To provide a paved-surface finishing machine, which can also respond to the determination of the width and intervals of ditches by conditions after supply and site conditions and by which the uniformity and linearity of the depth of the ditches and the uniformity, etc. of ditch width are obtained.

The paved-surface finishing machine is composed of a main body frame 1, a rotor attachment 2, a supporter 4 and a driving device 5, and the driving device 5 is constituted of a handle 9, a driving sprocket 10 rotated by the handle, two sprockets to be driven 11, 12 supported by the main body frame 1, a chain 13 wrapped to the driving sprocket and the sprockets to be driven, a chain 14 wrapped to the driving sprocket and the sprockets to be driven, and a moving bar fixed onto the chain 14. A rotor-attachment moving auxiliary device further sliding the rotor attachment 2 in the progressive direction when the rotor attachment 2 is slid to the end-section front place of a road surface and shifting the rotor attachment 2 in an auxiliary manner up to the end-section place of the road surface is installed.
