First and second encoders are fixed to a drive plate and a clutch cover of which the center portions are connected to each other via a connection shaft and which are disposed between, in a transfer path for torque outputted from an engine, a damper and a connecting/disconnecting part of a clutch mechanism of a transmission. At the same time, detection units of first and second sensors are opposed to portions to be detected of the first and second encoders, respectively.

Rotation transfer apparatus provided with torque measuring device

A charger incorporated in a vehicle wheel supporting rolling bearing unit detects an output voltage of an electric generator and calculates a rotation speed of a hub. When a rotation speed of the hub is in a low speed state where a sensor and a wireless communication device are operated by electric power supplied 5 by a battery, a frequency of wireless communication performed between the wireless communication device and a calculator disposed on a vehicle body side is changed according to the rotation speed of the hub or a traveling speed of a vehicle.
