Abstract
A device for applying a load to a rotating shaft of an exercise bicycle which receives the load. When a user places his/her feet on the pedals of the exercise bicycle and bends and stretches his/her legs, the transmission gear of a speed increasing mechanism of the exercise bicycle is rotated by the paddles and thereby, a rotor coupled by a bearing to a fixed main shaft of the load applying device is rotated with respect to the main shaft. The rotor is a magnetic conductor. A magnetic field is provided so that the rotor is passed through a beam-like magnetic flux path produced thereby. When the rotor is rotated, the rotor cuts the magnetic field and thereby produces an induced eddy current, causing an eddy current break effect to the rotor. In this way, the load applying device can apply a load to the user who rides on the exercise bicycle. A first and a second pawl-type electromagnet are respectively used as a first and a second pole thereof. The rotor is mounted between the first and second poles of the electromagnet.
