Claim 11:
12. A valve device comprising:
a housing integrally or separately having a flow path formation part where at least one flow path hole through which a fluid passes is formed;
a drive part that outputs a rotational force; and
a rotation part that rotates about a predetermined axis by the rotational force output from the drive part,
the rotation part includes
a shaft and a rotor that increases or decreases an opening degree of the flow path hole with rotation of the shaft,
at least a part of the rotation part is rotatably held by the housing,
the shaft has a one-end-side portion to which the rotational force is transmitted from the drive part and an other-end-side portion opposite to the one-end-side portion in an axial direction of the shaft,
at least a part of the other-end-side portion is rotatably held by the housing,
the rotation part includes an intermediate element that couples the rotor to the shaft such that a gap is formed between the other-end-side portion and the rotor,
the gap is formed between the other-end-side portion and the rotor in a radial direction of the shaft, and
the housing has an end reception part that receives at least a part of the other-end-side portion.
