Document Type and Number:
WIPO Patent Application WO/2021/205691
Kind Code:
A1
Abstract:
A hose according to the present invention comprises an intermediate rubber layer 13 and a pair of reinforcing layers 12 that are respectively adjacent to the inner circumferential side and the outer circumferential side of the intermediate rubber layer 12. At least one of the pair of reinforcing layers is formed from a steel cord 120 obtained by twisting a plurality of steel filaments 121 together. When a gap width constituting the distance between contact points of a circumscribed circle of the steel cord and a pair of steel filaments, from among the plurality of steel filaments, that are located furthest circumferentially outward and contact each other, is defined as A (mm), a gap depth constituting the distance from an external common tangent of a pair of steel filaments to a contact point between the pair of steel filaments, is defined as B (mm), and the thickness of the intermediate rubber layer is defined as C (mm), then the equation (A/B)×C≥1.11 (mm) is satisfied.
