A load distribution measuring device for vehicles comprising: - load cell sensors that detect an input from a vehicle passing, the load cell sensors being disposed side by side on a road surface on which a vehicle runs; - an operation part that is adapted to generate an actual load distribution from a tyre of a vehicle, the actual load distribution being input into the load cell sensors when a vehicle passed over the load cell sensors, the actual load distribution being generated based on detection values from the load cell sensors; and - an output part that outputs the actual load distribution generated by the operation part, the load cell sensors are arrayed in sensor rows to have an offset, each of the sensor rows has a plurality of the load cell sensors (2,) which have been disposed adjacent at equal intervals along a direction perpendicular to a reference passing direction of a vehicle, each sensor row of the sensor rows being offset, the load cell sensors thereby disposed in the column direction along the reference passing direction DS being arrayed with being displaced by an equal amount of offset in the direction perpendicular to the reference passing direction characterized in that the operation part is adapted to generate the actual load distribution based on the detection values from the load cell sensors, a resolution of the actual load distribution in the direction perpendicular to the passing direction of a vehicle has been enhanced higher than a resolution corresponding to an interval of two load cell sensors; and in that the operation part is adapted to: calculate a passing velocity of a vehicle based on a time difference between singular points in detection waveforms of the load cell sensors disposed with a positional displacement in a reference passing direction of a vehicle; - select detection values in a same input state as an input state in a case where a vehicle passes a operation reference line, the detection values being selected from the detection waveforms from the load cell sensors, respectively, based on a time difference calculated based on the passing velocity and a distance between the operation reference line and each of the load cell sensors in the reference passing direction; - generate a data column of load distribution on the operation reference line, based on a combination of the selected detection values from the load cell sensors; and - repeat the select and generate steps with displacing a position of the operation reference line in the direction of the reference passing direction within a predetermined range larger than the grounding surface of the tyre of a vehicle to generate the actual load distribution. - load cell sensors that detect an input from a vehicle passing, the load cell sensors being disposed side by side on a road surface on which a vehicle runs;
