A vehicle on which a power source apparatus is mounted includes the power source apparatus disposed in an in-car space of the vehicle, a cooling apparatus supplying air within the in-car space to the power source apparatus, and a cooling duct which the air discharged from the power source apparatus flows. The cooling duct is connected to any one of a first cooling flow path formed by a pillar of the vehicle, a second cooling flow path formed by a frame portion of the vehicle and a stepped portion provided for the frame portion, and a third cooling flow path formed by the frame portion and a scuff plate portion. ## Claims ### Claim at position 1 1-6. (canceled) ### Claim 7 A vehicle on which a power source apparatus is mounted, comprising: the power source apparatus disposed in an in-car space of the vehicle; a cooling apparatus supplying air within the in-car space to the power source apparatus; a cooling duct which the air discharged from the power source apparatus flows; and a first cooling flow path connected to the cooling duct and formed by a pillar of the vehicle; a second cooling flow path connected to the cooling duct and formed by a vehicle frame formed on each side of a lower portion of the pillar and a stepped portion provided for the vehicle frame; and a third cooling flow path connected to the cooling duct and formed by the vehicle frame and a scuff plate portion provided for the vehicle frame, wherein the first cooling flow path, the second cooling flow path, and the third cooling flow path are coupled to each other through the pillar, and the pillar is directly connected to the cooling duct disposed under a seat mounted in the in-car space between the power source apparatus and the pillar, and wherein the first cooling flow path extends from the lower portion of the pillar to a roof portion of the vehicle, and the air is discharged from the roof portion to the in-car space after the air flows through the first cooling flow path. ### Claim 8 (depends on 7) The vehicle according to claim 7, wherein the lower portion of the pillar is formed to have a width in a front-rear direction of the vehicle, the width being increased from top toward bottom of the vehicle, and the cooling duct is connected to the lower portion of the pillar. ### Claim 9 (depends on 7) The vehicle according to claim 7, wherein the cooling duct includes a first cooling duct connected to the pillar on a left side of the vehicle and a second cooling duct connected to the pillar on a right side of the vehicle. ### Claim 10 A cooling structure for a power source apparatus mounted on a vehicle, comprising: a cooling apparatus supplying air within an in-car space of the vehicle to the power source apparatus; a cooling duct which the air discharged from the power source apparatus flows; a first cooling flow path connected to the cooling duct and formed by a pillar of the vehicle; a second cooling flow path connected to the cooling duct and formed by a vehicle frame formed on each side of a lower portion of the pillar and a stepped portion provided for the vehicle frame; and a third cooling flow path connected to the cooling duct and formed by the vehicle frame and a scuff plate portion provided for the vehicle frame, wherein the first cooling flow path, the second cooling flow path, and the third cooling flow path are coupled to each other through the pillar, and the pillar is directly connected to the cooling duct disposed under a seat mounted in the in-car space between the power source apparatus and the pillar, and wherein the first cooling flow path extends from the lower portion of the pillar to a roof portion of the vehicle, and the air is discharged from the roof portion to the in-car space after the air flows through the first cooling flow path. ### Claim 11 (depends on 8) The vehicle according to claim 8, wherein the cooling duct includes a first cooling duct connected to the pillar on a left side of the vehicle and a second cooling duct connected to the pillar on a right side of the vehicle.
