<P>PROBLEM TO BE SOLVED: To provide a negative pressure feeder to feed the negative pressure to a pneumatic assistor capable of saving a space, reducing the number of components, and enhancing the mounting workability and the mounting strength. <P>SOLUTION: A synthetic resin-made body case part 28, an upper cap part 29 and a lower cap part 30 are welded to each other to form a reservoir ejector unit 1 with a reservoir tank 4 integrated with an ejector 5, and the reservoir ejector unit 1 is mounted on a master cylinder body 20. When a master cylinder 3 is mounted on a pneumatic assistor 2, a connection pipe 37 of the ejector 5 is fitted to a grommet 36 of a negative pressure port 35 of the pneumatic assistor 2. By integrating the ejector 5 with the reservoir tank 4, the space can be saved, the number of components can be reduced, and the mounting workability and the mounting strength can be enhanced. <P>COPYRIGHT: (C)2007,JPO&INPIT |
