Document Type and Number:
WIPO Patent Application WO/2019/182005
Kind Code:
A1
Abstract:
Provided are a fitting member that prevents the occurrence of unbonded parts, an annular member, a bonding agent member, and a method for manufacturing the bonding agent member. In a fitting member 10, fitting projections 10p that project to the outside are provided to an outer-side surface 10s of the fitting member 10. In an annular member 20, a space 20h is formed into which the fitting member 10 is fitted, the contour 20hD of the space 20h in the portion into which the fitting member 10 is fitted being formed to be slightly smaller than the contour 10D of the outer-side surface 10s of the fitting member 10, and annular projections 20p are provided to an inner surface 20f of the annular member 20. When the fitting member 10 is fitted at a preset depth into the space 20h of the annular member 20, the fitting projections 10p and the annular projections 20p fill an unbonded part that can occur in a case where the fitting projections 10p and the annular projections 20p are not present. A bonding agent member 30 is configured by the fitting member 10 being fitted into the space 20h of the annular member 20 at the preset depth, and by a contact portion between the fitting member 10 and the annular member 20 being bonded in a solid phase.
