Abstract
A booster of the present invention is structured to include one permanent magnet (first permanent magnet)provided in an input rod, and the other permanent magnet (second permanent magnet)forming a repulsive magnetic field between the second permanent magnetand the first permanent magnet, and to apply a force amplified by a force received by the second permanent magnetto an output rodthrough a channel different from an output applying channel by an output applying memberto booster the inputted force. The booster can boost a force by applying a force to operate an inputting member without requiring such a negative pressure source or a hydraulic pressure source operated by a separate driving force different from a driving force to drive the inputting member as the conventional booster requires.
