Abstract
A stay for headrest includes a hollow metallic stay body, and an end installation body. The stay body is formed as a letter-“U” shape including a base, and paired legs extending respectively from opposite ends of the base. The end installation body is formed of a polymeric material, and includes a solid portion arranged inside a hollow interior in a leading end portion of the paired legs, and a spherical portion protruding from the leading end portion of the paired legs.

A stay for headrest, the stay comprising:
- a metallic hollow stay body formed as a letter-“U” shape including a base and paired legs extending respectively from opposite ends of the base;
- and
- an end installation body formed of a polymeric material, and including a solid portion arranged inside a hollow interior in a leading end portion of the paired legs, and a spherical portion protruding from the leading end portion of the paired legs, wherein
- the leading end portion of the paired legs includes a radially-reduced section reduced radially toward each of central axial lines of the paired legs in both of an inner peripheral face and an outer peripheral face thereof,
- the outer peripheral face of the radially-reduced section forms part of a hemispherical shape,
- the spherical portion of the end installation body is formed continually from an end in the outer peripheral face of the radially-reduced section, and forms a remaining other part of the hemispherical shape,
- the radially-reduced section and the spherical portion form the hemispherical shape, and
- the solid portion is locked to the inner peripheral face of the radially-reduced portion in a direction of the central axial lines.
