ABSTRACT:
In order that an EGR valve device for internal combustion engines of automobiles can be manufactured in a compact size and at a low cost and also that its valve member can be immediately brought to its valve-closing position whenever the driving motor of the device fails, the EGR valve device comprises a sector-shaped gear operatively coupled to a valve member urged to close the valve and capable of causing the valve member to make opening and closing movements, and a driving motor whose shaft of rotary member is disposed so as to intersect at right angles a plane containing the sector-shaped gear and is provided with a pinion meshed with the sector-shaped gear.
