## Abstract

The present disclosure provides a body structure for a vehicle capable of improving a vibration damping effect by a damping member while preventing an increase in an application amount of the damping member and a shape change of a component. Embodiments include a body structure for a vehicle in which a first bonded surface of a first body component and a second bonded surface of a second body component are bonded via a damping member, with which a portion between the first bonded surface and the second bonded surface is filled. The first bonded surface of the first body component has a vertical wall extending toward the second bonded surface or away from the second bonded surface. The portion between the first bonded surface and the second bonded surface is filled with the damping member such that the damping member contacts the vertical wall.

## Claims

### Claim 1

A body structure for a vehicle, the body structure comprising a first body component having a first bonded surface; and a second body component having a second bonded surface opposing the first bonded surface, wherein
the first bonded surface and the second bonded surface are bonded via a damping member with which a portion between the first bonded surface and the second bonded surface is filled,
the first bonded surface has a vertical wall that extends in a direction separating from the second bonded surface,
the portion between the first bonded surface and the second bonded surface is filled with the damping member such that the damping member contacts the vertical wall,
the first bonded surface has a recessed section that is recessed in the direction separating from the second bonded surface, the recessed section comprising a circumferential wall having a closed shape and a top wall that closes an opening edge of the circumferential wall and extends along the second bonded surface,
the vertical wall is an inner circumferential surface of the circumferential wall and continues in a circumferential direction of the recessed section, and
the recessed section is filled with the damping member, which contacts the vertical wall.

### Claim 2 (depends on 1)

The body structure for a vehicle according to claim 1,
wherein the first body component has a plate-shaped member, a surface of which on one side serves as the first bonded surface, and
the plate-shaped member has a projected section, a surface of which on the one side is recessed and a surface of which on another side is projected, and the recessed section is thereby formed in the first bonded surface by the projected section.

### Claim 3 (depends on 1)

The body structure for a vehicle according to claim 1,
wherein the recessed section has a shape, an aspect ratio of which falls within a range of 0.5 to 2.0 when seen in a normal direction of the first bonded surface.

### Claim 4 (depends on 3)

The body structure for a vehicle according to claim 3,
wherein the recessed section has a circular shape when seen in the normal direction of the first bonded surface.

### Claim 5 (depends on 1)

The body structure for a vehicle according to claim 1,
wherein the vertical wall is inclined at 16 to 100 degrees with respect to the first bonded surface.

### Claim 6 (depends on 1)

The body structure for a vehicle according to claim 1,
wherein the damping member is viscoelastic.

### Claim 7 (depends on 1)

The body structure for a vehicle according to claim 1,
wherein the damping member has a loss factor of 0.2 or higher and a storage modulus of 100 MPa or higher under conditions of 20° C. and 60 Hz.

### Claim 8 (depends on 1)

The body structure for a vehicle according to claim 1,
wherein one of the first body component and the second body component is a joint member having a flat surface section,
the other of the first body component and the second body component is a hollow member having an inner circumferential surface with a space section in which the joint member can be inserted, and
a portion between the flat surface section and the inner circumferential surface as the first bonded surface and the second bonded surface is filled with the damping member such that the damping member contacts the vertical wall.

### Claim 9 (depends on 1)

The body structure for a vehicle according to claim 1,
wherein the first body component has a hat cross-sectional shape having a brim section as the first bonded surface,
the second body component has a flat surface as the second bonded surface that is made to overlap the brim section via the damping member, and
the vertical wall is disposed in the brim section.

### Claim 10 (depends on 2)

The body structure for a vehicle according to claim 2,
wherein the recessed section has a shape, an aspect ratio of which falls within a range of 0.5 to 2.0 when seen in a normal direction of the first bonded surface.
