Abstract
When an electromagnetic generatorhaving a pendulum structure is mounted on an interior surface of a tire, an equivalent pendulum length l of a pendulumis adjusted such that an integral multiple of a period λ of the pendulum, which is determined by the equivalent pendulum length l of the electromagnetic generator, is not in agreement with both of an integral multiple of a circumferential length L of the tireand a length S of a non-grounded part of the tire, which is obtained by subtracting a ground contact length C from the circumferential length L of the tire, whereby the power generation capacity of the electromagnetic generator mounted on the tire can be improved regardless of the type of the tire.
