Blower unit mounting structure and method for mounting a blower unit

An instrument panel (2) is formed in such a manner as to be vertically divided into an upper panel (12) and a lower panel (13) along a transverse direction of the body of a vehicle. A steering support beam (5) and a blower unit (7) are integrally mounted on the lower panel (13) to construct a unitized component before they are mounted on the vehicle body. After the unitized component is mounted on the vehicle body (1) from an upper side of the lower panel (13), the upper panel (12) is mounted on the vehicle body (1).
