The cargo room trim includes: a first plate section that includes a resin having an elongation rate which is equal to or greater than 120%, and has: an outward recess recessed from an inner side of the cargo room to an outer side of the cargo room; and an inward recess that is continuous with the outward recess in a front-back direction of the cargo room, and is recessed from the outer side of the cargo room to the inner side of the cargo room; a second plate section disposed along the first plate section; and a sound absorbing material disposed between the first plate section and the second plate section. ## Claims ### Claim 1 A cargo room trim included in a side wall of a cargo room disposed horizontally next to and/or above a rear wheel of a vehicle, the cargo room trim comprising: a first plate section that includes a resin having an elongation rate which is equal to or greater than 120%, and has: an outward recess recessed from an inner side of the cargo room to an outer side of the cargo room; and an inward recess that is continuous with the outward recess in a front-back direction of the cargo room, and is recessed from the outer side of the cargo room to the inner side of the cargo room; a second plate section disposed along the first plate section; and a sound absorbing material disposed between the first plate section and the second plate section, wherein the second plate section has: a facing section that faces the sound absorbing material disposed between the second plate section and the first plate section; and a second supported section that extends from the facing section to the first plate section, and is supported by the first plate section, the first plate section has an insertion-hole section having formed therethrough a hole through which the second supported section is inserted, and the second supported section is supported by the first plate section by being inserted to the hole of the insertion-hole section. ### Claim 2 A cargo room trim included in a side wall of a cargo room disposed horizontally next to and/or above a rear wheel of a vehicle, the cargo room trim comprising: a first plate section that includes a resin having an elongation rate which is equal to or greater than 120%, and has: an outward recess recessed from an inner side of the cargo room to an outer side of the cargo room; and an inward recess that is continuous with the outward recess in a front-back direction of the cargo room, and is recessed from the outer side of the cargo room to the inner side of the cargo room; a second plate section disposed along the first plate section; and a sound absorbing material disposed between the first plate section and the second plate section, wherein the second plate section includes a resin having an elongation rate which is equal to or greater than 120%, and the resins of the first plate section and the second plate section include: polypropylene at a percentage by weight which is equal to or greater than 40and equal to or smaller than 90; polyethylene terephthalate at a percentage by weight which is equal to or greater than 10 and equal to or smaller than 30; and talc at a percentage by weight which is equal to or greater than 0 and equal to or smaller than 10. ### Claim 3 A cargo room trim included in a side wall of a cargo room disposed horizontally next to and/or above a rear wheel of a vehicle, the cargo room trim comprising: a first plate section that includes a resin having an elongation rate which is equal to or greater than 120%, and has: an outward recess recessed from an inner side of the cargo room to an outer side of the cargo room; and an inward recess that is continuous with the outward recess in a front-back direction of the cargo room, and is recessed from the outer side of the cargo room to the inner side of the cargo room; a second plate section disposed along the first plate section; and a sound absorbing material disposed between the first plate section and the second plate section, wherein the second plate section has a protruding section that protrudes in a direction away from the first plate section from a position at which the second plate section contacts the first plate section, and can contact a body panel. ### Claim 4 (depends on 1) The cargo room trim according to claim 1, wherein the second plate section has: a base section; and a covered section that is formed of a material softer than the base section integrally with the base section, faces a body panel, and covers the base section. ### Claim 5 (depends on 1) The cargo room trim according to claim 1, wherein the second plate section has: a facing section that faces the sound absorbing material disposed between the second plate section and the first plate section; and a first supported section that extends from the facing section to the first plate section, and is supported by the first plate section, and a leading end of the first supported section is welded to the first plate section. ### Claim 6 (depends on 2) The cargo room trim according to claim 2, wherein the second plate section has: a facing section that faces the sound absorbing material disposed between the second plate section and the first plate section; and a first supported section that extends from the facing section to the first plate section, and is supported by the first plate section, and a leading end of the first supported section is welded to the first plate section. ### Claim 7 (depends on 3) The cargo room trim according to claim 3, wherein the second plate section has: a facing section that faces the sound absorbing material disposed between the second plate section and the first plate section; and a first supported section that extends from the facing section to the first plate section, and is supported by the first plate section, and a leading end of the first supported section is welded to the first plate section. ### Claim 8 (depends on 1) The cargo room trim according to claim 1, wherein the second plate section includes a resin having an elongation rate which is equal to or greater than 120%, and the resins of the first plate section and the second plate section include: polypropylene at a percentage by weight which is equal to or greater than 40and equal to or smaller than 90; polyethylene terephthalate at a percentage by weight which is equal to or greater than 10 and equal to or smaller than 30; and talc at a percentage by weight which is equal to or greater than 0 and equal to or smaller than 10. ### Claim 9 (depends on 1) The cargo room trim according to claim 1, wherein the second plate section has a protruding section that protrudes in a direction away from the first plate section from a position at which the second plate section contacts the first plate section, and can contact a body panel. ### Claim 10 (depends on 2) The cargo room trim according to claim 2, wherein the second plate section has a protruding section that protrudes in a direction away from the first plate section from a position at which the second plate section contacts the first plate section, and can contact a body panel. ### Claim 11 (depends on 2) The cargo room trim according to claim 2, wherein the second plate section has: a base section; and a covered section that is formed of a material softer than the base section integrally with the base section, faces a body panel, and covers the base section. ### Claim 12 (depends on 3) The cargo room trim according to claim 3, wherein the second plate section has: a base section;
