PURPOSE: A car wheel speed sensor is provided to reduce errors of wheel speed measurement and to accurately measure wheel speed. CONSTITUTION: A car wheel speed sensor (10) includes a magnet (100), a measurement unit (200), a pole piece (300), a terminal (400), and an insert (500). The magnet generates a magnetic field. The measurement unit is arranged between a measured body and the magnet, and detects the change of the magnet field which is generated by the rotation of the measured body. The pole piece is arranged in between the magnet and the measurement unit. The terminal delivers a signal which is generated in the measurement unit to the outside. The insert is mounted with the magnet, the measurement unit, the pole piece, and the terminal. |
