To provide a screed device of construction machinery for pavement, which can suppress an increase in weight for the securement of rigidity by enabling the structural securement of the rigidity of a supporting mechanism.
The one-side expansion screed 22 and the other-side expansion screed 23 are provided on the central main screed 21 in such a manner as to be movable in a widening direction, respectively. The supporting mechanisms 24 and 25 are provided between the one-side and other-side portions of the main screed 21 and the expansion screeds 22 and 23, respectively. In the supporting mechanisms 24 and 25, guide frame bodies 26 are integrally provided in the one-side and other-side portions of the main screed 21, respectively, and width-direction guide shafts 28 are fitted into the guide frame bodies 26 in a such a manner as to be slidable in a width direction, respectively. Height-direction guide shafts 32 are integrally provided along the opposite sides of first supporting frame bodies 31 which are integrally provided from one end of each of the width-direction guide shafts 28 to the other end thereof, respectively. A second supporting frame body 33 is fitted into each of the height-direction guide shafts 32 in such a manner as to be slidable in a height direction, and width-direction guide shafts 34 of the expansion screeds 22 and 23 are slidably fitted into the second supporting frame bodies 33, respectively.
