1. A valve device comprising:
a housing;
a stator disposed in the housing and defining at least one passage hole through which a fluid flows;
a driving portion configured to generate a rotational force;
a shaft configured to be rotated by the rotational force generated by the driving portion; and
a rotor disposed to be in contact with the stator in the housing and configured to adjust an amount of the fluid flowing through the at least one passage hole by rotating about an axis along with a rotation of the shaft, wherein
the housing has an inner circumferential side surface,
the stator has an outer circumferential side surface facing the inner circumferential side surface of the housing,
the stator has at least one engaging protrusion protruding from the outer circumferential side surface toward the inner circumferential side surface of the housing,
the housing has at least one engaging recess on the inner circumferential side surface,
the at least one engaging protrusion is engaged with the at least one engaging recess such that the stator is restricted from rotating in a circumferential direction of the axis,
the housing includes a cylindrical body portion having a housing axis that extends along the axis,
a first virtual plane is defined as a plane that connects the axis and the housing axis in a radial direction of the housing axis, the axis and the housing axis extending on the first virtual plane,
a second virtual plane is defined as a plane that is perpendicular to the first virtual plane and that passes through the housing axis in the radial direction, the housing axis extending on the second virtual plane,
the stator includes a stator body portion having a stator axis that extends along the axis,
the second virtual plane passes through the stator body portion such that the stator body portion is virtually divided by the second virtual plane into two areas, and
the stator is disposed inside the cylindrical body portion of the housing such that the at least one engaging protrusion is located in one of the two areas and the stator axis is located in the other of the two areas.
