ABSTRACT:
A booster of the present invention is structured to include one permanent magnet (first permanent magnet)40provided in an input rod20, and the other permanent magnet (second permanent magnet)51forming a repulsive magnetic field between the second permanent magnet51and the first permanent magnet40, and to apply a force amplified by a force received by the second permanent magnet51to an output rod60through a channel different from an output applying channel by an output applying member30to 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.
