を特徴とする速度計発電装置。 A magnetic circuit is formed by a core that faces the gear-shaped rotating body through a gap, and the rotational speed of the gear-shaped rotating body is detected by detecting changes in the magnetic resistance of the magnetic circuit due to the rotation of the gear-shaped rotating body. In the speedometer power generation device, one end of the core forming the magnetic circuit is opposed to the tip of a tooth of a gear-shaped rotating body, and the other end is opposed to a flat part on a side surface of the gear-shaped rotating body. Speedometer generator.
