Abstract
An operating shaft is provided in its rear side portion with a convex portion protruding from a shaft portion in the direction orthogonal to an axial direction. A bearing portion is provided with a concave portion connected to a hole through which the shaft portion is inserted and allowing the convex portion to be inserted therethrough in the axial direction. The convex portion protruding from a rear end of the bearing portion is retained to the rear end of the bearing portion other than the concave portion. The operating shaft can be finally assembled. Like a coil spring, a movable member, and a cover, the operating shaft can be assembled in a stacking manner. It is thus possible to provide an EGR sensor which has good productivity and is inexpensive, as compared with a conventional EGR sensor.
