Servomotor for use in motor vehicle, has fold formed towards exterior at part of cover to be interlocked in cylinder, where part of wall of diaphragm is sandwiched between internal wall of cylinder and external edge of fold

摘要

The servomotor has a cover (2) and a cylinder (3) connected by an elastic interlocking system. A fold is formed towards exterior at a part of the cover to be interlocked in the cylinder. A relief (14) of an end of an internal face of the cylinder is embedded along a relief (11) situated on an external edge (8) of the fold. An internal edge and the external edge of the fold are near at an interlocked state. A part (17) of a wall of a diaphragm (4) is sandwiched between an internal wall of the cylinder and the external edge of the fold. An independent claim is also included for a method for assembling a servomotor.
