Measuring device for measuring the path and/or speed of a moving object in relation to a structural component, with a measuring wheel ( 20 ) and with a rotary encoder ( 10 ), such that the measuring wheel ( 20 ) is coupled to the encoder shaft ( 16 ) of the rotary encoder ( 10 ) at a precise angle of rotation, and the measuring wheel ( 20 ), along with the contact surface ( 22 ) formed by its jacket, can be positioned on the object in such a way that the axis of the measuring wheel (X direction) runs basically perpendicular to the direction of motion (Z direction) of the object, and the measuring wheel ( 20 ) and the rotary encoder ( 10 ) are elastically mounted on the structural component in a direction (Y direction) that is basically perpendicular to the axis of the measuring wheel (X direction) and to the direction of motion of the object (Z direction), wherein the measuring wheel ( 20 ) and the rotary encoder ( 10 ) are positioned on an elastic arm ( 32 ) that exhibits two legs ( 34, 36 ), the elastic arm ( 32 ) is secured to the structural component with the end of one of the legs ( 34 ), the measuring wheel ( 20 ) and the rotary encoder ( 10 ) are attached to the end of the other leg ( 36 ), and one of the legs ( 34 ) can be deflected in what is essentially the Y direction and the other leg ( 36 ) can be deflected in what is essentially the X direction.
