PURPOSE: A rotational sensor device is provided to reduce manufacturing costs of the sensor device, and to conveniently and easily change a location of a flange plate even though a position of a bolt hole on an engine block is changed. CONSTITUTION: A rotational sensor device comprises the following: a main body(1) in which a magnetic resistance element(10,11) and a permanent magnet(12) are built to detect rotation speed of a rotary body which is connected to a crankshaft; a thermally melted part fixed on the circumference of the main body; and a flange plate(2) fixed on the engine block with a bolt. |
