PURPOSE: A wheel speed sensor is provided to prevent the generation of an error by elastically supporting a base in a direction of a wheel and adhering a roller to the wheel. CONSTITUTION: A base(100) is combined with a side of a disc of a wheel. A roller(200) is rotated as a wheel is rotated. An encoder(300) is connected with a rotary shaft. The encoder measures a movement distance and a rotation speed of the wheel by measuring the rotation of the roller. An end of a side of a support unit(400) is inserted into a side in the base. An elastic object(500) elastically supports the base in a direction. |
