Abstract: A valve device includes a first valve element and a second valve element. The first valve element has a first sliding surface which is opposed to the second valve element. The second valve element has a second sliding surface which is opposed to the first valve element. The first sliding surface and the second sliding surface are configured to slide relative to each other to change an opening degree of an opening between a first flow passage and a second flow passage. An edge portion of at least one sliding surface among the first sliding surface and the second sliding surface is joined to a sloped surface which is sloped by an acute angle relative to a mating sliding surface which is another sliding surface among the first sliding surface and the second sliding surface and mates with the at least one sliding surface.

Abstract: A valve device includes a drive device, a valve element, a housing main body, a main-body cover and a seal member. The housing main body has a main-body connecting portion and a main body fastening portion. The main-body cover has a cover connecting portion and a cover fastening portion. At least one of the housing main body and the main-body cover has a corresponding one of: a rigidity reducing structure that reduces a rigidity of the main-body connecting portion; and a rigidity reducing structure that reduces a rigidity of the cover connecting portion. The rigidity reducing structure is a space that reduces the rigidity.
