SUMMERY OF THE UTILITY MODEL

[ problems to be solved by the novel ]

When the spacer member is deformed in a state of being installed on the upper surface of the side sill (side wall), Noise and Vibration (NV), which is the performance of Noise and Vibration, are deteriorated due to the generation of a gap or the leakage of the filler.

An object of the present invention is to provide a vehicle body side portion structure that can suppress the deformation of a spacer member and suppress the deterioration of NV performance.

[ means for solving problems ]

In order to achieve the above object, the present invention provides a vehicle body side portion structure including: a center pillar (for example, a center pillar 3 described later) having a fan-shaped root; an inner panel (e.g., a center pillar inner panel (32) described later) constituting a part of the center pillar, the inner panel having a pair of filling ports formed in the vicinity of bent portions (e.g., bent portions 3b and 3c described later) in front of and behind the root portion (e.g., root portion 3a described later); and a spacer member (e.g., a spacer member 4 described later) disposed on an upper side of a side sill reinforcement plate (e.g., a side sill outer plate (21) described later), and having an opening (e.g., filling openings 41a and 41b described later) facing the filling openings (e.g., filling openings 32b and 32c described later) and an integrated body portion (e.g., a body portion 40 described later); a filling space (for example, a filling space 30 described later) extending at least in the front-rear direction is formed between the spacer member and a center pillar reinforcement plate (for example, a center pillar reinforcement plate 33 described later) constituting a part of the center pillar, and the spacer member includes a first rib (for example, a projecting piece 46 described later) extending below the opening.

Thus, since the opening portion of the spacer member includes the first rib extending downward, the portion of the spacer member near the filling port can be prevented from sinking in the vertical direction. Therefore, a gap can be prevented from being generated in this portion, and thus the sound insulating performance can be improved.

In this case, it is preferable that the spacer member has a plurality of tubular recessed portions (e.g., recessed portions 47 and 48 described later) formed by downwardly recessing a part of the main body portion, a lower end portion of one of the recessed portions (e.g., recessed portion 47 described later) has a fixing portion (e.g., a locking portion 47a described later) to a rocker (e.g., rocker 2 described later), a lower end portion of the other recessed portion has a second rib (e.g., a protruding piece 48a described later), and the first rib is disposed further toward the vehicle front-rear direction outer side than the second rib. Thus, the end portion of the spacer member, which cannot be completely supported by the fixing portion and the second rib, can be supported by the first rib, and thus, the end portion can be prevented from sagging.

In this case, it is preferable that the first rib and the second rib are formed in a plate shape and arranged such that an extension line of the first rib (for example, an extension line L1 described later) and an extension line of the second rib (for example, an extension line L2 described later) intersect in a plan view. Thus, even when any one of the first rib and the second rib slides, the spacer member can be prevented from sinking downward.

In this case, it is preferable that the first rib is formed so as to face in the vehicle front-rear direction, and the second rib is formed so as to face in the vehicle width direction. Thereby, even in such a case that one of the ribs is deformed or slid, sinking of the spacer member can be prevented by the other rib. Further, since the first rib has a width in the vehicle width direction, it is possible to effectively prevent sinking when a foaming agent as a filler is injected.

In this case, it is preferable that the lower end of the first rib is disposed at a position higher than the lower end of the second rib. Thus, since the vertical length of the first rib is formed shorter than that of the second rib, the portion of the spacer member near the filling opening can be suppressed from sinking downward without reducing the workability of providing the spacer member. Further, since the space is formed below the first rib, the foaming agent can be filled into the vehicle front-rear direction end portion of the filling space.

In this case, it is preferable that the first rib extends downward at a distance from the rocker reinforcement plate. This can prevent the portion of the spacer member near the filling port from sinking downward, without reducing the workability of providing the spacer member. Further, since the space is formed below the first rib, the foaming agent can be filled into the vehicle front-rear direction end portion of the filling space.

In this case, it is preferable that the area of the first rib and the area of the second rib are respectively reduced toward the vehicle vertical direction downward, and an angle (for example, an angle a0) formed by a vehicle width inner edge (for example, a vehicle width inner edge 461) of the first rib and a vehicle vertical direction (for example, a vehicle vertical direction V) is formed smaller than an angle (for example, an angle a1) formed by a vehicle width outer edge (for example, a vehicle width outer edge 462) and the vehicle vertical direction (for example, a vehicle vertical direction V).

This can suppress a decrease in the fluidity of the foaming agent filled in the filling space and also suppress a downward sinking of the portion of the spacer member near the filling port. In addition, by setting the angle formed by the vehicle width inner edge of the first rib to be small, the load generated by the foaming agent contacting the opening portion can be supported, and the sagging of the portion of the spacer member near the filling opening can be suppressed.

In this case, it is preferable that the opening of the spacer member is formed by a filler-mouth receiving portion (for example, filler-mouth receiving portions 43a and 43b described later) and a guide portion (for example, guide portions 45a and 45b described later) connecting the covering portions (for example, covering portions 42a and 42b described later), and the first rib extends downward from the filler-mouth receiving portion. Thus, the load of the foaming agent applied to the filling port receiving portion when the foaming agent is injected can be supported by the first ribs, and sagging of the spacer member in the vicinity of the filling port can be suppressed.

(novel Effect)

According to the present invention, it is possible to provide a vehicle body side portion structure that can suppress the deformation of the spacer member and suppress the decrease in NV performance.

A vehicle having a vehicle body side portion structure includes a center pillar 3 serving as a hollow vehicle body frame 10, and the hollow vehicle body frame 10 is capable of injecting a filler such as a foaming agent into a closed cross section. The vehicle body side portion structure a constitutes left and right vehicle body side portions 1a of a vehicle body 1, and includes a rocker 2, a center pillar 3, a filling space 30 for filling a filler into the center pillar 3 (a vehicle body frame 10), and a spacer member 4 for forming the filling space 30.

A door opening 1b opened and closed by a side door, not shown, is formed in front and rear of the center pillar 3 at a central portion in the front-rear direction of the vehicle body side portion 1 a. Since the vehicle body side portion 1a of the vehicle body 1 has a substantially bilaterally symmetric shape, the description will be given mainly on the left side, and the description on the right side will be omitted.

As shown in fig. 1, the rocker 2 is formed of a hollow frame member disposed at a lower portion of the vehicle body and extending in the front-rear direction, and includes a rocker outer panel 21 formed of a rocker reinforcement panel and a rocker inner panel 22. The rocker inner 22 is joined to the vehicle width inner side of the rocker outer 21 via the center pillar inner 32. Further, a spacer member 4 is placed on the upper surface of the rocker 2. A cross member, a floor panel, and the like, not shown, are connected to the vehicle width direction inner side of the rocker 2.

The center pillar 3 is constituted by a pillar-shaped hollow member constituting a part of the vehicle body side portion 1 a. The center pillar 3 extends upward from a central portion in the front-rear direction of the rocker 2 to a roof side rail (not shown). The center pillar 3 has a hollow portion having a closed cross section formed by joining a center pillar outer panel 31, a center pillar inner panel 32, and a center pillar reinforcement panel 33.

As shown in fig. 1, the lower portion of the center pillar 3 has: a root portion 3a formed in a fan shape having a width in the front-rear direction that is wider as it faces downward in a side view; and arc-shaped curved portions 3b,3c formed on the front and rear outer peripheral portions of the root portion 3 a. An opening portion 32a for installing a seatbelt retractor, not shown, in the center pillar 3 and a plurality of charging ports 32b,32c are formed in the vehicle interior side surface of the center pillar inner panel 32 of the center pillar 3.

The upper half portion of the center pillar 3 on the vehicle interior side is covered with an interior trim, that is, a pillar garnish, not shown. The opening portion 32a formed in the lower half portion of the center pillar 3 on the vehicle interior side and the seatbelt retractor (not shown) are covered with a side lining (not shown).

The filling space 30 is a space for filling the filler. The filling space 30 is formed between a center pillar inner panel 32 and a center pillar reinforcement panel 33 as inner panels, and extends in the front-rear direction as shown in fig. 1.

The filler filled in the filling space 30 is composed of a structural foaming agent. Specifically, the filler is, for example, a fast-curing foamed polyurethane foam which is liquid at room temperature, but is composed of a spray rubber (also referred to as a spray foam, a liquid rubber, or a liquid rubber) which becomes rubber-like when dried, is stored in a spray can or the like, and when discharged, is discharged in a foam-like state and is cured into a sponge-like state. The cured filler functions as a sound-insulating material, a vibration energy-absorbing material, and an impact energy-absorbing material.

The filler is filled in the filling space 30 and bonded to the same, thereby sealing the lower portion of the hollow portion 3d formed by the center pillar inner panel 32, the center pillar reinforcement panel 33, and the upper surface portion 21b of the rocker outer panel 21. The filler is not limited to the foamed polyurethane foam, and may be a synthetic foamed resin or a thermosetting foamed resin which is formed into a foamed or porous shape by heating. The filler may be an adhesive having elasticity such as polyurethane or rubber such as silicone, which has good adhesion to metal.

The center pillar outer 31 is a member forming the vehicle outer side surface of the center pillar 3. The center pillar outer 31, the center pillar inner 32, and the center pillar reinforcement 33 are formed by press-working a metal flat plate member such as high tensile steel, for example. The center pillar inner 32 is a member that forms a surface of the center pillar 3 in the vehicle compartment. As shown in fig. 1, the center pillar inner panel 32 is formed with an opening portion 32a, filling ports 32b,32c, and flange portions 32d,32 e.

The opening portion 32a constitutes a retractor installation opening for installing a seatbelt retractor not shown. The opening portion 32a includes a lower portion formed on the vehicle width direction inner side of the center pillar inner panel 32, and the lower portion has a substantially quadrangular hole having a W shape.

The filling ports 32b,32c are formed by two holes formed in the vicinity of the bent portions 3b,3c and in front of the lower end portion of the opening portion 32 a. The filling ports 32b and 32c are supply ports for filling the filling space 30 of the center pillar 3 with the filler. The filling port 32b is formed by a circular hole formed between the bent portion 3b on the rear side and the lower end portion of the opening portion 32a in the front-rear direction. The filling port 32c is formed by a circular hole formed between the bent portion 3c on the front side and the lower end portion of the opening portion 32a in the front-rear direction. The shape of the filling ports 32b and 32c is not limited to a circular hole, as long as it is formed in accordance with the shape of a filling nozzle, not shown. The flange portions 32d,32e are formed in plate shapes that constitute front-rear direction edge portions of the center pillar inner panel 32 extending in the up-down direction and are band-shaped.

The center pillar reinforcement 33 is a metal plate member for reinforcement provided between the center pillar outer panel 31 and the center pillar inner panel 32. The lower end of the center pillar reinforcement panel 33 is joined to the rocker outer panel 21 and the center pillar outer panel 31 of the rocker 2.

The spacer member 4 is a resin-made member provided to vertically space the lower portion of the center pillar 3 in the hollow portion 3d between the center pillar outer panel 31 and the center pillar inner panel 32. The spacer member 4 is provided so as to form a filling space 30 between the center pillar reinforcing plate 33 and the upper surface portion 21b of the rocker outer panel 21 (the upper surface 21b of the rocker 2) in the hollow portion 3d of the center pillar 3.

As shown in fig. 3 to 7, the spacer member 4 includes: the main body 40, the folded portion 40a, the swinging portion 40b, the filling opening portions 41a,41b, the covering portions 42a,42b, the filling port receiving portions 43a,43b, the inclined portions 43c,43d, the cutout portions 43e,43f, the guide portions 45a,45b, the step portion 45c, the recessed portion 47, the locking portion 47a, the recessed portion 48, the bending portion 49, and the regulating mechanism 49 a.

As shown in fig. 1, the main body portion 40 is formed of a flat plate-like portion extending in the front-rear direction along the upper surface (upper surface portion 21b) of the rocker 2. When the spacer member 4 is disposed in the hollow portion 3d, the body portion 40 is disposed below the lower opening edge of the opening portion 32 a. Thereby, the spacer member 4 suppresses the filler filled in the filling space 30 from leaking from the opening 32 a.

As shown in fig. 3 and the like, a folded portion 40a extending in the left-right direction is formed at the center portion of the upper surface of the main body portion 40. A vehicle width direction inside cutout groove 40c is formed at the right end of the folded portion 40 a. A vehicle width direction outer cutout groove 40d is formed in a left end portion of the folded portion 40 a. This allows the folded portion 40a to be easily folded. Recessed portions 47,48 are formed in the front and rear of the folded portion 40a of the main body portion 40. Thus, the main body portion 40 has a positional relationship surrounding the recessed portions 47, 48. Covering portions 42a,42b are formed at the front and rear end portions on the vehicle width direction inner side (right side) of the main body portion 40.

A curved portion 49 is formed on the upper surface of the vehicle width direction outer side (left side) of the main body portion 40 via the swing portion 40b, the rear cutout groove 40h, and the front cutout groove 40 i. On the lower surface of the body 40, the outer surfaces of the projecting piece 46 and the recessed portions 47,48, the locking portion 47a, the projecting piece 48a, the regulating means 49a, and the reinforcing projecting piece 40j project downward.

The covering portions 42a and 42b orient the filler injected into the filling space 30 from the filling ports 32b and 32c (see fig. 1) to flow toward the hard-to- fill portions 44a and 44b (see fig. 1) (in the direction of arrow g in fig. 4). The covering portions 42a,42b are formed of two front and rear members facing the filling ports 32b,32c, respectively. The rear covering portion 42a extends obliquely upward from the rear end of the body 40 toward the rear hard-to-fill portion 44a so as to cover the upper portion of the filling port 32 b. The front covering portion 42b extends obliquely upward from the front end of the body 40 toward the front hard-to-fill portion 44b so as to cover the upper portion of the filling port 32 c.

The filling port receiving portions 43a and 43b are plate-shaped portions that receive the filler injected from the filling ports 32b and 32c (see fig. 1) from below the filling ports 32b and 32 c. The filler neck receiving portions 43a,43b project from the lower end portions of the guide portions 45a,45b toward the filler necks 32b,32c (inward in the vehicle width direction). The filling port receiving portions 43a,43b are separated from the center pillar inner panel 32 of the vehicle body frame 10.

As shown in fig. 3 and 4, the filling port receiving portions 43a,43b form inclined portions 43c,43d, and the inclined portions 43c,43d extend in the vehicle body front-rear direction from the lower portions of the covering portions 42a,42b, and are inclined downward as they are farther from the lower portions of the covering portions 42a,42 b. The filling port receiving portions 43a,43b are formed to have a thinner plate thickness on the lower side (i.e., closer to the left and right end portions in fig. 4) away from the covering portions 42a,42 b.

As shown in fig. 6, cut-out portions 43e,43f are formed in the filling port receiving portions 43a,43b so that the widths thereof in the left-right direction are expanded as they approach the lower portions of the covering portions 42a,42 b. The notches 43e and 43f form flow paths for allowing the filler injected from the filling ports 32b and 32c on the front and rear sides to flow toward the center portion between the filling ports 32b and 32c (the center portion in fig. 4) for easy filling.

The cutout portions 43e,43f are formed in a crank (crank) shape in a bottom view. The filling port receiving portions 43a,43b are configured by forming notch portions 43e,43 f: a large gap is formed between the filling port receiving portions 43a,43b and the vehicle body 1 (center pillar inner panel 32), and the filler injected from the filling ports 32b,32c flows downward.

As shown in fig. 1, the portions 44a and 44b that are difficult to fill with the filler injected from the filling ports 32c and 32 c. The hard-to- fill portions 44a and 44b are formed by the upper rear end portion of the rear first filling space 30a and the upper front end portion of the front second filling space 30 b. In the difficult-to- fill portions 44a,44b, the filling port receiving portions 43a,43b and the covering portions 42a,42b constitute: the filler injected from the filling ports 32c,32c flows along the filling port receiving portions 43a,43b and the covering portions 42a,42b in the directions of arrows f, g.

As shown in fig. 3, the guide portions 45a and 45b are wall portions for guiding the filler injected from the filling ports 32b and 32c downward. The guide portions 45a,45b are configured to: the filler ports 32b,32c are disposed on the vehicle width direction outer sides of the filler ports 32b,32c so as to face each other with the filler space 30 interposed therebetween, and cover the filler ports 32b,32c from the vehicle width direction outer sides.

As shown in fig. 3, the guide portions 45a,45b are formed so as to face downward from the lower surfaces of the covering portions 42a,42b, and support the covering portions 42a,42b from below. The guide portions 45a,45b are formed so as to extend from the lower surfaces of the covering portions 42a,42b to the vehicle width direction outer side ends of the filler port receiving portions 43a,43 b. Therefore, the guide portions 45a,45b also function as reinforcing members for reinforcing the covering portions 42a,42b and the filling-port receiving portions 43a, 43.

As shown in fig. 3 and 4, the stepped portion 45c is a portion for reinforcing the front guide portion 45 b. The step portion 45c is formed in a stepped shape toward the outside in the vehicle width direction in the guide portion 45b between the filler opening receiving portion 43b and the covering portion 42 b.

As shown in fig. 6 and the like, a projecting piece 46 extending downward from the lower surface of the filling port receiving portion 43b is provided on the lower surface of the filling port receiving portion 43 b. The projecting piece 46 is formed of a plate-like member having a substantially triangular shape, and one side thereof is integrally connected to the lower surface of the filling opening receiving portion 43b and extends downward of the filling opening 41 b. Therefore, as shown in fig. 7, the area of the surface having the plate-shaped projecting piece 46 decreases downward in the vehicle vertical direction.

The angle a0 between the vehicle width inner edge 461 of the projecting piece 46 and the vehicle vertical direction V is 0 °, that is, the vehicle width inner edge 461 is parallel to the vehicle vertical direction V. In contrast, the angle a1 between the vehicle width outer edge 462 and the vehicle vertical direction V is about 30 °, and the angle a0 between the vehicle width inner edge 461 and the vehicle vertical direction V is smaller than the angle a1 between the vehicle width outer edge 462 and the vehicle vertical direction V.

The projecting piece 46 is disposed so as to face in the vehicle front-rear direction, that is, so that the face having the plate-shaped projecting piece 46 is parallel to the vehicle width direction. As shown in fig. 4, the lower end portion of the projecting piece 46 is spaced apart from the upper surface 21b of the rocker reinforcement plate (rocker outer panel 21) with a space formed therebetween. Therefore, the lower end of the projecting piece 46 is arranged at a position higher than the lower end of a projecting piece 48a described later. As shown in fig. 6, the projecting piece 46 is disposed at a position further toward the vehicle front-rear direction outer side than a projecting piece 48a described later (further toward the front side than the front-rear direction center).

As shown in fig. 3 and 4, the recessed portions 47 and 48 are formed by hollow protruding portions that are recessed downward and protrude downward from a part of the main body portion 40. The lower surface of the rear recess 47 (the front end surface of the container-shaped projection) is in close contact with the upper surface 21 b. A locking portion 47a is provided on the lower surface of the recessed portion 47 so as to protrude downward, and the locking portion 47a is engaged with and attached to an attachment hole 21d (see fig. 7) of the rocker outer panel 21.

The lower surface of the front recess 48 (the front end surface of the hollow protrusion, that is, the lower end surface) is constituted by an inclined surface parallel to the upper surface portion 21 b. A projecting piece 48a that abuts the upper surface portion 21b of the rocker outer panel 21 is provided on the lower surface of the recessed portion 48. The projecting piece 48a is formed in a plate shape, and the projecting piece 48a is disposed so as to face in the vehicle width direction, that is, so that the face having the plate-shaped projecting piece 48a is parallel to the front-rear direction of the vehicle. As shown in fig. 6, the projecting pieces 46 and 48a are arranged such that: an extension L1 of the face having the plate-shaped projecting piece 46 intersects with an extension L2 of the face having the plate-shaped projecting piece 48 a.

As shown in fig. 3 and 4, the folded portion 40a is a resin hinge portion that is formed in the center pillar inner panel 32 to reduce the space member 4 so as to be folded into a shape that can pass through the opening portion 32 a. As shown in fig. 4, the folded portion 40a is formed of a groove formed in a semicircular shape (U shape) in a side view. The folded portion 40a is formed in a thin-walled shape so as to be able to fold the partition member 4 into two in the front-rear direction at this position.

As shown in fig. 3, a vehicle width direction inside cutout groove 40c is formed on the vehicle width direction inside of the folded portion 40 a. A vehicle width direction outer cutout groove 40d is formed on the vehicle width direction outer side of the folded portion 40 a. The partition member 4 is configured to be easily bent and deformed by the folded portion 40a, the vehicle width direction inside cutout groove 40c, and the vehicle width direction outside cutout groove 40 d.

As shown in fig. 6, the vehicle width direction outer cutout groove 40d has a lateral groove 40e and a front-rear groove 40 g. The lateral groove 40e is formed by a groove having a shape in which the outer end of the folded portion 40a in the vehicle width direction is cut. The front-rear groove 40g is formed in a shape that is notched in the front-rear direction from the center position of the lateral groove 40e in the vehicle width direction.

The swinging portion 40b allows the bent portion 49 to swing, and the bent portion 49 closes a gap with the inner wall of the pillar stiffener 33. As shown in fig. 7, the swing portion 40b is formed of a groove formed in an arc shape (semicircular shape) in a cross section cut in a direction orthogonal to the longitudinal direction of the spacer member 4. The swing portion 40b extends in the front-rear direction at a portion on the vehicle width direction outer side of the main body portion 40. As shown in fig. 5 and 6, a rear cutout groove 40h and a front cutout groove 40i are formed in the front and rear end portions of the swing portion 40 b. A vehicle width direction outer cutout groove 40d is formed in a central portion of the swing portion 40b in the front-rear direction.

According to the above configuration, the bent portion 49 formed on the vehicle width direction outer side of the swing portion 40b can be easily elastically deformed in the vertical direction by the swing portion 40b, the rear cutout groove 40h, the front cutout groove 40i, and the vehicle width direction outer cutout groove 40 d. The bent portion 49 is constituted by: and elastically deforms by coming into contact with the wall surface of the pillar reinforcement 33, and eliminates the gap with the wall surface. The curved portion 49 has a cross-sectional shape orthogonal to the front-rear direction curved in an arc shape.

As shown in fig. 6 and the like, the regulating mechanism 49a is constituted by a projecting piece for regulating the bending angle of the swinging portion 40 b. The regulating mechanism 49a projects downward along the recessed portion 47 from the lower surface of the base end portion (vehicle width direction inner end portion) of the curved portion 49 in the front view. The regulating mechanism 49a is disposed at a position near the reinforcing projection piece 40j so as to be orthogonal to the latter in a bottom view. Therefore, when the bending portion 49 rotates downward about the swing portion 40b, the regulating mechanism 49a abuts against the reinforcing projection piece 40j, and further rotation of the bending portion 49 is suppressed.

As shown in fig. 1, the filling openings 41a and 41b (see fig. 3) formed integrally with the main body 40 so as to face the filling ports 32b and 32c are formed so that the filler injected from the filling ports 32b and 32c flows toward the hard-to- fill portions 44a and 44b (the directions of arrows f and g shown in fig. 4) in the filling space 30. The filling opening portions 41a,41b are formed by filling port receiving portions 43a,43b and covering portions 42a,42b arranged so as to surround the filling ports 32b,32c formed in the center pillar 3 (the vehicle body frame 10). The rear filling opening 41a is formed behind the lower end of the opening 32 a. The front filling opening 41b is formed in front of the lower end of the opening 32 a.

According to the present embodiment, the following effects are obtained.

In the present embodiment, the vehicle body side portion structure a includes the spacer member 4, the spacer member 4 is disposed on the upper side of the rocker reinforcement panel (rocker outer panel 21), and has the filling openings 41a,41b facing the filling ports 32b,32c and the integrated body 40, the filling space 30 extending in the front-rear direction is formed between the spacer member 4 and the center pillar reinforcement panel 33 constituting a part of the center pillar 3, and the spacer member 4 includes the projecting piece 46 as the first rib extending downward of the filling openings 41a,41 b.

Thus, since the filling openings 41a,41b of the spacer member 4 are provided with the projecting pieces 46 extending downward, the portions near the filling openings 32b,32c of the spacer member 4 can be suppressed from sinking in the vertical direction. Therefore, a gap can be prevented from being generated in this portion, and thus the sound insulating performance can be improved.

In the present embodiment, the partition member 4 has a plurality of tubular recessed portions 47,48 formed by partially recessing the body portion 40 downward, the lower end portion of one recessed portion 47 has a locking portion 47a as a fixing portion to the rocker 2, the lower end portion of the other recessed portion 48 has a projecting piece 48a as a second rib, and the projecting piece 46 is disposed further outward in the vehicle longitudinal direction than the projecting piece 48 a.

Thus, the end of the spacer member 4 that cannot be completely supported by the locking portion 47a and the projecting piece 48a can be supported by the projecting piece 46, and thus, the end can be prevented from sagging.

In the present embodiment, the projecting piece 46 and the projecting piece 48a are formed in a plate shape, and are arranged such that an extension line L1 of the projecting piece 46 and an extension line L2 of the projecting piece 48a intersect in a plan view. This prevents the spacer member 4 from sinking downward even when any one of the projecting piece 46 and the projecting piece 48a slides.

In the present embodiment, the projecting piece 46 is formed to face in the vehicle front-rear direction, and the projecting piece 48a is formed to face in the vehicle width direction. Thus, even when one of the projecting piece 46 and the projecting piece 48a is deformed or slides, the other can prevent the spacer member 4 from sinking. Further, since the projecting piece 46 has a width in the vehicle width direction, sinking can be effectively prevented from occurring when the foaming agent is injected.

In the present embodiment, the lower end of the projecting piece 46 is arranged at a position higher than the lower end of the projecting piece 48 a. Accordingly, since the length of the projecting piece 46 in the vertical direction is formed shorter than the length of the projecting piece 48a, the portion of the spacer 4 near the filling ports 32b and 32c can be suppressed from sinking downward without lowering the workability of installing the spacer 4. Further, since a space is formed below the projecting piece 46, the foaming agent can be filled into the vehicle longitudinal direction end portion of the filling space 30.

In the present embodiment, the projecting piece 46 extends downward at a distance from the rocker reinforcement plate (rocker outer panel 21). This can suppress the downward sinking of the portions of the spacer member 4 near the filling ports 32b,32c, without reducing the workability of disposing the spacer member 4. Further, since a space is formed below the projecting piece 46, the foaming agent can be filled into the vehicle longitudinal direction end portion of the filling space 30.

In the present embodiment, the area of the projecting piece 46 and the area of the projecting piece 48a are respectively reduced toward the vehicle vertical direction lower side, and the angle a0 formed by the vehicle width inner edge 461 of the projecting piece 46a and the vehicle vertical direction V is formed smaller than the angle a1 formed by the vehicle width outer edge 462 and the vehicle vertical direction V.

This can suppress a decrease in the fluidity of the foaming agent as a filler filled in the filling space 30, and can suppress the portions of the spacer member 4 near the filling ports 32b and 32c from sinking downward. By setting the angle of the vehicle width inner edge 461 of the projecting piece 46 small, the load generated by the foaming agent touching the filling openings 41a,41b can be supported, and the sagging of the portions of the spacer member 4 near the filling openings 32b,32c can be suppressed.

In the present embodiment, the filling opening portions 41a and 41b of the spacer member 4 are formed by the filling opening receiving portions 43a and 43b and the guide portions 45a and 45b connecting the covering portions 42a and 42b, and the projecting piece 46 extends downward from the filling opening receiving portions 43a and 43 b. Thus, the load of the foaming agent applied to the filling port receiving portions 43a,43b when the foaming agent as the filler is injected can be supported by the projecting pieces 46, and the sagging of the portions of the spacer member 4 in the vicinity of the filling opening portions 41a,41b can be suppressed.

The present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within a range that can achieve the object of the present invention are included in the present invention.

For example, in the present embodiment, the filling space 30 extending in the front-rear direction is formed between the spacer member 4 and the center pillar reinforcement plate 33 constituting a part of the center pillar 3, but the present invention is not limited to this structure. For example, the filling space may extend in the front-rear direction and may extend in another direction.
