Title:
CONNECTED PART SEAL STRUCTURE, AND SEAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2018/110094
Kind Code:
A1
Abstract:
A connected part seal structure (1) that connects a first connected part (11) and a second connected part (21) via a seal member (31). The taper angles (θ11, θ12) of first and second inner pressure-contact tapered parts (31h, 31i) that are provided on the seal member (31) are smaller than the taper angles (θ1, θ2) of first and second inner tapered parts (14a, 24a) that are provided on the first and second connected parts (11, 21). As a result, the pressure-contact force of first and second inside tapered pressure-contact margins (P1, P2) increases toward base end parts (17a, 27a) of first and second annular protrusions (17, 27).
