An apparatus of for measuring roughness of a road surface such as convex, concave or inclination is to be mounted on the vehicle. The apparatus comprises a rotation driving member for generating rotation motion in vertical plane and for outputting a signal concerning its rotation angle. An inclinometer is provided to detect an inclined angle of the rotation driving member. A distance measuring member for measuring distance from road surface as being rotated by the rotation motion from said rotation driving member. A processing unit calculates a vertical distance and a horizontal distance between the apparatus and the road surface by means of the inclined angle detected by the inclinometer and the rotation angle detected by the rotation driving member.

Apparatus for measuring a shape of road surface

A concrete-floor finisher includes a plurality of rotary shafts (28) supported on a supporting plate (2) of a machine proper (1) so as to be tiltable in x and y directions and rotatable opposite to each other, and a plurality of blades (12a to 12d) radially arranged relative to a rotor (10) at the lower part of each of the rotary shafts and respectively held in place by a plurality of fitting members (13), and a rocking supporting unit (14) for the fitting member of each blade is composed of a fixed plate (15) attached to the upper surface of the blade, a holding member (16) attached to the vertical plate portion of the fixed plate, a bearing (18) pivotally supporting substantially the central portion of the holding member (16) by a supporting pin (17) extended in the tangential direction of the circle of rotation, and means for fitting a square cylindrical portion (19) of the bearing onto the forward end of the fitting member and removably fixing in place with a bolt (21) or the like, thus ensuring 20.degree. freedom of vertical rocking movement for each of the blades and thereby bringing the blades into parallel contact with the concrete.
