A discharged air flow path connected to a cooling fan has a first discharged air flow path which is connected to at least one side trim of a left side trim and a right side trim and a second discharged air flow path which branches off from the first discharged air flow path and which is connected to the side trim. A first connecting portion which connects the first discharged air flow path and the side trim is disposed so as to be spaced away from a second connecting portion which connects the second discharged air flow path and the side trim in a front-rear direction. The first discharged air flow path and the second discharged air flow path discharge air into a passenger compartment by way of the side trim.
