Abstract
A surface material (30) is wrapped along a circumferential direction of a ring part (12) in a region of at least a portion of the ring part (12). In a state in which a foamed resin or an elastomer is die-molded, a cross-sectional shape of a planar surface orthogonal to an axial direction of the ring part (12) is formed to be a C shape or a U shape, and a parting line (36) is formed on an outer surface. In a state of being wrapped on the ring part (12), the parting line (36) is disposed on a surface facing the ring part (12).
Claims19
A surface material (30, 50, 60, 80), wrapped along a circumferential direction of a shaft member (12, 72) in a region of at least a portion of the shaft member,
- wherein, in a state in which a foamed resin or an elastomer is die-molded, a cross-sectional shape of a planar surface orthogonal to an axial direction of the shaft member is formed to be a C shape or a U shape, and a parting line (36) is formed on an outer surface, and
- in a state of being wrapped around the shaft member, the parting line is disposed on a surface facing the shaft member.
A surface material, wrapped along a circumferential direction of a shaft member in a region of at least a portion of the shaft member,
- wherein a cross-sectional shape of a planar surface orthogonal to an axial direction of the shaft member is formed in a C shape or a U shape, and
- a parting line is formed on an inner surface.
A method for wrapping a surface material, comprising:
- a molding process (S1) of forming a surface material in which a cross-sectional shape is formed in a C shape or a U shape through die-molding of a foamed resin or an elastomer and which has a parting line on an outer surface;
- and
- a wrapping process (S5) of turning over an inner surface and an outer surface of the surface material to be wrapped around an outer surface of a shaft member.
