The present invention provides a method for producing a joined body of different materials, which may easily achieve joining between a plurality of resin layers and joining between a resin and a metal, and a joined body of different materials.

Method for producing joined body of different materials and joined body of different materials

Provided is versine trolley-type equipment for inspecting a track irregularity, having sensors respectively provided to a trolley so as to measure a height difference, direction misalignment, gauge irregularity, rail longitudinal slope, cant and the like of railroad rails, and simultaneously measuring the height difference and direction misalignment of a left rail and a right rail so as to reduce a measurement time by half and, also, allowing left and right measurement frames to freely move in a vertical direction within a predetermined range, thereby bringing front and rear trolley wheels of the left and right measurement frames into close contact with the rails all the time even if the rails are warped.
