To provide a structural body to be used as a component for a mud removing device for simply and easily removing mud stuck to a tire without needing any motive forces or as a component for a small paved road or a small bridge.

A structure 1 is constructed in such a manner that in at least a part inside a frame main body 2 connectable in a forward/backward direction and having required length and width, twist providing members 10, 10,..., for providing twisting to a vehicle tire traveling on the frame main body 2 and removing mud stuck in a tire groove or the like are disposed by using the front or rear side frame member 3 or 4 of the frame main body 4 as a reference, by preferably an attaching angle of 65 to 75° and by a required gap, and in the center of the frame main body 2, projections 9, 9,..., engaged with the tire to remove the mud stuck to the tire and provide a straight advancing characteristic are disposed in a forward/backward direction by a required interval.
