PROBLEM TO BE SOLVED: To provide a screed apparatus of a paving construction machine, obtaining enough expansion stroke of an expansible screed to a main screed. SOLUTION: In one side and the other side support mechanisms 24, 25, one side the other side screeds 22, 23 are supported on the main screed to respectively project from one side and the other side of the main screed 21 in the expanding direction. The one side and other side support mechanisms 24, 25 are so constructed that a plurality of main guide shafts 41 are fitted to freely slide in the expanding direction over the full length to holders 33 provided in fixed positions in the expanding direction of one side and the other side of the main screed 21. The plurality of main guide shafts 41 and a plurality of hollow expansion side guide shafts 43 whose outer ends are opened are provided in parallel and integral with each other, and the one side and other side expansible screeds 22, 23 are integrated with telescopic rods 48, 49 fitted to the plurality of expansible side guide shafts 43 extending from the outer ends to the interiors to respectively freely slide in the expanding direction.
