Description

Vehicle exterior parts structure

The present invention relates to an exterior component structure of a vehicle in which resin exterior components are respectively provided on side sills and wheel arches of a vehicle body.

As an exterior part of a vehicle, a decorative side sill garnish provided along a side sill of a vehicle body is known. The side sill garnish is a member made of resin and has a coefficient of thermal expansion larger than that of the steel material that constitutes the vehicle body. That is, the side sill garnish expands and contracts more than the side sill.
For this reason, it is necessary to attach the side sill garnish to the side sill in consideration of the expansion and contraction of the side sill garnish.

Specifically, it is known that the rear end of the side sill garnish is fixed to the side sill with a screw member and the front end of the side sill garnish is supported movably in the vehicle longitudinal direction by the side sill (e.g., Patent Document 1) reference.).
According to the side sill garnish of Patent Document 1, it is possible to cope with the expansion and contraction due to the temperature change of the side sill garnish by moving the front end in the longitudinal direction of the vehicle body. As a result, expansion and contraction of the side sill garnish due to temperature change can be absorbed by moving the front end of the side sill garnish in the longitudinal direction of the vehicle body.

Also, as an exterior part of a vehicle, a decorative wheel arch protector provided on a wheel arch of a vehicle body is known. Specifically, a wheel arch is formed in an arc shape on the outer peripheral side of a wheel, and a resin wheel arch protector is attached along the wheel arch (see, for example, Patent Document 2).
According to the wheel arch protector of Patent Document 2, the locking hole is formed in the bumper of the vehicle, and the locking claw of the wheel arch protector is engaged with the locking hole. By engaging the locking pawls with the locking holes of the bumper, alignment of the wheel arch protector with respect to the wheel arch is facilitated.

Here, it is conceivable to provide the vehicle with both the side sill garnish and the wheel arch protector as exterior parts of the vehicle. In this case, a wheel arch protector on the front wheel side is continuously provided in front of the side sill garnish. In addition, a wheel arch protector for the rear wheel is continuously provided behind the side sill garnish.
For this reason, it is conceivable that expansion and contraction in the vehicle longitudinal direction due to temperature change of the side sill garnish is hindered by the wheel arch protector for the front wheel and the rear wheel, and it becomes difficult to secure the appearance of the vehicle favorably.

JP 2000-16342 A JP 2012-46087 A

An object of the present invention is to provide an exterior part structure of a vehicle that includes both members of a side sill garnish made of resin and a wheel arch protector made of resin and that can cope with expansion and contraction due to temperature change of both members.

According to the first aspect of the present invention, the resin-made side sill garnish attached to the side sill of the vehicle body from the vehicle outside and extending in the vehicle longitudinal direction, and the resin wheel attached to the wheel arch on one end side of the side sill garnish from the vehicle outside And an arch protector, wherein the side sill garnish is formed at the other end of the side sill garnish and fixed to the vehicle body, and the wheel from one end of the side sill garnish The wheel arch protector includes a step extending in the longitudinal direction of the vehicle body toward the arch protector and formed in a step-like shape so as to be recessed with respect to the surface of the side sill garnish. An extension extending towards the step so as to be superimposed; Extension and is provided in the stepped portion, the stepped portion, to provide exterior part structure of a vehicle including a support portion for movably supporting the extension portion toward the vehicle body front-rear direction.

In the invention according to claim 2, preferably, the exterior part structure of the vehicle is further attached to a wheel arch on the other end side of the side sill garnish from the vehicle outer side, and is disposed above the other end A resin wheel arch protector having a lower portion is provided, and the side sill garnish includes a protrusion extending upward along the lower portion of the protector, and the lower portion of the protector is provided with an insertion opening into which the protrusion is inserted. And a positioning rib which protrudes from the insertion port and positions the protrusion in the vehicle width direction.

In the invention according to claim 3, preferably, the lower portion of the protector includes a protector front wall disposed on the vehicle front side and a protector rear wall disposed on the vehicle rear side of the protector front wall; The garnish is expanded toward the lower part of the protector so as to be superimposed on the lower part of the protector from the vehicle inner side, and an upper part is formed in a step shape so as to be recessed with respect to the surface of the side sill garnish; And a rear engaging portion provided on the upper end portion and engageable to the back surface of the protector rear wall.

In the invention according to claim 4, preferably, the exterior part structure of the vehicle is further attached to the door of the vehicle from the outside of the vehicle and made of resin adjacent to the side sill garnish and the wheel arch protector on the other end side. Door wheel arch garnish, and the wheel arch on the other end side has a mounting flange projecting outward from the lower part of the wheel arch on the other end side in the vehicle width direction, and the mounting flange is provided with the side sill garnish The fixing portion is fixed, and surfaces of the side sill garnish, the wheel arch protector on the other end side, and the door wheel arch garnish are disposed flush.

In the invention according to claim 5, preferably, the door wheel arch garnish is formed between a first bonding portion and a second bonding portion bonded along the door, and between the first bonding portion and the second bonding portion. And a curved portion formed in a curved shape.

Here, the door wheel arch garnish is a member formed of a resin material. On the other hand, the door is a member usually made of steel. Thus, the door wheel arch garnish has a coefficient of thermal expansion (coefficient of linear expansion) greater than that of the door.
A door wheel arch garnish is adhesively bonded to the door. Therefore, it is conceivable that the door wheel arch garnish peels off from the door as the door wheel arch garnish expands and contracts due to temperature change.
Therefore, in claim 5, the curved portion is formed in a curved shape between the first bonding portion and the second bonding portion, and the expansion and contraction of the door wheel arch garnish is absorbed by the deformation of the curved portion.

In the invention according to claim 6, preferably, the side sill garnish includes an upper flange projecting upward from the upper edge of the side sill garnish along the side sill.

In the invention according to claim 1, the step portion is extended from the one end portion of the side sill garnish, and the extension portion of the wheel arch protector is superimposed on the step portion from the outside of the vehicle. Thus, the joint between one end of the side sill garnish and the extension of the wheel arch protector is covered by the step from the inside of the vehicle. As a result, since the joint between the one end and the extension can be continued at the step, the appearance of the joint (that is, the vehicle) can be favorably maintained.

In addition, the fixing portion at the other end of the side sill garnish is fixed to the vehicle body, and the step portion and the extension portion are supported movably in the vehicle longitudinal direction by the support portion. Thereby, when both members of the resin-made side sill garnish and the resin-made wheel arch protector expand and contract due to temperature change, the expansion and contraction of both members can be coped with by moving the step portion and the extension portion.
In other words, expansion and contraction due to temperature change of both members can be absorbed by moving the step portion or the extension portion. As a result, the installation of the wheel arch protector on the side sill garnish can be secured.

On the other hand, the fixing portion at the other end of the side sill garnish was fixed to the vehicle body. As a result, when the side sill garnish expands and contracts due to temperature change, the other end of the side sill garnish can be prevented from protruding in the longitudinal direction of the vehicle body or being recessed, and the appearance of the vehicle can be favorably maintained.

In the invention which concerns on Claim 2, the wheel arch protector of the other end part was equipped with the protector lower part. Also, the protrusion was extended upward from the side sill garnish. Furthermore, the protrusion was inserted into the insertion port at the bottom of the protector. Therefore, the insertion port can be moved in the vertical direction with respect to the protrusion.

Thereby, when the resin-made wheel arch protectors expand-contract by temperature change, it can respond to expansion-contraction of a wheel arch protector by moving a protector lower part.
In other words, expansion and contraction due to temperature change of the wheel arch protector can be absorbed by moving the lower part of the protector. As a result, the installation of the wheel arch protector on the side sill garnish can be secured.

Further, the positioning rib is extended from the insertion port, and the positioning rib positions the projection in the vehicle width direction. Therefore, the surface of the wheel arch protector (specifically, the lower part of the protector) can be held flush with the surface of the side sill garnish. As a result, the appearance of the side sill garnish and the seam at the lower part of the protector (i.e., the vehicle) can be favorably maintained.

In the invention which concerns on Claim 3, the upper stage part was bulged from the side sill garnish, and the upper stage part was overlap | superposed from the vehicle inner side on the protector lower part of the wheel arch protector. Therefore, the joint between the side sill garnish and the lower part of the protector is covered from the inside of the vehicle at the upper portion. Thereby, the seam between the side sill garnish and the lower part of the protector can be made continuous at the upper portion, and the appearance of the seam can be favorably maintained.

Further, a front engagement portion and a rear engagement portion are provided in the upper stage, and each engagement portion is engaged with the back surface of the protector front wall and the protector rear wall. Thereby, the wheel arch protector (specifically, the lower part of the protector) can be accurately positioned in the vehicle longitudinal direction with respect to the side sill garnish, and the appearance of the joint between the side sill garnish and the lower part of the protector can be further secured.

In the invention according to claim 4, the respective surfaces of the side sill garnish, the wheel arch protector on the other end side and the door wheel arch garnish are arranged flush. Therefore, it is possible to prevent the step between the side sill garnish, the wheel arch protector on the other end side, and the boundary of the door wheel arch garnish. Thereby, the appearance of the vehicle can be favorably maintained.

In the invention according to claim 5, the first bonding portion and the second bonding portion of the door wheel arch garnish are bonded along the door, and the curved portion is formed in a curved shape between the first bonding portion and the second bonding portion. By forming the curved portion in a curved shape, it is possible to suitably deform the curved portion by a load acting on the curved portion from the first bonding portion or the second bonding portion.
Therefore, when the door wheel arch garnish expands and contracts due to temperature change, the expansion difference with respect to the door can be absorbed by deforming the curved portion. Thereby, it is possible to hold the first bonding portion and the second bonding portion in a state of being bonded to the door, and it is possible to suppress peeling of each bonding portion from the door.

In the invention according to claim 6, the upper flange is projected upward along the side sill from the upper edge of the side sill garnish. By bringing the upper flange into contact with the side sill, a large contact area of the side sill garnish (specifically, the upper flange) in contact with the side sill can be secured.
Thus, the sealability between the side sill and the upper flange can be enhanced. As a result, the number of parts can be reduced without the need for arranging the conventionally required sealing material between the side sill and the upper flange.

It has a second locking portion 103 formed on the central upper surface and a stopper portion 104 formed at an interval on the second locking portion 103.

As shown in FIG. 11, the front clip 96 is a member made of resin, and the first locking portion 102 and the second locking portion 103 are formed so as to be elastically deformable. The first locking portion 102 is formed in an inclined manner so that the upper surface 102 a slopes upward from the tip portion 101 a side of the support bar 101 toward the base portion 101 b.
Furthermore, the first locking portion 102 can be inserted into the guide hole 106 of the front clip engaging portion 97, and can be locked to the locking hole 107 of the side sill 22 (specifically, the outer panel 31). Ru.

Further, like the first locking portion 102, the second locking portion 103 is formed in an inclined shape so that the upper surface 103a has an upward slope from the tip portion 101a side of the support bar 101 toward the base portion 101b. . Furthermore, the second locking portion 103 is formed to be lockable in the guide hole 106 of the front clip engaging portion 97.

The front clip engaging portion 97 has a bent portion 111 formed on the front side wall 67 a of the front portion 67 and a guide portion 112 extended from the inner edge of the bent portion 111 toward the front of the vehicle body. The bent portion 111 projects from the leading edge 67 b of the front side wall 67 a toward the vehicle interior 27. Further, the guide portion 112 is formed at the leading edge 67 b of the front stage portion 67 via the bent portion 111.
Accordingly, the guide portion 112 is disposed at a distance from the side wall 91c of the extended outer peripheral portion 91 toward the vehicle interior 27 (see also FIG. 7).

In the guide portion 112, a guide hole 106 is formed to have a hole length L2 so as to extend in the longitudinal direction of the vehicle body. The hole length L2 is larger than the width W1 of the support bar 101. The guide hole 106 is formed so as to be insertable from the outer side 26 by elastically deforming the first locking portion 102 and the second locking portion 103.

Referring back to FIGS. 7 and 10, the second locking portion 103 is inserted into the guide hole 106, whereby the stopper portion 104 contacts the surface 112a of the guide portion 112, and the second locking portion 103 is in the guide portion 112. Contacts the back surface 112b of the Thereby, the front clip 96 is locked to the front clip engaging portion 97.
In addition, the first locking portion 102 is locked to the outer panel 31 by penetrating the locking hole 107 of the side sill 22 (specifically, the outer panel 31).

In this manner, the front clip 96 is locked to the front clip engaging portion 97, and the first locking portion 102 is locked to the outer panel 31 of the side sill 22, so that the front portion 67 and the extension 85 can be moved forward. It is supported by the support portion 53.
A front portion 67 is formed on the front end 51 b of the side sill garnish 51, and an extension 85 is formed on the front wheel arch protector 52. Thus, the side sill garnish 51 and the front wheel arch protector 52 are supported by the front support portion 53.

Here, the hole length L 2 of the guide hole 106 is formed larger than the width W 1 of the support bar 101. Further, the front seam 94 of the front end portion 51b of the side sill garnish 51 and the extended outer peripheral portion 91 is formed at an interval L1.
Therefore, in a state where the front clip 96 is locked to the front clip engaging portion 97, the front clip 96 and the front clip engaging portion 97 are directed toward the vehicle front (in the direction of arrow Fr) or in the rear (in the direction of arrow Rr). Movably supported.

On the other hand, the fixing portion 65 of the rear end portion 51a of the side sill garnish 51 is fixed to the rear mounting flange 44 by a plurality of clips 72 (see FIG. 4). Therefore, when the resin-made side sill garnish 51 expands and contracts in the vehicle longitudinal direction due to temperature change, the front end 51b of the side sill garnish 51 moves in the vehicle longitudinal direction (arrow Fr direction and arrow Rr direction).

Thereby, when the resin-made side sill garnish 51 and the resin-made extension part 85 expand and contract in the vehicle longitudinal direction due to temperature change, the front clip 96 and the front clip engaging portion 97 can be moved in the vehicle longitudinal direction it can.
As described above, by providing the front support portion 53 on the outer peripheral portion 91 of the extension portion 85 and the front portion 67 of the side sill garnish 51, the vehicle front and rear direction of the side sill garnish 51 and the extension portion 85 (arrow Fr direction and arrow Rr direction) Can correspond to the

In other words, expansion and contraction in the vehicle longitudinal direction due to temperature changes of the side sill garnish 51 and the extension portion 85 can be absorbed by moving the front clip 96 and the front clip engaging portion 97 in the vehicle longitudinal direction. Therefore, it is possible to suppress that the load due to the temperature change acts on the side sill garnish 51 and the extension portion 85.
As a result, it is possible to secure the erection performance of the front wheel arch protector 52 with respect to the side sill garnish 51.

As shown in FIGS. 2 and 8, a rear wheel arch protector 54 is attached to the rear wheel arch 24. The rear wheel arch protector 54 is a resin member, and has a rear side wall 115 formed in an arc shape along the rear wheel arch 24 and a rear protector lower portion 116 formed on the front lower end 115 a of the rear side wall 115 Have.

The surface 121 a of the protector outer wall 121 is disposed flush with the surface 51 d of the protrusion 75. The surface 51 d of the raised portion 75 is formed by the surfaces of the raised side wall 75 a, the raised front wall 75 b, and the raised rear wall 65 a.

The protector outer wall 121 includes a protector front wall 124 disposed on the front side of the vehicle body, a protector rear wall 125 disposed on the vehicle rear side of the protector front wall 124, and an outer edge of the protector front wall 124 and the protector rear wall 125. And a protector side wall 126 connecting the outer edge.
The protector outer wall portion 121 is formed to have a substantially U-shaped cross section by the protector front wall 124, the protector rear wall 125 and the protector side wall 126.

The protector outer wall portion 121 formed in a substantially U-shaped cross section is extended toward the protruding portion 75 so as to be superimposed on the upper stage portion 76 from the vehicle exterior 26 side.
As described above, the protector outer wall 121 is superimposed on the upper portion 76, whereby the surface 121a of the protector outer wall 121 and the surface 51d of the raised portion 75 are flush with each other (see also FIG. 4). Thereby, the protruding part 75 and the protector outer wall part 121 are connected in the state which maintained external appearance favorable.

As shown in FIG. 4 and FIG. 14, by superposing the protector outer wall portion 121 on the upper stage portion 76, the upper joint 128 of the raised portion 75 and the protector outer wall portion 121 is formed with a space L3 (see FIG. 14). Be done.
The spacing L3 of the upper joint 128 ensures good construction of the ridge 75 and the protector outer wall 121 when the side sill garnish 51 (in particular, the ridge 75) and the rear wheel arch protector 54 stretch due to a temperature change. It is a so-called cut-off width that is determined as follows.
The upper joint 128 is covered from the vehicle interior 27 side by the upper stage portion 76 in a state where the protector outer wall portion 121 is superimposed on the upper stage portion 76. Thereby, the upper joint 128 can be continued at the upper portion 76, and the appearance of the upper joint 128 (that is, the vehicle 10) can be favorably maintained.

Referring back to FIGS. 12 and 13, the front locking portion 131 is formed in a concave shape on the back surface 124 a of the lower portion of the protector front wall 124. The front locking claw 78 a of the front engagement portion 78 is locked to the front locking portion 131. The front locking portion 131 is formed to allow movement of the front locking claw 78a in the vertical direction in a state where the front locking claw 78a of the front engagement portion 78 is locked.

In addition, a rear locking portion 132 is formed in a concave shape on the lower surface 125 a of the lower portion of the protector rear wall 125. The rear locking claw 79 a of the rear engagement portion 79 is locked to the rear locking portion 132. The rear locking portion 132, like the front locking portion 131, allows movement of the rear locking claw 79a in the vertical direction in a state where the rear locking claw 79a of the rear engagement portion 79 is locked. It is formed.

A plate 122 is provided substantially horizontally above the front engagement portion 78 and the rear engagement portion 79. The plate 122 has a substantially rectangular outer shape, and an insertion port 134 into which the projection 77 of the upper support 66 is inserted from below, and a positioning rib 135 formed on the insertion port 134 for positioning the projection 77 Equipped with

As shown in FIG. 15, the insertion port 134 is formed in a substantially rectangular shape, and has an outer edge 134a and an inner edge 134b. The positioning rib 135 protrudes from the inner edge 134 b of the insertion port 134 toward the outer side 26 of the vehicle. The positioning rib 135 is an overhanging piece for positioning the projecting portion 77 in the vehicle width direction.
The positioning rib 135 has a front overhanging piece 135b projecting from the front end portion 135a toward the vehicle exterior 26 and a rear overhanging piece 135d projecting from the rear end portion 135c toward the vehicle exterior 26.

As shown in FIG. 14, in a state where the protector outer wall portion 121 is superimposed on the upper end portion 76 from the vehicle exterior 26 side, the projecting portion 77 is inserted into the insertion port 134 of the plate 122 from below. Therefore, the protrusion 77 and the insertion port 134 can be relatively moved in the upward direction (arrow Up direction) or in the lower direction (arrow Dw direction). Specifically, the insertion port 134 can be moved in the vertical direction with respect to the protrusion 77.
Further, the upper seam 128 of the raised portion 75 of the side sill garnish 51 and the protector outer wall portion 121 is formed with a space L3.

Therefore, when the rear wheel arch protector 54 made of resin expands and contracts in the vertical direction due to temperature change, the plate 122 can be moved in the vertical direction (arrow Up direction or arrow Dw direction) along the protrusion 77. Thereby, the rear protector lower portion 116 of the rear wheel arch protector 54 can be moved in the vertical direction.
Therefore, it is possible to cope with expansion and contraction in the vertical direction (the arrow Up direction and the arrow Dw direction) due to the temperature change of the rear wheel arch protector 54.

In other words, the expansion and contraction in the vertical direction due to the temperature change of the rear wheel arch protector 54 can be absorbed by moving the plate 122 (specifically, the lower rear protector portion 116) in the vertical direction. Therefore, it is possible to suppress the load due to the temperature change acting on the rear wheel arch protector 54 and the raised portion 75 of the side sill garnish 51.
As a result, it is possible to ensure the erecting property of the rear wheel arch protector 54 (specifically, the lower rear protector portion 116) with respect to the raised portion 75 of the side sill garnish 51.

As shown in FIGS. 9 and 15, the protrusion 77 is inserted into the insertion port 134 from below. In this state, the projecting side wall 77 a of the projecting portion 77 contacts the outer edge 134 a of the insertion port 134. Further, the front rib 77 b and the rear rib 77 c of the projection 77 come in contact with the positioning rib 135 of the insertion port 134.
Accordingly, the protrusion 77 is positioned by the positioning rib 135 in the vehicle width direction. As a result, the rear protector lower portion 116 is accurately positioned relative to the raised portion 75 in the vehicle width direction.

Further, the positioning rib 135 has a front overhanging piece 135b and a rear overhanging piece 135d. Therefore, in the state where the projection 77 is inserted into the insertion port 134, the movement of the front rib 77b of the projection 77 to the front of the vehicle body is restricted by the front overhanging piece 135b. Further, the movement of the rear rib 77c of the projection 77 toward the rear of the vehicle body is restricted by the rear overhanging piece 135d.
Further, the front locking claw 78a of the front engagement portion 78 is locked to the front locking portion 131 of the back surface 124a of the protector front wall 124. Further, the rear locking claw 79a of the rear engaging portion 79 is locked to the rear locking portion 132 (see FIG. 12) of the rear surface 125a of the protector rear wall 125.
As a result, the rear protector lower portion 116 is accurately positioned relative to the raised portion 75 in the vehicle body longitudinal direction.

As shown in FIG. 4 and FIG. 14, the rear protector lower portion 116 is accurately positioned with respect to the raised portion 75 in the vehicle width direction and the vehicle longitudinal direction. Therefore, the surface 121 a of the rear protector lower portion 116 is held flush with the surface 51 d of the raised portion 75.
Thereby, the appearance of the upper seam 128 of the raised portion 75 and the rear lower protector portion 116 can be favorably secured.

As shown in FIG. 2, a resin-made door wheel arch garnish 55 is attached to the rear lower portion 15 a of the rear side door 15 from the outside 26 side. The rear lower portion 15 a of the rear side door 15 is a curved portion extending from the rear end portion 51 a of the side sill garnish 51 along the front portion 54 a of the rear wheel arch protector 54.

A door wheel arch garnish 55 is attached to the rear lower portion 15a of the rear side door 15 from the outside 26 side. The door wheel arch garnish 55 is disposed adjacent to the rear end portion 51 a of the side sill garnish 51 and the front portion 54 a of the rear wheel arch protector 54 (see also FIG. 1).

As shown to FIG. 4, FIG. 6, the door wheel arch garnish 55 is a resin-made member formed in side view substantially curved shape (also refer FIG. 1). The door wheel arch garnish 55 includes an outer door garnish 141 facing the outer side 26 of the vehicle and an inner door garnish 142 provided inside the outer door garnish 141.

The outer door garnish 141 is directed from the outer edge of the rear wall 146 to the outer panel 144 of the rear side door 15 from the outer edge of the rear wall 146 facing the raised front wall 75 b of the raised portion 75 and the protector front wall 124 of the rear wheel arch protector 54. And an inclined front wall portion 147.

The outer door garnish 141 is formed to have a substantially V-shaped cross section by the rear wall 146 and the front inclined wall 147. Furthermore, the outer side portion 55 b of the outer door garnish 141 is formed at the intersection of the rear wall portion 146 and the front inclined wall portion 147.
The outer side portion 55 b is an outer side portion of the door wheel arch garnish 55, and is a portion that forms a part of the surface 55 a of the door wheel arch garnish 55.

The inner door garnish 142 is interposed between the inner edge 146 a of the rear wall 146 and the inner edge 147 a of the front inclined wall 147, and is disposed along the outer panel 144 of the rear side door 15. The inner door garnish 142 includes a first bonding portion 151 and a second bonding portion 152 extending in the vertical direction along the rear side door 15, and a curved portion 153 formed between the first bonding portion 151 and the second bonding portion 152. And (see also FIG. 9).

The first bonding portion 151 is provided on the front side of the vehicle body in comparison with the second bonding portion 152. The first bonding portion 151 and the inner edge 147 a of the front inclined wall portion 147 are bonded along the outer panel 144 of the rear side door 15 with the adhesive 155.
Also, the second bonding portion 152 and the inner edge 146 a of the rear wall 146 are bonded along the outer panel 144 of the rear side door 15 with the adhesive 156.
As a result, the door wheel arch garnish 55 is attached to the rear lower portion 15 a of the rear side door 15 from the outside 26 side.

Here, the curved portion 153 is formed between the first bonding portion 151 and the second bonding portion 152. The curved portion 153 is formed in a curved shape so as to be recessed toward the outer door garnish 141, and extends in the vertical direction along the first bonding portion 151 and the second bonding portion 152.
In other words, the curved portion 153 is formed in the shape of a vertical groove extending in the vertical direction along the first bonding portion 151 and the second bonding portion 152.

The reason why the curved portion 153 is formed in the first bonding portion 151 and the second bonding portion 152 is as follows. That is, the door wheel arch garnish 55 made of resin has a coefficient of thermal expansion larger than that of the rear side door 15. For this reason, it is conceivable that the first adhesive portion 151 and the second adhesive portion 152 peel off from the outer panel 144 when the door wheel arch garnish 55 expands and contracts (especially, expands and contracts in the vehicle longitudinal direction) due to temperature change.

Therefore, the curved portion 153 was formed between the first bonding portion 151 and the second bonding portion 152. Therefore, when the door wheel arch garnish 55 expands and contracts due to a temperature change, it is possible to suitably deform the bending portion 153 by the load acting on the bending portion 153 from the first bonding portion 151 and the second bonding portion 152.

Thus, when the door wheel arch garnish 55 expands and contracts in the longitudinal direction of the vehicle body due to a temperature change, the expansion difference with respect to the rear side door 15 can be absorbed by deforming the curved portion 153.
Therefore, the first adhesive part 151 and the second adhesive part 152 can be held in a state of being adhered to the rear side door 15, and the peeling of the first adhesive part 151 and the second adhesive part 152 from the rear side door 15 is suppressed. Can.

Further, a door wheel arch garnish 55 is attached to the rear lower portion 15 a of the rear side door 15. In this state, the door wheel arch garnish 55 is disposed adjacent to the raised portion 75 of the side sill garnish 51 and the rear wheel arch protector 54 (in particular, the rear lower portion 116).
Here, the outer portion 55b of the door wheel arch garnish 55 and the raised side wall 75a of the raised portion 75 are flush with each other on a straight line 160 extending in the longitudinal direction of the vehicle body.

Further, as shown in FIG. 15, the outer side portion 55b of the outer door garnish 141 and the protector side wall 126 of the rear protector lower portion 116 are disposed flush with each other on a straight line 160 extending in the vehicle longitudinal direction.
Also, the protector side wall 126 is formed flush with the rear side wall 115 (see FIG. 4) of the rear wheel arch protector 54. Therefore, the outer side portion 55 b of the outer door garnish 141 and the rear side wall 115 of the rear wheel arch protector 54 are disposed flush with each other on a straight line 160 extending in the vehicle longitudinal direction.

Furthermore, as shown in FIG. 14, the surface 51 d of the raised portion 75 and the surface 121 a of the rear protector lower portion 116 are disposed flush. The surface 51 d of the raised portion 75 is the surface 51 d of the side sill garnish 51. Further, the surface 121 a of the rear protector lower portion 116 is a part of the surface of the rear wheel arch protector 54.
Therefore, the surface 51 d of the side sill garnish 51 and the surface of the rear wheel arch protector 54 (including the surface 121 a of the rear protector lower portion 116) are arranged flush.
In addition, it is a part that forms a part of the outer side 55 b of the door wheel arch garnish 55 and the surface 55 a of the door wheel arch garnish 55.

Thereby, as shown in FIG. 4, the surface 51 d of the side sill garnish 51, the surface of the rear wheel arch protector 54, and the surface (specifically, the outer side portion) 55b of the door wheel arch garnish 55 are arranged flush. .
Therefore, it is possible to prevent steps from being generated at the boundaries of the side sill garnish 51, the rear wheel arch protector 54 and the door wheel arch garnish 55. Therefore, the side sill garnish 51, the rear wheel arch protector 54 and the door wheel arch garnish 55 can be formed flat, and the appearance of the vehicle 10 can be favorably maintained.

Next, an example in which the front support portion 53 absorbs elongation due to temperature change of the resin-made side sill garnish 51 and the resin-made extension portion 85 will be described based on FIG. 4 and FIG.
As shown in FIG. 4, a fixing portion 65 is formed at the rear end portion 51 a of the side sill garnish 51, and the fixing portion 65 is fixed to the rear mounting flange 44 of the vehicle body 11.
In this state, the side sill garnish 51 made of resin extends due to the temperature change of the high temperature state.

As shown in FIG. 16A, the resin-made side sill garnish 51 is extended due to a temperature change, so that the front end portion 51 b of the side sill garnish 51 moves in the forward direction of the vehicle (in the direction of the arrow Fr).
At the same time, the extension 85 of the front wheel arch protector 52 made of resin extends rearward of the vehicle (in the direction of the arrow Rr) due to the temperature change in the high temperature state.

In this state, the front clip engaging portion 97 moves in the front of the vehicle body (in the direction of the arrow Fr), and the front clip 96 of the front support portion 53 moves in the direction of the arrow Rr. Therefore, the load due to the extension of the side sill garnish 51 or the extension 85 does not act on the front part 67 or the extension 85 of the side sill garnish 51.
Thereby, the extension of the side sill garnish 51 and the extension portion 85 can be absorbed by the front support portion 53.

As shown in FIG. 16B, the front supporting portion 53 absorbs the extension of the side sill garnish 51 and the extension portion 85, whereby the surface 51 d of the side sill garnish 51 and the surface 91 b of the extension portion 85 are flat and even. You can keep
This makes it possible to secure the building performance of the front wheel arch protector 52 with respect to the side sill garnish 51, and to ensure the good appearance of the vehicle 10 (particularly, the front joint 94).

Next, an example in which the extension due to temperature change of the rear wheel arch protector 54 made of resin is absorbed by the upper support portion 66 of the side sill garnish 51 will be described based on FIG.
As shown in FIG. 17A, the rear wheel arch protector 54 made of resin extends due to temperature change in a high temperature state. As a result, the rear protector lower portion 116 of the rear wheel arch protector 54 moves downward (in the direction of the arrow Dw).

In this state, the plate 122 of the rear protector lower portion 116 moves downward (in the direction of the arrow Dw) along the projecting portion 77 of the upper support portion 66 of the side sill garnish 51. Therefore, no load due to the extension of the rear wheel arch protector 54 acts on the rear protector lower portion 116 or the raised portion 75 of the side sill garnish 51.
Thereby, the extension of the rear wheel arch protector 54 can be absorbed by the upper support portion 66.

As shown in FIG. 17B, by absorbing the extension of the rear wheel arch protector 54 by the upper support portion 66, the surface 121a of the rear protector lower portion 116 and the surface 51d of the raised portion 75 are flat and flush. You can keep it.
This makes it possible to secure the erection performance of the rear wheel arch protector 54 with respect to the raised portion 75 of the side sill garnish 51, and to ensure excellent appearance of the vehicle 10 (particularly, the upper joint 128).

The exterior component structure of the vehicle according to the present invention is not limited to the above-described embodiment, and appropriate changes, improvements, and the like can be made.
For example, in the above embodiment, the other end of the side sill garnish 51 is the rear end 51a, the one end is the front end 51b, the fixing portion 65 is formed on the rear end 51a, and the front end 67 is formed on the front end 51b. Although an example has been described, it is not limited thereto.
For example, the fixing portion is formed at the front end 51b of the side sill garnish 51, the fixing portion is fixed to the vehicle body 11, and the rear end 51a of the side sill garnish 51 is formed with a rear part (a member playing the same role as the front part 67). It is also possible.

In the above embodiment, the front engagement claw 78a is formed at the upper end of the front engagement portion 78 and the rear engagement claw 79a is formed at the upper end of the rear engagement portion 79. However, the invention is not limited thereto. It is not a thing. For example, it is also possible to form another engagement portion such as a projection on the upper end of the front engagement portion 78 or the rear engagement portion 79.
