置としたことを特徴とする渦電流式回転計。a permanent magnet that rotates together with a rotating shaft that is rotatably attached to a box; and an induction board that is rotatably disposed near and opposite the permanent magnet around the axis of the rotating shaft; a pointer attached to the induction board, the rotation of the permanent magnet causes the induction board to generate a rotational torque proportional to the number of rotations thereof to drive the pointer, and the magnetic field created by the permanent magnet drives the box. In an eddy current tachometer that turns on and off a reed switch placed near the permanent magnet inside the body, the permanent magnet has magnetic poles arranged along the circumference of its surface, and adjacent magnetic poles An eddy current type tachometer characterized by a magnetic pole arrangement in which the magnetic field generated by a portion of the reed switch does not activate the reed switch.
