A rotating body load measuring device according to the present invention includes: a first support section which supports one end portion of a shaft body, which protrudes from one end face of a rotating body, so as to be immovable in a first direction and a second direction along a central axis; a second support section which supports the other end portion of the shaft body, which protrudes from the other end face of the rotating body, so as to be immovable in the first direction and movable in the second direction; and a measuring part capable of measuring a force acting in the first direction on at least one of the first support section and the second support section from the shaft body and capable of measuring a force acting in the second direction on the first support section from the shaft body.

A tire balance measurement device includes a rotation drive portion, an eccentric force measurement unit, a calculation unit, and an evaluation unit. The eccentric force measurement unit measures an eccentric force generated in a main shaft. The calculation unit calculates an eccentric amount of the main shaft based on the eccentric force measured by the eccentric force measurement unit. The evaluation unit evaluates the eccentric amount of the main shaft based on a correlation between the eccentric force measured by the eccentric force measurement unit when the main shaft is rotated at a predetermined rotation speed, and the rotation speed.
