Abstract:
There is provided a control valve including a casing, a rotor that has a rotary shaft rotatably supported by the casing via bushings, and a sealing ring that is disposed on an inner side of each bushing in an axial direction. Both end portions of the rotary shaft are formed into stepped shapes which respectively come into contact with the bushings from the inner side in the axial direction. Areas of both the end portions of the rotary shaft projected in the axial direction are set to be equal to each other. Penetration holes which allow portions on outer sides of the sealing rings in the axial direction to be open to the atmosphere are respectively formed on a bottom wall portion and a lid body of the casing.

Claim (Index 2):
The control valve according to  claim 1 ,\n wherein the rotary shaft has an outer shaft portion which is formed integrally with the valve tube portion and with which the first sealing ring and the second sealing ring are in tight contact, and an inner shaft portion which is insert-molded on an inner side of the outer shaft portion in a radial direction, is rotatably supported by the first bearing and the second bearing, and has rigidity higher than the rigidity of the outer shaft portion, and wherein surfaces of the outer shaft portion facing the outside in the axial direction respectively configure the first stepped surface and the second stepped surface.
