なわれている。2. Description of the Related Art Generally, in order to detect the wheel speed of a traveling vehicle, a wheel speed sensor attached to each wheel is
Rotation of a rotor that rotates integrally with an axle connected to a wheel is detected. The rotor contains a magnetic material, and a magnetic sensor such as a Hall IC or an MR element is used to detect the rotation of the rotor. However, if a magnetic sensor such as a Hall IC is provided directly on the axle portion of the traveling vehicle, there is a possibility that the stone may be damaged if it is hit by a stone.
It is easy to break the connection between the lead of the Hall IC and the electric wire. Therefore, in the wheel speed sensor, it has been conventionally practiced to mold a detection element such as a Hall IC with a synthetic resin including a connection portion with an electric wire to improve durability.
