Abstract
A supercharge pressure control apparatus comprises a crimped member for securing an enclosure to a mounting member fixed in an internal combustion engine by crimping, a notch formed at one end portion of the crimped member for preventing the end portion from becoming cracked, a diaphragm disposed inside the enclosure for partitioning the interior of the enclosure into a first pressure room and a second pressure room, a holder disposed on the diaphragm and inside the second pressure room, a spring disposed inside the second pressure room for urging the diaphragm in the direction of the first pressure room or in the opposite direction through the holder, and a rod which is able to move backward and forward in accordance with the pressure of gas applied to the first pressure room for controlling the pressure of air to be supplied into the internal combustion engine. Furthermore, the mounting member has a generally circle-shaped hole through which the rod is penetrated, and the crimped member is crimped over an edge portion of the mounting member surrounding the hole so as to rigidly secure the enclosure to the mounting member.
