Abstract: <P>PROBLEM TO BE SOLVED: To ensure an output even under a state that a negative pressure by a negative pressure source is not generated without reducing the output while effectively reducing the surface area of a diaphragm.  <P>SOLUTION: A power piston 8 is constituted of a power piston member 5 and the diaphragm 7. The inner peripheral side bead part 7a of the diaphragm 7 is fitted and attached in/to a fitting part 5d comprising an annular recess which is provided on the outer peripheral side part of the power piston member 5. On the power piston member 5, a communicating hole 5g which communicates a constant pressure chamber 9 with a transforming chamber 10 is provided. In the meantime, an elastic lip 7d which extends from the inner peripheral side bead part 7a is provided on the diaphragm 7, and the lip 7d is normally covers and closes the communicating hole 5g. Then, when the internal pressure of the constant pressure chamber 9 becomes larger than the internal pressure of the transforming chamber 10, the lip 7d warps by a pressure difference between both chambers 9 and 10, and the communicating hole 5g is opened, and the internal pressure of the constant pressure chamber 9 is released to the transforming chamber 10. Thus, the internal pressure of the constant pressure chamber 9 is reduced.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
