Abstract: Instrument panel side parts are provided integrally with an instrument panel main body part. Vehicle-mounted components are housed in the instrument panel side parts. Thus, even in a vehicle in which an engine compartment is not provided on a vehicle front side in a vehicle cabin it is possible to ensure a housing space for these vehicle mounting parts. Further, the instrument panel side parts are provided integrally with the instrument panel main body part. Thus, compared to a case in which the instrument panel side parts are separated from the instrument panel main body part, a space around the driver's seat can be expanded by the reduced amount of dead space, and the comfortability of the driver can be ensured.
