Abstract
A booster of the present invention is structured to include one permanent magnet (first permanent magnet) 40 provided in an input rod 20, and the other permanent magnet (second permanent magnet) 51 forming a repulsive magnetic field between the second permanent magnet 51 and the first permanent magnet 40, and to apply a force amplified by a force received by the second permanent magnet 51 to an output rod 60 through a channel different from an output applying channel by an output applying member 30 to 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.
