A mechanism for the attachment of a speed sensor to a vehicle comprising a rotary body for attachment to an end of a wheel axle such that the rotary body rotates with the wheel axle, the rotary body having an outer peripheral surface, the outer peripheral surface having a gear wheel with teeth; a sensor mounting body within which the rotary body rotates by means of a bearing therebetween; a speed sensor attached to the sensor mounting body and aligned opposite to the gear wheel with teeth of the rotary body, the bearing maintaining a predetermined gap between the speed sensor and the gear wheel with teeth, the teeth providing the change in magnetic field sensed by the speed sensor when the rotary body is rotating with the wheel axle so that the speed sensor generates a signal corresponding to the rotational speed of the wheel axle; and a connection link through which the sensor mounting body is connected to a frame of the vehicle.
