A magnetostrictive torque sensor includes a magnetostrictive portion formed on a rotational shaft, a bobbin surrounding an outer circumference of the magnetostrictive portion, and a coil wound on the bobbin for detecting a change in magnetic property of the magnetostrictive portion. The bobbin fits over the magnetostrictive portion in contact with the magnetostrictive portion in such a manner as to allow rotation of the magnetostrictive portion relative to the bobbin. The magnetostrictive torque sensor is carried on an electrically assisted bicycle or an electric power steering apparatus of a vehicle.

Provided is a motorcycle navigation apparatus that receives broadcasts from a satellite radio mounted on a motorcycle. The motorcycle navigation apparatus includes a controller, monitor and a screen switching unit. The controller is configured to control the navigation apparatus. The a monitor configured to provide, when said satellite radio receives a warning, a notification that information has been received by said satellite radio. The screen switching unit configured to switch said navigation screen to a screen that corresponds to the received information when an operator executes a predetermined operation on the controller, wherein the predetermined operation is executed upon receipt of said notification.

Navigation apparatus for motorcycle

A power-assisted bicycle with an auxiliary power unit that improves positional stability of a torque sensor and inhibits the position of the sensor from being misaligned, wherein the power-assisted bicycle includes an annular hollow member inserted over an outer periphery of a crankshaft and a one-way clutch disposed on the hollow member for transmitting, when a pedaling torque in a direction in which the power-assisted bicycle traveling in a forward direction, is applied to the crankshaft, and wherein a magnetic film is formed in a recess disposed in an outer periphery of the hollow member, and a magnetostrictive torque sensor is positioned and fixed by a support member for rotatably supporting the magnetostrictive torque sensor relative to the annular hollow member at both ends of the recess, such that the magnetostrictive torque sensor faces the magnetic film in the recess.
