A vehicle hood includes an outer panel, an inner panel, and a deformable part that deforms with the outer panel when the outer panel deforms toward the inner panel, in which the inner panel includes a bottom, an upright wall, and an opposed part, and the deformable part includes a joint part joined to an intermediate wall of the upright wall or the opposed part, and a displaceable part that is close to or in contact with the outer panel above the bottom and is capable of being downward displaced with the outer panel to below the joint part when the outer panel deforms toward the inner panel. ## Claims ### Claim 1 A vehicle hood comprising: an outer panel; an inner panel disposed below the outer panel; and a deformable part that is joined to the inner panel and deforms with the outer panel when the outer panel deforms toward the inner panel, wherein the inner panel includes a bottom, an upright wall rising from the bottom toward the outer panel, and an opposed part that is connected to an upper end of the upright wall and is opposed to the outer panel, wherein the deformable part includes a joint part joined to an intermediate wall of the upright wall, the intermediate wall being located between a lower end and the upper end of the upright wall, or joined to the opposed part, and a displaceable part that is close to the outer panel above the bottom and capable of being downward displaced with the outer panel to below the joint part when the outer panel deforms toward the inner panel. ### Claim 2 (depends on 1) The vehicle hood according to claim 1, wherein: the joint part is joined to the intermediate wall; and the displaceable part has a shape bent to be convex upward and is invertible so as to be convex downward while being downward displaced with the outer panel to below the joint part. ### Claim 3 (depends on 2) The vehicle hood according to claim 2, wherein a dimension between the bottom and the intermediate wall in a vertical direction is set to ½ or more of a dimension between the bottom and the opposed part in the vertical direction. ### Claim 4 (depends on 2) The vehicle hood according to claim 2, wherein: the upright wall includes a lower vertical wall connecting the bottom and the intermediate wall, and an upper vertical wall connecting the intermediate wall and the opposed part; the intermediate wall is flat and intersects with both the lower vertical wall and the upper vertical wall; the deformable part is made up of a component different from the inner panel; the joint part is flat; the displaceable part includes an inclined part that is flat and connected to the joint part, and is inclined so as to approach the outer panel as being more away from the joint part in a direction from the intermediate wall to the bottom in parallel with the intermediate wall; and an angle defined by the joint part and the inclined part is an obtuse angle. ### Claim 5 (depends on 4) The vehicle hood according to claim 4, wherein an angle defined by the joint part and the inclined part is 135° to 180°. ### Claim 6 (depends on 1) The vehicle hood according to claim 1, wherein: the bottom, the upright wall, and the opposed part each have a shape extending in a vehicle front-back direction in a side portion in a vehicle width direction of the inner panel; and the deformable part has a shape extending along the vehicle front-back direction. ### Claim 7 (depends on 6) The vehicle hood according to claim 6, wherein the displaceable part has a high-stiffness part having stiffness higher than stiffness of any other portion of the displaceable part, and has a shape that continuously runs to extend along the vehicle front-back direction. ### Claim 8 (depends on 7) The vehicle hood according to claim 7, wherein the high-stiffness part has a shape that is recessed from another portion of the displaceable part so as to be convex downward.
