction.

  The hood 3 has a seat surface 33 on the front lower surface 3b that comes into contact with the damper rubber 10 (receives the damper rubber 10) when the hood 3 is closed. The seat surface 33 and the upper surface 10a of the damper rubber 10 are opposed surfaces that face each other. As shown in FIGS. 1A and 1B, the seat surface 33 of the present embodiment is recessed in a surface (front lower surface 3 b) facing the bulging portion 32 a of the inner panel 32 (on the outer panel 31 side). Projecting). Similar to the damper rubber 10, the seat surface 33 is provided at a plurality of locations (as many as the number of the damper rubbers 10) at intervals in the vehicle width direction. The seat surface 33 is formed in a size having a margin with respect to the upper surface 10a so that the entire upper surface 10a of the damper rubber 10 can be received.

  In addition, the seat surface 33 is not restricted to what was recessedly provided as shown to Fig.1 (a) and (b). For example, as shown in FIGS. 2A and 2B, the seat surface 33 may protrude from the front lower surface 3 b of the hood 3 toward the damper rubber 10. That is, it is preferable that the seat surface 33 that receives the damper rubber 10 protrudes or is recessed (has a step in the thickness direction) from the surface (the front lower surface 3b) on which the seat surface 33 is provided.

  As shown in FIGS. 2A to 2C, the seat surface 33 has a bead portion 34 that extends linearly in the vehicle front-rear direction and is recessed. One bead portion 34 of the present embodiment is provided in the center of the seat surface 33 in the vehicle width direction, and is formed in an oval shape having a vehicle longitudinal direction length B. The bead portion 34 is formed such that the vehicle longitudinal direction length B is longer than the vehicle longitudinal direction length D of the upper surface 10 a of the damper rubber 10 and shorter than the vehicle longitudinal direction length S of the seat surface 33.

  The rear end portion (base end portion) of the hood 3 is provided with a biasing means (not shown) that constantly biases the hood 3 in the opening direction. A lock mechanism (not shown) that maintains the closed state of the hood 3 (locks the hood 3) is provided on the hood 3 and the vehicle body side. The lock mechanism includes, for example, a striker provided at the center in the vehicle width direction of the front lower surface 3b of the hood 3 and a latch provided at a position corresponding to the striker on the vehicle body side. The hood 3 is always urged in the opening direction by the urging means, but when the hood 3 is locked by the lock mechanism, the closed state is maintained. In this closed state, even if the seat surface 33 and the upper surface 10 a of the damper rubber 10 come into contact with each other, the load of the hood 3 is not applied to the damper rubber 10 via the seat surface 33. The damper rubber 10 and the seating surface 33 are provided on both sides of the lock mechanism, for example.

  Both the outer panel 31 and the inner panel 32 have a small thickness so that the hood 3 can effectively absorb the external force (impact) applied to the hood 3 in consideration of contact with a pedestrian (during collision). Formed, and its rigidity is low (minimum necessary). In addition, the inner panel 32 may have a hole for suppressing weight and rigidity. For this reason, when the hood 3 is strongly closed, such as when it is dropped from a high position and closed, the hood 3 may be subjected to a large load and may be bent at the front end.

  Therefore, in the vehicle body front portion structure of the present embodiment, as shown in FIGS. 1A and 2A, the seat surface 33 of the hood 3 is in a closed state of the hood 3 with respect to the upper surface 10 a of the damper rubber 10. It is provided as an inclined surface portion 33c inclined rearward of the vehicle. That is, in the closed state of the hood 3, the normal line of the inclined surface portion 33 c (seat surface 33) and the normal line of the upper surface 10 a of the damper rubber 10 are not parallel, and the inclined surface portion 33 c is inclined with respect to the upper surface 10 a of the damper rubber 10. Is provided.

  Hereinafter, when the direction of the inclination formed on the facing surface between the hood 3 and the damper rubber 10 is described, it is the front or the rear that is positioned below with the surface facing the inclined surface viewed horizontally. Express what it is. For example, as shown in FIG. 2A, the inclined surface portion 33c is arranged in a posture inclined downward toward the rear of the vehicle. Thereby, a wedge-shaped gap 7 is formed between the inclined surface portion 33 c and the upper surface 10 a of the damper rubber 10. The gap 7 of the present embodiment is a wedge-shaped space that is wide on the front side and narrows toward the rear, and is formed uniformly in the vehicle width direction.

  The inclination angle and the inclination direction of the inclined surface portion 33c with respect to the upper surface 10a are set in consideration of instantaneous deflection of the hood 3 that may occur when the hood 3 is closed. Specifically, as shown in FIG. 1B and FIG. 2B, the upper surface 10a of the damper rubber 10 is set so that the surfaces (the upper surface 10a and the seating surface 33) that face each other when the hood 3 is closed are parallel to each other. An inclination angle with respect to is set. Further, the direction in which the inclined surface portion 33c is inclined (whether it is inclined downward toward the front of the vehicle or inclined downward toward the rear of the vehicle) is also set in consideration of the instantaneous deflection that occurs when the hood 3 is closed. .

[2. Action, effect]
When the hood 3 is closed, where the load of the hood 3 acts on the seat surface 33, a vertical force acts on the damper rubber 10 and the seat surface 33. This is because the hood 3 rotates about the rear rotation axis C so that the front side moves in the vertical direction. When the hood 3 bends at the time of closing, the damper rubber 10 and the seating surface 33 do not face each other (the upper surface 10a and the seating surface 33) in parallel but hit a limited range in front of or behind the vehicle. There are many cases. As described above, when the damper rubber 10 and the seating surface 33 come into contact with a part (the vehicle front or the vehicle rear) when the hood 3 is closed, a load acts on the part and the seating surface 33 can be deformed. There is sex.

  On the other hand, in the vehicle body front structure described above, the seat surface 33 that receives the damper rubber 10 is provided with a bead portion 34 that extends in a linear manner in the vehicle front-rear direction, and thus the rigidity of the seat surface 33 is increased. In addition, the load concentration range can be reduced. Thereby, a deformation | transformation of the seat surface 33 at the time of closure of the food | hood 3 can be suppressed, and appearance (designability) can be improved.

  Further, in the vehicle body front portion structure described above, the vehicle longitudinal direction length B of the bead portion 34 is formed longer than the vehicle longitudinal direction length D of the upper surface 10 a of the damper rubber 10. That is, since the bead portion 34 is provided so as to cross the upper surface 10 a of the damper rubber 10 that hits the seat surface 33, the rigidity of the seat surface 33 can be increased and deformation of the seat surface 33 can be further suppressed.

  Moreover, since the seat surface 33 is formed in the size which can receive the upper surface 10a of the damper rubber 10, there exists a subject that the space which provides the bead part 34 is small (space restrictions are large). On the other hand, in the vehicle body front part structure described above, since one bead portion 34 is provided at the center in the vehicle width direction of the seating surface 33, it is easy to secure the vehicle front-rear direction length B of the bead portion 34, and space constraints are also imposed. Can respond.

  In the vehicle body front structure described above, the seat surface 33 of the hood 3 is provided as an inclined surface portion 33c that is inclined rearward of the vehicle with the hood 3 closed with respect to the upper surface 10a of the damper rubber 10. Therefore, when the hood 3 is strongly closed, the upper surface 10a of the damper rubber 10 and the seating surface 33 are in surface contact with each other on a wide surface when the hood 3 is closed, as shown in FIGS. It will be.

  On the other hand, when the hood 3 is closed gently, as shown in FIGS. 1A and 2A, when the hood 3 is closed, a part of the upper surface 10a of the damper rubber 10 and the seat surface 33 come into contact with each other. Will do. However, in this case, since the load acting on the seating surface 33 is small, even if the upper surface 10a of the damper rubber 10 and the seating surface 33 are partially in contact with each other, it is unlikely that the seating surface 33 is deformed. Further, in the closed state of the hood 3, as shown in FIGS. 1A and 2A, even if a part of the upper surface 10a of the damper rubber 10 and the seat surface 33 are in contact with each other, the urging means Since the load of the hood 3 acting on the seating surface 33 is made small by the lock mechanism, the seating surface 33 is hardly deformed.

  Thus, in the above-described vehicle body front structure, the seat surface 33 is provided as the inclined surface portion 33c. Therefore, when the hood 3 is closed tightly (when the load of the hood 3 acts on the seat surface 33 greatly). The upper surface 10a of the damper rubber 10 and the seating surface 33 come into contact with each other on a wide surface. Thereby, the load at the time of closing of the food | hood 3 can be disperse | distributed to the whole surface. Therefore, by suppressing the rigidity of the hood 3 to a low level, even if bending occurs when the hood 3 is closed, load concentration acting on the seat surface 33 when the hood 3 is closed is prevented, and deformation of the seat surface 33 is further suppressed. Can be improved and appearance (designability) can be improved.

  Further, the hood 3 is formed by pressing a sheet metal or the like, and the seat surface 33 is integrally formed when the hood 3 is formed. In the vehicle body front structure described above, the seat surface 33 is provided as the inclined surface portion 33c. Therefore, it is only necessary to add a device for tilting the seat surface 33 forward or rearward of the vehicle by a predetermined angle to the conventional molding process. For this reason, it is possible to easily process the inclined surface portion 33c while suppressing an increase in processing cost and processing man-hours.

  Further, in the vehicle body front structure described above, since the seat surface 33 protrudes or is recessed from the front lower surface 3b of the hood 3, the rigidity of the seat surface 33 can be increased, and deformation of the seat surface 33 is further suppressed. be able to.

The seat surface 63 and the lower surface 10b of the damper rubber 10 are opposed surfaces that face each other. The seat surface 63 is provided with one bead portion 64 extending linearly in the vehicle front-rear direction and recessed at the center in the vehicle width direction. The bead portion 64 is formed such that the length in the vehicle front-rear direction is longer than the length in the vehicle front-rear direction of the lower surface 10 b of the damper rubber 10, similar to the bead portion 34 described above.

  In this modification, the seat surface 63 is provided as an inclined surface portion 63c that is inclined downward toward the front of the vehicle with the hood 3 closed with respect to the lower surface 10b of the damper rubber 10. That is, in the closed state of the hood 3, as shown in FIG. 4A, the normal line of the inclined surface part 63c (seat surface 63) and the normal line of the lower surface 10b of the damper rubber 10 are not parallel, and the inclined surface part 63c. Is provided obliquely with respect to the lower surface 10 b of the damper rubber 10. As a result, a wedge-shaped gap 7 similar to that described above is formed between the inclined surface portion 63 c and the lower surface 10 b of the damper rubber 10.

  The inclination angle and the inclination direction with respect to the lower surface 10b of the inclined surface portion 63c are set in consideration of the instantaneous deflection of the hood 3 that may occur when the hood 3 is closed, as in the above-described embodiment. Specifically, as shown in FIG. 4B, the inclination angle with respect to the lower surface 10b of the damper rubber 10 is set so that the surfaces (the lower surface 10b and the seat surface 63) facing each other when the hood 3 is closed are parallel to each other. The Further, the direction in which the inclined surface portion 63c is inclined (whether it is downwardly inclined toward the front of the vehicle or downwardly inclined toward the rear of the vehicle) is also set in consideration of instantaneous deflection that occurs when the hood 3 is closed. .

  Therefore, also in the vehicle body front portion structure of the present modification, the rigidity of the seat surface 63 can be increased by the bead portion 64 and the load concentration range can be reduced similarly to the above-described embodiment, and the same as described above. The effect of can be obtained. Further, when the hood 3 is strongly closed (when the load of the hood 3 acts on the seat surface 63 greatly), the lower surface 10b of the damper rubber 10 and the seat surface 63 come into contact with each other on a wide surface. Thereby, the load at the time of closing of the hood 3 can be disperse | distributed to the whole surface, and the effect similar to the above-mentioned embodiment can be acquired.

[3-2. Second modification]
As shown in FIGS. 5A and 5B, the vehicle body front structure according to the second modification is similar to the above embodiment in that the damper rubber 10 is fixed to the front upper surface 6 of the opening 2 of the vehicle body, 33 is formed on the front lower surface 3b of the hood 3 and protrudes from the front lower surface 3b to the damper rubber 10 side. The seat surface 33 and the upper surface 10a of the damper rubber 10 are opposed surfaces that face each other. Similarly to the above-described embodiment, the seat surface 33 is provided with one bead portion 34 that extends linearly in the vehicle front-rear direction and is recessed at the center in the vehicle width direction.

  In the present modification, the upper surface 10 a of the damper rubber 10 is provided as an inclined surface portion 10 c that is inclined downward toward the front of the vehicle with the hood 3 closed with respect to the seat surface 33. That is, in the closed state of the hood 3, as shown in FIG. 5A, the normal line of the inclined surface portion 10c (the upper surface 10a of the damper rubber 10) and the normal line of the seat surface 33 are not parallel, and the inclined surface portion 10c. Is provided obliquely with respect to the seating surface 33. As a result, a wedge-shaped gap 7 similar to that described above is formed between the inclined surface portion 10 c and the seat surface 33.

  The inclination angle and the inclination direction of the inclined surface portion 10c with respect to the seating surface 33 are set in consideration of the instantaneous deflection of the hood 3 that may occur when the hood 3 is closed, as in the above-described embodiment. Specifically, as illustrated in FIG. 5B, the inclination angle with respect to the seating surface 33 is set so that the surfaces (the upper surface 10 a and the seating surface 33) that face each other when the hood 3 is closed are parallel to each other. Further, the direction in which the inclined surface portion 10c is inclined (whether it is downwardly inclined toward the front of the vehicle or downwardly inclined toward the rear of the vehicle) is also set in consideration of the instantaneous deflection that occurs when the hood 3 is closed. .

  Therefore, also in the vehicle body front part structure of the present modification, as in the above-described embodiment, the rigidity of the seat surface 33 can be increased by the bead portion 34 and the load concentration range can be reduced. The effect of can be obtained. Further, when the hood 3 is strongly closed (when a large load of the hood 3 acts on the seat surface 33), the upper surface 10a of the damper rubber 10 and the seat surface 33 come into contact with each other on a wide surface. Thereby, the load at the time of closing of the hood 3 can be disperse | distributed to the whole surface, and the effect similar to the above-mentioned embodiment can be acquired.

[3-3. Third modification]
As shown in FIGS. 6A and 6B, in the vehicle body front portion structure according to the third modified example, the damper rubber 10 is fixed to the front lower surface 3b of the hood 3 in the same manner as in the first modified example. Is formed on the front upper surface 6 of the opening 2 of the vehicle body and protrudes from the front upper surface 6 toward the damper rubber 10. The seat surface 63 and the lower surface 10b of the damper rubber 10 are opposed surfaces that face each other. As in the first modification, the seat surface 63 is provided with one bead portion 64 that extends linearly in the vehicle front-rear direction and is recessed at the center in the vehicle width direction.

  In the present modification, the lower surface 10 b of the damper rubber 10 is provided as an inclined surface portion 10 c that is inclined downward toward the rear of the vehicle with the hood 3 closed with respect to the seat surface 63. That is, in the closed state of the hood 3, as shown in FIG. 6A, the normal line of the inclined surface portion 10c (the lower surface 10b of the damper rubber 10) and the normal line of the seat surface 63 do not become parallel, and the inclined surface portion 10c. Is provided obliquely with respect to the seating surface 63. As a result, a wedge-shaped gap 7 similar to that described above is formed between the inclined surface portion 10 c and the seat surface 63.

  The inclination angle and the inclination direction of the inclined surface portion 10c with respect to the seat surface 63 are set in consideration of the instantaneous deflection of the hood 3 that may occur when the hood 3 is closed, as in the above-described embodiment. Specifically, as illustrated in FIG. 6B, the inclination angle with respect to the seating surface 63 is set so that the surfaces (the lower surface 10 b and the seating surface 63) that face each other when the hood 3 is closed are parallel to each other. Further, the direction in which the inclined surface portion 10c is inclined (whether it is downwardly inclined toward the front of the vehicle or downwardly inclined toward the rear of the vehicle) is also set in consideration of the instantaneous deflection that occurs when the hood 3 is closed. .

  Therefore, also in the vehicle body front portion structure of the present modification, the rigidity of the seat surface 63 can be increased by the bead portion 64 and the load concentration range can be reduced similarly to the above-described embodiment, and the same as described above. The effect of can be obtained. Further, when the hood 3 is strongly closed (when the load of the hood 3 acts on the seat surface 63 greatly), the lower surface 10b of the damper rubber 10 and the seat surface 63 come into contact with each other on a wide surface. Thereby, the load at the time of closing of the hood 3 can be disperse | distributed to the whole surface, and the effect similar to the above-mentioned embodiment can be acquired.

[3-4. Others]
The size, shape, number, and arrangement of the damper rubber 10 are not particularly limited. For example, a rubber member having a prism shape or a disk shape may be used, or three or more may be arranged in the vehicle width direction. Further, the damper rubber 10 may be fixed perpendicularly to the front upper surface 6 of the opening 2 of the vehicle body.
Further, the shape of the seating surfaces 33 and 63 is not particularly limited, and is protruded or recessed from the front lower surface 3b of the hood 3 or the front upper surface 6 of the opening 2 of the vehicle body (in the thickness direction) as in the above-described embodiment. It may not be formed with a step).

  Further, the length, position, and number of the bead portions 34 and 64 formed on the seating surfaces 33 and 63 are not limited to those described above. For example, two bead portions 34, 64 that extend linearly in the vehicle front-rear direction and are recessed may be formed side by side in the vehicle width direction of the seating surfaces 33, 63, or the length in the vehicle front-rear direction may be increased. The upper surface 10a or the lower surface 10b of the damper rubber 10 may be formed to be equal to or slightly shorter than the vehicle longitudinal direction length. In addition, the size of the seat surfaces 33 and 63 should just be formed larger than the upper surface 10a or the lower surface 10b of the damper rubber 10. Further, the number of the seating surfaces 33 and 63 is the same as the number of the damper rubbers 10, and the positions of the seating surfaces 33 and 63 are set corresponding to the arrangement of the damper rubbers 10.

In addition, any one of the upper surface 10a or the lower surface 10b of the damper rubber 10 facing the seat surface 33 and the seat surfaces 33, 63 is inclined forward or rearward of the vehicle with the hood 3 closed with respect to either of the other. The inclined surface portions 10c and 33c may not be provided. That is, the damper rubber 10 and the seating surface 33 may be provided so that the opposing surfaces are parallel to each other when the hood 3 is closed.
