A metal sintered body composite material which can exhibit superior seizure resistance even when light metal is softened, and a method for producing the same. The production method uses iron base raw material powder including C and one of Cr, Mo, V, W, Mn, and Si, and comprises the steps of forming and sintering a powder compressed article so as to obtain a porous metal sintered body having a space lattice structure having pores, impregnating the pores of the porous metal sintered body with an aluminum alloy and solidifying the aluminum alloy, applying aging treatment by heating and holding the composite material at an aging treatment temperature range, whereby a metal constituting the porous metal sintered body has a micro-Vickers hardness of 200 to 800.

A mounting structure of a roof duct in an air conditioner which comprises a top surface of the roof duct having an air diffuser and formed with a grooved recess along the longitudinal direction of the roof duct, a trough-shaped reinforcement mounted at both ends thereof on an automotive body engaged with the grooved recess, a swelled part partly swelled on the bottom of the reinforcement and formed on the bottom in reverse direction to the grooved recess, and a wire harness connected to a control switch and inserted into the space formed between the bottom of the grooved recess and the swelled part of the reinforcement. Thus, this mounting structure can obtain a passage of a wire harness out of the roof duct, thereby reducing the resistance of ventilation of air through the roof duct. Further, this mounting structure can use a reinforcement as a fixture of a wire harness and a protector, thereby reducing the abnormal noise from the roof duct, can reduce the number and weight of components to be mounted in the roof duct and can facilitate the mounting of the roof duct on the roof.
