Abstract
An annular seal memberis formed by overlapping, in the axial direction D, a plurality of ring-shape partswhich are closed or unclosed when viewed in a radial direction Dorthogonal to the axial direction Dof the annular seal member. A seal groovehas a groove bottomwith an outer diameter Rthat increases along the axial direction D. The inner peripheryof the annular seal membercontacts the groove bottom, and the inner diameter Rof the inner peripheryincreases as the outer diameter Rof the groove bottomincreases. By this means, the outer diameter Rof the outer peripheryincreases, and the side of the outer peripheryof the annular seal memberthat has a smaller outer diameter Rdoes not contact the inner peripheral wallof an inner peripheral wall member, and the side of the outer peripheryof the annular seal memberthat has a greater outer diameter Rdoes contact the inner peripheral wallof the inner peripheral wall member
