To provide a cold/warm air outlet assembly for construction a machine, said assembly being capable of fully meeting desires on the comfort of a working environment of an operator under air conditioning and use of air conditioning for a multiplicity of purposes, an upper outlet tube and lower outlet tube are formed into substantially tubular shapes having conical circumferential walls with walls, through which air outlets are formed, being included as tilted walls. The upper outlet tube is resiliently fitted and connected to the lower outlet tube and the lower outlet tube is resiliently fitted and connected to a vertical part of an air conditioner duct The upper and lower outlet tubes are, therefore, turnable in horizontal direction at their connected parts. By operating air-direction control knobs arranged in the air outlets directed toward desired turned positions, the vertical directions of the internal fins can be adjusted to cause cold/warm air to blow out in the desired directions, respectively.
