Abstract
An engine rotational speed display device includes a rotational speed sensor and a pulse rotor. An engine rotational speed calculating unit is configured to calculate an engine rotational speed by a moving average of a detected value of a crankshaft rotational speed pulse. A display unit is configured to display the engine rotational speed on a meter by electrical processing. When the crankshaft rotational speed pulse is not detected in a detection time equal to or more than a predetermined value, the engine rotational speed calculating unit determines that the engine rotational speed is '0,' and the engine rotational speed of '0' is displayed on the meter.
