Abstract: A butterfly valve 100 provided in a flow path for a first fluid flowing through a heat exchanger. The butterfly valve 100 includes: a valve plate 110 provided in the flow path; a shaft 120 for rotatably supporting the valve plate 110 in the flow path; and at least one valve plate auxiliary member 130 in contact with at least one plate surface 111a, 111b of the valve plate 100, the valve plate auxiliary member 130 having an extending portion 131 extending radially outwardly from an outer peripheral surface 112 of the valve plate 110. The valve plate auxiliary member 130 is made of a material having a lower Young's modulus than that of the valve plate 110.

Abstract: A fastener stringer includes a row of elements on which cured coating film is formed at sites where it is difficult to be coated by a roll coating method, preferably over the entire exposed surface, without incorporating any conductive wire in a fastener tape. A fastener stringer includes a row of elements and a fastener tape, at least one side edge of the fastener tape having insulation properties, the row of the elements being attached to the one side edge of the fastener tape, wherein each element includes a pair of leg portions and a head portion, the head portion having an engaging region for engaging with an opposing element when constructing a fastener chain, and wherein cured coating film is formed at least at a center portion in a front and back direction of the fastener tape on an end surface of the head portions.
