1. An estimation device for estimating a friction coefficient of a road surface, the estimation device comprising:
a sensor configured to detect a force acting on a wheel;
a moment calculator configured to calculate a moment around a vertical axis at a center of a ground contact load of a tire of the wheel on a basis of an output of the sensor; and
a friction coefficient estimator configured to estimate the friction coefficient of the road surface with which the tire is in contact, on a basis of the moment.
