Abstract
A rotation transmission device includes a one-way clutch which is provided between an output shaft of a speed increaser and an input shaft of a generator, which makes a connection between the output shaft and the input shaft to be rotatable integrally in a state in which a rotation speed of the output shaft is higher than that of the input shaft, and which cuts off the connection between the output shaft and the input shaft in a state in which the rotation speed of the output shaft is lower than that of the input shaft. The rotation transmission device further includes: a measurement section which measures a state of the one-way clutch which changes depending on a load exerted to the one-way clutch; and an acquisition section which acquires the load exerted to the one-way clutch on a basis of a measurement result of the measurement section.
